## Lesson topic

**Project Dunbar shows that cross-border tokenized-asset settlement needs access, jurisdiction and governance rules, not just a shared ledger.**

## Extracted official-source facts

- BIS describes Project Dunbar as a project led by the BIS Innovation Hub in partnership with the Reserve Bank of Australia, Central Bank of Malaysia, Monetary Authority of Singapore and South African Reserve Bank.
- The BIS page says Dunbar explored how a common platform for multiple central bank digital currencies could enable cheaper, faster and safer cross-border payments.
- BIS says the project identified challenges of implementing a multi-CBDC platform shared across central banks and proposed practical design approaches.
- BIS says the design approaches were validated through technical prototypes on Corda and Partior, proving the concept of multi-CBDCs was technically viable.
- The PDF says one key cross-border payment challenge is fragmentation, and Project Dunbar explored a common platform that would allow participating central banks and financial institutions to transact directly with each other in CBDCs.
- The PDF highlights three critical challenges for a shared multi-CBDC platform: access, jurisdictional boundaries and governance.
- The PDF describes access design as enabling non-resident banks' access to CBDCs, including hybrid and direct access models depending on local regulatory frameworks.
- The PDF describes jurisdictional-boundary design as separating settlement processes from non-settlement processes so local regulatory policies can still apply.
- The PDF frames shared-platform governance as a balance between universality/common rules and the autonomy of participating central banks and jurisdictions.

## No-hype summary

Project Dunbar is useful for RWA learners because it explains why cross-border settlement is not solved by putting tokens on one ledger. If a tokenized bond, fund unit, invoice or deposit token is meant to move across borders, the payment leg still has to answer institutional questions: who can access the settlement asset, which jurisdiction's rules apply, which processes stay local, what rules are common to all participants, and which central bank or operator can change or pause the system.

The lesson is not that every RWA platform needs CBDC, or that a multi-CBDC platform is imminent. The lesson is that serious cross-border tokenization requires explicit access, legal-boundary and governance design before the technology can deliver cheaper or safer settlement.

## Practical watch question

When a tokenized-asset platform advertises cross-border settlement, ask: **who is allowed onto the settlement rail, what law governs the transaction, which parts happen off-platform, and who has authority over shared rules or emergency actions?**
