Blockchain Mobile App Bug Hunting
Budget: $30 – $250 USD
We're facing small but maddening bugs in our blockchain-powered mobile app—and we need a real developer who can dig deep and fix them for good.
The app is built with React Native and uses Web3.js to connect to Ethereum smart contracts. While most of the features work, there are annoying issues that pop up randomly—wallets not connecting on the first try, transactions hanging or silently failing, and occasional UI freezes when fetching on-chain data. These aren't massive bugs, but they ruin the user experience and are a nightmare to track down.
We're looking for someone who has actually built or debugged a real Web3 app—not someone who’s just read about it.
Your Tasks:
Fix wallet connection issues (especially with Coinbase Wallet and WalletConnect)
Resolve random transaction failures and ensure consistent on-chain communication
Debug inconsistent UI behavior tied to smart contract data
Test on both iOS and Android and ensure a stable, reliable experience
Requirements:
Solid experience with React Native, Web3.js, and Ethereum-based dApps
Deep understanding of mobile debugging, error handling, and transaction lifecycle
Ability to quickly locate the root cause of intermittent bugs and fix them permanently
Bonus if you've worked with WalletConnect, Ethers.js, or mobile crypto wallets
Budget: $30–$250
Timeline: 7 days max
:no_entry_sign: Important: No AI-generated or generic bids and If you haven't debugged this kind of app before, this job is not for you.
How to Apply:
Send 1-2 links to real Web3 mobile projects you’ve worked on. Write 2-3 sentences on how you would fix wallet connection or transaction bugs. We’ll know if it’s real.
