In brief
- The experiment targeted promissory notes used in development finance.
- It addressed operational workflows rather than launching a tradeable token.
The development
In April 2025, the BIS Innovation Hub, Swiss National Bank and World Bank reported the results of Project Promissa. The proof of concept explored tokenizing promissory notes: written commitments to pay specified amounts over time. It examined the lifecycle of notes used in multilateral development finance, including issuance, payment and archiving, with an aim of reducing manual processing and reconciliation.
Why it matters
This is a quieter application of tokenization than a new investment product. Its value would come from institutions agreeing on the status of commitments they already manage. The experiment reported technical feasibility, while the partners said more work would be needed to make the platform operational. Readers should distinguish that result from proven savings at production scale. The noteworthy use case is shared administration of development-finance obligations.
