### 2. CCIPReceiver

**Address**: `0x95007eC50d0766162F77848Edf7bdC4eBA147fb4`

**Status**: ⚠️ **DEPLOYED BUT PENDING VERIFICATION**

- **Deployment Method**: Foundry script (`DeployCCIPReceiver.s.sol`)
- **On-Chain Verification**: ⚠️ Code not found on-chain (may be pending)
- **Configuration**:
  - CCIP Router: `0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e`
  - Oracle Aggregator: `0x99b3511a2d315a497c8112c1fdd8d508d4b1e506`

**Deployment Transaction**:
- Hash: `0x4305136a53474bfa98724f4d03b53d3db816eb6b2e0f166d07ca949da7c019f4`
- Log: `/home/intlc/projects/smom-dbis-138/broadcast/DeployCCIPReceiver.s.sol/138/run-latest.json`
- Status: ⚠️ Transaction may be pending confirmation

**Issue**: Contract code not found on-chain. Possible reasons:
1. Transaction still pending (not yet mined)
2. Transaction failed but script reported success
3. RPC node sync delay

**Action Required**: 
- Check transaction receipt on block explorer
- Verify transaction was actually broadcast (not dry-run)
- Re-deploy if transaction failed

## ⚠️ Issues and Recommendations

### Issue 1: CCIPReceiver Not Verified On-Chain

**Status**: ⚠️ **PENDING**

**Details**:
- Deployment script reported success
- Contract address assigned: `0x95007eC50d0766162F77848Edf7bdC4eBA147fb4`
- Transaction hash: `0x4305136a53474bfa98724f4d03b53d3db816eb6b2e0f166d07ca949da7c019f4`
- On-chain code not found (only 3 bytes, likely empty)

**Possible Causes**:
1. Transaction still pending (not mined yet)
2. Transaction failed but script didn't detect it
3. RPC node sync delay
4. Transaction was simulated (dry-run) instead of broadcast

**Recommended Actions**:
1. Check transaction receipt on block explorer
2. Verify transaction was actually broadcast (check `--broadcast` flag was used)
3. Wait for block confirmation if transaction is pending
4. Re-deploy if transaction failed:
   ```bash
   cd /home/intlc/projects/smom-dbis-138
   forge script script/DeployCCIPReceiver.s.sol:DeployCCIPReceiver \
     --rpc-url http://192.168.11.250:8545 \
     --broadcast --legacy --gas-price 20000000000 --via-ir
   ```

---

## 📄 Next Steps

### Immediate Actions

   - Check: https://explorer.d-bis.org/tx/0x4305136a53474bfa98724f4d03b53d3db816eb6b2e0f166d07ca949da7c019f4
   - If failed, re-deploy CCIPReceiver

2. **Run Database Migration** (Optional)
   ```bash
   psql -U explorer -d explorer -f backend/database/migrations/0009_add_link_token.up.sql
   ```

### Future Enhancements
