IBM selected DFNS as the core technology for IBM Digital Asset Haven, their new offering for banks, governments, and enterprises managing tokenized assets across all blockchains.

With IBM Digital Asset Haven supported by DFNS, our clients have access to a unified platform that delivers the resilience and data governance they have been asking for, empowering governments and enterprises to build the next generation of financial services.

Coinsub is building payment infrastructure for users who have never touched crypto. That means creating a UX they trust, while still being able to interact with everything on the market.

DFNS was the only platform that could deliver both. The API is robust and deeply configurable, the team is genuinely responsive, and we've shipped dozens of applications on top of it, for businesses and for end users.

Apex built a digital banking platform for the asset management and corporate sector that is simple, fast, and flexible.

Apex's collaboration with DFNS provided our users with secure and user-friendly access to valuable tokenized assets and money market funds. DFNS was the first to introduce biometric authentication for wallets, setting new standards for security and ease of use in digital assets. Their drive to innovate matches ours.
