What happens when one of the world's most popular self-custodial wallets decides to launch its own stablecoin? That's exactly what we're seeing with MetaMask's new mUSD, which officially went live on Monday September 15, 2025. As Cryptopolitan reported, MetaMask aims to enter the $290 billion growing stablecoin market in partnership with Stripe.
Issued by Bridge, a Stripe-owned stablecoin platform, and minted via M0's decentralized infrastructure, mUSD promises real-time transparency, cross-chain liquidity, and full 1:1 backing with highly liquid dollar-equivalent assets. With over 30 million monthly active users worldwide, MetaMask's leap into stablecoins could reshape how people use digital dollars.

Tether (USDT) and Circle's USDC dominate the market, but fresh competition is heating up. In just the past two months, Tether unveiled plans for USAT, Hyperliquid rolled out its own stablecoin USDH, and U.S. banks began exploring tokenized dollars thanks to clearer regulations. Against this backdrop, MetaMask's move positions mUSD as not just another token but the default unit of account across its own ecosystem.
What Are the Key Features of mUSD, MetaMask's Stablecoin?

How is mUSD different from the dozens of other dollar-pegged tokens out there? For starters, this is the first stablecoin ever launched by a self-custodial wallet, giving MetaMask users a native digital dollar fully integrated into the app. That means you can soon on-ramp, hold, swap, transfer, and bridge mUSD without leaving MetaMask. And by the end of 2025, you may even be able to spend mUSD directly with the MetaMask Card at millions of Mastercard-accepting merchants worldwide, a first step toward mainstream payments.
MetaMask users now have access to mUSD, a dollar-denominated stablecoin designed to integrate seamlessly across dapps and DeFi protocols within the MetaMask ecosystem. With mUSD, users can on-ramp, swap, transfer, and bridge instantly, while also gaining the ability to make everyday purchases through the MetaMask Card, accepted at Mastercard-supported merchants worldwide. The MUSD stablecoin is issued by Bridge, a Stripe-owned company, which utilizes the M0 protocol for minting and burning, making Bridge the first U.S.-regulated issuer on the M0 network.

Beyond simple transactions, mUSD is built for transparency and utility, as users can track critical metrics such as circulating supply, collateralization ratios, and other M0-powered stablecoins directly within the M0 ecosystem dashboard. More than just a digital dollar, mUSD represents a step toward customizable, application-specific stablecoins built on M0's universal platform, ensuring flexibility and scalability for developers and users alike.
According to the MetaMask website, 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
mUSD Adoption Could Benefit From MetaMask's 100M+ Users
If even a fraction of MetaMask's massive 100+ million user base embraces mUSD, it could quickly scale into the billions. The key test will be whether users prefer a wallet-native stablecoin over existing giants like USDT and USDC.
MetaMask USD has launched at a time when stablecoin adoption is accelerating and new U.S. regulatory clarity, including the recently introduced GENIUS Act, is shaping the market. The stablecoin debuts on Ethereum and Linea, where it is expected to serve as a foundational asset, supporting the growth of the Linea DeFi ecosystem and fueling the network's broader expansion.

Other Ways to Add Funds to Your MetaMask Wallet

These options offer flexibility, but fees, slippage, and network conditions may vary.
Conclusion
Could mUSD mark the start of a new phase where wallets issue their own stablecoins? With MetaMask blazing the trail, other crypto wallets might follow suit, creating direct competition with exchanges and banks. The timing is significant, stablecoins are increasingly seen as the backbone of digital payments, and control over them could determine who leads in the next wave of crypto adoption.
