Institutional-grade custody

We are a Swiss-regulated bank, which means that we follow the highest regulatory, certification, compliance and tech standards to protect your digital assets. Digital asset transactions conducted with Sygnum are always screened by our proprietary Crypto-AML tool to ensure AML/KYC compliance.

Institutional-grade custody

Certifications and compliance

Our multi-custody platform for your digital assets is certified and audited in accordance with ISAE 3000 and ISAE 3402 industry standards, protected by FIPS-140.2 Level 3 hardware security modules (HSMs), MPC technology and high-security data centres in Switzerland.

ISAE 3000

The ISAE 3000 report ensures the initial key is generated in a compliant, safe environment to mitigate relevant risks.

ISAE 3402

The ISAE 3402 report ensures the transaction signing environment is safe and includes a control framework and processes to handle client assets securely and mitigate of relevant risks.

FIPS-140.2 level 3 HSMs

FIPS 140-2 is a US government standard for cryptographic module and solution security. Level 3 hardware ensures physical tamper-resistance and identity-based authentication, and a physical or logical separation between interfaces for critical security parameters (CSPs) that enter and leave the module.

High security Swiss data centres

To store sensitive key material, we use Swiss data centres that meet industry leading standards for critical infrastructure (such as Tier IV by the Uptime Institute) for fault tolerance, security and redundancy.

MPC technology

Multi-Party Computation (MPC) is a type of cryptographic technology that removes the single point of failure possible with a private key. By allowing multiple parties to securely sign transactions without any one party being able to see the inputs of the others, MPC adds an additional layer of security.
