What is MetaMask USD?

MetaMask has introduced MetaMask USD (mUSD), the first stablecoin native to a self-custodial wallet, fully integrated into the MetaMask ecosystem. Issued via Bridge—a Stripe-owned stablecoin issuance platform—and powered by the decentralized liquidity infrastructure M0, mUSD is backed 1:1 by U.S. cash and short-duration Treasuries, with real-time transparency and monthly attestations of reserves. The launch is timely, aligning with the regulatory clarity introduced by the U.S. GENIUS Act, which provides a federal framework for payment stablecoins. Aimed at reducing friction in Web3 onboarding, mUSD is poised to deepen liquidity and streamline DeFi engagement.

MetaMask USD will be usable in two key ways:

• In wallet at launch: for seamless onramps, swaps, transfers, and bridging across chains

• In real life: via the MetaMask Card, at millions of merchants worldwide that accept Mastercard
