Get started with a reliable Ronin RPC endpoint to use the tools below.

​
web3.js

Build DApps using web3.js and Ronin nodes deployed with Chainstack.
  1. Install web3.js.
  2. Connect over HTTP or WebSocket.

​
HTTP

Use the HttpProvider object to connect to your node HTTPS endpoint and get the latest block number: 
const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.HttpProvider('YOUR_CHAINSTACK_ENDPOINT'));

web3.eth.getBlockNumber().then(console.log);
where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password.

​
WebSocket

Use the WebsocketProvider object to connect to your node WSS endpoint and get the latest block number: 
const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.WebsocketProvider('YOUR_CHAINSTACK_ENDPOINT'));

web3.eth.getBlockNumber().then(console.log);
where YOUR_CHAINSTACK_ENDPOINT is your node WSS endpoint protected either with the key or password.

​
web3.py

Build DApps using web3.py and Ronin nodes deployed with Chainstack.
  1. Install web3.py.
  2. Connect over HTTP or WebSocket. See also EVM node connection: HTTP vs WebSocket.

​
HTTP

Use the HTTPProvider to connect to your node endpoint and get the latest block number. 
from web3 import Web3

web3 = Web3(Web3.HTTPProvider('YOUR_CHAINSTACK_ENDPOINT'))
print(web3.eth.block_number)
where
  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
  • HOSTNAME — your node HTTPS endpoint hostname
  • USERNAME — your node access username (for password-protected endpoints)
  • PASSWORD — your node access password (for password-protected endpoints)
See also node access details.

​
WebSocket

Use the WebsocketProvider object to connect to your node WSS endpoint and get the latest block number. 
from web3 import Web3

web3 = Web3(Web3.WebsocketProvider('YOUR_CHAINSTACK_ENDPOINT'))
print(web3.eth.block_number)
where
  • YOUR_CHAINSTACK_ENDPOINT — your node WSS endpoint protected either with the key or password
  • HOSTNAME — your node WSS endpoint hostname
  • USERNAME — your node access username (for password-protected endpoints)
  • PASSWORD — your node access password (for password-protected endpoints)
See also WebSocket connection to an EVM node.

​
ethers.js

Build DApps using ethers.js and Ronin nodes deployed with Chainstack.
  1. Install ethers.js.
  2. Connect over HTTP or WebSocket. See also EVM node connection: HTTP vs WebSocket.

​
HTTP

Use the JsonRpcProvider object to connect to your node endpoint and get the latest block number: 
const { ethers } = require("ethers");

var urlInfo = {
    url: 'YOUR_CHAINSTACK_ENDPOINT'
};
var provider = new ethers.providers.JsonRpcProvider(urlInfo, NETWORK_ID);

provider.getBlockNumber().then(console.log);
where
  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password
  • USERNAME — your node access username (for password-protected endpoints)
  • PASSWORD — your node access password (for password-protected endpoints)
  • NETWORK_ID — Ronin network ID:
    • Ronin Mainnet: 2020
    • Saigon Testnet: 2021
See also node access details.

​
WebSocket

Use the WebSocketProvider object to connect to your node WSS endpoint and get the latest block number: 
const { ethers } = require("ethers");

const provider = new ethers.providers.WebSocketProvider('YOUR_CHAINSTACK_ENDPOINT', NETWORK_ID);

provider.getBlockNumber().then(console.log);
where
  • YOUR_CHAINSTACK_ENDPOINT — your node WSS endpoint endpoint protected either with the key or password
  • NETWORK_ID — Ronin network ID:
    • Ronin Mainnet: 2020
    • Saigon Testnet: 2021
