tronweb

What is tronweb?

TronWeb is a JavaScript library that provides a comprehensive set of tools for interacting with the TRON blockchain. It allows developers to create, deploy, and interact with smart contracts, manage accounts, and perform transactions on the TRON network.

What are tronweb's main functionalities?

Account Management

This feature allows you to manage TRON accounts, including retrieving account information such as balance and transaction history. The code sample demonstrates how to initialize TronWeb and fetch account details using an address.

const TronWeb = require('tronweb');
const tronWeb = new TronWeb({
  fullHost: 'https://api.trongrid.io',
  privateKey: 'your_private_key'
});

async function getAccountInfo(address) {
  const accountInfo = await tronWeb.trx.getAccount(address);
  console.log(accountInfo);
}

getAccountInfo('your_tron_address');

Smart Contract Interaction

TronWeb allows you to interact with smart contracts on the TRON network. This code sample shows how to call a method on a deployed smart contract by specifying the contract address, method name, and parameters.

const TronWeb = require('tronweb');
const tronWeb = new TronWeb({
  fullHost: 'https://api.trongrid.io',
  privateKey: 'your_private_key'
});

async function callContractMethod(contractAddress, methodName, parameters) {
  const contract = await tronWeb.contract().at(contractAddress);
  const result = await contract[methodName](...parameters).call();
  console.log(result);
}

callContractMethod('contract_address', 'methodName', ['param1', 'param2']);

Transaction Management

This feature enables you to manage transactions on the TRON network, including sending TRX tokens. The code sample demonstrates how to send a transaction to a specified address with a given amount.

const TronWeb = require('tronweb');
const tronWeb = new TronWeb({
  fullHost: 'https://api.trongrid.io',
  privateKey: 'your_private_key'
});

async function sendTransaction(to, amount) {
  const transaction = await tronWeb.trx.sendTransaction(to, amount);
  console.log(transaction);
}

sendTransaction('recipient_address', 1000);

web3

Web3.js is a popular JavaScript library for interacting with the Ethereum blockchain. It provides similar functionalities to TronWeb, such as account management, smart contract interaction, and transaction handling, but is specifically designed for Ethereum. While TronWeb is tailored for the TRON network, Web3.js is the go-to library for Ethereum developers.

ethers

Ethers.js is another JavaScript library for Ethereum, offering a more lightweight and modular approach compared to Web3.js. It provides similar functionalities to TronWeb but focuses on Ethereum. Ethers.js is known for its simplicity and ease of use, making it a popular choice among Ethereum developers.
