For my Staking pool contract, I am also seeking a Solidity developer. It is not necessary to implement ERC20 tokens from scratch, just paste the ERC20 token state. I need an expert, so please don't contact me if you don't be one. Being an expert and not a ChatGPT user, you should know well. Please don't waste your time or mine if you send me the code and there is a single issue I will charge back and leaving you a bad review on your profile. If you haven't verified your account on Upwork, don't text. No need to talk about 30 hours or anything like that since this is a single file that can be done in a day.
