Ask HN: Who Key for Exchange Wallet?

[vrdvn]

Big exchanges like Coinbase have centralised exchange wallets with billions of dollars, who/how many people know the private key, how do they prevent rouge employee emptying the main account?

[wmf]

No employees have direct access. The private keys should be in HSMs that have automated spending policies that require multiple approvals, etc.

[vrdvn]

Intresting, not even the CEO of the company?

[wmf]

No.
