# ADR-0002: Singleton Prisma Client Pattern
## Status
Accepted
## Context
The application was creating multiple `PrismaClient` instances across different service files. This led to:
- Multiple database connection pools
- Potential connection exhaustion
- Inconsistent connection management
- Difficulties in monitoring and debugging database connections
## Decision
Implement a singleton pattern for Prisma Client to ensure:
- Single connection pool across the application
- Proper connection lifecycle management
- Graceful shutdown handling
- Development hot-reload compatibility
The singleton is implemented in `src/shared/database/prisma.ts` and exported for use across the application.
## Consequences
### Positive
- Single connection pool reduces resource usage
- Consistent connection management
- Easier to monitor and debug
- Proper cleanup on application shutdown
- Works correctly with development hot-reload
### Negative
- Requires refactoring existing code (381 files identified)
- All services must import from shared location
- Potential for circular dependencies if not careful
### Risks
- Large refactoring effort required
- Need to ensure all services are updated
- Must maintain backward compatibility during migration
## Decision Tree
```mermaid
graph TD
START[Need Database Connection Management]
START --> Q1{Connection Pool<br/>Issues?}
Q1 -->|Yes| Q2{Refactoring<br/>Acceptable?}
Q1 -->|No| ALT1[Keep Multiple Clients]
Q2 -->|Yes| Q3{Need DI<br/>Framework?}

# ADR-0003: Environment Variable Validation at Startup
## Status
Accepted
## Context
The application was using environment variables without validation, leading to:
- Runtime errors when required variables were missing
- Security risks from weak or missing secrets
- Difficult debugging when misconfigured
- No clear error messages for configuration issues
## Decision
Implement environment variable validation that:
- Runs at application startup
- Validates all required variables
- Provides clear error messages
- Supports different validation rules per environment
- Fails fast if critical variables are missing or invalid
## Consequences
### Positive
- Early detection of configuration errors
- Clear error messages guide developers
- Prevents runtime failures from misconfiguration
- Security improvements (validates JWT secret strength, CORS config)
- Better developer experience
### Negative
- Application won't start if validation fails (by design)
- Requires maintaining validation schema
- Additional startup time (minimal)
### Risks
- Breaking changes if validation rules are too strict
- Need to keep validation in sync with actual usage
## Alternatives Considered
1. **Runtime Validation**: Validate when variables are used
- Pros: More flexible
- Cons: Errors discovered late, harder to debug
2. **Configuration File**: Use config file instead of env vars
- Pros: Type-safe, validated
- Cons: Doesn't work well with 12-factor app principles
3. **Startup Validation**: Chosen approach
- Pros: Fail fast, clear errors, secure defaults
- Cons: None significant
## Implementation
- Created `src/shared/config/env-validator.ts`
- Integrated into `src/index.ts` startup
- Validates: DATABASE_URL, JWT_SECRET, ALLOWED_ORIGINS, etc.

# ADR-0004: Zero-Trust Authentication Strategy
## Status
Accepted
## Context
The DBIS Core Banking System requires secure authentication for all API requests. Traditional authentication methods are insufficient for sovereign-grade financial infrastructure that handles:
- Multi-sovereign operations
- High-value transactions
- Regulatory compliance requirements
- Cross-border operations
## Decision
Implement a zero-trust authentication strategy using:
1. **Sovereign Identity Tokens (SIT)**: JWT-based tokens with sovereign bank identity
2. **Request Signature Verification**: HSM-backed cryptographic signatures for each request
3. **Multi-layer Validation**: Token validation + signature verification + timestamp/nonce checks
4. **HSM Integration**: Hardware Security Module for key management and signing
## Consequences
### Positive
- Strong security with multiple validation layers
- HSM-backed cryptographic operations
- Replay attack prevention (timestamp/nonce)
- Sovereign identity verification
- Scalable across multiple sovereign banks
### Negative
- More complex implementation
- Requires HSM infrastructure
- Slightly higher latency per request
- More complex client implementation
### Risks
- HSM availability dependency
- Signature verification performance at scale
- Key rotation complexity
## Alternatives Considered
1. **Simple JWT Only**: Basic JWT authentication
- Pros: Simple, fast
- Cons: Insufficient security for financial operations
2. **API Keys**: Static API keys
- Pros: Very simple
- Cons: No cryptographic verification, weak security
3. **Zero-Trust with HSM**: Chosen approach
- Pros: Strong security, regulatory compliance, sovereign-grade
- Cons: More complex
## Implementation
- JWT tokens with sovereign bank identity
- Request signature headers (X-SOV-SIGNATURE, X-SOV-TIMESTAMP, X-SOV-NONCE)
- HSM service integration for signature verification
- Middleware: `zeroTrustAuthMiddleware` in `src/integration/api-gateway/middleware/auth.middleware.ts`

## Relationship to Implementation Documentation
The Atlas supplements work in conjunction with implementation documentation:
```
Atlas Supplement (Architecture) → Sub-Volume/Volume (Implementation)
```
For example:
- **Supplement B** (Atlas) describes the MetaverseDubai rail map and integration framework
- **Sub-Volume C** (Implementation) provides the actual services, APIs, and database schemas
Use the Atlas to understand **how systems connect and flow**, and use the implementation documentation to understand **how to build and use** those systems.

# DBIS Architecture Atlas — Supplement A
# GRU Monetary System & Bond Architecture (Li99PpOsB10 / Li99PpAvB10)
This supplemental atlas section provides a full architectural mapping of the **Global Reserve Unit (GRU)**, its internal monetary hierarchy, and its integration into DBIS' multiversal liquidity and settlement systems. It also documents the structure and operational mechanics of the **Li99PpOsB10** and **Li99PpAvB10** perpetual bond instruments.
