Am still new to smart contracts and I need help with how to create an ERC20 token swap contract. iI had already created Token A. but after distribution to users we decided to create a new Token B. Am looking for help on a smart contract that can automatically swap old token for the new one at an exchnage rate of 1000:1 with ability to be able to exempt few wallets from been able to swap. i look forward to the help
