Edit Backend for Crypto Transactions
Budget: $30 – $250 USD
I’m looking for a seasoned full-stack developer with proven blockchain expertise to jump into my existing codebase and fix the back-end layer that powers our cryptocurrency transactions. The front-end is stable; the problems surface server-side where transactions are built, signed, and broadcast.
Here’s what I need from you:
• Diagnose the current back-end logic and pinpoint why certain transactions fail or hang.
• Refactor or rewrite the affected modules so every payment, transfer, and balance query completes successfully on both testnet and mainnet.
• Add clear inline comments and a brief README update describing your changes so I can maintain them later.
• Commit the working code to my private repo and run a short hand-over call to ensure I can replicate your results.
Acceptance criteria:
• End-to-end wallet transaction succeeds with no errors.
• Existing API endpoints remain unchanged for the front-end.
• All automated tests (or the new ones you add) pass.
I need this turned around ASAP, so let me know how quickly you can dive in and your estimated completion time. If you have a track record integrating cryptocurrency transactions at scale, I’m ready to start right away.
