Case Study: SWIFT achieves cross-border CBDC interoperability with Kaleido

Sibos demonstrates cross-border CBDC interoperability across 18 banks with Kaleido

The customer, Sibos, faced the challenge of digital islands emerging from the proliferation of incompatible national CBDC systems. They needed to prove that a single gateway could connect diverse domestic CBDC networks and existing payment rails for seamless cross-border transactions. Vendor Kaleido served as the core technology provider for this initiative.

Kaleido delivered full-stack infrastructure, including the CBDC platform, middleware, and blockchain networks, featuring a unified CBDC gateway. The solution successfully demonstrated CBDC-to-CBDC flows between Ethereum Quorum and R3 Corda networks and fiat-to-CBDC transactions with an RTGS system. As a result, Kaleido helped validate a cross-border gateway model for 18 participating banks, proving multiple domestic CBDC systems could interconnect through a single gateway.
