CZ Recalls $15 Billion Withdrawal Test as Binance Faced Market Panic in 2022

Changpeng Zhao (CZ), founder and former CEO of Binance, outlined how the exchange safeguards user funds during periods of extreme market volatility during a recent AMA session on Binance Square.Responding to questions about user protection during market turmoil, CZ emphasized that Binance operates as a fully reserved exchange supported by transparent, auditable systems.“Binance has proof of reserves. We are fully reserved,” CZ said. “Balances are audited, and everything is easy to track.”Proof of Reserves and Transparency at the CoreCZ highlighted transparency as one of Binance’s defining principles, noting that the exchange’s on-chain proof-of-reserves framework allows users and analysts to verify holdings independently.“We are the best in transparency,” he said, adding that public blockchain infrastructure makes asset tracking significantly easier compared with traditional financial systems.Proof of reserves became a central focus across the crypto industry following a series of exchange failures, increasing user demand for verifiable custody models.December 2022: A Major Stress Test for BinanceCZ referenced December 2022 as a critical moment that tested Binance’s infrastructure and liquidity resilience.During that period, Binance processed more than $15 billion in withdrawals within a single week, while the exchange’s total reserves stood at approximately $16 billion at the time.At the peak of market stress, CZ said Binance handled around $7 billion in withdrawals in a single day without disruption.“These were real stress tests,” he said.‘As Long as the System Is Working, It’s Working’CZ recalled that during the height of the withdrawal surge, he remained calm due to confidence in Binance’s reserve model and technical systems.“I remember that time very clearly,” he said. “I was still managing Binance. I was having dinner with friends, and they asked why I wasn’t busy.”His response, he explained, was simple: as long as systems function properly, operations continue normally.“As long as the system is working, it is working,” CZ said.