---
## 1. GRU MONETARY STRUCTURE (FULL HIERARCHY)
### 1.1 GRU Unit Definitions
```
1 M00 GRU = 5 M0 GRU
1 M00 GRU = 25 M1 GRU
1 M00 GRU = x M0 GRU + y M1 GRU (user-defined hybrid model)
```
### 1.2 GRU Valuation Rule

## Step-by-Step Process
### Step 1: Sanctions Screening
1. Receive screening request with:
- Sovereign bank ID
- Transaction ID
- Entity name (optional)
- Entity type (optional)
2. Initialize risk score: `0`
3. Initialize screening results object
4. If entity name provided:
- Check sanctions lists:
- OFAC (Office of Foreign Assets Control)
- EU sanctions list
- UN sanctions list
- Query sanctions database
- If match found:
- Set `sanctionsMatch: true` in results
- Add risk score: `+100` (critical match)
5. Store sanctions check result
**Code Reference**: `src/core/compliance/aml.service.ts:19-82`
### Step 2: PEP Screening
1. If entity name provided:
- Check PEP (Politically Exposed Person) database
- Query PEP list by entity name
- If match found:
- Set `pepMatch: true` in results
- Add risk score: `+50` (high risk)
2. Store PEP check result
**Code Reference**: `src/core/compliance/aml.service.ts:37-44`
### Step 3: Pattern Detection
1. Analyze transaction for anomalous patterns:
- Transaction velocity (frequency)
- Amount patterns
- Geographic patterns
- Time-based patterns
2. Detect specific patterns:
- Circular transfers (money going in circles)
- Synthetic layering (complex transaction chains)
- Structuring (breaking large amounts into smaller)
- Rapid movement (velocity anomalies)
3. Calculate pattern risk score:
- Each pattern adds to risk score
- Pattern severity determines weight
4. Store pattern risk in results
**Code Reference**: `src/core/compliance/aml.service.ts:46-49`
### Step 4: AML Behavior Monitoring
1. Call RegTech supervision engine:
- Pass transaction ID
- Pass sovereign bank ID
- Request AML behavior monitoring
2. Supervision engine evaluates AML rules:
- Retrieves active AML behavior rules
- Evaluates each rule against transaction
- Returns triggered behaviors
3. Process behavior results:
- Filter critical behaviors (severity: `critical`)
- For each critical behavior:
- Add risk score: `+50`
- Store all behaviors in results
4. Store AML behavior results
**Code Reference**:
- `src/core/compliance/aml.service.ts:51-57`
- `src/core/compliance/regtech/supervision-engine.service.ts:22-50`
### Step 5: Risk Score Calculation
1. Sum all risk components:
- Sanctions match: `+100` (if match)
- PEP match: `+50` (if match)
- Pattern risk: variable
- Critical AML behaviors: `+50` each
2. Total risk score = sum of all components
### Step 6: Status Determination
1. Determine compliance status based on risk score:
- **CLEAR**: Risk score < 50
- **FLAGGED**: Risk score >= 50 and < 100
- **BLOCKED**: Risk score >= 100
2. Status thresholds:
- `AML_RISK_CRITICAL`: 100
- `AML_RISK_HIGH`: 50
**Code Reference**: `src/core/compliance/aml.service.ts:59-65`
### Step 7: Create Compliance Record
1. Create compliance record in database:
- Sovereign bank ID
- Transaction ID
- Record type: `AML_CHECK`
- Entity name (if provided)
- Entity type (if provided)
- Risk score
- Status (CLEAR, FLAGGED, or BLOCKED)
- Screening result (all check results)
- Timestamp
2. Return compliance record
**Code Reference**: `src/core/compliance/aml.service.ts:67-82`
## Error Handling
### Error: Transaction Not Found
- **Detection**: Transaction ID doesn't exist
- **Action**: Continue screening with available data
- **Recovery**: Verify transaction ID
### Error: Sanctions Database Unavailable
- **Detection**: Cannot query sanctions list
- **Action**: Log warning, continue with other checks
- **Recovery**: Retry sanctions check, use cached data
### Error: RegTech Engine Unavailable
- **Detection**: Supervision engine returns error
- **Action**: Log warning, continue without AML behavior check
- **Recovery**: Retry AML behavior monitoring
### Error: Pattern Detection Failure
- **Detection**: Pattern analysis throws error
- **Action**: Set pattern risk to 0, continue
- **Recovery**: Investigate pattern detection service

# Atomic Settlement Flow
## Overview
Atomic settlement ensures that cross-chain and cross-ledger transactions either complete entirely or fail entirely, with no partial state. This flow implements a dual-commitment protocol that commits to both sovereign and DBIS master ledgers atomically.
## Prerequisites
- Source and destination banks are registered
- Valid transaction request
- Sufficient balance in source account
- Both ledgers (sovereign and DBIS) are operational
- Atomic settlement service initialized
## Visual Flow Diagram

└─────────────┘
```
## Step-by-Step Process
### Step 1: Prepare Dual-Commitment
1. Receive atomic settlement request with:
- Source bank ID
- Destination bank ID
- Amount and currency
- Asset type
- Transaction ID (optional)
2. Generate unique settlement ID: `{uuid}`
3. Generate transaction ID if not provided: `{uuid}`
4. Create commitment data structure:
- Settlement ID
- Transaction details
- Timestamp
- Nonce for uniqueness
5. Prepare commitment hash input
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:33-42`
### Step 2: Commit to Sovereign Ledger
1. Post to sovereign ledger:
- Lookup source account in sovereign bank
- Lookup destination account
- Create debit entry on source
- Create credit entry on destination
- Use ledger ID: `Sovereign_{sourceBankId}`
2. Retrieve ledger entry
3. Extract block hash from ledger entry
4. Store sovereign ledger hash
5. If posting fails, throw error and terminate
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:44-49`
### Step 3: Commit to DBIS Master Ledger
1. Post to DBIS master ledger:
- Lookup source account
- Lookup destination account
- Create debit entry on source
- Create credit entry on destination
- Use ledger ID: `Master`
- Include metadata: `{ atomicSettlement: true, settlementId }`
2. Retrieve ledger entry
3. Extract block hash from ledger entry
4. Store DBIS ledger hash
5. If posting fails, rollback sovereign ledger and throw error
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:51-52`
### Step 4: Verify Dual-Commitment
1. Compare hashes:
- Retrieve sovereign ledger hash
- Retrieve DBIS ledger hash
- Verify both hashes exist and are non-empty
2. Verify ledger entries:
- Query sovereign ledger entry by hash
- Query DBIS ledger entry by hash
- Verify both entries exist
- Verify entry details match (amount, accounts, etc.)
3. If verification fails:
- Rollback both ledger entries
- Mark settlement as failed
- Throw error
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:54-58`
### Step 5: Finalize Settlement
1. Calculate settlement time:
- Start time recorded at Step 1
- End time = current time
- Settlement time = end - start
2. Create atomic settlement record:
- Settlement ID
- Transaction ID
- Source and destination bank IDs
- Amount, currency, asset type
- Settlement mode: `atomic`
- Dual-ledger commit: `true`
- Sovereign ledger hash
- DBIS ledger hash
- Settlement time (milliseconds)
- Status: `settled`
- Committed and settled timestamps
3. Return settlement result with:
- Settlement ID
- Status: `settled`
- Both ledger hashes
- Settlement time
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:60-90`
### Step 6: Error Handling
1. If any step fails:
- Create failed settlement record
- Set status: `failed`
- Set dual-ledger commit: `false`
- Record error details
2. Rollback any partial ledger entries:
- If sovereign posted but DBIS failed: rollback sovereign
- If DBIS posted but verification failed: rollback both
3. Log error for investigation
**Code Reference**: `src/core/settlement/isn/atomic-settlement.service.ts:91-111`
## Error Handling
### Error: Commitment Preparation Failure
- **Detection**: Cannot generate commitment
- **Action**: Return error, terminate flow
- **Recovery**: Verify input parameters, retry
### Error: Sovereign Ledger Post Failure
- **Detection**: Ledger posting fails
- **Action**: Terminate flow, no rollback needed
- **Recovery**: Verify ledger availability, check account status
### Error: DBIS Ledger Post Failure
- **Detection**: DBIS posting fails after sovereign posted
- **Action**: Rollback sovereign ledger entry
- **Recovery**: Retry after verifying DBIS ledger status
### Error: Dual-Commitment Verification Failure
- **Detection**: Hashes don't match or entries missing
- **Action**: Rollback both ledger entries
- **Recovery**:
- Investigate ledger integrity
- Verify hash generation
- Retry settlement
### Error: Concurrent Modification
- **Detection**: Account balance changed during settlement
- **Action**: Rollback and retry
- **Recovery**: Implement optimistic locking
## Integration Points
### Related Services

- **LIMIT order**: Use provided limit price
- Verify limit price is provided
- Use limit price directly
2. If MARKET order and price unavailable:
- Throw error "Market price not available"
3. If LIMIT order and limit price missing:
- Throw error "Invalid order type or missing limit price"
