## Configuration Updated

### ✅ .env File

Updated `.env` with documented LINK token address:
```bash
LINK_TOKEN=0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03
```

### Address Mismatch Resolution

**Issue**: CCIP Router expects LINK at `0x514910771AF9Ca656af840dff83E8264EcF986CA` (Ethereum Mainnet address), but actual deployment is at `0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03`.

**Status**: 
- ✅ Actual LINK token found and configured
- ⚠️ CCIP Router may need fee token update (if router supports changing fee token)

## Next Steps

### 1. Verify Wallet Balance

```bash
./scripts/configuration/check-link-balance-at-address.sh 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03
```

### 2. If Balance is Low

Transfer LINK tokens to wallet:
```bash
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
  <amount_wei> \
  --rpc-url http://192.168.11.211:8545 \
  --private-key <sender_private_key>
```

### 3. Fund Bridge Contracts

Once wallet has LINK, fund bridge contracts:
```bash
# WETH9 Bridge: 10 LINK
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 \
  10000000000000000000 \
  --rpc-url http://192.168.11.211:8545 \
  --private-key $PRIVATE_KEY

# WETH10 Bridge: 10 LINK
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e \
  10000000000000000000 \
  --rpc-url http://192.168.11.211:8545 \
  --private-key $PRIVATE_KEY
```
