Crypto exchanges tout cold storage ratios after Binance attack

Coinbase says it keeps more than 99% of customer assets offline, while Gate reports 88.26% of its total assets are kept in cold storage. Crypto exchanges were quick to reassure users following the attack on Binance’s hot wallet infrastructure last week, with several companies disclosing how they divide assets between cold storage and internet-connected hot wallets this week. Crypto exchange Gate on Thursday launched a “Proof of Security” (PoSEC) framework, reporting that 88.26% of its total assets were in cold storage and 11.74% in hot wallets.
