MetaMask

On node access details, click Add to MetaMask.

​
web3.py

Build DApps using web3.py and Sonic nodes deployed with Chainstack.

  1. Install web3.py.
  2. Connect over HTTP. 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

See also node access details.

​
ethers.js

Build DApps using ethers.js and Sonic nodes deployed with Chainstack.

  1. Install ethers.js.
  2. Connect over HTTP. 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.JsonRpcProvider(urlInfo.url, NETWORK_ID);

provider.getBlockNumber().then(console.log);

where

  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password

  • NETWORK_ID — Sonic network ID:

    • Mainnet: 146
    • Blaze Testnet: 57054

See also node access details.

​
Hardhat

Configure Hardhat to deploy contracts and interact through your Sonic nodes.

  1. Install Hardhat and create a project.

  2. Create a new environment in hardhat.config.js:

    require("@nomiclabs/hardhat-waffle");
...
module.exports = {
  solidity: "0.7.3",
  networks: {
    chainstack: {
        url: "YOUR_CHAINSTACK_ENDPOINT",
        accounts: ["YOUR_PRIVATE_KEY"]
    },
  }
};

    where

    • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS or WSS endpoint protected either with the key or password. See node access details.
    • YOUR_PRIVATE_KEY — the private key of the account that you use to deploy the contract

  3. Run npx hardhat run scripts/deploy.js --network chainstack and Hardhat will deploy using Chainstack.

​
Remix IDE

To make Remix IDE interact with the network through a Chainstack node:

  1. Get MetaMask and set it to interact through a Chainstack node. See Interacting through MetaMask.
  2. In Remix IDE, navigate to the Deploy tab. Select Injected Provider - MetaMask in Environment.

This will engage MetaMask and make Remix IDE interact with the network through a Chainstack node.

​
Foundry

  1. Install Foundry.
  2. Use --rpc-url to run the operation through your Chainstack node.

​
Forge

Use forge to develop, test, and deploy your smart contracts.

To deploy a contract:

forge create CONTRACT_NAME --contracts CONTRACT_PATH --private-key YOUR_PRIVATE_KEY --rpc-url YOUR_CHAINSTACK_ENDPOINT

where

  • CONTRACT_NAME — name of the contract in the Solidity source code
  • CONTRACT_PATH — path to your smart contract
  • YOUR_PRIVATE_KEY — the private key to your funded account that you will use to deploy the contract
  • YOUR_CHAINSTACK_ENDPOINT — your node HTTPS endpoint protected either with the key or password

​
Cast

Use cast to interact with the network and the deployed contracts.

To get the latest block number:

cast block-number --rpc-url YOUR_CHAINSTACK_ENDPOINT

where YOUR_CHAINSTACK_ENDPOINT is your node HTTPS endpoint protected either with the key or password
