Institutional security and control

Sygnum’s custody platform supports more than 70 digital assets and ensures they remain your property at all times through an off-balance sheet, ring-fenced structure. Our security model combines FIPS-140.2 Level 3 hardware, Multi-Party Computation and Swiss-based Tier IV data centres. All transactions are screened through Sygnum’s Crypto-AML system. As a regulated Swiss bank, we provide audited controls and access to trading and staking through a single integrated platform.

Regulated, compliant custody

Our certified custody environment delivers secure key generation and strong operational controls under ISAE 3000 and ISAE 3402. Every transaction is screened through Sygnum’s Crypto-AML system to support continuous compliance. Assets are protected with FIPS-140.2 Level 3 hardware and Tier IV Swiss data centres to support operational resilience and security.

Full ownership protection

Client assets are held off-balance sheet within a ring-fenced structure designed to support client asset segregation from Sygnum’s assets. We avoid third-party custodians to limit counterparty exposure and provide a direct custody setup with defined operational controls.
