Digital wallets security solutions

Digital wallets take different forms: custodial or non-custodial cryptocurrency wallets, mobile banking or money transfer applications. They all serve the same function: storing and managing user’s financial assets through apps.

Digital wallets face threats related to secure data storage, authentication and fraud prevention. As a result, they have elevated security requirements by combining financial, banking and privacy regulations with platform (web and mobile) specifics.

Security assessment

We perform digital wallet security assessment and conduct design reviews on existing implementations. We use OWASP (M)ASVS and PCI as a starting point, and then deep dive into specific areas such as data protection, anti fraud, device attestation, API protection, transaction logic flaws, and so on.


We collaborate with your team to set up and improve the SSDLC process for digital wallet development. We assist in prioritising security features, finding appropriate automation tools, and staying up to date with the latest security guidelines and regulations.

Cryptography engineering

Implementing cryptography is hard, especially in digital wallets that interact with blockchain networks. We audit the cryptographic core, identify flaws, recommend fixes, and put in place a more reliable cross-platform cryptographic layer.
