I will fix metamask wallet connection and web3 transaction errors

Is your dApp failing to connect MetaMask, switch networks, estimate gas, or complete a transaction? I will debug the frontend integration and fix the agreed Web3 user flow.

I can help with:

MetaMask connection and account-change issues

Wrong network and chain-switching errors

Contract read and write failures

ABI, contract address, and parameter mismatches

Transaction rejection, gas estimation, and pending-state handling

Wallet event listeners and reconnect behavior

Ethers.js, Web3.js, wagmi, React, and Next.js integrations

Clear loading, success, and error feedback

You will receive focused source-code changes, testing for the agreed flow, and an explanation of the problem and solution.

This service covers Web3 frontend integration and troubleshooting. It does not include a formal smart-contract security audit, recovery of lost funds, access to seed phrases, financial advice, or guaranteed resolution of third-party wallet or RPC outages. Please message me before ordering with your framework, library versions, chain, contract address, public ABI, error message, and reproduction steps.
