Mastercard and Polygon Labs partnered to expand the Crypto Credential, using simple, verified usernames to replace complex wallet addresses.
One of the biggest partnerships will streamline the multifaceted nature of cryptocurrency transactions. Mastercard, Polygon Labs, and Mercuryo have stated that the Crypto Credential program will grow considerably. It is a project that introduces authenticated, user-friendly nicknames to high-quality self-custody wallets.
Verified Aliases Replace Complex Wallet Addresses
To be precise, the system is expected to substitute long alphanumeric wallet addresses that are commonly applied to digit assets. Rather, users will be transacting with a simple human-readable alias. The change aims at minimizing errors of transactions and gaining user confidence.

Polygon was chosen as the underlying blockchain network by Mastercard in this implementation. The reason behind the choice of Polygon, which was given by the payment giant, is its speed and the degree of reliability. Moreover, the infrastructure of payments has an infrastructure of high volume, with payments available in the network.

Mercuryo, a crypto payment API company, takes the position of the first alias issuer. The company will be tasked with the responsibility of onboarding and identity verification (KYC) of new users. Mercuryo provides the key to the traditional finance systems.
The unique alias is connected with the self-custody wallet of the user after verification. This authentication creates an extra protective layer of security and trust in the transfer process. Thus, users will be able to share and verify the details of the recipients.
Strategic Move Enhances Compliance and Mass Adoption
The mechanism operates through the implementation of a common authentication of blockchain addresses. As a result, the confirmed alias belongs to a confirmed person. This does away with confusion experienced in complex hexadecimal strings.
Mastercard, the Executive Vice President of Blockchain, Raj Dhamodharan, celebrated the partnership. He emphasized that the simplification of the addresses and verification develops trust in the transfers. In addition, the alliance increases access to digital assets across the globe.
Moreover, the larger project promotes vital compliance with regulations. The Crypto Credential program will help in compliance with the global Travel Rule. The standard is aimed at safeguarding the traceability of cross-border transfers.
Furthermore, it is possible to apply a soulbound token on the Polygon network. This token is an on-chain indicator of the verifiability of the transaction of the wallet. This aspect will guarantee an interoperable and simplified experience.
Analysts have been following the success of the Polygon token, POL (which used to be called MATIC). According to CoinMarketCap data, it is trading around 0.144254, but in 2025, it is forecasted that it will hit a gross of 0.70.
Finally, this program shifts cryptocurrency transactions to conventional flows of payments. It is about convenience, ease, and consumer security. This collaboration is a major milestone towards the mass adoption of self-custody.
Lastly, Mastercard Crypto Credential intends to use it outside its peer-to-peer payments. As an illustration, the system will be broadened to cover NFTs and event ticketing solutions use cases.
