Is there a smart contract for buying ether?

hadees

I was wondering if there was a smart contract so that I could buy ether directly from someone for cash or BTC without getting scammed.

I was thinking about writing one for myself but I'm not sure the right way to prove that the other currency has been sent.

not that I am aware of. you need a third party to be able to verify that a transfer has been done
