# Architecture Documentation
## System Overview
Strategic is a TypeScript CLI + Solidity atomic executor for DeFi strategies. It enables users to define complex multi-step DeFi operations in JSON and execute them atomically on-chain.
## Execution Flow
```
Strategy JSON
Strategy Loader (validate, substitute blinds)
Planner/Compiler (compile steps → calls)
Guard Evaluation (pre-execution checks)
Execution Engine
├─ Simulation Mode (fork testing)
├─ Dry Run (validation only)
├─ Explain Mode (show plan)
└─ Live Execution
├─ Direct (via executor contract)
└─ Flashbots (MEV protection)
```
## Flash Loan Flow
```
1. Strategy defines aaveV3.flashLoan step
2. Compiler detects flash loan requirement
3. Steps after flash loan are compiled as callback operations
4. Executor.executeFlashLoan() is called
5. Aave Pool calls executeOperation() callback
6. Callback operations execute atomically
7. Flash loan is repaid automatically
```
## Guard Evaluation Order
1. **Global Guards** (strategy-level)
- Evaluated before compilation
- If any guard with `onFailure: "revert"` fails, execution stops
2. **Step Guards** (per-step)
- Evaluated before each step execution
- Can be `revert`, `warn`, or `skip`
3. **Post-Execution Guards**
- Evaluated after execution completes
- Used for validation (e.g., health factor check)
## Component Architecture
### Core Components
- **CLI** (`src/cli.ts`): User interface, command parsing
- **Strategy Loader** (`src/strategy.ts`): JSON parsing, validation, blind substitution
- **Planner/Compiler** (`src/planner/compiler.ts`): Step → call compilation
- **Guard Engine** (`src/planner/guards.ts`): Safety check evaluation
- **Execution Engine** (`src/engine.ts`): Orchestrates execution
- **AtomicExecutor.sol**: On-chain executor contract
### Adapters
Protocol-specific adapters abstract contract interactions:
- Each adapter provides typed methods
- Handles ABI encoding/decoding
- Manages protocol-specific logic
### Guards
Safety checks that can block execution:
- `oracleSanity`: Price validation
- `twapSanity`: TWAP price checks
- `maxGas`: Gas limits
- `minHealthFactor`: Aave health factor
- `slippage`: Slippage protection
- `positionDeltaLimit`: Position size limits
## Data Flow
1. **Strategy Definition**: JSON file with steps, guards, blinds
2. **Blind Substitution**: Runtime values replace `{{blind}}` placeholders
3. **Compilation**: Steps → contract calls (calldata)
4. **Guard Evaluation**: Safety checks before execution
5. **Execution**: Calls sent to executor contract
6. **Telemetry**: Results logged (opt-in)
## Security Model
- **Allow-List**: Executor only calls allow-listed contracts
- **Pausability**: Owner can pause executor
- **Flash Loan Security**: Only authorized pools can call callback
- **Guard Enforcement**: Guards can block unsafe operations
- **Reentrancy Protection**: Executor uses ReentrancyGuard
## Cross-Chain Architecture
For cross-chain strategies:
1. Source chain executes initial steps
2. Bridge message sent (CCIP/LayerZero/Wormhole)
3. Target chain receives message
4. Compensating leg executes if main leg fails
5. State guards monitor message delivery
## Testing Strategy
- **Unit Tests**: Individual components (adapters, guards, compiler)
- **Integration Tests**: End-to-end strategy execution
- **Foundry Tests**: Solidity contract testing
- **Fork Simulation**: Test on mainnet fork before live execution

# Strategic - TypeScript CLI + Solidity Atomic Executor
**Status**: ✅ **Active**
**Purpose**: A full-stack TypeScript CLI scaffold with Solidity atomic executor for executing complex DeFi strategies atomically. Enables users to define multi-step DeFi operations in JSON and execute them atomically on-chain with comprehensive safety guards.
## 🎯 Overview
Strategic is a DeFi strategy execution framework that allows developers and traders to:
- **Define complex strategies** in a simple JSON DSL
- **Execute atomically** across multiple DeFi protocols in a single transaction
- **Ensure safety** with built-in guards (oracle checks, slippage protection, health factor monitoring)
- **Simulate before execution** using fork testing and dry-run modes
- **Protect against MEV** with Flashbots integration
**Use Cases**:
- Leveraged yield farming strategies
- Arbitrage opportunities across protocols
- Debt refinancing and position optimization
- Multi-protocol flash loan strategies
- Risk-managed DeFi operations
## Features
- **Strategy JSON DSL** with blinds (sealed runtime params), guards, and steps
- **Protocol Adapters**: Aave v3, Compound v3, Uniswap v3, MakerDAO, Balancer, Curve, 1inch/0x, Lido, GMX
- **Atomic Execution**: Single-chain atomic calls via multicall or flash loan callback
- **Safety Guards**: Oracle sanity, TWAP sanity, max gas, min health factor, slippage, position limits
- **Flashbots Integration**: MEV-synchronized multi-wallet coordination
- **Fork Simulation**: Anvil/Tenderly fork simulation with state snapshots
- **Cross-Chain Support**: Orchestrator for CCIP/LayerZero/Wormhole (placeholder)
- **Multi-Chain**: Mainnet, Arbitrum, Optimism, Base
## Installation
```bash
pnpm install
pnpm build
```
## Setup
1. Copy environment template:
```bash
cp .env.example .env
```
2. Fill in your RPC endpoints and private key:
```env
RPC_MAINNET=https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
PRIVATE_KEY=your_private_key_here
```
3. Deploy the executor (Foundry):
```bash
forge script script/Deploy.s.sol --rpc-url $RPC_MAINNET --broadcast
```
4. Update `EXECUTOR_ADDR` in `.env`
## Usage
### Run a strategy
```bash
# Simulate execution
pnpm start run strategies/sample.recursive.json --simulate
# Dry run (validate only)
pnpm start run strategies/sample.recursive.json --dry
# Explain strategy
pnpm start run strategies/sample.recursive.json --explain
# Fork simulation
pnpm start run strategies/sample.recursive.json --simulate --fork $RPC_MAINNET --block 18000000
```
### Validate a strategy
```bash
pnpm start validate strategies/sample.recursive.json
```
## Strategy DSL
Strategies are defined in JSON with the following structure:
```json
{
"name": "Strategy Name",
"chain": "mainnet",
"executor": "0x...",
"blinds": [
{
"name": "amount",
"type": "uint256",
"description": "Amount to use"
}
],
"guards": [
{
"type": "minHealthFactor",
"params": { "minHF": 1.2, "user": "0x..." },
"onFailure": "revert"
}
],
"steps": [
{
"id": "step1",
"action": {
"type": "aaveV3.supply",
"asset": "0x...",
"amount": "{{amount}}"
}
}
]
}
```
## Architecture
- **CLI** (`src/cli.ts`): Commander-based CLI with prompts
- **Strategy Loader** (`src/strategy.ts`): Loads and validates strategy JSON
- **Planner/Compiler** (`src/planner/compiler.ts`): Bundles steps into atomic calls
- **Guards** (`src/guards/`): Safety checks (oracle, slippage, HF, etc.)
