Reusable Payment Addresses (#RPA) is a privacy feature introduced by the BCH wallet #ElectronCash.
When using RPA, Electron Cash generates a "Pay-Code" for the user, which serves as a unique identifier associated with multiple payment addresses. This "#PayCode" creates a new receiving public key address for each payment, ensuring it is not linked to any of the user's previous addresses.
When receiving transactions, the recipient only shares this "Pay-Code" instead of the actual address.
This method significantly limits the amount of information accessible by external parties, making it more difficult for adversaries to decrypt transactions, thus enhancing #privacy protection.
