We're excited to announce Mastercard has chosen Polygon to launch username-based transfers for self-custody wallets, with Mercuryo. Through Mastercard Crypto Credential, users can onboard once, receive a verified username, link their wallet, and get assets instantly. Without ever copying a hex string again. Mercuryo will onboard verified users and issue credentials, while Polygon provides the blockchain rails. Polygon was selected as the default launch chain for one reason: payments. Low-cost infrastructure built for speed, reliability, and scalability. This is how global money moves onchain.
