|
||
|
||
## 2. DEX and Aggregator Routing — What’s Available
|
||
|
||
### 2.1 On-Chain Routing (Chain 138)
|
||
|
||
- **Live today:**
|
||
- **DODO-style PMM** via **DODOPMMIntegration** and **DODOPMMProvider**.
|
||
- **Three pools:** cUSDT/cUSDC, cUSDT/USDT, cUSDC/USDC.
|
||
- Swaps: use pool address + `swapCUSDTForUSDC`, `swapCUSDTForUSDT`, `swapCUSDCForUSDC`, etc., with approval on the integration contract.
|
||
- **Designed, not deployed:**
|
||
- **EnhancedSwapRouter** — size/slippage/liquidity-based routing across Uniswap V3, Dodoex PMM, Balancer, Curve, 1inch. To be used when Uniswap/Balancer/Curve pools exist on 138.
|
||
|
||
**Routing logic (when EnhancedSwapRouter is deployed):**
|
||
- By size: small (<$10k) → Uniswap V3 / Dodoex; medium ($10k–$100k) → Dodoex → Balancer → Uniswap V3; large (>$100k) → Dodoex → Curve → Balancer.
|
||
- By slippage/liquidity: low slippage → Dodoex (PMM); medium → Balancer; high → Curve.
|
||
|
||
**References:**
|
||
- [PMM_DEX_ROUTING_STATUS](11-references/PMM_DEX_ROUTING_STATUS.md)
|
||
- [DEX_AND_AGGREGATORS_CHAIN138_EXPLAINER](04-configuration/DEX_AND_AGGREGATORS_CHAIN138_EXPLAINER.md)
|
||
|
||
---
|
||
|
||
### 2.2 Token-Aggregation API (Off-Chain Quotes)
|
||
|
||
- **Single-hop quote:** `GET /api/v1/quote?chainId=138&tokenIn=&tokenOut=&amountIn=` → best direct-pool quote from indexed DODO (and Uniswap if configured).
|
||
- **Token/pool discovery:** `GET /api/v1/tokens?chainId=138`, `/api/v1/tokens/:address/pools`, `/api/v1/report/token-list`.
|
||
- **Bridge:** `GET /api/v1/bridge/routes`, `/api/v1/token-mapping?fromChain=138&toChain=1`.
|
||
- **Limitation:** Single-hop only; no N-hop pathfinding.
|
||
|
||
---
|
||
|
||
### 2.3 Swap–Bridge–Swap (Cross-Chain)
|
||
|
||
- **Orchestration:** `POST /api/bridge/quote` — can return optional **sourceSwapQuote** and **destinationSwapQuote** in addition to bridge route.
|
||
- **On-chain (optional):** **SwapBridgeSwapCoordinator** — deploy when a single tx “swap (source) → bridge → swap (destination)” is required.
|
||
|
||
---
|
||
|
||
### 2.4 External DEX Aggregators (1inch, ParaSwap, 0x, Li.Fi)
|
||
|
||
- **1inch, ParaSwap, 0x:** Integrated in **alltra-lifi-settlement** for quotes on supported chains. **Chain 138 is not supported** by these aggregators unless they add it; to use them with 138, they would need to add the chain and index DODO PMM (and any other DEX on 138).
|
||
- **Li.Fi:** Cross-chain routing; **Chain 138 not supported**. Use **CCIP** for 138 ↔ Ethereum/L2.
|
||
- **Explorer bridge aggregator:** Uses Li.Fi, Socket, Squid, Symbiosis, Relay, Stargate for **bridge routes**, not for on-chain DEX on 138.
|
||
|
||
**Practical today:** Use **token-aggregation** for quotes and **DODOPMMIntegration** (or DODOPMMProvider) for execution on Chain 138.
|
||
|
||

