Web3 & DApp Development
Wallet-native apps with secure on-chain interactions.
100%
Signed tx clarity
Prod
Mainnet-ready flows
Secure
Wallet-first auth
Overview
Web3 development bridges familiar web UX with blockchain infrastructure — wallet authentication, contract reads/writes, and transparent on-chain state for users who may not be crypto-native.
I have integrated Ethereum wallet connectivity and smart contract interactions using Web3.js and Ethers.js in production DApps, handling connection states, network switches, and transaction feedback carefully.
Security and clarity come first: users always know what they sign, what failed, and what succeeded — with fallbacks when RPC nodes or wallets misbehave.
What's included
Wallet integration
MetaMask, WalletConnect patterns, session persistence, and network validation.
Smart contract layer
Read/write contract methods, event listeners, and ABI-driven UI generation.
DApp frontend
Next.js interfaces that feel like modern SaaS — not clunky 2021 crypto UIs.
Transaction UX
Pending states, gas estimation messaging, error recovery, and receipt history.
Deliverables
- Wallet-connected web application
- Contract integration module
