Ronin tooling

​

Truffle

Configure Truffle Suite to deploy contracts to your Ronin nodes.

const HDWalletProvider = require("@truffle/hdwallet-provider");
const mnemonic = 'pattern enroll upgrade ...';
...
module.exports = {
 networks: {
    chainstack: {
        provider: () => new HDWalletProvider(mnemonic, "YOUR_CHAINSTACK_ENDPOINT"),
        network_id: "*"
    },
   }
  }
};

​

web3.js

Build DApps using web3.js and Ronin nodes deployed with Chainstack.

​

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.

​

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.blockNumber)

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.blockNumber)

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.

​

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
