MetaMask, the world's leading self-custodial cryptocurrency wallet, has announced the launch of its new dollar-backed stablecoin, MetaMask USD ($mUSD). This move marks a significant strategic step toward simplifying the user experience and bridging the decentralized Web3 world with traditional finance.

The stablecoin is a collaborative effort, with issuance handled by Bridge, a subsidiary of payments giant Stripe, and powered by the decentralized infrastructure of M0. According to MetaMask, $mUSD will be fully backed 1:1 by high-quality, highly liquid dollar-equivalent assets, ensuring transparency and stability for its users.
$mUSD will initially debut on the Ethereum mainnet and the Linea network, an EVM-compatible Layer-2 solution developed by MetaMask's parent company, Consensys. Its core purpose is to be deeply integrated into the MetaMask wallet’s native features, including fiat currency on-ramps, token swaps, and cross-chain bridging. This functionality is designed to reduce friction and lower barriers for new users entering decentralized space.
The stablecoin's launch is strategically timed to align with recent regulatory developments in the United States. It follows the signing of the GENIUS Act by President Donald Trump in July 2025, a legislative measure that provides a clear federal framework for stablecoin issuance and reserves management. This newfound regulatory clarity offers a legal foundation for platforms like MetaMask.
Looking ahead, MetaMask has ambitious plans to extend the utility of $mUSD beyond its on-chain applications. The company will partner with Mastercard to launch the MetaMask Card, which will allow users to spend $mUSD at millions of merchants worldwide. This move is set to enable a seamless transition from on-chain assets to real-world transactions, enhancing the stablecoin’s value as a foundational asset.
By introducing a wallet-native, self-custodial stablecoin, MetaMask is not just adding another token to the market. It signals a major shift by a key industry player toward building core financial infrastructure that simplifies the user journey and has the potential to drive significant growth in Total Value Locked (TVL) and protocol activity across the DeFi ecosystem.
