Building a dApp? You need to connect your React frontend to smart contracts. This tutorial covers the complete setup using ethers.js v6 with TypeScript.

Setup

npm install ethers@6 typescript @types/react

Connect to Provider

import { BrowserProvider, Contract } from 'ethers';

async function connectContract() {
  const provider = new BrowserProvider(window.ethereum);
  const signer = await provider.getSigner();
  const contract = new Contract(
    "0xYourContractAddress",
    ABI,
    signer
  );
  return contract;
}

Read Contract Data

const balance = await contract.balanceOf(walletAddress);
console.log(formatUnits(balance, 18));

Use CryptoBoss API alongside your dApp for real-time price data and gas estimates.
