## Session Changes (2026-02-16)

- **CCIPLogger contract**: Created `contracts/ccip-integration/CCIPLogger.sol` (was missing)
- **Foundry deploy**: `script/DeployCCIPLogger.s.sol` and updated `DeployCCIPLoggerOnly.s.sol` now deploy CCIPLogger
- **Hardhat config**: Added networks BSC, Polygon, Gnosis, Cronos for CCIPLogger
- **deploy-ccip-logger-multichain.js**: New script; `npm run deploy:logger:bsc|polygon|gnosis|cronos`
- **package.json**: New deploy:logger:* scripts
- **.env**: Added MULTICALL_CRONOS, CREATE2_FACTORY_CRONOS, ORACLE_AGGREGATOR_CRONOS, ORACLE_PROXY_CRONOS
- **fix-nonce-and-retry.sh**: Helper to clear broadcast cache before retrying (nonce mismatch)

## Blocked

- **Chain 138** — Resolve stuck tx with `scripts/flush-stuck-tx-rpc-and-validators.sh --full` or replacement tx with higher gas
- **Compliant Fiat Tokens on Cronos** — Needs ~19 CRO
- **ISO-4217W on Cronos** — ✅ Deployed (use `--slow` flag to avoid nonce mismatch)

## Next Steps

1. **Chain 138**: Ensure RPC reachable; resolve stuck tx if any.
2. **Cronos ISO-4217W retry** (if needed): Use `--slow` and alternative RPC to avoid nonce/rate issues:  
   `CRONOS_RPC_URL=https://cronos-evm.publicnode.com rm -rf cache/DeployISO4217WSystem.s.sol/25 broadcast/DeployISO4217WSystem.s.sol/25 && forge script script/deploy/iso4217w/DeployISO4217WSystem.s.sol:DeployISO4217WSystem --rpc-url "$CRONOS_RPC_URL" --broadcast --slow`
3. **CCIPLogger**: Deployed on Cronos at 0x176a1b6Aa59F24B3aa65F2b697AB262Bca9093B5 (CCIP_LOGGER_CRONOS in .env).
4. **Compliant Fiat Tokens**: Add ~15 CRO, run with CREATE2_FACTORY_ADDRESS.
