    My previous developer created a decentralized exchange, however it is having errors and I need it fixed to make sure it is 100% functional. The site works but it keeps getting errors and people cannot withdraw/deposit/trade half the time and getting errors on the exchange smart contract. I need someone to fix it so it is 100% functional.
