Review of Coinbase Cold Storage and Exchange Security
Start here
AI-assisted source synthesis · not an independent investigation.
On November 5, 2026, Coinbase stated that more than 99% of customer assets are held in cold storage, while its dedicated Custody vault provides 100% cold storage and on-chain segregation. The report placed this disclosure against the backdrop of heightened scrutiny of exchange security following Binance’s $6.3 billion attack on October 29, while also noting that cold storage alone cannot prevent stolen credentials or compromised systems from approving fraudulent transfers; security measures must also cover independent approvals, separation of permissions, and continuous oversight. A survey showed that among 351 institutional investors, 66% ranked security and key signing as priorities when choosing a custodian, up from 8% in 2025.
