Custody and Asset Protection
Secure, UK-ready digital asset custody your customers can trust.
What is custody and asset protection?
Custody & Asset Protection is the Zumo Platform’s digital asset safeguarding layer, combining MPC-based storage, segregated wallet infrastructure and proprietary custodial wallet orchestration and ledger management for real-time balance and movement visibility.
This technology element underpins the custody model used in our Crypto Access solution and generates the holdings and transaction data required for digital-asset emissions measurement in Oxygen.
Whether you’re launching a crypto buy, sell, and hold product, adding secure asset storage to an existing service, or preparing for FCA-aligned custody expectations, Zumo gives you a production-ready way to safeguard customer assets, without the cost, risk, or complexity of operating custody in-house.
