does anyone know how to listen events on smart contract from another s.c? is it possible?

Events are for off-chain software, on-chain you cannot read those

ok, thanks. how can i get incoming erc20 transfer on contract. can i use it without calling transferFrom()?

If you mean from a contract, transferFrom is the only way if it's an erc20

Using transfer() inside a contract function will move them from the contract itself

ok. thanks, i'll remake entire contract then

this is the way

reply here if you have more info, those can help others
