Mastercard Extends Crypto Credential to Self-Custody Wallets on Polygon

Mastercard cites low fees, fast finality, plus payments-scale capacity.

Overview

  • The expansion introduces verified, human‑readable aliases that users link to self‑custody wallets after completing KYC with Mercuryo.
  • Users can optionally mint a non‑transferable credential on Polygon that attests to a verified wallet and enables apps to route credential‑based transfers.
  • The initial release is receive‑only via aliases, with outbound sending planned next, and availability will roll out gradually to select users.
  • Polygon was chosen for performance and reliability, including low fees, high throughput, and recent Rio and Heimdall v2 upgrades that improve finality and remove reorg risk.
  • Market commentary reports no immediate boost to Polygon’s POL token following the announcement.
