In brief
- The design split a cross-border transfer into two domestic payments.
- Coordination between the payments was central to managing settlement risk.
The development
Project Icebreaker’s March 2023 report examined a hub-and-spoke approach to connecting retail CBDC systems. In its design, a cross-border transfer becomes two payments within separate domestic systems. Foreign-exchange providers buy one currency and sell another, while coordinated settlement links the two sides. The digital currency itself therefore does not need to circulate outside its home system.
Why it matters
This offers a useful way to think about interoperability: separate networks can coordinate without becoming one ledger. The report explored simplicity, competition and transparency as potential advantages. Those are design aims rather than guaranteed outcomes for remittance customers. A technical model still leaves practical questions about participating institutions and implementation. The historical significance is the alternative architecture it proposed for connecting future domestic digital-money systems.
