# Start on Robinhood Chain testnet without mixing networks

Keep chain identity, test funds, deployments and endpoints in one explicit configuration.

## Testnet is a separate environment

Robinhood Chain publishes a public testnet for development. Its test tokens have no production value, and a contract deployed there is separate from a mainnet contract. Supanode's production RPC documentation and a public testnet endpoint should not be treated as the same service.

## Verify the configuration

| Setting | Mainnet | Testnet |
| --- | --- | --- |
| Chain ID | 4663 / 0x1237 | 46630 / 0xb626 |
| Native gas currency | ETH | Test ETH |
| Public RPC | https://rpc.mainnet.chain.robinhood.com | https://rpc.testnet.chain.robinhood.com |
| Explorer | robinhoodchain.blockscout.com | explorer.testnet.chain.robinhood.com |

These values come from Robinhood's connection documentation, checked on 21 October 2026. Public endpoints are rate-limited; use them as development infrastructure with the documented constraints.

## Run a read-only check

```
curl https://rpc.testnet.chain.robinhood.com \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'
```

The expected chain result is 0xb626. Read the faucet linked by the official documentation for test ETH. Eligibility and cooldowns are faucet-specific, so do not bake an unverified allocation into an onboarding flow.

## Promote deliberately

1.  Keep a dedicated test wallet with no production funds.
2.  Deploy and test a small contract, then save its address and compiler settings.
3.  Prepare a separate mainnet configuration and verify eth\_chainId again.
4.  Redeploy intentionally and update contract addresses, explorer links and monitoring together.
