​
/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.

​
WebSocket event subscription not available

TRON nodes currently do not support WebSocket connections for event subscriptions. If you need to subscribe to events, please vote and follow the feature request at TRON event plugin support.

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
