Hot wallet architecture on OKX OKX's hot wallet system uses multiple technical solutions, including online and semi-offline risk-management systems, semi-offline multisignature services, big data risk-management systems and other protection mechanisms to ensure the security of private keys. All user-asset deposit and withdrawal processes need to be verified by multiple risk-management mechanisms before being broadcast to the blockchain for confirmation.
The ciphertext is stored in a semi-offline signature device and held by three different private key holders. All three private key holders must not be in the same country simultaneously. Private key backup - Each private key has a backup.
Even if the space is physically attacked or the device is stolen, the private key cannot be compromised. Conditions to enable the backup private key - If any private key holder has a personal accident that potentially results in the permanent loss of the private key, including death or amnesia, we will enable the backup private key within 48 hours. Then, we will update the private key file stored in the physical device and choose a new private key holder.
For transactions that are being deposited into OKX, the Online Risk-Management System then checks the validity of the funds, as well as deposit frequency and amount. It also checks for abnormalities in profits and account behavior. The withdrawal transactions that pass the above checks of the Online Risk-Management System will be sent to the Vault System.
This system then automatically creates an unsigned transaction. This transaction is then sent to the Signature Task and passed to the semi-offline multisig stage via a special network communication protocol for signatures. We define this communication as a semi-offline signature service, in which it is practically impossible for an attacker to obtain the private key on a semi-offline server via an online attack.
On the other hand, the semi-offline servers cannot be compromised, even if they are physically attacked, as the private key is stored in the server's RAM — making it impossible for hackers to access. OKX's hot wallet system also has a second layer of risk management: semi-offline risk management.
