Crypto exchanges have realized they must introduce the Merkle tree proof of funds.
The discussion accelerated after the FTX collapse. However, other failures in the industry have also contributed to highlighting the need for this in the crypto industry. Some of these failures are Celsius Network, BlockFi, Voyager, Three Arrows Capital, Alleged and last FTX.
Crypto Exchanges with Merkle Tree Proof of funds
Gate.io was the first crypto exchange implementing a 3rd party auditor for proof of funds.
Nexo was the first crypto lending platform to hire a 3rd party auditor for full transparency regarding proof-of-reserves.
After, they have pushing other crypto-related companies to do the same and Kraken did follow in August 2022. However, after the FTX collapse in November 2022 the topic is superhot and almost all major crypto exchanges are doing statements about implementing the Merkle tree proof-of-reserves ASAP.
What is a Merkle Tree?

What is Proof of reserves?
No formally accepted rules or procedures define crypto proof of reserves audit.
Still, in general, a Proof of Reserves (PoR) is an independent audit conducted by a third party.
The primary mission of the 3rd party in this contest is to ensure that a custodian holds the assets it claims on behalf of its clients.
This auditor takes an anonymized snapshot of all balances held and aggregates them into a Merkle tree — a privacy-friendly data structure that encapsulates all client balances.
From there, the auditor obtains a Merkle root: a cryptographic fingerprint that uniquely identifies the combination of these balances when the snapshot was created.
