## 🔧 Verification Methods

### Method 1: Automated Script (Recommended)

```bash
cd /home/intlc/projects/smom-dbis-138
./scripts/deployment/verify-mainnet-etherscan.sh
```

**Requirements**:
- `ETHERSCAN_API_KEY` set in `.env`
- Foundry installed
- Contracts compiled

---

### Method 2: Manual Foundry Verification

#### CCIPWETH9Bridge

```bash
# Encode constructor arguments
CONSTRUCTOR_ARGS=$(cast abi-encode "constructor(address,address,address)" \
  0x80226fc0Ee2b096224EeAc085Bb9a8cba1146f7D \
  0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  0x514910771AF9Ca656af840dff83E8264EcF986CA)

# Verify contract
forge verify-contract \
  --chain-id 1 \
  --num-of-optimizations 200 \
  --watch \
  --constructor-args "$CONSTRUCTOR_ARGS" \
  0x3304b747E565a97ec8AC220b0B6A1f6ffDB837e6 \
  contracts/ccip/CCIPWETH9Bridge.sol:CCIPWETH9Bridge \
  $ETHERSCAN_API_KEY
```

#### CCIPWETH10Bridge

```bash
# Encode constructor arguments
CONSTRUCTOR_ARGS=$(cast abi-encode "constructor(address,address,address)" \
  0x80226fc0Ee2b096224EeAc085Bb9a8cba1146f7D \
  0xf4BB2e28688e89fCcE3c0580D37d36A7672E8A9f \
  0x514910771AF9Ca656af840dff83E8264EcF986CA)

# Verify contract
forge verify-contract \
  --chain-id 1 \
  --num-of-optimizations 200 \
  --watch \
  --constructor-args "$CONSTRUCTOR_ARGS" \
  0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e \
  contracts/ccip/CCIPWETH10Bridge.sol:CCIPWETH10Bridge \
  $ETHERSCAN_API_KEY
```
