MetaMask Launching mUSD Stablecoin With Stripe and Blackstone Backing

MetaMask is preparing to launch its own USD-pegged stablecoin, mUSD, later this month, in partnership with Stripe’s Bridge, M^0, and Blackstone.

What Happened?

MetaMask, one of the most popular Ethereum-based wallets, is entering the stablecoin market with a new USD-pegged token called mUSD (also referenced as mmUSD). The stablecoin is expected to go live by the end of August, following an announcement anticipated this week.

The launch involves several major financial players including Stripe’s crypto payments arm Bridge, decentralized stablecoin issuance protocol M^0, and global asset manager Blackstone, who will provide custody and treasury management.

MetaMask Enters the Stablecoin Arena

MetaMask is aiming to transform from a crypto wallet into a more expansive financial service platform. Its new stablecoin, mUSD, will be backed by short-term US Treasuries, making it similar to USDC and USDT in structure and reserve assets. This model not only ensures price stability but also allows MetaMask to earn yield from the interest on government bonds, creating a fresh revenue stream.

Key highlights of the mUSD launch:

• Backed 1:1 by the US dollar with reserves held in liquid, short-term securities.
• Bridge, a payment rails firm owned by Stripe, will handle payment integration.
• M^0 will power the technical architecture of mUSD issuance and operations.
• Blackstone will oversee custody and treasury services, providing institutional-grade oversight.

This setup is designed to meet growing regulatory demands, especially following the passage of the GENIUS Act in the US, which gave clearer legal guidelines for stablecoin issuers.

Strategic Timing Amid Market Growth

The timing of MetaMask’s stablecoin release is no accident. The stablecoin market is currently valued at $280 billion, with banks like Standard Chartered forecasting that number could climb to $750 billion by 2026.

Other traditional financial giants such as JPMorgan Chase, Bank of America, and Robinhood are also eyeing the stablecoin sector, either by launching their own tokens or partnering with blockchain firms.

MetaMask’s parent company, Consensys, has so far declined to officially confirm details of the launch. However, sources suggest the stablecoin project was inadvertently revealed last week through a short-lived governance proposal on the Aave platform.

Expanding the MetaMask Ecosystem

With over 30 million monthly active users, MetaMask already commands significant influence in the crypto wallet space. By integrating mUSD as a primary trading and DeFi asset within its app, the company is creating a vertically integrated ecosystem.

Recent updates include:

• Yield generation features via Aave integration directly in MetaMask Mobile.
• Fiat off-ramp expansion to 10 blockchain networks, including Arbitrum and Base.
• Plans to make mUSD the default asset across MetaMask services.

These moves suggest MetaMask is preparing to compete directly with stablecoin giants like USDT and USDC, not just as a wallet, but as a self-sustaining digital finance platform.

CoinLaw’s Takeaway

I think this is a big, bold move from MetaMask. They’re not just dipping into the stablecoin waters; they’re diving in headfirst with some heavy hitters like Stripe and Blackstone. What excites me is how they’re turning a wallet app into a yield-generating, DeFi-enabled powerhouse. And with the stablecoin market poised to nearly triple, this launch is perfectly timed. It’s not just another token. It’s MetaMask staking its claim in the future of digital finance.
