Connect to a public node

NodeChain gives you the possibility to connect your own remote nodes to use the Wrapper APIs.

To do so, first follow the steps below:

1. Start NodeChain and choose the currency and network that most closely resembles the one of your remote node:

$ ./nodechain.py start

---------------------------------------------------
===================================================
                CONNECTOR CONFIG
===================================================
Port to start: 60000
Port to start (SSL): 443
Starting network nodechain-network.
nodechain-network is already started
Starting connector and reverse proxy... This might take a while.
Connector has been started
===================================================
                BLOCKCHAIN SELECTION
===================================================
[OFF]          1.Bitcoin
[OFF]          2.Ethereum
[OFF]          3.Bitcoin-cash
[OFF]          4.Terra
               5.Exit
Please choose the blockchain that you want to use to build up/stop the node(1-5): 2
===================================================
                NETWORK SELECTION
===================================================
[OFF]          1.Regtest
[OFF]          2.Testnet
[OFF]          3.Mainnet
               4.Exit
Please choose the network that you want to use (1-4): 2
Please choose the directory to save blockchain data (/srv/nodechain-node/eth_testnet): 

2. Check the option to start a remote node and indicate that you want to configure the API with your own endpoints:

Do you want to connect to a remote node?: [y/N]: y
Do you want to use the default configuration for the API  [Y/n]: n
You need to configure the endpoints to start the node.
Please, introduce a value for rpcEndpoint: https://ropsten.infura.io/v3/xxxxxxxxxxxxxxxxxxxxxxxxxxxx1592
Please, introduce a value for wsEndpoint: wss://ropsten.infura.io/ws/v3/xxxxxxxxxxxxxxxxxxxxxxxxxxxx1592
Please, introduce a value for indexerEndpoint: http://postgrest-testnet:3000
eth testnet has registered succesfully in the connector

Congratulations! Now you can use the remote node to handle any request from the Wrapper API.

If you want to use these endpoints everytime you start this currency and network, you can change the config.json file to set this configuration as default
