KuCoin x Cactus Custody: Off-Exchange Solution
Última atualização: 06/11/2025
Dear KuCoin Client,
We’re pleased to announce that KuCoin has integrated with the Cactus Off-Exchange Solution, combining third-party custodial services with secure off-exchange trading infrastructure.
Through this integration, institutional clients can now establish a dedicated Custodian Sub-Account under their KuCoin main account. Each Custodian Sub-Account is directly linked (1:1) to the client’s Cactus account, ensuring transparent and verifiable asset delegation.
Clients can seamlessly perform deposits and withdrawals using Cactus delegation / non-delegation functions, maintaining custody control while accessing KuCoin’s deep liquidity and trading services.

Trading under this setup is designed to settle automatically every 4 hours. KuCoin will handle all settlements directly with Cactus, so no additional action is required from the client side.
Benefits of using the Off-Exchange Settlement (OES) service:
Secure third-party custody
Reduced counterparty risk
Lower costs from minimized deposits and withdrawals across exchanges
Faster fund movements between exchanges for efficient arbitrage
Additional Privileges from KuCoin:
Free colocation services for API traders
New users enjoy VIP Level 12 benefits for the first 60 days
