First, you will need access to EnterCoin full node RPC interface. You can use properly configured remote one, but it would significantly affect performance and potentially also security of your deployment. Please consider security implications of opening HBFT RPC to outside access. Especially if you enable "personal" commands on your node while keeping your account keys in the Hyperthereum key store. We recommend using local IPC channel for communication between an EnterChain node and the API server. The IPC interface is available by default.
