Open Source in Finance Forum London 2026

FDC3 has become the industry standard for enabling applications on the financial desktop to work together — allowing traders, analysts and operations teams to move seamlessly between tools without re-keying data or stitching together bespoke integrations. The standard defines common APIs, intents and data formats so applications can interoperate in a plug-and-play fashion across any platform.

But as FDC3 adoption grows, the next challenge isn’t just interoperability: it’s trust.

In this session, Kris West and co will take you inside the FDC3 3.0 evolution, exploring the architectural changes that make the standard ready for modern enterprise environments.

Expect a fast-paced tour of the technologies shaping the next generation of financial desktop platforms, including:

- Richer metadata models
- Application and user identity and trust frameworks
- Zero-trust architectures for desktop interoperability
- FDC3 Sail
- New branding and acronym for FDC3!
