Development Setup
1. Start Proof Server
docker run -p 6300:6300 midnightnetwork/proof-server -- \
midnight-proof-server --network testnet
2. Install Lace Wallet
Download from lace.io and enable Midnight mode.
3. Get Testnet Tokens
Visit the faucet to receive tDUST for testing.

Network IDs
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
# 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)