**Code Reference**: `src/core/fx/fx.service.ts:29-37`
### Step 3: Create FX Trade Record
1. Generate unique trade ID: `FX-{uuid}`
2. Create FX trade record:
- Trade ID
- Sovereign bank ID
- FX pair ID
- Base currency (from pair)
- Quote currency (from pair)
- Trade type: `SPOT` (default)
- Quantity: order amount
- Price: calculated price

2. Verify trade exists and is in `pending` status
3. Update trade record:
- Status: `executed`
- Executed at: current timestamp
4. Map trade to FxTrade type
5. Return executed trade details
**Code Reference**: `src/core/fx/fx.service.ts:67-87`
### Step 5: Market Price Calculation (for MARKET orders)
1. Parse pair to extract base and quote currencies
2. Get market price:
- In production: fetch from market data feeds
- Use VWAP (Volume Weighted Average Price) or TWAP (Time Weighted Average Price)
- Currently: return mock prices for known pairs
3. Return price as string
**Code Reference**: `src/core/fx/fx.service.ts:92-105`
### Step 6: VWAP/TWAP Calculation (optional)
1. **VWAP Calculation**:
- Get trade history for pair within time window (default 3600s)
- Calculate: `VWAP = Σ(price × volume) / Σ(volume)`
- Return VWAP price
2. **TWAP Calculation**:
- Get price history for pair within time window
- Calculate: `TWAP = Σ(price × time_weight) / Σ(time_weight)`

```
## Step-by-Step Process
### Step 1: Payment Initiation
1. Payment initiator submits payment request via API or ISO 20022 message (PACS.008)
2. GPN message handler receives and validates message format
3. Extract payment details:
- Source account (debtorAccount)
- Destination account (creditorAccount)
- Amount and currency
- Payment priority
- Reference information
**Code Reference**: `src/core/payments/payment.service.ts:18-73`
### Step 2: Layer 1 - Sovereign Access Authentication
1. Extract SDIP from request headers or message
2. Verify SDIP signature using sovereign identity service
3. Validate sovereign bank ID matches SDIP
4. Check zero-trust authentication:
- Verify request signature
- Validate timestamp (prevent replay attacks)
- Check access permissions
5. Segment traffic by sovereign identity
**Code Reference**: `src/integration/api-gateway/middleware/auth.middleware.ts`
### Step 3: Account Validation
1. Lookup source account (debtorAccount) by account number
2. Lookup destination account (creditorAccount) by account number
3. Verify both accounts exist and are active
4. Check source account balance:
- Calculate available balance
- Verify sufficient funds for payment amount
- Consider any pending holds or reserves
5. If insufficient balance, return error and terminate flow
**Code Reference**: `src/core/accounts/account.service.ts`
### Step 4: Layer 2 - Global Switching & Routing
1. Calculate optimal route using:
- FX cost optimization
- Liquidity availability check
- SRI-based risk weighting
- Settlement mode (RTGS vs DNS)
2. Determine settlement mode based on priority:
- RTGS for urgent/high-priority payments
- DNS for normal/deferred payments
3. Select routing path:
- Direct SCB-to-SCB if same currency
- Via GSS if cross-currency
- Via SSU if optimal for cross-border
4. Create payment routing record
**Code Reference**: `src/core/settlement/sire/sire-routing.service.ts`
### Step 5: Layer 3 - Finality & Settlement
1. Create hash-lock for atomic settlement:
- Generate commitment hash
- Store hash-lock record
2. Post to SCB sovereign ledger:
- Create debit entry on source account
- Create credit entry on destination account
- Generate sovereign ledger hash
3. Post to DBIS master ledger:
- Create corresponding entries
- Generate DBIS ledger hash
4. Verify hash-lock match:
- Compare sovereign and DBIS hashes
- Verify dual-ledger commit
5. Mark payment as settled
**Code Reference**:
- `src/core/settlement/gss/gss-master-ledger.service.ts:35-96`
- `src/core/ledger/ledger-lifecycle.service.ts:44-139`
### Step 6: Confirmation & Notification
1. Generate payment status report (PACS.002)
2. Send confirmation to payment initiator
3. Notify destination bank (if different sovereign)
4. Update payment status in database
5. Log settlement event
## Error Handling
### Error: Account Not Found
- **Detection**: Account lookup returns null
- **Action**: Return error code `NOT_FOUND`
- **Recovery**: Terminate flow, notify initiator
### Error: Insufficient Balance
- **Detection**: Available balance < payment amount
- **Action**: Return error code `VALIDATION_ERROR`
- **Recovery**: Terminate flow, suggest alternative payment methods
### Error: Authentication Failure
- **Detection**: SDIP verification fails
- **Action**: Return error code `UNAUTHORIZED`
- **Recovery**: Terminate flow, log security event
### Error: Routing Failure
- **Detection**: No valid route found
- **Action**: Return error code `ROUTING_ERROR`
- **Recovery**: Retry with alternative routing, escalate if persistent
### Error: Dual-Ledger Commit Failure
- **Detection**: Hash-lock verification fails
- **Action**: Rollback both ledger entries
- **Recovery**:
- Mark payment as failed
- Create reconciliation record
- Notify operations team

```
## Step-by-Step Process
### Step 1: Settlement Entry Creation
1. Receive settlement request with:
- Source bank ID
- Destination bank ID
- Amount and currency
- Asset type
- Optional sovereign signature
2. Generate unique entry ID: `GSS-ENTRY-{uuid}`
3. Validate node configuration for source bank
4. Verify both banks are active SCBs
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:35-38`
### Step 2: Layer 1 - Sovereign Ledger Posting
1. Lookup source accounts:
- Filter by sovereign bank ID
- Match currency code and asset type
- Select active account
2. Lookup destination accounts:
- Filter by sovereign bank ID
- Match currency code and asset type
- Select active account
3. Post double-entry to sovereign ledger:
- Debit source account
- Credit destination account
- Use ledger ID: `Sovereign_{sourceBankId}`
- Transaction type: `Type_A`
4. Retrieve ledger entry and extract block hash
5. Store sovereign ledger hash
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:101-150`
### Step 3: Layer 2 - DBIS Master Ledger Posting
1. Lookup source accounts (same as Step 2)
2. Lookup destination accounts (same as Step 2)
3. Post double-entry to DBIS master ledger:
- Debit source account
- Credit destination account
- Use ledger ID: `Master`
- Transaction type: `Type_A`
- Metadata: `{ gssEntry: true, masterLedger: true }`
4. Retrieve ledger entry and extract block hash
5. Store DBIS ledger hash
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:155-203`
### Step 4: Layer 3 - Sovereign Signature Validation (if provided)
1. Check if sovereign signature is provided
2. If provided:
- Lookup sovereign identity by bank ID
- Verify identity type is 'Settlement'
- Validate signature using HSM (in production)
- Verify signature matches entry data
3. If validation fails, throw error and rollback
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:208-232`
### Step 5: Layer 4 - Master Entry Creation & Finality
1. Create GSS master ledger entry with:
- Entry ID
- Node ID
- Source and destination bank IDs
- Amount, currency, asset type
- Sovereign signature (if provided)
- Dual-ledger commit flag: `true`
- Sovereign ledger hash
- DBIS ledger hash
- Status: `settled`
- Committed and settled timestamps
2. Verify dual-ledger synchronization:
- Both hashes exist
- Both ledger entries exist
- Dual-commit flag is true
3. Return dual-ledger result
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:52-77`
### Step 6: Error Handling (if any step fails)
1. If error occurs after Step 1:
- Create failed entry record
- Set dual-ledger commit: `false`
- Set status: `failed`
- Log error details
2. Rollback any partial ledger entries
3. Throw error to caller
**Code Reference**: `src/core/settlement/gss/gss-master-ledger.service.ts:78-95`
## Error Handling
### Error: Accounts Not Found
- **Detection**: Account lookup returns empty array
- **Action**: Throw error "Accounts not found for sovereign ledger posting"
- **Recovery**: Verify account configuration, retry with correct parameters
### Error: Sovereign Signature Invalid
- **Detection**: Signature validation fails
- **Action**: Throw error "Sovereign identity not found" or "Signature invalid"
- **Recovery**: Request new signature, verify HSM configuration
### Error: Dual-Ledger Mismatch
- **Detection**: Hashes don't match or entries missing
- **Action**: Mark entry as failed, create reconciliation record
- **Recovery**: Manual reconciliation process, verify ledger integrity
### Error: Node Configuration Missing
- **Detection**: SSN not configured for source bank
- **Action**: Return error, prevent settlement
- **Recovery**: Configure SSN, retry settlement

# M-RTGS Settlement Flow
## Overview
The Multi-Asset RTGS System (M-RTGS) provides instantaneous settlement (< 100ms target) for multiple asset types (fiat, CBDC, SSU, commodities, securities) in a single synchronized settlement cycle. This flow documents the priority queue management and multi-asset settlement process.
