MetaMask mUSD Stablecoin: Rapid Adoption, Features, and Future Expansion
MetaMask's mUSD Stablecoin: A Game-Changer in the Crypto Space
On September 15, 2025, MetaMask unveiled its native stablecoin, mUSD, marking a pivotal moment in the cryptocurrency industry. Within just one week, mUSD's circulating supply skyrocketed to $65 million, a staggering 300%+ growth from its initial supply of $15 million. This rapid adoption is fueled by MetaMask's extensive ecosystem, which boasts over 30 million monthly active users.
With seamless integration into MetaMask's wallet, mUSD is positioned as a strong competitor to established stablecoins like USDT and USDC, offering users a transparent, compliant, and user-friendly alternative.
Why mUSD Stands Out in the Stablecoin Market
Seamless Wallet Integration
MetaMask's wallet ecosystem provides unparalleled accessibility for mUSD users. With over 30 million monthly active users, the stablecoin benefits from a built-in audience that can:
Send funds to friends and family.
Swap tokens effortlessly within the wallet.
Spend mUSD at merchants worldwide.
Additionally, the MetaMask Card integration allows mUSD to be spent at over 150 million Mastercard-accepting merchants globally. Full functionality is expected by the end of 2025, bridging the gap between digital assets and real-world spending.
Deployment Across Linea and Ethereum Networks
MetaMask has strategically deployed mUSD across two networks:
Linea (88.2% of supply): MetaMask's Ethereum-compatible Layer 2 network offers lower transaction costs and faster speeds, addressing common blockchain pain points.

This dual deployment underscores MetaMask's commitment to enhancing user experience while maintaining robust network functionality.
Backing and Collateralization: A Trustworthy Stablecoin
mUSD is issued through Stripe's Bridge platform and minted using M0's decentralized infrastructure. Each mUSD token is backed 1:1 by high-quality, liquid dollar-equivalent assets, such as U.S. Treasury bills. This ensures:
