Integrate MetaMask, Web3, Ethers, and Smart Contracts into Your dApp

Service Description

professional React Web3 frontend development services. I specialize in building decentralized application (dApp) frontends with modern, responsive UI and seamless blockchain integration. With 2+ years of experience working with startups, software houses, and SMBs, I deliver secure, scalable, and production-ready dApp interfaces using React.js, Web3.js, and Ethers.js.

Blockchain Features & Smart Contract Integration

Integrate Ethereum smart contracts and blockchain logic into your React frontend or Vanilla JavaScript dApp:

• NFT Integration (ERC721): Display and interact with non-fungible tokens for marketplaces, digital collectibles, art platforms, and blockchain-based games.

• Fungible Tokens (ERC20 / BEP20): Enable token transfer, staking, and balance fetching in your frontend using Web3.js or Ethers.js.

• Smart Contract Interaction: Connect your frontend to deployed smart contracts on Ethereum, Binance Smart Chain, or Polygon. Read/write blockchain data, trigger events, and fetch transaction history.

Wallet Integration Services

Improve user accessibility by implementing crypto wallet connectivity directly in your dApp:

• MetaMask Integration: Allow users to connect, sign transactions, and interact with smart contracts using MetaMask.

• WalletConnect Integration: Add support for mobile wallet access, enabling users to interact with your dApp via QR codes.

• Coinbase Wallet, Crypto.com Wallet, Binance Wallet: Expand access by supporting major wallets through custom integrations or SDKs.

• Network Detection & Switching: Automatically detect blockchain networks (Ethereum, BNB Chain, Polygon) and guide users to switch as needed.