## Prerequisites
- Payment request with valid source and destination accounts
- Sufficient balance/position in source account
- Asset type supported by M-RTGS
- M-RTGS service operational
- Queue manager initialized

```
## Step-by-Step Process
### Step 1: Payment Queue Addition
1. Receive payment request with:
- Source bank ID
- Destination bank ID
- Amount and currency
- Asset type (fiat, CBDC, SSU, commodity, security)
- Payment priority
2. Calculate priority score:
```
priority = systemic_value + fx_cost_penalty + liquidity_weight + SRI_adjustment
```
3. Determine priority tier:
- **Tier 1**: Sovereign & systemic transactions
- **Tier 2**: Interbank transactions
- **Tier 3**: Retail CBDC traffic during peak hours
4. Add payment to appropriate queue with priority score
5. Generate queue entry ID
**Code Reference**: `src/core/settlement/m-rtgs/` (queue manager service)
### Step 2: Queue Processing
1. Queue manager selects next payment based on:
- Priority tier
- Priority score within tier
- First-in-first-out for same priority
2. Lock payment entry to prevent concurrent processing
3. Verify payment still valid:
- Source account still active
- Sufficient balance available
- Destination account still active
### Step 3: Risk Monitoring
1. Check transaction velocity:
- Count transactions from source in time window
- Verify within velocity limits
2. Check liquidity congestion:
- Verify sufficient liquidity in system
- Check for liquidity bottlenecks
3. Check FX slip (if cross-currency):
- Verify FX rate stability
- Check for excessive volatility
4. Check commodity price shocks (if commodity asset):
- Verify commodity price stability
5. Check CBDC routing patterns:
- Verify no abnormal routing detected
6. If any risk check fails, flag payment and escalate
**Code Reference**: `src/core/settlement/m-rtgs/` (risk monitor service)
### Step 4: Multi-Asset Settlement Execution
1. Determine settlement method based on asset type:
- **Fiat**: Standard ledger posting
- **CBDC**: CBDC ledger posting
- **SSU**: SSU transaction service
- **Commodity**: CDT settlement service
- **Security**: Security token settlement
2. Execute multi-ledger synchronization:
- Post to source ledger
- Post to destination ledger
- Post to master ledger (if required)
3. Monitor settlement time:
- Start timer at settlement initiation
- Target: < 100ms total time
- Log if exceeds target
4. Update payment status:
- Mark as "settling" during execution
- Mark as "settled" on completion
- Record settlement timestamp
**Code Reference**:
- `src/core/settlement/m-rtgs/` (settlement service)
- `src/core/ledger/ledger.service.ts`
- `src/core/settlement/ssu/ssu-service.ts`
- `src/core/commodities/cbds/cdt-settlement.service.ts`
### Step 5: MACE Integration (if collateralized)
1. If payment requires collateral:
- Calculate required initial margin (IM):
```
IM = exposure * volatility * SRI_factor
```
- Verify collateral availability
- Allocate collateral via MACE engine
2. Update collateral positions
3. Monitor margin requirements
**Code Reference**: `src/core/settlement/m-rtgs/` (MACE integration service)
### Step 6: Settlement Confirmation
1. Verify all ledger entries posted successfully
2. Generate settlement confirmation
3. Update queue entry status
4. Release queue lock
5. Notify payment initiator
6. Log settlement event with metrics
## Error Handling
### Error: Insufficient Balance
- **Detection**: Balance check fails
- **Action**: Remove from queue, return error
- **Recovery**: Notify initiator, suggest alternative
### Error: Risk Check Failed
- **Detection**: Risk monitor flags payment
- **Action**: Hold payment, escalate to operations
- **Recovery**: Manual review, adjust risk parameters if needed
### Error: Settlement Timeout
- **Detection**: Settlement exceeds 100ms target
- **Action**: Log warning, continue processing
- **Recovery**: Investigate performance bottleneck
### Error: Multi-Ledger Sync Failure
- **Detection**: One or more ledger posts fail
- **Action**: Rollback all ledger entries
- **Recovery**: Retry settlement, escalate if persistent
### Error: Queue Lock Timeout
- **Detection**: Payment locked too long
- **Action**: Release lock, retry or fail
- **Recovery**: Investigate deadlock conditions

## Performance Metrics
- **Queue Addition**: < 10ms target
- **Priority Calculation**: < 5ms target
- **Risk Monitoring**: < 20ms target
- **Settlement Execution**: < 100ms target (total)
- **Total End-to-End**: < 135ms target
- **Throughput**: 50,000+ payments/second
- **Availability**: 99.99% uptime target
## Security Considerations
### Access Control
- Only authorized banks can submit payments
- Queue access restricted to M-RTGS service
### Data Integrity
- Queue entries locked during processing
- Multi-ledger synchronization ensures consistency
- Settlement timestamps provide audit trail
### Risk Controls
- Real-time velocity monitoring

## Testing Scenarios
### Happy Path
1. Valid payment request
2. Successful queue addition
3. Priority calculation correct
4. Risk checks pass
5. Settlement completes < 100ms
6. All ledgers synchronized
### Error Scenarios
1. Insufficient balance
2. Risk check failure
3. Settlement timeout
4. Multi-ledger sync failure

## Step-by-Step Process
### Minting Process
#### Step 1: Get or Create Default SSU
1. Receive mint request with:
- Amount to mint
- Trigger bank ID (optional)
- Transaction ID (optional)
2. Lookup default SSU:
- Search for SSU with name: "DBIS Global SSU"
- Filter by status: `active`
3. If SSU doesn't exist:
- Generate SSU ID: `SSU-{uuid}`
- Create SSU record:
- SSU ID
- SSU name: "DBIS Global SSU"
- Description: "DBIS Synthetic Settlement Unit - Global settlement asset"
- Underlying assets: empty array (initialized later)
- Status: `active`
- Initialize composition via composition service
4. Return SSU (existing or newly created)
**Code Reference**: `src/core/settlement/ssu/ssu-service.ts:46-208`
#### Step 2: Verify Liquidity for Minting
1. Validate mint amount:
- Convert to Decimal
- Verify: `amount > 0`
- If invalid, throw error: "Mint amount must be greater than zero"
2. Verify underlying asset liquidity:
- In production: check liquidity pools for:
- 40% currency reserves
- 30% commodity reserves
- 20% CBDC reserves
- 10% LAM reserves
- Currently: assume liquidity available (simplified)
3. If insufficient liquidity, throw error
**Code Reference**: `src/core/settlement/ssu/ssu-service.ts:213-221`
#### Step 3: Calculate Composition
1. Call composition service to calculate current composition:
- Pass SSU ID
- Service calculates based on:
- Current market values
- Reserve availability
- Target composition ratios
2. Composition service returns:
- Currency percentage: 40%
- Commodity percentage: 30%
- CBDC percentage: 20%
- LAM percentage: 10%
3. Store composition for this mint operation
**Code Reference**: `src/core/settlement/ssu/ssu-composition.service.ts`
#### Step 4: Create Mint Transaction
1. Call SSU transaction service to create transaction:
- SSU ID
- Transaction type: `mint`
- Amount: mint amount
- Source bank ID: trigger bank ID (if provided)
