**Step 2: Configure for Monad**

Edit `packages/nextjs/scaffold.config.ts`:
```typescript
import { monadTestnet } from "viem/chains";

const scaffoldConfig = {
  targetNetworks: [monadTestnet],
  pollingInterval: 3000,   // 3 seconds (default 30000 is too slow)
};

evm_version = "prague"
solc_version = "0.8.28"

cd <project-name>
yarn install
yarn start

yarn deploy --network monadTestnet

curl -X POST https://agents.devnads.com/v1/faucet \
  -H "Content-Type: application/json" \
  -d '{"chainId": 10143, "address": "0xYOUR_BURNER_WALLET"}'
