Ethereum Wallet Integration for Crypto Transactions

I’m building a service that handles live cryptocurrency transactions on the Ethereum network and need a developer to wire in secure, reliable wallet integration as the first milestone.

The job centres on connecting my front end to users’ Ethereum wallets (MetaMask, WalletConnect or similar) so they can send, receive and view balances in real time. Gas-efficient coding, clear error handling and protection against common attack vectors (re-entrancy, replay, phishing pop-ups) are must-haves. You should be comfortable working with Web3.js or Ethers.js, Solidity where needed, and standard test networks before main-net deployment.

Deliverables
• Deployable wallet-integration module hooked to Ethereum main-net and Goerli test-net
• Clean, commented code plus brief setup/read-me so another dev can extend it
• Short video or screenshots proving successful connect, send and receive flows

Acceptance criteria: connection succeeds in modern browsers, transactions propagate within expected block times, and no critical findings appear in the final MythX or Slither scan.
