MetaMask to Launch mUSD Stablecoin on Ethereum and Linea

MetaMask has announced plans to launch its stablecoin, MetaMask USD (mUSD), later this year. The token will be issued by Bridge, a Stripe-owned stablecoin platform, and powered by M0’s decentralized infrastructure.

• Launch timing: Scheduled for later this year on Ethereum and Linea.
• Issuer: Stripe-owned Bridge, leveraging M0’s liquidity infrastructure.
• Reserves: Fully backed 1:1 by U.S. cash and short-duration Treasuries.
• Wallet-first integration: Native to MetaMask from launch, unlike most stablecoins.
• Utility: Supports on-ramping, swapping, bridging, transfers, and payments.
• Spending expansion: Planned MetaMask Card support at Mastercard-accepting merchants.

MetaMask, the self-custodial wallet developed by Consensys, has formally unveiled mUSD, its first stablecoin. Designed as a native digital dollar for its ecosystem, mUSD is set to launch later this year on both Ethereum and Consensys’s Linea network.

The stablecoin will be issued by Bridge, the Stripe-owned platform specializing in stablecoin issuance, and minted via M0’s decentralized infrastructure. According to MetaMask, mUSD will be fully collateralized 1:1 by high-quality, liquid dollar equivalents – primarily U.S. cash and short-term Treasuries.

Ajay Mittal, Vice President of Product Strategy at MetaMask, noted that the yield generated from these reserves will allow MetaMask to enhance its services:

“MetaMask benefits from that yield, and in turn, it enables us to improve the user experience across the stack — from potentially lower costs and more seamless integrations.”

Unlike most stablecoins, which are launched independently and later integrated into wallets, mUSD is designed to be native to MetaMask from inception. The wallet’s over 100 million users will be able to:

• On-ramp directly into mUSD
• Hold, swap, bridge, and transfer the token seamlessly
• Spend mUSD through the MetaMask Card at Mastercard-accepting merchants by year-end
  

Mittal emphasized that mUSD is intended to function as the default stablecoin within MetaMask’s ecosystem, supporting DeFi activities from lending to trading. Over time, additional incentives for early adopters may also be introduced.

The launch comes amid strong growth in stablecoin adoption, with nearly $1 trillion in monthly on-chain transaction volume recorded this year. It also follows the passage of the U.S. GENIUS Act, the first federal regulatory framework for payment stablecoins, providing greater clarity for issuers and users alike.

Bridge co-founder and CEO Zach Abrams highlighted the speed of its issuance technology, which reduces deployment timelines from over a year to just weeks. M0 co-founder Luca Prosperi underlined programmability and interoperability as central features of mUSD’s design.

MetaMask has not yet disclosed the initial issuance size or exact launch date. The firm said its priority is ensuring secure and seamless technical operations before release.

Final Thought

The launch of mUSD marks a significant milestone for MetaMask, making it the first self-custodial wallet to introduce its own stablecoin. With deep integrations across Ethereum and Linea, regulatory clarity, and backing from Stripe, mUSD is positioned to play a central role in MetaMask’s strategy to streamline DeFi access and expand utility for its global user base.
