I have ERC20 compatible token that is already deployed in the ethereum main-net. I have a requirement to accept these tokens as payment, And this is going to be a new contract, The below are my doubts.
Can I use another ERC20 contract to do this functionality, As I read in some blogs it tells we won't be able track the details of transfer. If it's not the case, Someone please provide me with a sample contract or documents.
I saw some solutions using the ERC223 contract, If that the case can I use my already existing ERC20 tokens to use in the newly created ERC223 token contract..? if available please give a sample contract.
