# Current Status & Token Routing / Token-Aggregation (Incl. Multihop)
|
||
|
||
Companion to [MASTER_CONTRACTS_AND_INFRASTRUCTURE_LIST.md](MASTER_CONTRACTS_AND_INFRASTRUCTURE_LIST.md). This doc covers: **current status** of all major components, **token-aggregation** API and routing, and **multihop** routing (on-chain and off-chain).
|
||
|
||
---
|
||
|
||
## 1. Current status overview
|
||
|
||
| Area | Status | Notes |
|
||
|------|--------|--------|
|
||
| **Contracts (Solidity)** | Implemented | Full repo: bridges, vault, reserve, oracles, DEX/PMM, registries, adapters. **Build:** `forge build` currently fails due to missing `contracts/emoney/` files; all other contracts (dex, vault, reserve, bridge, ccip, nft, etc.) are present and consistent. |
|
||
| **CCIP bridges** | Deployed (mainnet refs) | WETH9/WETH10 bridges and router addresses documented for Ethereum and other chains; Chain 138 deployment per runbooks. |
|
||
| **Trustless bridge** | Implemented + deployed (Lockbox 138) | Lockbox138 on Chain 138; Ethereum stack (InboxETH, BondManager, etc.) deployable per `script/bridge/trustless/DeployTrustlessBridge.s.sol`. |
|
||
| **Oracles** | Implemented | XAUOracle, ReserveSystem, OraclePriceFeed, PriceFeedKeeper, PMMPriceProvider; optional ReserveSystem on DODOPMMIntegration. |
|
||
| **Mappers** | Implemented | AddressMapper (138), AddressMapperEmpty (other chains); deploy scripts available. |
|
||
| **Reserve system** | Implemented | ReserveSystem, OraclePriceFeed, keeper; SetupPriceFeeds and DeployReserveSystem scripts. |
|
||
| **Vault system** | Implemented | Ledger, Vault, XAUOracle, VaultFactory, CollateralAdapter, Liquidation, RateAccrual, PMMPriceProvider. |
|
||
| **PMM / DEX** | Implemented | DODOPMMIntegration (oracle-backed getPoolPriceOrOracle), DODOPMMProvider, PrivatePoolRegistry; pool indexer can ingest from DODOPMMIntegration when `CHAIN_138_DODO_PMM_INTEGRATION` is set. |
|
||
| **Token-aggregation service** | Implemented & runnable | Node service; indexes tokens/pools (UniswapV2/V3, DODO PMM from integration or PoolManager); report, quote, bridge, token-mapping APIs. Requires DB (PostgreSQL/TimescaleDB) and RPC. |
|
||
| **Orchestration (bridge quote)** | Implemented | QuoteService (swap+bridge+swap); optional EnhancedSwapRouter source/destination quotes. |
|
||
| **Token mapping (multichain)** | Implemented | `config/token-mapping.json`, `config/token-mapping-multichain.json`; token-aggregation exposes `/api/v1/token-mapping` when run from monorepo with loader. |
|

