Citi Unveils CIDAP Middleware Platform for Digital Assets at Sibos 2025

At Sibos 2025, held September 29 through October 2 in Frankfurt, Citi showcased its Integrated Digital Asset Platform (CIDAP) as a middleware layer designed to unify tokenization, digital custody, and blockchain connectivity services. CIDAP functions as banking-as-a-platform infrastructure, enabling institutional clients to integrate digital asset capabilities into their existing workflows through reusable components. The platform is designed to support multiple blockchain networks and digital asset types, providing interoperability across the fragmented digital asset ecosystem.

By building CIDAP as middleware rather than a standalone product, Citi is enabling other financial institutions and fintechs to embed digital asset services within their own platforms. Financial terms and specific launch timelines for general availability were not disclosed. The announcement reflects the broader trend of major banks building platform-layer infrastructure to serve as the backbone for embedded finance in digital assets, potentially reshaping how institutional clients access tokenization and custody services.
