Mastercard Chooses Polygon for Username-Based Wallet Transfers Expansion

Mastercard Partners with Polygon and Mercuryo for Crypto Transfers

  • Mastercard has selected Polygon Labs to enable verified username transfers across self-custody wallets.
  • The collaboration with payment API firm Mercuryo will involve verifying users and issuing aliases linked to their on-chain identities.
  • Polygon was chosen due to its transaction speed, reliability, and payments-oriented infrastructure.

Mastercard's Crypto Credential Framework

  • The framework introduces standardized verification for blockchain addresses using human-readable aliases.
  • Mercuryo will manage identity verification and issuance of aliases, similar to mainstream payment apps.
  • Users can obtain a Polygon-based token indicating wallet support for verified transfers.
  • This initiative follows Mastercard's previous collaboration with Chainlink.

Technology and Collaborations

  • Polygon’s Proof-of-Stake chain offers fast settlement, low transaction costs, and high throughput.
  • Recent upgrades have improved finality and expanded transaction capacity.
  • Mastercard, Ripple, Gemini, and WebBank are exploring using Ripple’s RLUSD stablecoin for fiat credit card settlements.
