Mastercard Picks Polygon for Self-Custody Identity Upgrade

Mastercard has expanded its Mastercard Crypto Credential program to self-custody wallets, and selected Polygon as the first blockchain network to support the rollout. Together with Polygon Labs and Mercuryo, Mastercard is introducing verified, username-style aliases that replace long wallet addresses, bringing a familiar, Web2-like UX to Web3 value transfers.

The upgrade enables users to link a self-custody wallet to a verified alias, receive assets using that username, and optionally mint a soulbound credential on Polygon. Mercuryo handles KYC onboarding and credential issuance, while Polygon provides the speed, reliability, and low-cost infrastructure required for identity and payments at global scale.

Polygon’s selection is driven by its enterprise-friendly architecture: sub-cent fees, instant settlement, high throughput, and no reorg risk following the recent Rio and Heimdall v2 upgrades. With stablecoin volume already in the billions monthly and strong penetration among neobanks and payment providers, Polygon is well-positioned to power next-generation digital identity and payment rails. The collaboration marks a major step toward mainstream-ready self-custody, intuitive, secure, and trusted.

Technical Outlook, Mastercard (MA)

Mastercard’s stock is pulling back toward a multi-year ascending trendline, aligning with a major liquidity zone below the $527 low. The chart shows a potential sling low forming, with price rebounding from trendline support historically before rallying toward prior highs.

If bulls hold support, the next upside target is the $600–$602 resistance level. A breakout above this zone could open a path toward new all-time highs, aligning with improving sentiment around digital payments and Mastercard’s increasing involvement in blockchain infrastructure.

Momentum indicators signal near-term exhaustion, but the macro trend remains intact. A clean reaction from support could trigger a medium-term recovery.