- **Adapters** (`src/adapters/`): Protocol integrations
- **Executor** (`contracts/AtomicExecutor.sol`): Solidity contract for atomic execution
- **Engine** (`src/engine.ts`): Execution engine with simulation support
## Protocol Adapters
- **Aave v3**: supply, withdraw, borrow, repay, flash loan, EMode, collateral
- **Compound v3**: supply, withdraw, borrow, repay, allow, liquidity
- **Uniswap v3**: exact input/output swaps, multi-hop, TWAP
- **MakerDAO**: vault ops (open, frob, join, exit)
- **Balancer V2**: swaps, batch swaps
- **Curve**: exchange, exchange_underlying, pool registry
- **1inch/0x**: RFQ integration
- **Lido**: stETH/wstETH wrap/unwrap
- **GMX**: perps position management
## Guards
- `oracleSanity`: Chainlink oracle price checks
- `twapSanity`: Uniswap TWAP validation
- `maxGas`: Gas limit/price ceilings
- `minHealthFactor`: Aave health factor minimum
- `slippage`: Slippage protection
- `positionDeltaLimit`: Position size limits
## Development
```bash
# Run tests
pnpm test
# Lint
pnpm lint
# Format
pnpm format
```

uint256 premium = loanAmount / 1000; // 0.1%
uint256 requiredRepayment = loanAmount + premium;
// Don't mint enough for repayment
token.mint(address(executor), loanAmount); // Not enough!
bytes memory params = abi.encode(new address[](0), new bytes[](0));

# Deployment Guide
## Prerequisites
- Node.js 18+
- pnpm 8+
- Foundry (for contract deployment)
- RPC endpoints for target chains
- Private key or hardware wallet
## Step 1: Environment Setup
1. Clone the repository:
```bash
git clone <repo-url>
cd strategic
```
2. Install dependencies:
```bash
pnpm install
```
3. Copy environment template:
```bash
cp .env.example .env
```
4. Configure `.env`:
```bash
# RPC Endpoints
RPC_MAINNET=https://eth-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_ARBITRUM=https://arb-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_OPTIMISM=https://opt-mainnet.g.alchemy.com/v2/YOUR_KEY
RPC_BASE=https://base-mainnet.g.alchemy.com/v2/YOUR_KEY
# Private Key (use hardware wallet in production)
PRIVATE_KEY=0x...
# Executor Address (set after deployment)
EXECUTOR_ADDR=
# Optional: 1inch API Key
ONEINCH_API_KEY=
# Optional: Flashbots
FLASHBOTS_RELAY=https://relay.flashbots.net
```
## Step 2: Build
```bash
pnpm build
```
## Step 3: Deploy Executor Contract
### Testnet Deployment
1. Set up Foundry:
```bash
forge install
```
2. Deploy to testnet:
```bash
forge script script/Deploy.s.sol \
--rpc-url $RPC_SEPOLIA \
--broadcast \
--verify
```
3. Update `.env` with deployed address:
```bash
EXECUTOR_ADDR=0x...
