## Verification

### On-Chain Verification

```bash
# Check contract code
cast code 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  --rpc-url http://192.168.11.250:8545

# Get token name
cast call 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "name()(string)" \
  --rpc-url http://192.168.11.250:8545

# Get token symbol
cast call 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "symbol()(string)" \
  --rpc-url http://192.168.11.250:8545

# Check deployer balance
cast call 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "balanceOf(address)(uint256)" \
  0x4A666F96fC8764181194447A7dFdb7d471b301C8 \
  --rpc-url http://192.168.11.250:8545

## Usage

### Transfer LINK Tokens

```bash
# Transfer 10 LINK to bridge contract
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  <BRIDGE_ADDRESS> \
  10000000000000000000 \
  --rpc-url http://192.168.11.250:8545 \
  --private-key $PRIVATE_KEY \
  --legacy
```

### Approve LINK for CCIP

```bash
# Approve CCIP Router to spend LINK
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "approve(address,uint256)" \
  <CCIP_ROUTER_ADDRESS> \
  1000000000000000000000 \
  --rpc-url http://192.168.11.250:8545 \
  --private-key $PRIVATE_KEY \
  --legacy
```

---

## Next Steps

### 1. Fund Bridge Contracts

Transfer LINK tokens to bridge contracts for CCIP fees:

```bash
# WETH9 Bridge: 10 LINK
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  <WETH9_BRIDGE_ADDRESS> \
  10000000000000000000 \
  --rpc-url http://192.168.11.250:8545 \
  --private-key $PRIVATE_KEY \
  --legacy

# WETH10 Bridge: 10 LINK
cast send 0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03 \
  "transfer(address,uint256)" \
  <WETH10_BRIDGE_ADDRESS> \
  10000000000000000000 \
  --rpc-url http://192.168.11.250:8545 \
  --private-key $PRIVATE_KEY \
  --legacy
```

### 2. Update Token Lists

Add LINK token to token lists:

```json
{
  "chainId": 138,
  "address": "0xb7721dD53A8c629d9f1Ba31a5819AFe250002b03",
  "name": "Chainlink Token",
  "symbol": "LINK",
  "decimals": 18,
  "logoURI": "https://raw.githubusercontent.com/trustwallet/assets/master/blockchains/ethereum/assets/0x514910771AF9Ca656af840dff83E8264EcF986CA/logo.png"
}
```

### 3. Update Database

Run migration to add LINK token to database:

```bash
psql -U explorer -d explorer \
  -f backend/database/migrations/0009_add_link_token.up.sql
```
