"Deribit hot wallet compromised, but client funds are safe and loss is covered by company reserves," Deribit tweeted. "Our hot wallet was hacked for USD 28m earlier this evening just before midnight UTC on 1 November 2022."
The company said it is performing ongoing security checks and has halted withdrawals — including withdrawals from third-party custodians Copper, Clearloop and Cobo — until it is confident that the platform is safe to re-open.
