# Midnight Network Infrastructure

Configure and manage Midnight Network components for dApp development.

## Quick Reference

| Service          | Testnet-02 URL                                                |
| ---------------- | ------------------------------------------------------------- |
| **Indexer**      | `https://indexer.testnet-02.midnight.network/api/v1/graphql`  |
| **Indexer WS**   | `wss://indexer.testnet-02.midnight.network/api/v1/graphql/ws` |
| **RPC Node**     | `https://rpc.testnet-02.midnight.network`                     |
| **Proof Server** | `http://localhost:6300` (local)                               |
| **Faucet**       | `https://faucet.testnet-02.midnight.network`                  |

## Development Setup

### 1. Start Proof Server

```bash
docker run -p 6300:6300 midnightnetwork/proof-server -- \
  midnight-proof-server --network testnet
```

### 2. Install Lace Wallet

Download from [lace.io](https://www.lace.io/) and enable Midnight mode.

### 3. Get Testnet Tokens

Visit the faucet to receive tDUST for testing.

```

## Network IDs

```typescript
import { NetworkId, setNetworkId } from '@midnight-ntwrk/midnight-js-network-id';

// Always set before using providers
setNetworkId(NetworkId.TestNet);

// Available networks
enum NetworkId {
  DevNet = 'DevNet', // Developer network (not persistent)
  TestNet = 'TestNet', // Persistent testnet
  MainNet = 'MainNet', // Midnight mainnet
  Undeployed = 'Undeployed', // Local testing
}
```

## Health Checks

```bash
# Check proof server
curl http://localhost:6300/health

# Check indexer
curl https://indexer.testnet-02.midnight.network/api/v1/graphql \
  -H 'Content-Type: application/json' \
  -d '{"query":"{ __typename }"}'
```

## Common Issues

| Issue                    | Solution                                 |
| ------------------------ | ---------------------------------------- |
| Proof generation timeout | Increase timeout, check Docker resources |
| Connection refused       | Ensure proof server is running           |
| Network mismatch         | Verify NetworkId matches wallet          |
| Insufficient funds       | Get tDUST from faucet                    |

## Best Practices

- ✅ Start proof server before dApp
- ✅ Use wallet's service URIs when available
- ✅ Set NetworkId before provider initialization
- ✅ Monitor proof server logs for errors
- ❌ Don't hardcode network URLs (use config)