```
### Mainnet Deployment
1. **Verify addresses** in `scripts/Deploy.s.sol` match your target chain
2. Deploy with multi-sig:
```bash
forge script script/Deploy.s.sol \
--rpc-url $RPC_MAINNET \
--broadcast \
--verify \
--sender <MULTISIG_ADDRESS>
```
3. **Transfer ownership** to multi-sig after deployment
4. **Configure allow-list** via multi-sig:
```solidity
executor.setAllowedTargets([...protocols], true);
executor.setAllowedPool(aavePool, true);
```
## Step 4: Verify Deployment
1. Check contract on block explorer
2. Verify ownership
3. Verify allow-list configuration
4. Test with small transaction
## Step 5: Test Strategy
1. Create test strategy:
```json
{
"name": "Test",
"chain": "mainnet",
"executor": "0x...",
"steps": [
{
"id": "test",
"action": {
"type": "aaveV3.supply",
"asset": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
"amount": "1000000"
}
}
]
}
```
2. Simulate first:
```bash
strategic run test.json --simulate --fork $RPC_MAINNET
```
3. Dry run:
```bash
strategic run test.json --dry
```
4. Execute with small amount:
```bash
strategic run test.json
```
## Step 6: Production Configuration
### Multi-Sig Setup
1. Create multi-sig wallet (Gnosis Safe recommended)
2. Transfer executor ownership to multi-sig
3. Configure signers (minimum 3-of-5)
4. Set up emergency pause procedures
### Monitoring
1. Set up transaction monitoring
2. Configure alerts (see PRODUCTION_RECOMMENDATIONS.md)
3. Set up health dashboard
4. Configure logging
### Security
1. Review access controls
2. Test emergency pause
3. Verify allow-list
4. Set up incident response plan
## Troubleshooting
### Deployment Fails
- Check RPC endpoint
- Verify gas prices
- Check contract size limits
- Verify addresses are correct
### Execution Fails
- Check executor address in strategy
- Verify allow-list includes target protocols
- Check gas limits
- Verify strategy JSON is valid
### High Gas Usage
- Optimize batch size
- Review strategy complexity
- Consider splitting into multiple transactions
## Post-Deployment
1. Monitor for 24-48 hours
2. Review all transactions
3. Gradually increase limits
4. Expand allow-list as needed
5. Document learnings
## Rollback Plan
If issues occur:
1. Pause executor immediately
2. Review recent transactions
3. Revoke problematic addresses
4. Fix issues
5. Resume with caution

# Guard Development Guide
## Overview
Guards are safety checks that prevent unsafe strategy execution. This guide explains how to create custom guards.
## Guard Structure
A guard consists of:
1. Schema definition (in `strategy.schema.ts`)
2. Evaluation function (in `src/guards/`)
3. Integration (in `src/planner/guards.ts`)
## Creating a Guard
### 1. Define Guard Schema
Add to `src/strategy.schema.ts`:
```typescript
// Add to GuardSchema type enum
"customGuard",
// Guard params are defined in the guard evaluation function
```
### 2. Create Guard File
Create `src/guards/customGuard.ts`:
```typescript
import { Guard } from "../strategy.schema.js";
export interface CustomGuardParams {
threshold: string;
// Add guard-specific parameters
}
/**
* Evaluate custom guard
*
* @param guard - Guard definition
* @param context - Execution context
* @returns Guard evaluation result
*/
export function evaluateCustomGuard(
guard: Guard,
context: {
// Add context properties needed for evaluation
[key: string]: any;
}
): { passed: boolean; reason?: string; [key: string]: any } {
const params = guard.params as CustomGuardParams;
const threshold = BigInt(params.threshold);
// Perform check
const value = context.value || 0n;
const passed = value <= threshold;
return {
passed,
reason: passed ? undefined : `Value ${value} exceeds threshold ${threshold}`,
value,
threshold,
};
}
```
### 3. Integrate Guard
Add to `src/planner/guards.ts`:
```typescript
import { evaluateCustomGuard } from "../guards/customGuard.js";
// Add case in evaluateGuard function
case "customGuard":
result = evaluateCustomGuard(guard, context);
break;
```
## Guard Context
The context object provides access to:
- `oracle`: PriceOracle instance
- `aave`: AaveV3Adapter instance
- `uniswap`: UniswapV3Adapter instance
- `gasEstimate`: GasEstimate
- `chainName`: Chain name
- Custom properties from execution context
## Guard Failure Actions
Guards support three failure actions:
- `revert`: Stop execution (default)
- `warn`: Log warning but continue
- `skip`: Skip the step
## Examples
### Existing Guards
- `oracleSanity.ts`: Price validation
- `twapSanity.ts`: TWAP price checks
- `maxGas.ts`: Gas limits
- `minHealthFactor.ts`: Health factor checks
- `slippage.ts`: Slippage protection
- `positionDeltaLimit.ts`: Position size limits
## Best Practices
1. **Clear Error Messages**: Provide actionable error messages
2. **Context Validation**: Check required context properties
3. **Thresholds**: Use configurable thresholds
4. **Documentation**: Document all parameters
5. **Testing**: Write comprehensive tests
## Testing
Create test file `tests/unit/guards/customGuard.test.ts`:
```typescript
import { describe, it, expect } from "vitest";
import { evaluateCustomGuard } from "../../../src/guards/customGuard.js";
import { Guard } from "../../../src/strategy.schema.js";
describe("Custom Guard", () => {
it("should pass when value is within threshold", () => {
const guard: Guard = {
type: "customGuard",
params: {
threshold: "1000000",
},
};
const context = {
value: 500000n,
};
const result = evaluateCustomGuard(guard, context);
expect(result.passed).toBe(true);
});
});
```

# Performance Tuning Guide
## Overview
This guide covers optimization strategies for improving gas efficiency and execution speed.
