Fix Ethereum Smart Contract Bugs

I’m running a small dApp on Ethereum that connects through the wagmi.sh library. A recent update introduced smart-contract bugs—functions are reverting and expected events never fire—so the app is effectively stuck.

I need a Solidity-savvy developer who can jump in right away, locate the root cause, patch it, and redeploy a clean contract without breaking the existing wagmi.sh front-end integration.

Key tasks
• Audit the current Solidity codebase in my GitHub repo
• Isolate the bug and propose the safest fix
• Update tests (Hardhat) and prove the fix on a public testnet
• Supply the patched contract, migration script, and a concise changelog

Turnaround is ASAP. If you can pinpoint and resolve issues quickly, please reach out with your estimated timeframe for completion.
