Mastercard indicated that it selected Polygon as the inaugural blockchain for this initiative, highlighting the network’s speed, dependability, and appropriateness for payment infrastructure. Mercuryo will act as the primary issuer tasked with verifying users and facilitating the creation of new Crypto Credential aliases.
Identity Verification Meets Human-Readable Wallets
Mercuryo stated it will perform identity verifications and issue the aliases, which users can link to their wallets throughout the network. Additionally, users may request a Crypto Credential soulbound token on Polygon, demonstrating on-chain that the linked wallet is associated with a verified user.
The transition from lengthy hexadecimal wallet strings aims to minimize errors and enhance trust in digital transactions. A single verified alias recognized across the Crypto Credential network brings blockchain usage closer to conventional payment processes, the firm noted.
Polygon Positioned as Payments-Grade Infrastructure
Mastercard’s choice to utilize Polygon underscores the network’s focus on scalability and reliable settlement. The Polygon Proof-of-Stake chain provides low transaction fees, high throughput, and swift confirmation times suitable for real-world payment activities.

Recent enhancements—including the Rio and Heimdall v2 updates—have bolstered finality guarantees, reduced reorganization risks, and set the stage for increased throughput. Polygon already manages a significant portion of U.S. stablecoin transfers and supports a wide array of neobanks and fintechs integrating digital asset solutions.
Polygon Labs CEO Marc Boiron remarked that the partnership demonstrates how blockchain networks can fulfill the requirements of mainstream financial services, adding that success will be achieved as blockchain becomes “invisible” to end users.
Toward Mainstream Self-Custody and Onchain Payments
Mercuryo’s function in verifying users and issuing credentials aims to make self-custody wallets more accessible, providing a clearer, user-friendly process for managing digital assets.
The companies assert that advancements in verification and user experience are driving self-custody beyond niche applications toward wider consumer acceptance.
Mastercard executives positioned the initiative as part of the firm’s ongoing commitment to fostering trust in blockchain-based transactions and delivering intuitive digital asset experiences at scale.
The expansion of Crypto Credential reflects a broader industry trend where payments, identity, and blockchain infrastructure increasingly converge. As financial institutions enhance on-chain capabilities, frameworks like Crypto Credential—and networks like Polygon—are instrumental in shaping the future of global payments.
