6 Questions for Kim Hamilton Duffy of Centre

My understanding is that there are two main flows when one wants to swap within a constant product AMM LP:

1. Trader transfers a certain amount of Token X into the LP

2. An equivalent of Token Y is transferred to Trader

Assuming that both Token X and Token Y are ERC-20 compliant, are there any issues if I use transfer() for both Flow 1 and Flow 2? Or, should I actually be using transferFrom() instead?
