​
/jsonrpc, /wallet, /walletsolidty support

Chainstack supports all three method endpoints:

  • /jsonrpc
  • /wallet
  • /walletsoldity

Note that the TRON nodes provided are full only (non-archive), which makes some of the methods unsupported.

For the full API reference, see the official TRON API Reference.

MetaMask

On node access details, click Add to MetaMask.

​
web3.py

Build DApps using web3.py and TRON 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.

​
TronWeb.js

See TronWeb.

Example of doing a getBalance call:

const { TronWeb } = require('tronweb');

const tronWeb = new TronWeb({
    fullHost: 'YOUR_CHAINSTACK_ENDPOINT'
});

const address = 'TWiEv2wfqQ8FkbAJ6bXt1uA2Uav9ZWvXip';

async function getBalance() {
    try {

        const balanceInSun = await tronWeb.trx.getBalance(address);

        const balanceInTRX = tronWeb.fromSun(balanceInSun);
        
        console.log(`Address: ${address}`);
        console.log(`Balance in SUN: ${balanceInSun}`);
        console.log(`Balance in TRX: ${balanceInTRX}`);
    } catch (error) {
        console.error('Error getting balance:', error);
    }
}

getBalance();

where

  • YOUR_CHAINSTACK_ENDPOINT — your TRON node base endpoint without the /jsonrpc, /wallet, or /walletsolidity postfixes.

​
Hardhat

Configure Hardhat to deploy contracts and interact through your Klaytn 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.

See also Forking EVM-compatible mainnet with Hardhat.

​
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
