Key Takeaway:
- Purpose: multi-year blueprint shaping tokenised wholesale markets, anchored in central bank money.
- Benefits: reduce settlement-asset risk, clarify operating models, steer interoperability.
- Immediate impact: signalling and stakeholder mobilisation via feedback and interest expressions.

The ECB Appia project is a multi‑year design effort to shape tokenised wholesale markets and keep settlement grounded in central bank money, according to the European Central Bank (https://www.ecb.europa.eu/press/pr/date/2026/html/ecb.pr260311~14ddf51a77.en.html). It sets a policy and technology blueprint rather than a production system at this stage.
Appia complements Project Pontes, the near‑term path to settle DLT‑based transactions in central bank money, with operations planned for Q3 2026. The plan also envisages an Appia blueprint or launch paper in 2028.
Expected benefits include reducing settlement‑asset risk by anchoring DLT activity to central bank money, clarifying operating models, and guiding interoperability choices. Immediate impact comes from signalling and stakeholder mobilisation, including a call for feedback and expressions of interest in the announcement.
In practical terms, Appia defines how DLT platforms can achieve delivery‑versus‑payment while using central bank money as the settlement asset. The approach focuses on interfaces and market design rather than replacing existing real‑time gross settlement services.
According to Eurofi, governance, liquidity and standardisation questions are considered manageable after extensive experimentation, even as legal and interoperability work continues (https://www.eurofi.net/wp-content/uploads/2025/12/eurofi-copenhagen-forum-2025.pdf). This context suggests Appia’s work will prioritise resilient connectivity and common standards so tokenised assets can settle safely.
Industry views emphasise interconnection over wholesale replacement of existing market plumbing. “DLT cannot be used for everything, but it is very good at interconnecting things,” said Efthimia Kefalea, Director and Head of Derivatives Clearing Development at Eurex.
Taken together, this framework keeps central bank money at the core while allowing DLT to extend reach across platforms and counterparties. The result, if delivered as outlined, would be tokenised workflows that remain anchored to the safest settlement asset.
