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

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

2. If Balance is Low

Transfer LINK tokens to wallet:

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:

# 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 \
