Polygon (POL) just announced a new deal with MasterCard, one of the two globe’s largest payment card providers. Via the MasterCard Crypto Credential, an additional verification layer is going to be placed on self-custodial environments.
What Polygon’s MasterCard Credentials Offer To Users?
This enables recognizable user names instead of cryptographic wallet addresses, mapped to verified individuals. Alias issuance and personal verification will be handled by Mercuryio, which is tasked with assigning the newly-forged nicknames to wallet addresses.
Polygon’s technology is employed to issue the following soul-bound token to verify the publicly verified owner of the wallet & enable credential-based transaction processing on Polygon’s L2 chain. According to a MasterCard’s representative, Polygon is the top choice due to the chain’s payment-ready infrastructure, network speed & reliability.

MasterCard’s Raj Dhamodharan, the Executive Vice President of Blockchain & Digital Assets, explained: “Bringing Mercuryo and Polygon’s capabilities together with our infrastructure makes digital assets more accessible and reinforces Mastercard’s commitment to delivering secure, intuitive, and scalable blockchain experiences for consumers worldwide.”
However, the positive MasterCard integration news barely touched Polygon’s (POL) market price, as the altcoin dipped below $0.15. Along with the broader bearish tide still rattling the markets, POL’s price tumbled in double-digit percentages since last week, now 24% down in monthly terms.

MasterCard partnered with Polygon and Mercuryo to let anyone turn their Polygon wallet into a simple username like @john.pol. Instead of copying 42-character addresses, you just send crypto to a human-readable name.
You verify your identity once through Mercuryo, then get a custom alias tied to your wallet plus an optional soulbound token (SBT)—a non-transferable NFT that lives forever on your address and proves you’re verified on-chain.
Unlike normal NFTs you can sell, soul-bound tokens can’t leave your wallet, so the “verified” badge stays with you permanently and can’t be faked or traded away.
Polygon Layer-2 is lightning-fast and costs pennies per transaction, making it the perfect chain for everyday payments MasterCard wants to feel like cash apps.
It’s live right now on Polygon self-custody wallets through Mercuryo-powered apps; more chains and bigger rollout coming in 2026.