## Gas Optimization
### 1. Batch Size Optimization
**Problem**: Large batches consume more gas
**Solution**:
- Optimize batch sizes (typically 5-10 calls)
- Split very large strategies into multiple transactions
- Use flash loans to reduce intermediate steps
### 2. Call Optimization
**Problem**: Redundant or inefficient calls
**Solution**:
- Combine similar operations
- Remove unnecessary calls
- Use protocol-specific batch functions (e.g., Balancer batchSwap)
### 3. Storage Optimization
**Problem**: Excessive storage operations
**Solution**:
- Minimize state changes
- Use events instead of storage where possible
- Cache values when appropriate
## RPC Optimization
### 1. Connection Pooling
**Problem**: Slow RPC responses
**Solution**:
- Use multiple RPC providers
- Implement connection pooling
- Cache non-critical data
### 2. Batch RPC Calls
**Problem**: Multiple sequential RPC calls
**Solution**:
- Use `eth_call` batch requests
- Parallelize independent calls
- Cache results with TTL
### 3. Provider Selection
**Problem**: Single point of failure
**Solution**:
- Use multiple providers
- Implement failover logic
- Monitor provider health
## Caching Strategy
### 1. Price Data Caching
```typescript
// Cache prices with 60s TTL
const priceCache = new Map<string, { price: bigint; timestamp: number }>();
async function getCachedPrice(token: string): Promise<bigint> {
const cached = priceCache.get(token);
if (cached && Date.now() - cached.timestamp < 60000) {
return cached.price;
}
const price = await fetchPrice(token);
priceCache.set(token, { price, timestamp: Date.now() });
return price;
}
```
### 2. Address Caching
```typescript
// Cache protocol addresses (rarely change)
const addressCache = new Map<string, string>();
```
### 3. Gas Estimate Caching
```typescript
// Cache gas estimates with short TTL (10s)
const gasCache = new Map<string, { estimate: bigint; timestamp: number }>();
```
## Strategy Optimization
### 1. Reduce Steps
**Problem**: Too many steps increase gas
**Solution**:
- Combine operations where possible
- Use protocol batch functions
- Eliminate unnecessary steps
### 2. Optimize Flash Loans
**Problem**: Flash loan overhead
**Solution**:
- Only use flash loans when necessary
- Minimize operations in callback
- Optimize repayment logic
### 3. Guard Optimization
**Problem**: Expensive guard evaluations
**Solution**:
- Cache guard results when possible
- Use cheaper guards first
- Skip guards for trusted strategies
## Monitoring Performance
### Metrics to Track
1. **Gas Usage**: Average gas per execution
2. **Execution Time**: Time to complete strategy
3. **RPC Latency**: Response times
4. **Cache Hit Rate**: Caching effectiveness
5. **Success Rate**: Execution success percentage
### Tools
- Gas tracker dashboard
- RPC latency monitoring
- Cache hit rate tracking
- Performance profiling
## Best Practices
1. **Profile First**: Measure before optimizing
2. **Optimize Hot Paths**: Focus on frequently used code
3. **Test Changes**: Verify optimizations don't break functionality
4. **Monitor Impact**: Track improvements
5. **Document Changes**: Keep optimization notes
## Common Optimizations
### Before
```typescript
// Multiple sequential calls
const price1 = await oracle.getPrice(token1);
const price2 = await oracle.getPrice(token2);
const price3 = await oracle.getPrice(token3);
```
### After
```typescript
// Parallel calls
const [price1, price2, price3] = await Promise.all([
oracle.getPrice(token1),
oracle.getPrice(token2),
oracle.getPrice(token3),
]);
```
## Performance Checklist
- [ ] Optimize batch sizes
- [ ] Implement caching
- [ ] Use connection pooling
- [ ] Parallelize independent calls
- [ ] Monitor gas usage
- [ ] Profile execution time
- [ ] Optimize hot paths
- [ ] Document optimizations

# Protocol Integration Guide
## Overview
This guide explains how to add support for new DeFi protocols to the Strategic executor.
## Integration Steps
### 1. Create Adapter
Create a new adapter file in `src/adapters/`:
```typescript
// src/adapters/newProtocol.ts
import { Contract, JsonRpcProvider, Wallet } from "ethers";
import { getChainConfig } from "../config/chains.js";
const PROTOCOL_ABI = [
"function deposit(uint256 amount) external",
// Add required ABI functions
];
export class NewProtocolAdapter {
private contract: Contract;
private provider: JsonRpcProvider;
private signer?: Wallet;
constructor(chainName: string, signer?: Wallet) {
const config = getChainConfig(chainName);
this.provider = new JsonRpcProvider(config.rpcUrl);
this.signer = signer;
this.contract = new Contract(
config.protocols.newProtocol?.address,
PROTOCOL_ABI,
signer || this.provider
);
}
async deposit(amount: bigint): Promise<string> {
if (!this.signer) {
throw new Error("Signer required");
}
const tx = await this.contract.deposit(amount);
return tx.hash;
}
}
```
### 2. Add to Chain Config
Update `src/config/chains.ts`:
```typescript
protocols: {
// ... existing protocols
newProtocol: {
address: "0x...",
},
}
```
### 3. Add to Schema
Update `src/strategy.schema.ts`:
```typescript
z.object({
type: z.literal("newProtocol.deposit"),
amount: z.union([z.string(), z.object({ blind: z.string() })]),
}),
```
### 4. Add to Compiler
Update `src/planner/compiler.ts`:
```typescript
// Import adapter
import { NewProtocolAdapter } from "../adapters/newProtocol.js";
// Add to class
private newProtocol?: NewProtocolAdapter;
// Initialize in constructor
if (config.protocols.newProtocol) {
this.newProtocol = new NewProtocolAdapter(chainName);
}
// Add case in compileStep
case "newProtocol.deposit": {
if (!this.newProtocol) throw new Error("NewProtocol adapter not available");
const action = step.action as Extract<StepAction, { type: "newProtocol.deposit" }>;
const amount = BigInt(action.amount);
const iface = this.newProtocol["contract"].interface;
const data = iface.encodeFunctionData("deposit", [amount]);
calls.push({
to: getChainConfig(this.chainName).protocols.newProtocol!.address,
data,
description: `NewProtocol deposit ${amount}`,
});
break;
}
```
### 5. Add Tests
Create test file `tests/unit/adapters/newProtocol.test.ts`:
```typescript
import { describe, it, expect } from "vitest";
import { NewProtocolAdapter } from "../../../src/adapters/newProtocol.js";
describe("NewProtocol Adapter", () => {
it("should deposit", async () => {
// Test implementation
});
});
```
## Best Practices
1. **Error Handling**: Always validate inputs and handle errors gracefully
2. **Event Parsing**: Parse events for return values when possible
3. **Gas Estimation**: Provide accurate gas estimates
4. **Documentation**: Document all methods and parameters
5. **Testing**: Write comprehensive tests
## Example: Complete Integration
See existing adapters like `src/adapters/aaveV3.ts` for complete examples.

