About this Gig

Is your Web3 dApp broken, wallet connection failing, or smart contract interaction not working as expected?


I will troubleshoot and fix Web3 dApp issues involving MetaMask, WalletConnect, smart contracts, blockchain APIs, transaction flows, and frontend integrations.


I can help with:

  • MetaMask and WalletConnect errors
  • Smart contract integration issues
  • Failed or stuck transactions
  • Wrong network and chain switching problems
  • React / Next.js Web3 bugs
  • Wallet balance and account display issues
  • Contract read and write failures
  • RPC and blockchain API errors
  • dApp frontend integration problems
  • DeFi, NFT, DAO, and token dApp fixes
  • Existing Web3 code troubleshooting
  • Transaction status and confirmation issues


I work with EVM-compatible networks including Ethereum, Base, Polygon, BNB Chain, Arbitrum, and others.


Already have an existing dApp that is not working correctly? Send the error, project details, contract address, ABI, and network information.


Message me before ordering for complex Web3 issues.
