# Bridge Chains Implementation - Completion Summary
|
||
|
||
**Last Updated:** 2026-02-01
|
||
**Document Version:** 1.0
|
||
**Status:** Active Documentation
|
||
|
||
---
|
||
|
||
**Date:** 2026-01-31
|
||
**Status:** ✅ All recommended next steps complete
|
||
|
||
---
|
||
|
||
## Summary
|
||
|
||
All three recommended implementation phases have been completed:
|
||
|
||
1. **Phase 1:** Gnosis Chain, Celo, Wemix added to CCIP bridge configuration
|
||
2. **Phase 2:** Polygon and Optimism added to Li.Fi settlement layer
|
||
3. **Phase 6:** Li.Fi integrated into Go bridge aggregator
|
||
|

|
||
|
||
## Phase 1: CCIP Bridge Configuration
|
||
|
||
### Files Modified
|
||
|
||
- **`smom-dbis-138/frontend-dapp/src/config/bridge.ts`**
|
||
- Added `GNOSIS`, `CELO`, `WEMIX` to `CHAIN_SELECTORS`
|
||
- Selectors: Gnosis `465200170687744372`, Celo `1346049177634351622`, Wemix `5142893604156789321`
|
||
|
||
- **`smom-dbis-138/config/bridge.config.example.ts`**
|
||
- Added Gnosis Chain (100), Celo (42220), Wemix (1111) to `destinations`
|
||
- Updated `allowedDestinations` in `allowedTokens` for both native ETH and WETH
|
||
|
||
- **`smom-dbis-138/docs/deployment/BRIDGE_CONFIGURATION.md`**
|
||
- Updated Chain Selectors Reference table with Gnosis, Celo, Wemix
|
||
|
||
### Next Steps (Deployment) — completed in repo
|
||
|
||
To enable CCIP bridging to these chains, follow the runbook and script:
|
||
|
||
1. **Deploy** CCIPWETH9Bridge and CCIPWETH10Bridge on Gnosis, Celo, Wemix (per [CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md](../07-ccip/CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md)).
|
||
2. **Configure** destinations: run `smom-dbis-138/scripts/deployment/complete-config-ready-chains.sh` (adds Chain 138 ↔ Gnosis/Celo/Wemix bidirectionally).
|
||
3. **Fund** each bridge with LINK for CCIP fees (~10 LINK per bridge).
|
||
|
||
See [CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md](../07-ccip/CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md) and [ENV_CONFIG_READY_CHAINS.example](../../smom-dbis-138/docs/deployment/ENV_CONFIG_READY_CHAINS.example).

|
||
|
||
## Phase 2: Li.Fi Settlement Layer
|
||
|
||
### Files Modified
|
||
|
||
- **`alltra-lifi-settlement/src/config/chains.ts`**
|
||
- Added `POLYGON` config (chain 137, USDC `0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359`)
|
||
- Added `OPTIMISM` config (chain 10, USDC `0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85`)
|
||
- Updated `isSupportedInboundChain()` to include Polygon and Optimism
|
||
|
||
- **`alltra-lifi-settlement/docs/CHAIN_SUPPORT.md`**
|
||
- Added Polygon and Optimism to support matrix
|
||
- Added verification status for both chains
|
||
|
||
### Li.Fi Settlement Chains (Total: 5)
|
||
|
||
| Chain | Chain ID | Status |
|
||
|-------|----------|--------|
|
||
| Ethereum Mainnet | 1 | ✅ |
|
||
| Base | 8453 | ✅ |
|
||
| Arbitrum One | 42161 | ✅ |
|
||
| Polygon | 137 | ✅ |
|
||
| Optimism | 10 | ✅ |
