When private key permissions are changed in Hong Kong virtual asset custody, how should the approval process and logs be stored?
When private key permissions are changed in Hong Kong virtual asset custody, approval and logs should be saved according to customer asset control events: first record the reason for the change, wallet or address range, permission type and affected customers, then retain the records of initiation, review, approval, execution, rollback and closure, and at the same time save system logs, administrator logs, on-chain hashes, permission matrix version and reconciliation results before and after the change.
