美股存储概念股盘前走弱，西部数据跌2.3%

Coinbase published a post detailing its user asset protection mechanisms, stating it was not impacted by Binance’s earlier hot wallet security incident, and that its platform systems and user funds remain unharmed. The exchange noted that over 99% of user assets are held in cold wallets, with only a small portion in hot wallets to cover daily user withdrawals and usage needs, and balances are dynamically adjusted based on deposit and withdrawal demands. All institutional custody vault assets are cold-stored and isolated on-chain. For fund transfer security, Coinbase employs distributed key protection, withdrawal limits, abnormal activity monitoring, and emergency stop mechanisms. Cold wallet private keys are split for storage and never fully reconstructed during the signing process; the key signing service in hot wallet production environments also prohibits individual independent access. If abnormal transactions or surging withdrawal volumes are detected, the system initiates investigations and imposes limits, and can suspend partial or full fund transfers by disabling signing keys when necessary. Coinbase also emphasized that user assets are always held by users, with the platform maintaining a 1:1 asset reserve, and will not lend or misappropriate assets without user consent. As of September 30, 2026, Coinbase’s platform asset size reached $377 billion, holding $8.6 billion in cash and cash equivalents, and $2.2 billion in investment-grade crypto assets. The company added that as AI capability development reshapes the security risk landscape, it will continue to increase investment in security technologies.
