Simple Web3 Project is a JavaScript library that provides a simple interface for interacting with the Ethereum blockchain using Web3.js.
- Fetch the latest block number on the Ethereum blockchain.
- Get the balance of an Ethereum address.
- Call methods of Ethereum smart contracts.
You can install Simple Web3 Project via npm:
npm install cryptopunkstarconst SimpleWeb3Project = require('cryptopunkstar-eth');
// Create an instance with your preferred Ethereum node endpoint const web3Project = new SimpleWeb3Project('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
// Get the latest block number web3Project.getBlockNumber() .then(blockNumber => { console.log('Latest block number:', blockNumber); }) .catch(error => { console.error('Error:', error); });
// Get the balance of an Ethereum address const address = '0x1234..........................333'; // Replace with the desired address web3Project.getBalance(address) .then(balance => { console.log('Balance:', balance, 'ETH'); }) .catch(error => { console.error('Error:', error); });
// Call a method of a smart contract const contractAddress = '0x1234..........................333'; // Replace with the contract address const abi = []; // Replace with the contract ABI const methodName = 'methodName'; // Replace with the method name const methodParams = []; // Replace with method parameters web3Project.callContractMethod(contractAddress, abi, methodName, methodParams) .then(result => { console.log('Result:', result); }) .catch(error => { console.error('Error:', error); });
Replace 'https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID' with your actual Infura project ID.
Replace '0x1234..........................333', [], and 'methodName' with the actual contract address, ABI, method name, and method parameters respectively.