- Settlement ID: transaction ID (if provided)
2. Transaction service creates:
- Transaction ID
- Transaction record
- Links to SSU
3. Update SSU balance (if tracked):
- In production: increment SSU total supply
- Currently: simplified (balance tracking)
4. Return transaction ID
**Code Reference**: `src/core/settlement/ssu/ssu-service.ts:57-68`
### Burning Process
#### Step 1: Verify SSU Exists
1. Receive burn request with:
- SSU ID
- Amount to burn
- Reason (optional)
2. Lookup SSU by ID
3. Verify SSU exists and status is `active`
4. If not found or inactive, throw error: "SSU not found or not active"
**Code Reference**: `src/core/settlement/ssu/ssu-service.ts:74-94`
#### Step 2: Create Burn Transaction
1. Call SSU transaction service to create transaction:
- SSU ID
- Transaction type: `burn`
- Amount: burn amount
2. Transaction service creates:
- Transaction ID
- Transaction record
- Links to SSU
3. Update SSU balance (if tracked):
- In production: decrement SSU total supply
- Currently: simplified (balance tracking)
4. Return transaction ID
**Code Reference**: `src/core/settlement/ssu/ssu-service.ts:84-93`
## Error Handling
### Error: SSU Not Found
- **Detection**: SSU lookup returns null
- **Action**: Throw error "SSU not found or not active"
- **Recovery**: Verify SSU ID, create SSU if needed
### Error: SSU Inactive
- **Detection**: SSU status is not `active`
- **Action**: Throw error "SSU not found or not active"
- **Recovery**: Activate SSU, retry
### Error: Invalid Mint Amount
- **Detection**: Amount <= 0
- **Action**: Throw error "Mint amount must be greater than zero"
- **Recovery**: Correct amount, retry
### Error: Insufficient Liquidity
- **Detection**: Underlying assets don't have sufficient liquidity
- **Action**: Throw error, prevent minting
- **Recovery**: Add liquidity to pools, retry
### Error: Composition Calculation Failure
- **Detection**: Composition service returns error
- **Action**: Throw error, prevent minting
- **Recovery**: Verify composition service, retry

- `SsuComposition` - Composition records
## Performance Metrics
- **SSU Lookup/Creation**: < 10ms target
- **Liquidity Verification**: < 20ms target
- **Composition Calculation**: < 30ms target
- **Transaction Creation**: < 10ms target
- **Total End-to-End**: < 70ms target
- **Throughput**: 5,000+ operations/second
- **Availability**: 99.99% uptime target
## Security Considerations
### SSU Validation
- Only active SSUs can be used
- SSU ID verification prevents unauthorized access
### Liquidity Verification
- Ensures underlying assets available
- Prevents over-minting
- Maintains composition ratios
### Transaction Tracking
- All mint/burn operations logged
- Transaction IDs provide audit trail
- Links to source transactions
## Testing Scenarios
### Happy Path - Minting
1. Valid mint request
2. SSU exists or created
3. Sufficient liquidity
4. Composition calculated
5. Transaction created
6. SSU minted
### Happy Path - Burning
1. Valid burn request
2. SSU exists and active
3. Transaction created
4. SSU burned
### Error Scenarios
1. SSU not found
2. SSU inactive
3. Invalid mint amount
4. Insufficient liquidity
5. Composition calculation failure
### Edge Cases
1. Maximum mint amount
2. Minimum mint amount
3. Mint with zero amount (should fail)
4. Burn more than available
5. Concurrent mint/burn operations

| F2 | ±5% | Speculative pressure |
| F3 | ±12% | Sovereign stress |
| F4 | ±30% | Systemic contagion |
### 3. GRU Liquidity Loop Instability
Stress on the **7→10→9.55** liquidity cycle.
Factors:
- Spread widening
- QPS latency (pre-GAS)
- GAS atomic lock friction
- Temporal desynchronization
### 4. Sovereign Default Correlation
Multivariate scenario linking:

- t+Δ (predictive stress)
- tΩ (Ω‑Layer merged timeline)
## Simulation Tables
### GRU Price Shock Table (XAU Link)
| XAU Shock | GRU M00 | GRU M0 | GRU M1 |
|-----------|---------|--------|--------|
| +5% | +3.2% | +1.8% | +0.7% |
| +15% | +10.6% | +6.2% | +2.1% |
| +35% | +26.1% | +14.4% | +5.8% |
| +70% | +49.5% | +27.9% | +12.7% |
### GRU Bond Stress Table
| Stress Type | Li99PpOsB10 | Li99PpAvB10 | Notes |
|-------------------|-------------|-------------|-------|
| Metal Shock S3 | -12% NAV | -8% NAV | Higher metal-demand bonds stabilize |
| FX Cascade F4 | -28% NAV | -22% NAV | FX volatility increases discounting |
| Loop Instability | -16% cash | -11% cash | Liquidity loop becomes unbalanced |
| Sovereign Default | -35% fair value | -29% fair value | Supranational reserves absorb shock |
### Regional Reserve Pool Stress Table

## Algorithmic Framework
### Metal Shock Model
```
GRU_new = GRU_base * (1 + metal_shock_factor * weight)
```
### FX Cascade Model
```
f = FX_volatility + correlation_matrix * shock_vector
```
### Liquidity Loop Instability Model
```
loop_outcome = (capital * 10/7 * 0.955) ^ cycles

# Plugin Development Guide
## Overview
This guide explains how to develop custom plugin adapters for integrating core banking systems with the DBIS Nostro/Vostro API.
## Plugin Architecture
### Base Adapter Interface
All plugins must implement the `IPluginAdapter` interface:
```typescript
interface IPluginAdapter {
getName(): string;
getVersion(): string;
isAvailable(): Promise<boolean>;
mapParticipant(internalData: unknown): ParticipantCreateRequest;
mapAccount(internalData: unknown): AccountCreateRequest;
mapTransfer(internalData: unknown): TransferCreateRequest;
mapTransferToInternal(transfer: NostroVostroTransfer): unknown;
mapAccountToInternal(account: NostroVostroAccount): unknown;
postTransfer(transfer: NostroVostroTransfer): Promise<{success: boolean; internalId?: string; error?: string}>;
getAccountBalance(accountId: string): Promise<{balance: string; available: string; hold: string}>;
reconcile(accountId: string, asOfDate: Date): Promise<{matched: number; breaks: unknown[]}>;
}
```
### Base Class
Extend `BasePluginAdapter` for common functionality:
```typescript
import { BasePluginAdapter } from '@/integration/plugins/generic-adapter';
export class MyCustomAdapter extends BasePluginAdapter {
constructor(config: Record<string, unknown> = {}) {
super('MyCustomAdapter', '1.0.0', config);
}
// Implement required methods
}
```
## Implementation Steps
### 1. Create Adapter Class
```typescript
// src/integration/plugins/my-custom-adapter.ts
import { BasePluginAdapter } from './generic-adapter';
import {
ParticipantCreateRequest,
AccountCreateRequest,
TransferCreateRequest,
NostroVostroTransfer,
NostroVostroAccount,
} from '@/core/nostro-vostro/nostro-vostro.types';
export class MyCustomAdapter extends BasePluginAdapter {
private apiEndpoint: string;
private apiKey: string;
constructor(config: Record<string, unknown> = {}) {
super('MyCustomAdapter', '1.0.0', config);
this.apiEndpoint = config.apiEndpoint as string;
this.apiKey = config.apiKey as string;
}
async isAvailable(): Promise<boolean> {
// Check connectivity to your system
try {
const response = await fetch(`${this.apiEndpoint}/health`, {
headers: { 'Authorization': `Bearer ${this.apiKey}` }
});
return response.ok;
} catch {
return false;
}
}
// Implement other methods...
