Overview
- Mastercard announced its Crypto Credential expansion on November 18, selecting Polygon to process verified-username transfers for self-custody wallets.
- Users can link a human-readable alias to a wallet or request a non-transferable soulbound token on Polygon that certifies ownership by a verified individual.
- Mercuryo serves as the initial issuer, performing identity verification and providing the aliases that connect to user-controlled wallets.
- Mastercard cited Polygon’s speed, low fees, and high throughput as reasons for handling credential-based transfers intended to operate at payment scale.
- No broad consumer rollout date was disclosed, and the move builds on Mastercard’s recent crypto efforts such as debit card partnerships and self-custody integrations.
