Crypto Exchanges Embrace Proof of Reserves to Rebuild Trust

FTX’s bankruptcy filing in November 2022 exposed the risks of opaque exchange finances, inadequate liquidity controls and the potential misuse of customer assets, triggering a broad crisis of confidence across crypto markets. Proof of Reserves emerged as a key industry response, using on-chain wallet data and tools such as Merkle trees to let customers verify that an exchange holds assets intended to cover their deposits.

Exchanges including Binance and Kraken have continued publishing reserve disclosures, often asserting that customer assets are backed at least 1:1. The measures are designed to improve transparency and reassure users that funds remain available. However, a reserve snapshot may not fully disclose liabilities, borrowing or exposure to affiliated companies, limiting its value as a measure of solvency. Proof of Reserves therefore remains a supplement to independent audits and regulatory oversight, rather than a substitute for them.
