I have an existing Web3-based crowdfunding platform built with React (Vite), Node.js, MongoDB, and Ethereum smart contracts. The platform is already implemented and functional, but it contains specific technical bugs that must be fixed to make the system stable and production-ready.
Important: This is a bug-fixing and stabilization project only. No new features, no refactoring, and no redesign are requested. The selected freelancer will work strictly within the existing architecture and codebase.
- MetaMask Connection State Bug Wallet connects successfully, but after page refresh or route change the frontend loses the wallet state while MetaMask remains connected, causing inconsistent UI behavior.
Transaction Feedback Bug ETH transactions are sent to the blockchain, but the frontend does not reliably display success or failure status, leaving the UI stuck in a loading state.
Smart Contract Revert Handling Bug When a contract call fails (revert, gas issue, or invalid input), the error is not properly captured or surfaced to the user, making debugging and user recovery impossible.
- Deliverables
Fully fixed bugs listed above
Verified working flows (wallet → transaction → UI update)
Short technical summary explaining:

- Freelancer Requirements

Hands-on knowledge of Ethereum & MetaMask behavior
Ability to debug Ethers.js / smart contract interactions
