Traditional Finance Meets Self-Custody Innovation
Mastercard Crypto Credential extends its reach into the self-custody wallet sector via a new partnership with Polygon Labs.

This expansion of Mastercard Crypto Credential represents a major step toward making self-custody intuitive for mainstream users, while also enabling them to maintain the independence and protection of their assets that come from a decentralized finance (DeFi) experience.

Simplified User Experience Through Verified Identities
The enhanced Mastercard Crypto Credential system replaces the complex hexadecimal wallet addresses (currently the standard for blockchain wallets) with human-friendly and comprehensible aliases tied to verified user identities.
Through partnership with verification provider Mercuryo, users undergo a one-time Know Your Customer (KYC) onboarding process and receive a portable credential that works across the Crypto Credential network.
The overall vision for this program is to help maintain basic privacy for the user while ensuring the necessary level of trust and authentication to enable secure transactions, thereby bridging traditional financial verification standards and blockchain’s permissionless nature.
