The European Central Bank has invited financial market stakeholders and public sector bodies to express interest in participating in the Appia contact group, which will support the Eurosystem’s Pontes and Appia projects. The group will provide input on the Eurosystem’s work on tokenisation and distributed ledger technology, including business and technical issues in the development of a tokenised wholesale financial market. Its remit covers the operation and evolution of Pontes, including user requirements, risk management, and change and release management, as well as the Appia blueprint through exchanges on advances in distributed ledger technology, standardisation, and technical and business topics in the Appia roadmap. The contact group will include private and public stakeholders and national central banks. Pontes and Appia were launched in 2025. Pontes is intended to link market distributed ledger technology platforms with TARGET Services so tokenised assets can be settled in central bank money, while Appia sets out the longer-term vision for a European tokenised financial ecosystem. Financial market stakeholders interested in joining the group must complete the online application form by 19 June 2026.
