T1.2 Bridge Resolution - Complete Execution Summary

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation

---

Date: 2026-01-18
Status: ✅ PHASE 1 & 2 COMPLETE | 📋 PHASE 3 READY FOR EXECUTION

---

🎯 Objective

Resolve ChainID 138 bridge interface issue by deploying updated contracts with full interface (addDestination(), getDestinationChains()).

Goal: Enable bidirectional bridge configuration (ChainID 138 ↔ Mainnet)

---

✅ Completed Tasks

Phase 1: Verify Current State ✅

• ✅ Task 1.1: Test bridge functionality analysis
• ✅ Task 1.2: Event log verification (no events found)
• Result: Confirmed missing functions, no destinations configured

Phase 2: Decision ✅

• ✅ Selected Option A: Contract Upgrade/Update
• Rationale: Full functionality, long-term solution, matches Mainnet interface

Phase 3: Implementation Preparation ✅

• ✅ Task 3.1: State extraction complete
• ✅ Task 3.3: Migration planning complete

⚠️ Important Notes

1. Router Verification: Verify router address 0x99b3511a2d315a497c8112c1fdd8d508d4b1e506 is correct CCIP router
2. LINK Token: Verify LINK address 0x514910771AF9Ca656af840dff83E8264EcF986CA is correct
3. Old Contracts: Old bridge addresses cannot be changed (immutable), new addresses will be used
4. Breaking Change: All integrations must update to new bridge addresses after deployment
