# Contract Addresses

**⚠️ ALWAYS verify live on Chainscan.** Testnet addresses and precompiles can change.


## Networks
| Network          | Chain ID | RPC (public)                  | Explorer                          |
|------------------|----------|-------------------------------|-----------------------------------|
| Galileo Testnet  | 16602    | https://evmrpc-testnet.0g.ai  | https://chainscan-galileo.0g.ai   |
| Aristotle Mainnet| 16661    | https://evmrpc.0g.ai          | https://chainscan.0g.ai           |

## Precompiles (fixed addresses)
| Precompile       | Address                                      | Purpose                              |