- Document pause/unpause process
## Strategy Security
### Input Validation
1. **Blind Values**: Never hardcode sensitive values
- Use blinds for amounts, addresses
- Validate blind values before use
- Sanitize user inputs
2. **Address Validation**:
- Verify all addresses are valid
- Check addresses match target chain
- Validate protocol addresses
3. **Amount Validation**:
- Check for zero amounts
- Verify amount precision
- Validate against limits
### Guard Usage
1. **Always Use Guards**:

# Strategy Authoring Guide
## Overview
This guide explains how to create and author DeFi strategies using the Strategic executor system.
## Strategy Structure
A strategy is a JSON file that defines a sequence of DeFi operations to execute atomically.
### Basic Structure
```json
{
"name": "Strategy Name",
"description": "What this strategy does",
"chain": "mainnet",
"executor": "0x...",
"blinds": [],
"guards": [],
"steps": []
}
```
## Components
### 1. Strategy Metadata
- **name**: Unique identifier for the strategy
- **description**: Human-readable description
- **chain**: Target blockchain (mainnet, arbitrum, optimism, base)
- **executor**: Optional executor contract address (can be set via env)
### 2. Blinds (Sealed Runtime Parameters)
Blinds are values that are substituted at runtime, not stored in the strategy file.
```json
{
"blinds": [
{
"name": "amount",
"type": "uint256",
"description": "Amount to supply"
}
]
}
```
Use blinds in steps:
```json
{
"amount": { "blind": "amount" }
}
```
### 3. Guards (Safety Checks)
Guards prevent unsafe execution:
```json
{
"guards": [
{
"type": "minHealthFactor",
"params": {
"minHF": 1.2,
"user": "0x..."
},
"onFailure": "revert"
}
]
}
```
**Guard Types**:
- `oracleSanity`: Price validation
- `twapSanity`: TWAP price checks
- `maxGas`: Gas limits
- `minHealthFactor`: Aave health factor
- `slippage`: Slippage protection
- `positionDeltaLimit`: Position size limits
**onFailure Options**:
- `revert`: Stop execution (default)
- `warn`: Log warning but continue
- `skip`: Skip the step
### 4. Steps (Operations)
Steps define the actual DeFi operations:
```json
{
"steps": [
{
"id": "step1",
"description": "Supply to Aave",
"guards": [],
"action": {
"type": "aaveV3.supply",
"asset": "0x...",
"amount": "1000000"
}
}
]
}
```
## Action Types
### Aave v3
```json
{
"type": "aaveV3.supply",
"asset": "0x...",
"amount": "1000000",
"onBehalfOf": "0x..." // optional
}
```
```json
{
"type": "aaveV3.withdraw",
"asset": "0x...",
"amount": "1000000",
"to": "0x..." // optional
}
```
```json
{
"type": "aaveV3.borrow",
"asset": "0x...",
"amount": "1000000",
"interestRateMode": "variable", // or "stable"
"onBehalfOf": "0x..." // optional
}
```
```json
{
"type": "aaveV3.repay",
"asset": "0x...",
"amount": "1000000",
"rateMode": "variable",
"onBehalfOf": "0x..." // optional
}
```
```json
{
"type": "aaveV3.flashLoan",
"assets": ["0x..."],
"amounts": ["1000000"],
"modes": [0] // optional
}
```
### Uniswap v3
```json
{
"type": "uniswapV3.swap",
"tokenIn": "0x...",
"tokenOut": "0x...",
"fee": 3000,
"amountIn": "1000000",
"amountOutMinimum": "990000", // optional
"exactInput": true
}
```
### Compound v3
```json
{
"type": "compoundV3.supply",
"asset": "0x...",
"amount": "1000000",
"dst": "0x..." // optional
}
```
### MakerDAO
```json
{
"type": "maker.openVault",
"ilk": "ETH-A"
}
```
```json
{
"type": "maker.frob",
"cdpId": "123",
"dink": "1000000000000000000", // optional
"dart": "1000" // optional
}
```
### Balancer
```json
{
"type": "balancer.swap",
"poolId": "0x...",
"kind": "givenIn",
"assetIn": "0x...",
"assetOut": "0x...",
"amount": "1000000"
}
```
### Curve
```json
{
"type": "curve.exchange",
"pool": "0x...",
"i": 0,
"j": 1,
"dx": "1000000",
"minDy": "990000" // optional
}
```
### Aggregators
```json
{
"type": "aggregators.swap1Inch",
"tokenIn": "0x...",
"tokenOut": "0x...",
"amountIn": "1000000",
"minReturn": "990000", // optional
"slippageBps": 50 // optional, default 50
}
```
## Flash Loan Strategies
Flash loans require special handling. Steps after a flash loan are executed in the callback:
```json
{
"steps": [
{
"id": "flashLoan",
"action": {
"type": "aaveV3.flashLoan",
"assets": ["0x..."],
"amounts": ["1000000"]
}
},
{
"id": "swap",
"action": {
"type": "uniswapV3.swap",
// This executes in the flash loan callback
}
}
]
}
```
## Best Practices
1. **Always use guards** for safety checks
2. **Use blinds** for sensitive values
3. **Test on fork** before live execution
4. **Start small** and increase gradually
5. **Monitor gas usage**
6. **Validate addresses** before execution
7. **Use slippage protection** for swaps
8. **Check health factors** for lending operations
## Examples
See `strategies/` directory for complete examples:
- `sample.recursive.json`: Recursive leverage
- `sample.hedge.json`: Hedging strategy
- `sample.liquidation.json`: Liquidation helper
- `sample.stablecoin-hedge.json`: Stablecoin arbitrage
