Ethereum Smart Contract & Front-End Sync

We have an Ethereum-based blockchain project where the smart contract and front-end are not fully in sync after a recent update. The issue needs to be debugged and resolved so that on-chain data displays correctly in the UI in real time.
Scope of Work:
Smart Contract Debugging
Verify that all contract functions return accurate values.
Check event emissions for missing or delayed triggers.
Front-End Integration Fix (Web3.js / Ethers.js)
Update calls to match the latest ABI.
Ensure transaction status and event logs appear instantly after execution.
Testing
Deploy updated contract (if needed) to a testnet (Goerli or Sepolia).
Test with MetaMask to ensure smooth wallet interaction.
Documentation
Provide a short report detailing the bug, the fix, and replication steps.
Requirements:
Proven experience in Solidity & Ethereum smart contract debugging.
Strong understanding of Web3.js or Ethers.js integration.
Ability to debug event handling and transaction flow.
Familiarity with Hardhat/Truffle and Git workflow.
Timeline:
Approx. 5 hours total, including testing and documentation.
Start immediately upon hiring.
