# ALL Mainnet Routing Engine — AlltraAdapter & AlltraCustomBridge

Documents how **AlltraAdapter** and **AlltraCustomBridge** fit into the cross-chain routing engine for ALL Mainnet (651940) → Tezos USDtz flows.

## Overview

- **ALL Mainnet** (chainId 651940): EVM blockchain, RPC `https://mainnet-rpc.alltra.global`
- **AlltraAdapter**: Solidity contract bridging 651940 ↔ Ethereum (1)
- **AlltraCustomBridge**: On-chain bridge component used when CCIP/LiFi do not support 651940

## Routing Engine Integration

### Bridge Capability Matrix

The `dbis_core` bridge capability matrix (`bridge-capability-matrix.ts`) includes:

| Provider        | Source     | Destination | Assets                    | Status  |
|-----------------|------------|-------------|---------------------------|---------|
| AlltraAdapter   | 651940     | 1           | USDC, USDT, AUSDC, AUSDT, WETH | active  |
| AlltraAdapter   | 1          | 651940      | USDC, USDT, WETH          | active  |

### Route Planner (ALL Mainnet → Tezos USDtz)

The route planner supports `source_chain_id=651940` with this 4-hop path:

1. **ALL_MAINNET SWAP** — source asset → AUSDC (`0xa95EeD79f84E6A0151eaEb9d441F9Ffd50e8e881`) via AlltraDEX / EnhancedSwapRouter
2. **ALL_MAINNET BRIDGE** — AlltraAdapter: AUSDC → USDC on Ethereum
3. **HUB_EVM BRIDGE** — Wrap Protocol (or Allbridge): USDC → Tezos
4. **TEZOS SWAP** — USDC → USDtz via Plenty

### Chain Label Mapping (TRPE / EO)

The Transaction Router + Policy Engine maps chain labels to IDs:

| Label       | Chain ID |
|-------------|----------|
| CHAIN138    | 138      |
| ALL_MAINNET | 651940   |
| HUB_EVM     | 1        |
| TEZOS       | 1729     |

## Contract References

- **AlltraAdapter**: `smom-dbis-138/contracts/bridge/adapters/evm/AlltraAdapter.sol`
- **Chain Registry**: Uses chain type "EVM", identifier "ALL-Mainnet" for 651940

## API Endpoints

- **POST /v1/routes/chain138-to-usdtz** (multi-chain-execution): Accepts `source_chain_id=651940`
- **POST /api/v1/routes/chain138-to-usdtz** (dbis_core): Same
