Proof of reserves methodology and security measures

Binance exchange’s proof of reserves mechanism is based on Merkle Tree verification to enable users to verify independently that their assets are part of the exchange’s reported amounts. The process involves generating cryptographic proofs that attest to customer funds being present in the exchange wallets without exposing sensitive user data.

For the April 1 snapshot, Binance continued to have its set verification process in place, which covers both exchange balances and third-party custody arrangements.

The two-custody model is a risk management procedure, with most funds held in exchange-controlled wallets for operational reasons, and reserves held with trusted third-party custodians.

The report indicates disparate distributions between exchange balances and third-party custody by asset. For Bitcoin, around 97.9% of reserves are on the exchange directly, and just 2.1% are in third-party custody. The same holds for ETH (96.7% on exchange) and BNB (99.9% on exchange).

Certain assets exhibit more substantial holdings in third-party custody. In the case of PEPE, for instance, customer balances total over 94 trillion tokens while 176 trillion tokens are in third-party custody.
