## Key points

- Coinbase says over 99% of customer crypto is held offline.
- Multiple controls are intended to slow or stop suspicious transfers.
- Binance’s reported $6.4 billion hack has heightened industry scrutiny.

## Summary

Coinbase says more than 99% of customer crypto is kept in offline cold storage, after a major hack at rival exchange Binance raised questions about security. The exchange says its layered controls are designed to limit how quickly funds can move online and to prevent a single compromised employee account from authorising transfers.

Cold-wallet keys are split into pieces, unusual withdrawal surges are reviewed by staff, and Coinbase can take signing keys offline. It says customer assets are held one-for-one and are not lent out without customers’ direction; as of 30 September, it reported $8.6 billion in cash and equivalents and $377 billion in assets on its platform. Binance lost about $6.4 billion, while Coinbase has also recently disclosed separate incidents involving customer data, though neither affected customer funds.