|
||
|
||
### 2.5 Routing Summary Table
|
||
|
||
| Capability | Available | Where |
|
||
|------------|------------|--------|
|
||
| Single-hop quote (API) | Yes | `GET /api/v1/quote` |
|
||
| DODO PMM on-chain swaps | Yes | DODOPMMIntegration + three pools; DODOPMMProvider |
|
||
| Multi-provider one-leg routing | No (router not deployed) | Would be EnhancedSwapRouter |
|
||
| N-hop path (A→B→C on one chain) | No | No graph-based multi-hop API |
|
||
| Swap–bridge–swap (cross-chain) | Yes (orchestration) | QuoteService + optional SwapBridgeSwapCoordinator |
|
||
| 1inch / ParaSwap / 0x on 138 | No | Aggregators do not support Chain 138 yet |
|
||

|
||
|
||
## 3. On-Ramp and Off-Ramp
|
||
|
||
### 3.1 Ramp Providers (Implemented)
|
||
|
||
- **MoonPay** — On-ramp + Off-ramp
|
||
- **Ramp Network** — On-ramp + Off-ramp
|
||
- **Onramper** — Aggregator (on-ramp + quotes)
|
||
- **Transak** — On-ramp + Off-ramp
|
||
- **Banxa** — On-ramp + Off-ramp
|
||
- **Coinbase Ramps** — On-ramp + Off-ramp
|
||
- **Stripe Crypto** — On-ramp
|
||
- **Cybrid** — On-ramp + Off-ramp
|
||
- **Sardine** — On-ramp
|
||
- **HoneyCoin** — Off-ramp
|
||
|
||
**API:** `POST /ramps/on-ramp/session`, `POST /ramps/off-ramp/session`, `GET /ramps/quote`, `GET /ramps/providers` (metamask-integration).
|
||
**API keys:** See MASTER_SECRETS_INVENTORY, API_KEYS_REQUIRED (e.g. MOONPAY_API_KEY, RAMP_NETWORK_API_KEY, ONRAMPER_API_KEY).
|
||
|
||
---
|
||
|
||
### 3.2 User Flows (Chain 138)
|
||
|
||
- **On-ramp (fiat → crypto on 138):**
|
||
1. User chooses **Buy** in companion/dApp.
|
||
2. Selects a ramp-supported chain (e.g. **Ethereum Mainnet**).
|
||
3. Completes purchase via ramp (MoonPay, Ramp, etc.) → funds on mainnet.
|
||
4. Uses **Bridge** to send assets **Mainnet → Chain 138**.
|
||
5. Assets on 138 for gas, swaps, dApps.
|
||
|
||
- **Off-ramp (crypto on 138 → fiat):**
|
||
1. User uses **Bridge** to send **Chain 138 → Ethereum Mainnet**.
|
||
2. After confirmation, opens companion/dApp **Sell** (off-ramp).
|
||
3. Selects **Ethereum Mainnet** and completes sale via ramp provider.
|
||
4. Fiat to linked bank/payment per provider terms.
|
||
|
||
**Note:** Ramps today target supported public chains (e.g. mainnet). Chain 138 native on-ramp/off-ramp would require ramp providers to add 138 (see ON_RAMP_INTEGRATION_GUIDE, CONSENSYS_OUTREACH_PACKAGE).

||
|
||
## 4. Fireblocks
|
||
|
||
- **Purpose:** Institutional custody and Web3 operations on Chain 138.
|
||
- **Dedicated RPC (Chain 138):** One node is reserved for Fireblocks so traffic is isolated from public and other tenant RPCs.
|
||
- **VMID:** 2301 (besu-rpc-private-1).
|
||
- **LAN:** `http://192.168.11.232:8545`, `ws://192.168.11.232:8546`.
|
||
- **Public:** `https://rpc-fireblocks.d-bis.org`, `wss://ws.rpc-fireblocks.d-bis.org`.
|
||
- **Fireblocks Console:** Add custom network with RPC URL above, Chain ID **138**, optional WebSocket URL.
|
||
- **Fireblocks Web3 Provider (SDK):** Use `rpcUrl: "https://rpc-fireblocks.d-bis.org"` (or env `RPC_URL_138_FIREBLOCKS`) with `@fireblocks/fireblocks-web3-provider`.
|
||
- **REST API:** Use Chain ID **138** for Create Transaction etc.; backend uses custom network config for 138.
|
||
- **Optional:** Fireblocks Network Link / IP allowlisting — restrict to the Fireblocks-dedicated node (2301) only.
