DRep Delegation#

DRep (Delegation Representative) delegation enables users to participate in Cardano's governance system by assigning their voting power to chosen representatives. By integrating DRep delegation into your application, you empower users to influence the blockchain's future without requiring them to actively participate in every governance decision.