## Validation
Validate your strategy before execution:
```bash
strategic validate strategy.json
```
## Execution
```bash
# Simulate
strategic run strategy.json --simulate
# Dry run
strategic run strategy.json --dry
# Explain
strategic run strategy.json --explain
# Live execution
strategic run strategy.json
```

## Remaining Issues
### High Priority (Still Need Fixing)
1. **Chain Registry Placeholder Addresses** - Many addresses are still placeholders
- Aave PoolDataProvider: `0x7B4C56Bf2616e8E2b5b2E5C5C5C5C5C5C5C5C5C5` (mainnet)
- Maker addresses: `0x19c0976f590D67707E62397C1B5Df5C4b3B3b3b3`, `0x9759A6Ac90977b93B585a2242A5C5C5C5C5C5C5C5`
- USDT Chainlink: `0x3E7d1eAB1ad2CE9715bccD9772aF5C5C5C5C5C5C5`
- Base PoolDataProvider: `0x2d09890EF08c270b34F8A3D3C5C5C5C5C5C5C5C5`
- Missing L2 protocol addresses
2. **Aggregator API Integration** - Still returns placeholder quotes
- Need to integrate 1inch API for real quotes

# Code Review: Gaps and Placeholders
## Critical Gaps
### 1. Chain Registry - Hardcoded/Incorrect Addresses
**Location**: `src/config/chains.ts`
**Issues**:
- **Line 70**: Aave PoolDataProvider address is placeholder: `0x7B4C56Bf2616e8E2b5b2E5C5C5C5C5C5C5C5C5C5`
- **Line 82**: Maker Jug address is placeholder: `0x19c0976f590D67707E62397C1B5Df5C4b3B3b3b3`
- **Line 83**: Maker DaiJoin address is placeholder: `0x9759A6Ac90977b93B585a2242A5C5C5C5C5C5C5C5`
- **Line 102**: USDT Chainlink oracle is placeholder: `0x3E7d1eAB1ad2CE9715bccD9772aF5C5C5C5C5C5C5`
- **Line 179**: Base Aave PoolDataProvider is placeholder: `0x2d09890EF08c270b34F8A3D3C5C5C5C5C5C5C5C5`
- **Missing**: Many protocol addresses for L2s (Arbitrum, Optimism, Base) are incomplete
- **Missing**: Chainlink oracle addresses for L2s are not configured
**Impact**: High - Will cause runtime failures when accessing these contracts
---
### 2. AtomicExecutor.sol - Flash Loan Callback Security Issue
**Location**: `contracts/AtomicExecutor.sol:128`
**Issue**:
```solidity
require(msg.sender == initiator || msg.sender == address(this), "Unauthorized");
```
- The check `msg.sender == address(this)` is incorrect - flash loan callback should only accept calls from the Aave Pool
- Should verify `msg.sender` is the Aave Pool address, not `address(this)`
**Impact**: Critical - Security vulnerability, could allow unauthorized flash loan callbacks
---
### 3. MakerDAO Adapter - Missing CDP ID Parsing
**Location**: `src/adapters/maker.ts:80`
**Issue**:
```typescript
return 0n; // Placeholder
```
- `openVault()` always returns `0n` instead of parsing the actual CDP ID from transaction events
- Comment says "In production, parse from Vat.cdp events" but not implemented
**Impact**: High - Cannot use returned CDP ID for subsequent operations
---
### 4. Aggregator Adapter - No Real API Integration
**Location**: `src/adapters/aggregators.ts:59-67`
**Issue**:
```typescript
// In production, call 1inch API for off-chain quote
// For now, return placeholder
const minReturn = (amountIn * BigInt(10000 - slippageBps)) / 10000n;
return {
amountOut: minReturn, // Placeholder
data: "0x", // Would be encoded swap data from 1inch API
gasEstimate: 200000n,
};
```
- No actual 1inch API integration
- Returns fake quotes that don't reflect real market prices
- No swap data encoding
**Impact**: High - Cannot use aggregators for real swaps
---
### 5. Cross-Chain Orchestrator - Complete Placeholder
**Location**: `src/xchain/orchestrator.ts`
**Issues**:
- `executeCrossChain()` returns hardcoded `{ messageId: "0x", status: "pending" }`
- `checkMessageStatus()` always returns `"pending"`
- `executeCompensatingLeg()` is empty
- No CCIP, LayerZero, or Wormhole integration
**Impact**: High - Cross-chain functionality is non-functional
---
### 6. Cross-Chain Guards - Placeholder Implementation
**Location**: `src/xchain/guards.ts:14`
**Issue**:
```typescript
// Placeholder for cross-chain guard evaluation
return {
passed: true,
status: "delivered",
};
```
- Always returns `passed: true` without any actual checks
- No finality threshold validation
- No message status polling
**Impact**: Medium - Cross-chain safety checks are bypassed
---
### 7. KMS/HSM Secret Store - Not Implemented
**Location**: `src/utils/secrets.ts:31-40`
**Issue**:
```typescript
// TODO: Implement KMS/HSM/Safe module integration
export class KMSSecretStore implements SecretStore {
// Placeholder for KMS integration
async get(name: string): Promise<string | null> {
throw new Error("KMS integration not implemented");
}
```
- All methods throw "not implemented" errors
- No AWS KMS, HSM, or Safe module integration
**Impact**: Medium - Cannot use secure secret storage in production
---
### 8. CLI Template System - Not Implemented
**Location**: `src/cli.ts:76`
**Issue**:
```typescript
// TODO: Implement template system
console.log("Template system coming soon");
```
- `strategic build --template` command does nothing
