Mastercard is taking a significant step towards simplifying and securing cryptocurrency transactions by expanding its Crypto Credential program to self-custody wallets. This initiative allows users to transact with cryptocurrencies using verified, human-readable aliases, mitigating the risk of errors associated with copying long and complex wallet addresses.
Polygon will be the first blockchain to support this innovative program, while payments firm Mercuryo will handle identity verification and issue the aliases to users. This collaboration aims to make cryptocurrency transactions more accessible and secure for individuals.
Raj Dhamodharan, executive vice president of blockchain and digital assets at Mastercard, stated that Crypto Credential is designed to build trust in digital token transfers by streamlining wallet addresses and adding meaningful verification. Once verified by Mercuryo, users can link a user-friendly alias to their self-custody wallet or request a soulbound token on Polygon, verifying wallet ownership.
Mastercard aims to make self-custody cryptocurrency transfers safer by reducing errors caused by copying lengthy hexadecimal addresses. The system is designed to function more like traditional payment rails, providing a more familiar experience for users.
Marc Boiron, CEO of Polygon Labs, noted, "This partnership marks the moment when self-custody becomes simple."
Mastercard has been accelerating its cryptocurrency strategy throughout 2024 and 2025, launching debit cards with Kraken across Europe and partnering with MetaMask on a self-custody payments card. In June, Mastercard partnered with Chainlink to enable its three billion cardholders to buy crypto directly onchain, marking one of the credit-card giant’s largest steps into Web3.
