Mastercard Partners with Polygon to Replace Complex Wallet Addresses with Simple Usernames
Mastercard is collaborating with Polygon and Mercuryo to replace complex crypto wallet addresses with simple, human-readable usernames for easier transfers.Summary
Mastercard announced a partnership on November 18, 2025, with crypto firm Mercuryo and blockchain infrastructure provider Polygon to enhance its Crypto Credential program by enabling users to send digital assets using simple, human-readable aliases instead of long, complex wallet addresses. This initiative expands to self-custody wallets, requiring users to complete KYC verification with Mercuryo to receive a unique alias linked to their wallet. Polygon provides the underlying blockchain infrastructure, which offers high transaction speed and low fees, making it suitable for financial services. The goal is to solve the major usability barrier in crypto adoption—the risk of sending funds to an incorrect, complex address—by offering an experience similar to popular payment apps while maintaining the security benefits of self-custody. Mastercard views this as a crucial step in bridging traditional finance with decentralized systems, with Polygon CEO Marc Boiron stating this marks the moment when self-custody becomes simple.