**Impact**: Low - Feature not available
---
## Implementation Gaps
### 9. Compiler - Missing Action Types
**Location**: `src/planner/compiler.ts`
**Missing Implementations**:
- `aaveV3.flashLoan` - Detected but not compiled into calls
- `aaveV3.setUserEMode` - Not in compiler
- `aaveV3.setUserUseReserveAsCollateral` - Not in compiler
- `compoundV3.withdraw` - Not in compiler
- `compoundV3.borrow` - Not in compiler
- `compoundV3.repay` - Not in compiler
- `maker.*` actions - Not in compiler
- `balancer.*` actions - Not in compiler
- `curve.*` actions - Not in compiler
- `lido.*` actions - Not in compiler
- `permit2.*` actions - Not in compiler
- `aggregators.*` actions - Not in compiler
- `perps.*` actions - Not in compiler
**Impact**: High - Most strategy actions cannot be executed
---
### 10. Flash Loan Integration - Incomplete
**Location**: `src/planner/compiler.ts:67-70`
**Issue**:
```typescript
// If flash loan, wrap calls in flash loan callback
if (requiresFlashLoan && flashLoanAsset && flashLoanAmount) {
// Flash loan calls will be executed inside the callback
// The executor contract will handle this
}
```
- No actual wrapping logic
- Calls are not reorganized to execute inside flash loan callback
- No integration with `executeFlashLoan()` in executor
**Impact**: High - Flash loan strategies won't work
---
### 11. Gas Estimation - Crude Approximation
**Location**: `src/planner/compiler.ts:233-236`
**Issue**:
```typescript
private estimateGas(calls: CompiledCall[]): bigint {
// Rough estimate: 100k per call + 21k base
return BigInt(calls.length * 100000 + 21000);
}
```
- No actual gas estimation via `eth_estimateGas`
- Fixed 100k per call is inaccurate
- Doesn't account for different call complexities
**Impact**: Medium - Gas estimates may be wildly inaccurate
---
### 12. Fork Simulation - Basic Implementation
**Location**: `src/engine.ts:185-213` and `scripts/simulate.ts`
**Issues**:
- Uses `anvil_reset` which may not work with all RPC providers
- No actual state snapshot/restore
- No calldata trace/debugging
- No revert diff analysis
- Simulation just calls `provider.call()` without proper setup
**Impact**: Medium - Fork simulation is unreliable
---
### 13. Uniswap V3 Compiler - Hardcoded Recipient
**Location**: `src/planner/compiler.ts:195`
**Issue**:
```typescript
recipient: "0x0000000000000000000000000000000000000000", // Will be set by executor
```
- Comment says "Will be set by executor" but executor doesn't modify calldata
- Should use actual executor address or strategy-defined recipient
**Impact**: High - Swaps may fail or send tokens to zero address
---
### 14. Price Oracle - Hardcoded Decimals
**Location**: `src/pricing/index.ts:90`
**Issue**:
```typescript
decimals: 18, // Assume 18 decimals for now
```
- TWAP price assumes 18 decimals for all tokens
- Should fetch actual token decimals
**Impact**: Medium - Price calculations may be incorrect for non-18-decimal tokens
---
### 15. Price Oracle - Weighted Average Bug
**Location**: `src/pricing/index.ts:146-155`
**Issue**:
```typescript
let weightedSum = 0n;
let totalWeight = 0;
for (const source of sources) {
const weight = source.name === "chainlink" ? 0.7 : 0.3;
weightedSum += (source.price * BigInt(Math.floor(weight * 1000))) / 1000n;
totalWeight += weight;
}
const price = totalWeight > 0 ? weightedSum / BigInt(Math.floor(totalWeight * 1000)) * 1000n : sources[0].price;
```
- Division logic is incorrect - divides by `totalWeight * 1000` then multiplies by 1000
- Should divide by `totalWeight` directly
- Weighted average calculation is mathematically wrong
**Impact**: High - Price calculations are incorrect
---
### 16. Permit2 - Not Integrated in Compiler
**Location**: `src/utils/permit.ts` exists but `src/planner/compiler.ts` doesn't use it
**Issue**:
- Permit2 signing functions exist but are never called
- Compiler doesn't check for `needsApproval()` before operations
- No automatic permit generation in strategy execution
**Impact**: Medium - Cannot use Permit2 to avoid approvals
---
### 17. Flashbots Bundle - Missing Integration
**Location**: `src/wallets/bundles.ts` exists but `src/engine.ts` doesn't use it
**Issue**:
- Flashbots bundle manager exists but execution engine doesn't integrate it
- No option to submit via Flashbots in CLI
- No bundle simulation before execution
**Impact**: Medium - Cannot use Flashbots for MEV protection
---
### 18. Telemetry - Simple Hash Implementation
**Location**: `src/telemetry.ts:35-38`
**Issue**:
```typescript
export function getStrategyHash(strategy: any): string {
// Simple hash of strategy JSON
const json = JSON.stringify(strategy);
// In production, use crypto.createHash
return Buffer.from(json).toString("base64").slice(0, 16);
}
```
- Comment says "In production, use crypto.createHash" but uses base64 encoding
- Not a cryptographic hash, just base64 encoding
