​Non-public joint-stock companies and limited partnerships are required to select an electronic shareholder register operator by the end of June. Only authorised providers of brokerage services, such as brokerage houses, are entitled to operate a register. Asseco Poland has developed PROMAK RA, an IT system for brokers to provide the service. Asseco’s solution is integrated with the Capital Market Blockchain Platform launched by Krajowy Depozyt Papierów Wartościowych (KDPW).
