KDPW CSDonDLT (blockchain layer of Poland's central securities depository)New

A blockchain layer that Poland's central securities depository KDPW is building alongside its existing depository and settlement system. Securities can move from the traditional layer to the DLT layer and back; the first scope is safekeeping, free transfers and atomic settlement of OTC trades. StaBillon, a KNF-licensed e-money institution, is to provide digital Polish zloty for the cash leg so trades can settle delivery versus payment. Testing with KDPW participants began in May 2026, either through KDPW's applications or by running their own node on KDPW's Blockchain Platform for the Capital Market.
