MetaMask announces stablecoin, MetaMask USD

• MetaMask USD ($mUSD) is the first native stablecoin launched by a self-custodial wallet, fully integrated into MetaMask’s ecosystem across dapps and DeFi protocols.

• Built with Bridge, a Stripe company, and M0, $mUSD supports on-ramps, swaps, bridging, and will soon be spendable via the MetaMask Card at millions of Mastercard merchants.

• MetaMask USD launches amid growing stablecoin adoption and new regulatory clarity in the U.S., including the GENIUS Act.

• MetaMask USD will be initially launching on Ethereum and Linea and will play a foundational role in the growing Linea DeFi ecosystem and network expansion.

Fort Worth, Texas, USA – August 21st, 2025 - MetaMask, the world’s leading self-custodial crypto wallet developed by Consensys, today announced MetaMask USD ($mUSD), its native stablecoin, marking the first time a self-custodial wallet has launched its own stablecoin. MetaMask USD is issued by Bridge, a Stripe company, and stablecoin issuance and orchestration platform. Onchain, MetaMask USD is powered by M0, a decentralized stablecoin infrastructure and liquidity platform. mUSD will be deeply integrated into MetaMask’s wallet, offering users a seamless, dollar-denominated stablecoin experience for holding, spending, and transacting in web3. Designed for composable cross-chain use via the M0 liquidity network, MetaMask USD sets a new standard for stablecoin utility across MetaMask’s ecosystem, from dapps to DeFi and Payments. It serves as a neutral, highly liquid asset that enables seamless 1:1 fiat-to-crypto onboarding for certain payment methods, unlocking a range of upcoming product integrations and user benefits. 

MetaMask USD will initially launch on Ethereum and Linea, the fully EVM-equivalent L2 bootstrapped by Consensys, where it is positioned to play a foundational role in the Linea DeFi ecosystem. As the network grows, $mUSD will be integrated across core protocols, including lending markets, decentralized exchanges, and custodial platforms, unlocking deep liquidity and utility for users. By enabling native liquidity provisioning and seamless fiat onboarding, $mUSD will help drive sustained TVL growth and protocol activity across Linea.

A new model for stablecoins: wallet-native, self-custodial, and built for utility

Stablecoins are a cornerstone of the crypto economy, underpinning trading, lending, remittances, and DeFi. They provide a crucial bridge between traditional finance and decentralized ecosystems, accounting for nearly $1T in monthly on-chain volume. MetaMask USD introduces a first-of-its-kind model: a self-custodial wallet-native stablecoin accessible to MetaMask’s millions of users across multiple blockchains. It will enhance the experience for users who regularly on-ramp, hold, trade, lend, and spend value directly within the MetaMask wallet. This innovation simplifies the web3 and self-custodial journey while unlocking native utility across DeFi, and real-world payments. 

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, expected by the end of the year: via the MetaMask Card, at millions of merchants worldwide that accept Mastercard

“MetaMask USD is a critical step in bringing the world onchain. By integrating natively into MetaMask’s product offering, it will allow us to cut through some of the most stubborn barriers in web3 and reduce both friction and costs for people onboarding directly into a self-custodial wallet. With MetaMask USD, users can bring their money onchain, put it to work, spend it almost anywhere, and use it like money should be used. We’re not just bringing people onchain. We’re building the reason they’ll never want to leave,” said Gal Eldar, Product Lead at MetaMask.

Built with Bridge and M0 to combine compliance, transparency, and interoperability

Bridge, a Stripe company, is a stablecoin orchestration and issuance platform that offers compliant licensing, monitoring and rigorous reserve management for custom-issued coins. Under the hood, Bridge utilizes the M0 protocol to mint $mUSD which provides a decentralized and extensible stablecoin infrastructure platform purpose-built for interoperability, composability, and transparency, in line with MetaMask's core values. Together, they enable $mUSD to be fully backed 1:1 by high-quality, highly-liquid dollar equivalent assets, with real-time transparency and cross-chain composability.

“We want to empower the builders of great crypto products to truly control the digital dollar stack they utilize in order to deliver the best end user experience,” said Luca Prosperi, Co-founder and CEO of M0. “The current incarnation of stablecoin technology isn’t fit for that purpose. Products such as MetaMask benefit from being able to customize the stablecoin technology, from having choice over their issuance options, and from optimizing for interoperability and liquidity. The M0-Bridge integration offers builders the best stablecoin stack and the most robust issuance capabilities."

“Issuing a custom stablecoin used to take more than a year of complex integrations,” said Zach Abrams, co-founder and CEO of Bridge. “With our issuance technology, we’ve reduced that timeline to a matter of weeks, which means platforms like MetaMask can realize benefits more rapidly and efficiently than ever before.”

MetaMask USD launches at a time of increased regulatory clarity, following the passage of the U.S. GENIUS Act, which introduces the first federal framework for regulating payment stablecoins. 

It is expected to launch later in 2025 initially across Ethereum and Linea. More technical details and user guides will be released in the coming weeks. In the meantime, users can follow MetaMask’s blog and social channels for updates.
