Provably fair isnt suit out for exchange yet this would rather be seen on gambling online sites,maybe you do mean about Legitimate exchange sites?
Only stick out on the current top tier or best ones as of this moment.You can eventually check it out on CMC itself on which exchange is worth to use on.
Maybe what he meant is that an exchange that offers a fair service, etc. OP, if you wanted a trusted exchange sites and apps why not try popular exchanges like BNB, Coinbase and other? You can always compare the fees of each exchanges. Here are some of the list it may help you somehow.

Yeah, provably fair is used by gambling sites. But anyway, the OP more than likely meant the legitimacy or authenticity of an exchange. And how competitive their fees - withdrawal/trading fees among other exchanges?