## 3. Token routing capabilities
|
||
|
||
### 3.1 Token-aggregation (API)
|
||
|
||
- **Quote:** Single-hop only. `GET /api/v1/quote` uses the pool DB to find pools that contain the (tokenIn, tokenOut) pair and returns the best constant-product quote. It does **not** compute multi-hop paths (e.g. A → B → C).
|
||
- **Pools:** Indexed from UniswapV2 (PairCreated), UniswapV3 (PoolCreated), and DODO. DODO pools are sourced from either:
|
||
- **PoolManager** (ABI: `allPools`, `poolRegistry`) when `CHAIN_138_DODO_POOL_MANAGER` is set, or
|
||
- **DODOPMMIntegration** (ABI: `getAllPools`, `getPoolConfig`, `getPoolReserves`, `getPoolPriceOrOracle`) when `CHAIN_138_DODO_PMM_INTEGRATION` is set.
|
||
- **Token mapping:** Cross-chain address resolution for bridge UIs (138↔651940 and other pairs) via `token-mapping` endpoints and `config/token-mapping-multichain.json` (or loader).
|
||
|
||
### 3.2 On-chain routing (multiprotocol, size-based)
|
||
|
||
- **EnhancedSwapRouter** (`contracts/bridge/trustless/EnhancedSwapRouter.sol`):
|
||
- **WETH → stablecoin:** Multi-provider routing by size: Uniswap V3, Dodoex PMM, Balancer, Curve, 1inch. Size categories: small (< $10k), medium ($10k–$100k), large (> $100k). Returns best quote across enabled providers.
|
||
- **Arbitrary pair:** `swapTokenToToken(tokenIn, tokenOut, amountIn, amountOutMin)` when a Dodoex pool is configured for that pair (single hop).
|
||
- **Quotes:** `getQuotes(stablecoinToken, amountIn)` returns provider list and amounts.
|
||
- Not N-hop pathfinding (e.g. A→B→C) on-chain; it selects among different DEXs for one leg (WETH↔stable).
|
||
|
||
### 3.3 Swap–bridge–swap (multihop across chains)
|
||
|
||
- **SwapBridgeSwapCoordinator** (on-chain): Coordinates **swap (source) → bridge → swap (destination)** in one flow. One hop on source, bridge, one hop on destination.
|
||
- **Orchestration QuoteService** (`orchestration/bridge/quote-service.ts`):
|
||
- **POST /api/bridge/quote** (orchestration): Bridge transfer quote; optionally includes **sourceSwapQuote** (e.g. EnhancedSwapRouter on source) and **destinationSwapQuote** (destination swap router) for swap+bridge+swap.
|
||
- Requires `RPC_URL`, `BRIDGE_REGISTRY_ADDRESS`; optional `ENHANCED_SWAP_ROUTER_ADDRESS`, `DESTINATION_RPC_URL`, `DESTINATION_SWAP_ROUTER_ADDRESS`.
|
||
|
||
### 3.4 Liquidity provider layer
|
||
|
||
- **LiquidityManager** + **DODOPMMProvider**: DODOPMMProvider returns quotes via `getPoolPriceOrOracle` (oracle-backed when ReserveSystem set on DODOPMMIntegration). Used as one liquidity source in a multi-provider setup; no pathfinding in this contract.
|
||

|
||
|
||
## 4. Multihop routing — summary
|
||
|
||
| Layer | Multihop? | What exists |
|
||
|-------|-----------|-------------|
|
||
| **Token-aggregation API** | No | Single-hop quote only (best direct pool for tokenIn/tokenOut). |
|
||
| **EnhancedSwapRouter** | No (single leg) | Multi-**provider** choice for one leg (WETH↔stable); optional single-leg Dodoex for arbitrary pair when pool configured. |
|
||
| **SwapBridgeSwapCoordinator** | Yes (cross-chain) | Swap (source) → bridge → swap (destination). |
|
||
| **Orchestration QuoteService** | Yes (swap+bridge+swap) | Quote for bridge + optional source/destination swap quotes. |
|
||
| **N-hop path (A→B→C on one chain)** | No | No generic A→B→C path finder in API or on-chain (e.g. no graph-based multi-hop swap API). |
|
||

|
||
|
||
## 5. Config and env affecting token routing
|
||
|
||
- **Token-aggregation:** `CHAIN_138_RPC_URL`, `CHAIN_651940_RPC_URL`, `DATABASE_URL`, `CHAIN_138_DODO_PMM_INTEGRATION` (and optionally `CHAIN_138_DODO_POOL_MANAGER`), canonical token env vars (`CUSDC_ADDRESS_138`, etc.).
|
||
- **Bridge routes:** `LOCKBOX_138`, `INBOX_ETH`, optional `BRIDGE_LIST_JSON_URL`.
|
||
- **Token mapping:** `config/token-mapping-multichain.json` (or loader from `config/token-mapping-loader.cjs`) when service runs from monorepo.
|
||
- **Orchestration quote:** `RPC_URL`, `BRIDGE_REGISTRY_ADDRESS`, `ENHANCED_SWAP_ROUTER_ADDRESS`, `DESTINATION_RPC_URL`, `DESTINATION_SWAP_ROUTER_ADDRESS`.