}
```
### 2. Implement Mapping Methods
#### Participant Mapping
```typescript
mapParticipant(internalData: unknown): ParticipantCreateRequest {
const customer = internalData as YourInternalCustomer;
return {
participantId: customer.id,
name: customer.name,
bic: customer.bic,
lei: customer.lei,
country: customer.countryCode,
regulatoryTier: this.mapRegulatoryTier(customer.category),
metadata: {
internalId: customer.id,
// Additional metadata
},
};
}
```
#### Account Mapping
```typescript
mapAccount(internalData: unknown): AccountCreateRequest {
const account = internalData as YourInternalAccount;
return {
ownerParticipantId: account.customerId,
counterpartyParticipantId: account.correspondentId,
ibanOrLocalAccount: account.accountNumber,
currency: account.currency,
accountType: account.type === 'NOSTRO' ? 'NOSTRO' : 'VOSTRO',
metadata: {
internalAccountId: account.id,
},
};
}
```
#### Transfer Mapping
```typescript
mapTransfer(internalData: unknown): TransferCreateRequest {
const transaction = internalData as YourInternalTransaction;
return {
fromAccountId: transaction.debitAccount,
toAccountId: transaction.creditAccount,
amount: transaction.amount.toString(),
currency: transaction.currency,
valueDate: transaction.valueDate,
reference: transaction.reference,
metadata: {
internalTransactionId: transaction.id,
},
};
}
```
### 3. Implement Posting Methods
```typescript
async postTransfer(transfer: NostroVostroTransfer): Promise<{success: boolean; internalId?: string; error?: string}> {
try {
const internalTransaction = this.mapTransferToInternal(transfer);
const response = await fetch(`${this.apiEndpoint}/transactions`, {
method: 'POST',
headers: {
'Authorization': `Bearer ${this.apiKey}`,
'Content-Type': 'application/json'
},
body: JSON.stringify(internalTransaction)
});
if (!response.ok) {
throw new Error(`HTTP ${response.status}: ${response.statusText}`);
}
const result = await response.json();
return { success: true, internalId: result.transactionId };
} catch (error) {
return this.handleError(error, 'postTransfer');
}
}
```
### 4. Register Plugin
```typescript
import { pluginRegistry } from '@/integration/plugins/plugin-registry';
import { MyCustomAdapter } from './my-custom-adapter';
// Register during application startup
pluginRegistry.register('my-custom', new MyCustomAdapter({
apiEndpoint: process.env.MY_CUSTOM_API_ENDPOINT,
apiKey: process.env.MY_CUSTOM_API_KEY,
}));
```
## Best Practices
### 1. Error Handling
Always use the base class error handling:
```typescript
try {
// Your code
} catch (error) {
return this.handleError(error, 'methodName');
}
```
### 2. Idempotency
Support idempotency keys in your internal system:
```typescript
mapTransferToInternal(transfer: NostroVostroTransfer): unknown {
return {
transactionId: transfer.transferId,
idempotencyKey: transfer.idempotencyKey, // Pass through
// ... other fields
};
}
```
### 3. Validation
Validate data before mapping:
```typescript
mapTransfer(internalData: unknown): TransferCreateRequest {
const tx = internalData as YourTransaction;
if (!tx.amount || tx.amount <= 0) {
throw new Error('Invalid amount');
}
// Continue mapping...
}
```
### 4. Logging
Log important operations:
```typescript
async postTransfer(transfer: NostroVostroTransfer): Promise<...> {
console.log(`[${this.name}] Posting transfer ${transfer.transferId}`);
// ... implementation
}
```
## Testing
### Unit Tests
```typescript
describe('MyCustomAdapter', () => {
let adapter: MyCustomAdapter;
beforeEach(() => {
adapter = new MyCustomAdapter({
apiEndpoint: 'http://localhost:3000',
apiKey: 'test-key',
});
});
it('should map participant correctly', () => {
const internal = { id: '123', name: 'Test Bank', ... };
const result = adapter.mapParticipant(internal);
expect(result.name).toBe('Test Bank');
});
});
```
### Integration Tests
Test against a sandbox environment of your core banking system.
## Reference Implementations
See existing adapters for examples:
- `temenos-adapter.ts` - Temenos T24 integration
- `flexcube-adapter.ts` - Oracle Flexcube integration
- `swift-adapter.ts` - SWIFT message handling
- `iso20022-adapter.ts` - ISO 20022 message handling

# RTGS System to DBIS Nostro/Vostro API Mapping
## Overview
This document provides patterns for mapping local RTGS (Real-Time Gross Settlement) systems to the DBIS Nostro/Vostro API.
## Common RTGS Patterns
### Pattern 1: REST API Integration
Many modern RTGS systems expose REST APIs:
```typescript
// RTGS API call
const rtgsTransfer = {
fromAccount: "ACC123",
toAccount: "ACC456",
amount: 1000.00,
currency: "USD",
valueDate: "2024-01-15",
reference: "REF123"
};
// Map to DBIS API
const dbisTransfer = {
fromAccountId: rtgsTransfer.fromAccount,
toAccountId: rtgsTransfer.toAccount,
amount: rtgsTransfer.amount.toString(),
currency: rtgsTransfer.currency,
valueDate: rtgsTransfer.valueDate,
reference: rtgsTransfer.reference
};
```
### Pattern 2: Database Integration
For RTGS systems with direct database access:
```sql
-- RTGS Database Query
SELECT
transaction_id,
debit_account,
credit_account,
amount,
currency,
value_date,
reference
FROM rtgs_transactions
WHERE status = 'PENDING';
-- Map to DBIS API request
```
### Pattern 3: Message Queue Integration
For RTGS systems using message queues (Kafka, RabbitMQ, etc.):
```typescript
// Consume from RTGS queue
consumer.on('message', (rtgsMessage) => {
const transfer = mapRtgstoDbis(rtgsMessage);
await nostroVostroService.createTransfer(transfer);
});
```
## Generic RTGS Adapter Template
```typescript
import { BasePluginAdapter } from './generic-adapter';
export class GenericRtgAdapter extends BasePluginAdapter {
constructor(config: Record<string, unknown> = {}) {
super('GenericRTGS', '1.0.0', config);
}
mapTransfer(internalData: unknown): TransferCreateRequest {
const rtgsTx = internalData as {
fromAccount: string;
toAccount: string;
amount: number;
currency: string;
valueDate: string;
reference?: string;
};
return {
fromAccountId: rtgsTx.fromAccount,
toAccountId: rtgsTx.toAccount,
amount: rtgsTx.amount.toString(),
currency: rtgsTx.currency,
valueDate: rtgsTx.valueDate,
reference: rtgsTx.reference,
metadata: {
source: 'RTGS',
rtgsSystem: this.config.rtgsSystemName,
},
};
}
// Implement other methods based on RTGS system capabilities
}
```
## Account Mapping
RTGS accounts typically map directly:
```typescript
mapAccount(internalData: unknown): AccountCreateRequest {
const rtgsAccount = internalData as {
accountNumber: string;
customerId: string;
correspondentId: string;
currency: string;
accountType: 'NOSTRO' | 'VOSTRO';
};
return {
ownerParticipantId: rtgsAccount.customerId,
counterpartyParticipantId: rtgsAccount.correspondentId,
ibanOrLocalAccount: rtgsAccount.accountNumber,
currency: rtgsAccount.currency,
accountType: rtgsAccount.accountType,
};
}
```
## Reconciliation
RTGS reconciliation typically involves:
1. **Statement Comparison**: Compare RTGS statements with DBIS transactions
2. **Balance Matching**: Match opening/closing balances
3. **Transaction Matching**: Match individual transactions by reference
```typescript
async reconcile(accountId: string, asOfDate: Date): Promise<{matched: number; breaks: unknown[]}> {
// Get RTGS statement
const rtgsStatement = await this.getRtgStatement(accountId, asOfDate);
// Get DBIS transactions
const dbisTransactions = await nostroVostroService.listTransfers({
fromAccountId: accountId,
valueDate: asOfDate,
});
// Match transactions
const matched = this.matchTransactions(rtgsStatement, dbisTransactions);
const breaks = this.findBreaks(rtgsStatement, dbisTransactions);
return { matched, breaks };
}
```
## Best Practices
1. **Idempotency**: Use RTGS transaction IDs as idempotency keys
2. **Error Handling**: Map RTGS error codes to DBIS error codes
3. **Retry Logic**: Implement retry for transient RTGS failures
4. **Monitoring**: Monitor RTGS integration health
5. **Audit Trail**: Log all RTGS interactions

# SWIFT MT/MX to DBIS Nostro/Vostro API Mapping
## Overview
This document provides mapping guidance for converting SWIFT messages to DBIS Nostro/Vostro API requests.
## Message Types
### MT103 (Customer Credit Transfer)
**SWIFT Format**:
```
{1:F01BANKUS33AXXX1234567890}
{2:O1031200240115BANKUS33AXXX123456789012345678901234567890}
{3:{108:TRF123}}
{4:
:20:TRF123
:23B:CRED
:32A:240115USD1000,00
:50K:/1234567890
JOHN DOE
:59:/GB82WEST12345698765432
JANE SMITH
:70:PAYMENT REFERENCE
-}
```
**DBIS API Request**:
```json
{
"fromAccountId": "1234567890",
"toAccountId": "GB82WEST12345698765432",
"amount": "1000.00",
"currency": "USD",
"valueDate": "2024-01-15",
"reference": "TRF123",
"metadata": {
"swiftMessageType": "103",
"swiftReference": "TRF123"
}
}
```
### MT202 (General Financial Institution Transfer)
Similar to MT103 but for interbank transfers.
