Optional. Use mainnet for BASE_RPC_URL and EPHEMERAL_RPC_URL, devnet for BASE_DEVNET_RPC_URL and EPHEMERAL_DEVNET_RPC_URL, or provide a custom http(s) RPC URL to override the base RPC while keeping the configured ephemeral RPC.

Optional. When true, the API uses a mock challenge for testing. Defaults to false.
