MetaMask, the leading self-custody wallet, is preparing to evolve from a digital asset manager into a comprehensive financial hub. The company announced plans to launch its first native stablecoin (mUSD) on the Ethereum and Linea networks later in 2025, alongside a payment card powered by Mastercard.

mUSD will be optimized into MetaMask’s wallet interface, which is different from other stablecoins. Existing stablecoins operate as independent tokens on a network. MetaMask users will be able to swap, transfer, and buy mUSD. They will also be able to bridge mUSD between Ethereum and Linea without a third-party platform. This simplifies access to liquidity and improve security within decentralized finance (DeFi).

Bridge will issue the mUSD. It is Stripe’s stablecoin infrastructure that runs on the decentralized protocol M0. The stablecoin provides full transparency and is backed 1:1 by U.S. dollar reserves, cash equivalents, and short-term Treasury bonds. MetaMask has promised to publish real-time reserve data that can be verified by an independent third party. This would put mUSD in line with industry standards set by top stablecoins like USDC.

MetaMask will enter the stablecoin market when there is regulatory clarity. The recent approval of the GENIUS Act in the U.S has set clear federal standards for stablecoin issuers. This gives mUSD a clear legal path to operate in the crypto industry. Analysts believe that this regulatory momentum will further improve MetaMask’s bid for global adoption and increase its institutional credibility.

MetaMask’s Collaboration with Mastercard

In addition, MetaMask has collaborated with Mastercard to launch the MetaMask Card. The card will allow users to use their mUSD at millions of merchants worldwide. This move has the potential to integrate digital currencies into everyday commerce and make the use of digital assets in real life very much possible.

The crypto community has been quick to react. Observers say wallet-native stablecoins could significantly boost liquidity across DeFi ecosystems on Ethereum and Linea. According to CoinDesk, this trend reflects a shift where wallets no longer serve merely as storage tools but become active players in financial infrastructure.

Market analysts are predicting that mUSD has the potential to expand total value lock (TVL) across decentralized exchanges and lending protocols. This will strengthen MetaMask’s position against other centralized stablecoin issuers in the world.