### MX (ISO 20022) Messages
See [ISO 20022 Mapping Guide](./iso20022-mapping.md) for MX message handling.
## Field Mappings
| SWIFT Field | DBIS API Field | Notes |
|-------------|----------------|-------|
| `:20:` | `reference` | Transaction reference |
| `:32A:` (date) | `valueDate` | Value date (YYMMDD format) |
| `:32A:` (currency) | `currency` | Currency code |
| `:32A:` (amount) | `amount` | Transfer amount |
| `:50K:` or `:50A:` | `fromAccountId` | Ordering customer account |
| `:59:` | `toAccountId` | Beneficiary account |
| `:52A:` | `fromParticipantId` | Sender BIC |
| `:56A:` | `toParticipantId` | Receiver BIC |
| `:70:` | `reference` | Remittance information |
## Implementation
Use the `SwiftAdapter` class:
```typescript
import { SwiftAdapter } from '@/integration/plugins/swift-adapter';
const adapter = new SwiftAdapter();
const swiftMessage = adapter.parseSwiftMessage(mt103String);
const transferRequest = adapter.mapTransfer(swiftMessage);
```
## Date Format Conversion
SWIFT uses YYMMDD format, DBIS uses ISO 8601:
```typescript
// SWIFT: 240115
// DBIS: 2024-01-15
```
## Error Handling
SWIFT errors map to DBIS error codes:
| SWIFT Error | DBIS Error Code |
|-------------|-----------------|
| Invalid message format | `VALIDATION_ERROR` |
| Account not found | `NOT_FOUND` |
| Invalid BIC | `VALIDATION_ERROR` |

# Sub-Volume A: Global Atomic Settlements (GAS) Network
## Overview
The Global Atomic Settlements (GAS) Network enables **instant, irreversible, atomic settlement** across multiple financial dimensions:
- Classical financial networks
- CBDC chains
- Commodity token networks
- Security token systems
- Quantum financial rails
- Multiversal DBIS layers
## Architecture
### Multi-Dimensional Atomic Settlement
GAS extends the existing atomic settlement service to support multi-dimensional commit verification:

# Sub-Volume B: Global Reserve Unit (GRU) Integration
## Overview
The Global Reserve Unit (GRU) Integration integrates the GRU monetary system into DBIS' omniversal framework with hierarchical structure and XAU-anchored valuation.
## GRU Hierarchy
### Defined Ratios
- **1 M00 GRU = 5 M0 GRU**
- **1 M00 GRU = 25 M1 GRU**
- **1 M00 GRU = x M0 GRU + y M1 GRU** (mixed composition)
### Unit Types
- **M00**: Base unit (highest tier)
- **M0**: Intermediate unit (1 M00 = 5 M0)
- **M1**: Lowest unit (1 M00 = 25 M1, 1 M0 = 5 M1)
## GRU Asset Valuation
All triangulations occur through **XAU (gold)**, anchoring GRU to:
- **Fiat currencies** (USD, EUR, etc.)
- **Commodities** (Silver, Platinum, Oil, etc.)
- **CBDC** (Central Bank Digital Currencies)
- **Tokenized assets** (Security tokens, etc.)
### Valuation Formula
```
GRU Value = XAU Value × Triangulation Rate
```
Base rate: **1 GRU M00 = 1 oz XAU** (troy ounce)
## GRU Bond Systems
### GRU-Linked Bonds
Two bond types are supported:
- **Li99PpOsB10**: 99-year bond with 10% interest (one-time structure)
- **Li99PpAvB10**: 99-year bond with 10% average interest
### Bond Features
- Principal amount in GRU
- Fixed or variable interest rates
- Coupon payments
- Maturity date calculation
- Automatic redemption at maturity
## GRU Liquidity Loop
### Atomic Transaction Loop
The GRU liquidity loop executes atomic transactions until a target value is reached:
```
7 → 10 GRU → 9.55 (net after FX)
```
**Process**:
1. Start with initial amount (e.g., 7 GRU)
2. Execute atomic transaction via GAS network
3. Apply FX cost (e.g., 4.5%)
4. Calculate net value (e.g., 9.55)
5. Re-run until target value reached or max iterations
### Loop Parameters

# GRU Bond Pricing Models
## Overview
GRU bond pricing models provide comprehensive valuation frameworks accounting for perpetual bond structures, index adjustments, and multi-reality settlement considerations.
## Base Pricing Model
### Formula
```
Price = PV(Coupons) + PV(Perpetual Component) + Index Adjustment(LiXAU/LiPMG/etc.)
```
### Components
#### Present Value of Coupons
```
PV(Coupons) = Σ(Coupon[i] / (1 + r)^t[i])
```
Where:
- `Coupon[i]` = Coupon payment at period i
- `r` = Discount rate
- `t[i]` = Time to coupon payment i
#### Present Value of Perpetual Component
```
PV(Perpetual) = Principal / r
```
For perpetual bonds, the principal value is discounted at the required rate of return.
#### Index Adjustment
```
Index Adjustment = Principal × (IndexValue / BaseIndexValue - 1) × IndexWeight
```
Where:
- `IndexValue` = Current index value (LiXAU, LiPMG, etc.)
- `BaseIndexValue` = Index value at bond issuance
- `IndexWeight` = Weight of index in bond pricing
## Discounted Acquisition Model
### Formula
```
Acquisition Price = Nominal / 0.15
```
### Purpose
Used for reserve expansion and sovereign acquisition of GRU bonds.
### Characteristics
- High discount (85% off nominal)
- Reserve expansion mechanism
- Sovereign access pricing
- Long-term holding incentive
## GRU Liquidity Loop-Linked Yield
### Formula
```
Yield = f(7→10→9.55 cycles, Index Volatility, Sovereign Risk)
```
### Components
#### Liquidity Loop Cycles
The 7→10→9.55 cycle represents:
- Initial capital: 7 GRU
- Quantum mint: 10 GRU
- FX/spread deduction: 9.55 GRU
- Reinjection into next cycle
#### Index Volatility
```
Index Volatility = σ(IndexReturns) × VolatilityWeight
```
#### Sovereign Risk
```
Sovereign Risk = SRI_Score × RiskWeight
```
### Yield Calculation
```
Yield = BaseYield + LoopAdjustment + VolatilityAdjustment - RiskPenalty
```
Where:
- `BaseYield` = Base GRU bond yield
- `LoopAdjustment` = f(cycle efficiency, loop iterations)
- `VolatilityAdjustment` = Index volatility impact
- `RiskPenalty` = Sovereign risk premium
## Index-Linked Pricing
### LiXAU (Gold Index)
```
Price Adjustment = Principal × (XAU_Price / XAU_Base) × XAU_Weight
```
### LiPMG (PGM Basket Index)
```
Price Adjustment = Principal × (PGM_Index / PGM_Base) × PGM_Weight
```
### LiBMG (BMG Basket Indices)
```
Price Adjustment = Principal × Σ(BMG[i]_Weight × (BMG[i]_Price / BMG[i]_Base))
```
## Perpetual Bond Specific Pricing
### Perpetual Component Valuation
For 99-year perpetual bonds:
```
Perpetual Value = Annual Coupon / Required Yield
```
### Buy-Back Option Pricing
For 10-year buy-back option:
```
Option Value = PV(Principal at Buy-Back) - PV(Coupons Lost)
```
## Multi-Reality Pricing
### Quantum State Pricing
```
Price_Quantum = Σ(Probability[i] × Price[i])
```
### Parallel Reality Pricing
```
Price_Parallel = Average(Price[Reality[i]])
```
### Holographic Pricing
```
Price_Holographic = Project(Price_Classical, Holographic_Field)
```
### Merged Pricing
```
Price_Merged = Merge(Price_Classical, Price_Quantum, Price_Parallel, Price_Holographic)
```
## Pricing Service Integration
### Real-Time Pricing
- Continuous price updates
- Index value feeds
- Market data integration
- Automated recalculation
### Historical Pricing
- Price history tracking
- Performance analytics
- Volatility calculations
- Risk metrics

# DBIS Expansion Volume V: Global Identity Graph, Sovereign AI Risk Engine, CBDC Tokenomics, Arbitration Statutes, and Meta-Ledger Synchronization
This volume establishes the advanced intelligence, identity, legal, and meta-ledger systems required for DBIS to operate as a fully autonomous global settlement, risk, and compliance authority.
