Unfortunately, we used different transfer function name in our smart contract which causes issues for us to list it on some exchange, transfer function name should be
transfer but we used
transferTokens which is not erc20 now :(
I want to ask, to use transfer function so should we extend the old contract somehow or should we deploy new contract on ethereum? Which approach is better? If we need to extend then how can we do it and what are the major issues of contract extend?
