Mastercard Partners With Polygon, Mercuryo to Simplify Self-Custody Transfers

Mastercard, Polygon Labs, and Mercuryo have announced an expansion of the Mastercard Crypto Credential to self-custody wallets, introducing verified, username-style aliases designed to replace traditional long-form wallet addresses.

Mastercard said it tapped Polygon first due to the network’s speed, reliability, and payments-ready infrastructure for supporting the rollout. Meanwhile, Mercuryo will act as the initial issuer responsible for onboarding verified users and creating Mastercard Crypto Credential aliases.
