## 🚀 Next Steps for Testing

### 1. Set Environment Variables
Create `.env.local` in `frontend-dapp/`:
```env
VITE_THIRDWEB_CLIENT_ID=542981292d51ec610388ba8985f027d7
VITE_RPC_URL_138=http://192.168.11.250:8545
VITE_WALLETCONNECT_PROJECT_ID=your_project_id
```

### 2. Start Development Server
```bash
cd smom-dbis-138/frontend-dapp
npm install
npm run dev
```

### 3. Test BridgeButtons
1. Open browser to `http://localhost:3002`
2. Click "Custom Bridge" tab
3. Connect wallet
4. Test Wrap button (ETH → WETH9)
5. Test Approve button (WETH9 + LINK)
6. Test Bridge button (sendCrossChain)

### 4. Verify Functionality
- [ ] Wrap button works
- [ ] Approve button works
- [ ] Bridge button works

## ⚠️ Known Issues

### 1. LINK Token Not Deployed
**Status**: Known issue  
**Impact**: Bridge functionality requires LINK for fees  
**Workaround**: Deploy LINK token or use native ETH fees (if router supports)

### 2. Router Fee Token Query
**Status**: Warning  
**Impact**: Cannot verify router fee token programmatically  
**Workaround**: Manual verification or router may use different method
