FAQ

What is Proof of Reserves?
A Proof of Reserves (PoR) is an independent audit conducted by a third party which seeks to ensure that on-chain assets of Crypto Exchange match to deposits of its clients. This auditor takes an anonymized snapshot of all balances held and aggregates them into a hash tree — a privacy-friendly data structure that encapsulates all client balances. Here is a sample PoR audit report by Hacken.

What projects need a PoR audit?
