MetaMask mUSD stablecoin is gaining strong momentum after recording a rapid supply increase within a week of launch.
Early Monday morning, data showed its supply had reached $65 million, compared to $15 million just a week earlier.
This fast growth highlights strong market confidence in MetaMask’s decision to enter the stablecoin market. The mUSD stablecoin is fully backed 1:1 by highly liquid dollar-equivalent assets. MetaMask confirmed the launch last Monday, noting that the stablecoin leverages decentralized minting via M0 and is issued through Bridge, Stripe’s stablecoin platform.
Market confidence is visible in supply growth
Stablecoins remain essential for crypto activity, enabling dollar-backed transfers across decentralized applications. From my standpoint, the rapid expansion of the MetaMask mUSD stablecoin reflects how established wallets can drive stablecoin adoption. Dune Analytics data shows 88.2% of mUSD supply is deployed on Linea, while Ethereum holds the remaining 11.8%. This distribution suggests Linea users are the first strong adopters of the new asset.
Data from The Block further supports the context. The total circulating supply of dollar-pegged stablecoins reached $279.8 billion as of Sunday. USDT continues to lead with $172.3 billion in supply. The rising role of MetaMask mUSD stablecoin adds another choice in the competitive stablecoin market.

Growing demand for crypto stablecoins
Stablecoins are now central in global crypto transactions. They offer predictable value and instant liquidity. MetaMask, a leading crypto wallet, has taken the next step by launching mUSD to extend its user ecosystem. MetaMask’s influence as a wallet provider allows direct integration of the stablecoin into user flows, from trading to payments.
Regulatory clarity also plays a role. The U.S. GENUS Act, passed in July, has made stablecoins a policy priority. Last week, the Treasury Department announced it was seeking public feedback on how to implement the law. This timing supports the growth of new offerings like the MetaMask mUSD stablecoin, as both regulators and industry players align toward adoption.
New players and competition
Other projects are also pushing forward. Layer 1 blockchain Kaia and LINE NEXT announced their plan to launch a stablecoin superapp later this year on LINE’s Dapp Portal. This competition shows that crypto stablecoins remain an active race, with new entrants looking for market share.
MetaMask has a clear advantage by embedding mUSD directly within its widely used wallet. With over 30 million users globally, MetaMask provides immediate access to a new stablecoin without requiring additional onboarding steps. This ease of use may accelerate the mUSD adoption rate faster than other projects.
Key takeaway on MetaMask mUSD stablecoin
The launch week numbers indicate strong demand and utility for the MetaMask mUSD stablecoin. Backed by dollar-equivalent assets, issued through a secure infrastructure, and rapidly integrated on Linea and Ethereum, mUSD has shown immediate traction.
If you ask me, this first-week performance sets the foundation for wider adoption. Stablecoins are not only about trading but also about payments and future financial products. MetaMask’s move may be one of the most practical steps toward expanding stablecoin use.