## Overview
Volume V introduces five major systems:
1. **Global Banking Identity Graph (GBIG)** - Unified digital identity system
2. **Sovereign AI Risk Engine (SARE)** - Predictive risk analysis across the ecosystem
3. **Global CBDC Tokenomics Framework (GCTF)** - Economic and issuance parameters for CBDCs
4. **DBIS International Arbitration Statutes (DIAS)** - Cross-border financial dispute resolution
5. **Meta-Ledger System (MLS)** - Synchronization of all DBIS global datasets
---
## 1. Global Banking Identity Graph (GBIG)
### Purpose
The Global Banking Identity Graph (GBIG) is DBIS' unified digital identity system mapping:
- Sovereign Central Banks (SCBs)
- Private banks
- CBDC wallets (retail, wholesale, institutional)
- Smart contracts
- Nodes, validators, APIs, and operational actors
GBIG ensures:
- Global KYC/KYB coherence
- Sovereign cross-verification
- Anti-fraud intelligence
- Multi-layer identity trust scoring
### Identity Layers
#### Layer 1 – Sovereign Identity Layer (SIL)
- Root sovereign certificates
- SCB master keys
- HSM-backed validation signatures
#### Layer 2 – Institutional Identity Layer (IIL)
- Private bank identities
- API credential certificates
- CBDC institutional wallet identities
#### Layer 3 – Retail & Individual Layer (RIL)
- Retail CBDC wallets
- Device-bound identities
- Zero-knowledge KYC proofs
#### Layer 4 – Contract Identity Layer (CIL)
- Every smart contract holds:
- Contract hash ID
- Sovereign signatory list
- Execution permissions
### Identity Trust Scoring (ITS)
Every entity receives a dynamic trust score:
```
ITS = base_trust + (KYC_level * 10) + behavior_score - risk_penalties
```
Factors include:
- Transaction history
- AML flags
- FX risk exposure
- Device security posture
### API Endpoints

## 2. Sovereign AI Risk Engine (SARE)
### Purpose
SARE predicts sovereign, market, and systemic risks across the DBIS ecosystem. It is composed of four AI subsystems:
- **Liquidity Shock Analyzer (LSA)** - Analyzes liquidity risks
- **FX Collapse Predictor (FXCP)** - Predicts FX volatility shocks
- **CBDC Network Health Engine (CNHE)** - Monitors CBDC network health
- **Commodity Stress Model (CSM)** - Forecasts commodity reserve depletion
### Data Inputs
- Daily sovereign liquidity reports
- Cross-border flow graphs
- FX volatility surfaces
- CBDC behavior metrics
- Commodity reserve readings
- Trade finance exposure
- Smart contract execution patterns
### AI Risk Outputs
1. **Sovereign Stress Score (SSS)** - 0–100 scale, predictive of sovereign failure
2. **FX Shock Probability (FXSP)** - Probability of a 10%+ volatility movement
3. **CBDC Liquidity Tension Index (CLTI)** - Signals liquidity strain in CBDC flows
4. **Commodity Depletion Alert (CDA)** - Forecasts depletion of backing reserves
### System Actions

# Autonomous Liquidity Provision System (ALPS)
## Overview
ALPS is the autonomous liquidity engine of DBIS, providing real-time liquidity injections without human intervention. It includes real-time liquidity monitoring, predictive stress module, automated stabilization executor, and GLP interface.
## Architecture
ALPS includes:
- **Real-time liquidity monitor**: Monitors SXLR (Sovereign Liquidity Ratio) for all sovereigns
- **Predictive stress module**: Predicts liquidity stress events
- **Automated stabilization executor**: Executes injections/withdrawals automatically
- **GLP interface**: Integrates with Global Liquidity Pool
## Liquidity Injection Algorithm
```
if (liquidity_ratio < threshold)
amount = required_liquidity - current_liquidity
inject(amount)
```
Inputs:
- SXLR (Sovereign Liquidity Ratio)
- SRI risk levels
- FX volatility indices
- CBDC flow constraints
## Autonomous Liquidity Withdrawal
Reverse mechanism triggers when:
- Excess liquidity → inflation risk
- Settlement congestion decreases
- FX bands stabilize
## API Endpoints
### Run Autonomous Engine
```http
POST /api/v1/alps/run
```
### Monitor Liquidity
```http
GET /api/v1/alps/monitor
GET /api/v1/alps/monitor/:sovereignBankId
```
### Predict Stress Events
```http
POST /api/v1/alps/stress/predict
GET /api/v1/alps/stress?sovereignBankId=xxx
```
### Get Actions
```http
GET /api/v1/alps/actions?sovereignBankId=xxx&actionType=INJECTION
```
### Manual Injection/Withdrawal
```http
POST /api/v1/alps/inject
POST /api/v1/alps/withdraw
```
## Usage Example
```typescript
import { alpsService } from '@/core/treasury/alps';
// Run autonomous engine
await alpsService.runAutonomousEngine();
// Monitor liquidity
const ratios = await alpsService.monitorLiquidity();
// Predict stress events
const events = await alpsService.predictStressEvents();
```
## Database Models
- `AutonomousLiquidityAction`: Injection/withdrawal records
- `LiquidityStressEvent`: Predicted stress events
- `SovereignLiquidityRatio`: SXLR tracking

# Global AML & Sanctions Engine (GASE)
## Overview
GASE is the global AML and sanctions engine providing sovereign sanctions list synchronization, automated risk tiering of transactions, PEP graph linking, and Suspicious Activity Score (SAS) calculation.
## Core Functions
- **Sovereign Sanctions List Synchronization**: Unified sanctions list from OFAC, EU, UN, etc.
- **Automated Risk Tiering**: Assign risk tiers (TIER_1 to TIER_4) to entities
- **PEP Graph Linking**: Graph structure for Politically Exposed Persons and relationships
- **Suspicious Activity Score (SAS)**: Multi-factor risk scoring for transactions
## Sanctions Matching Logic
```
if fuzzy_match(entity.name, sanctions_list) > 0.93:
block_transaction()
```
## API Endpoints
### Synchronize Sanctions
```http
POST /api/v1/gase/sanctions/sync
```
### Search Sanctions
```http
POST /api/v1/gase/sanctions/search
```
### Add PEP
```http
POST /api/v1/gase/pep/add
```
### Find PEP Connections
```http
GET /api/v1/gase/pep/:entityId/connections?maxDepth=2
```
### Calculate SAS
```http
POST /api/v1/gase/sas/calculate
GET /api/v1/gase/sas/:transactionId
```
### Risk Tiering
```http
GET /api/v1/gase/risk-tier/:entityId
POST /api/v1/gase/risk-tier/:entityId/assign
```
## Usage Example
```typescript
import { gaseService } from '@/core/compliance/gase';
// Synchronize sanctions lists
await gaseService.syncSanctionsLists();
// Search sanctions
const matches = await gaseService.searchSanctions('entity-name', 0.93);
// Calculate SAS
const sas = await gaseService.calculateSAS(transactionId, entityId);
// Assign risk tier
const riskTier = await gaseService.assignRiskTier(entityId);
```
## Database Models
- `GlobalSanctionsList`: Unified sanctions list
- `PEPGraphNode`: PEP graph nodes
- `PEPGraphEdge`: PEP relationships
- `SuspiciousActivityScore`: SAS calculations
- `RiskTier`: Risk tier assignments
