Blockchain #Developers often interact with RPC nodes for data retrieval and transaction execution. This article highlights three top tools simplifying these interactions: Tatum, Infura, and Alchemy. In some cases you need to obtain API key first to get started. I recommend to visit documentation for each tool to learn more.
1️⃣ Tatum.io - JavaScript SDK
Tatum SDK simplifies #BlockchainDevelopment across more than 90 blockchains.
You can easily install via NPM:
npm install @tatumio/tatum
👨💻Code Snippet to get Wallet Balance:
import { Tatum } from '@tatumio/tatum';
async function getWalletBalance(apiKey, walletAddress, chain) {
return await Tatum.getBalance(apiKey, walletAddress, chain);
}
2️⃣ Infura.io
Infura provides easy access to Ethereum and IPFS networks.
👨💻Code Snippet to get Wallet Balance:
const Web3 = require('web3');
const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/v3/YOUR_API_KEY'));
async function getBalance(walletAddress) {
return await web3.eth.getBalance(walletAddress);
}
3️⃣ Alchemy.com
Alchemy offers tools for #Ethereum, #Polygon, and other blockchains.
👨💻Code Snippet to get Wallet Balance:
const { createAlchemyWeb3 } = require("@alch/alchemy-web3");
const web3 = createAlchemyWeb3("https://eth-mainnet.alchemyapi.io/v2/YOUR_API_KEY");
async function getBalance(walletAddress) {
return await web3.eth.getBalance(walletAddress);
}
📖 Conclusion:
Tatum SDK, Infura, and Alchemy provide robust solutions for interacting with blockchain RPC nodes, each with unique features and strengths. These tools are indispensable for efficient blockchain application development.