**Impact**: Low - Hash is not cryptographically secure but functional
---
### 19. Aave V3 Adapter - Missing Error Handling
**Location**: `src/adapters/aaveV3.ts`
**Issues**:
- No validation of asset addresses
- No check if asset is supported by Aave
- No handling of paused reserves
- `withdraw()` doesn't parse actual withdrawal amount from events (line 91 comment)
**Impact**: Medium - May fail silently or with unclear errors
---
### 20. Strategy Schema - Missing Action Types
**Location**: `src/strategy.schema.ts`
**Missing from schema but adapters exist**:
- `maker.openVault`, `maker.frob`, `maker.join`, `maker.exit`
- `balancer.swap`, `balancer.batchSwap`
- `curve.exchange`, `curve.exchange_underlying`
- `lido.wrap`, `lido.unwrap`
- `permit2.permit`
- `aggregators.swap1Inch`, `aggregators.swapZeroEx`
- `perps.increasePosition`, `perps.decreasePosition`
**Impact**: High - Cannot define strategies using these actions
---
### 21. Executor Contract - Missing Flash Loan Interface
**Location**: `contracts/AtomicExecutor.sol:8-16`
**Issue**:
- Defines `IPool` interface locally but Aave v3 uses `IFlashLoanSimpleReceiver`
- Missing proper interface implementation
- Should import or define the full receiver interface
**Impact**: Medium - May not properly implement Aave's callback interface
---
### 22. Executor Tests - Incomplete
**Location**: `contracts/test/AtomicExecutor.t.sol`
**Issues**:
- Test target contract doesn't exist (calls `target.test()`)
- No actual flash loan test
- No test for flash loan callback
- Tests are minimal and don't cover edge cases
**Impact**: Medium - Contract not properly tested
---
### 23. Deploy Script - Hardcoded Addresses
**Location**: `scripts/Deploy.s.sol`
**Issue**:
- Hardcodes protocol addresses that may not exist on all chains
- No chain-specific configuration
- Doesn't verify addresses before allowing
**Impact**: Medium - Deployment may fail on different chains
---
### 24. Example Strategies - Invalid References
**Location**: `strategies/sample.recursive.json` and others
**Issues**:
- Uses `{{executor}}` placeholder in guards but no substitution logic
- Uses token addresses that may not exist
- No validation that strategies are actually executable
**Impact**: Low - Examples may not work out of the box
---
## Data/Configuration Gaps
### 25. Missing Protocol Addresses
**Missing for L2s**:
- MakerDAO addresses (only mainnet)
- Curve registry (only mainnet)

**Location**: `tests/integration/` directory is empty
**Impact**: High - No end-to-end testing
---
### 30. Foundry Tests - Minimal
**Location**: `contracts/test/AtomicExecutor.t.sol`
**Impact**: Medium - Contract has basic tests only
---
## Documentation Gaps
### 31. Missing API Documentation

# High-Priority Fixes Completed
## 1. ✅ Aggregator API Integration
**File**: `src/adapters/aggregators.ts`
**Changes**:
- Integrated 1inch API v6.0 for real-time quotes
- Added `get1InchQuote()` that calls 1inch API endpoints
- Fetches both quote and swap transaction data
- Includes fallback mechanism if API fails
- Supports API key via `ONEINCH_API_KEY` environment variable
**API Integration**:
- Quote endpoint: `https://api.1inch.dev/swap/v6.0/{chainId}/quote`
- Swap endpoint: `https://api.1inch.dev/swap/v6.0/{chainId}/swap`
- Properly handles slippage and gas estimation
**Impact**: Aggregator adapter now provides real market quotes instead of placeholders
---
## 2. ✅ Gas Estimation Improvements
**File**: `src/utils/gas.ts`
**Changes**:
- Added `estimateGasForCalls()` function that uses `eth_estimateGas` for each call
- Sums individual call estimates with 20% safety buffer
- Integrated into execution engine for accurate gas estimation
- Falls back to rough estimate if detailed estimation fails
**Integration**:
- Execution engine now uses accurate gas estimation when executor address is available

- Error handling with fallbacks
**Impact**: Cross-chain strategies can now be executed (previously placeholder)
---
## 5. ✅ Cross-Chain Guards Implementation
**File**: `src/xchain/guards.ts`
**Changes**:
- Implemented `evaluateCrossChainGuard()` with real status checking
- Added time-based timeout validation
- Added block-based finality threshold checking
- Chain-specific finality thresholds
- Status polling integration
**Features**:
- Checks message delivery status
- Validates timeout thresholds
- Chain-specific finality rules
- Proper error handling
**Impact**: Cross-chain operations now have safety guards
---
## 6. ⚠️ Chain Registry Addresses
**File**: `src/config/chains.ts`
**Status**: Added TODO comments for addresses that need verification
**Note**: Some addresses are placeholders and need to be verified:
- Aave PoolDataProvider addresses
- Maker Jug and DaiJoin addresses
- USDT Chainlink oracle
- Base PoolDataProvider
**Action Required**: These addresses should be verified against official protocol documentation before production use.
