MetaMask, the world's most popular self-custody crypto wallet, is set to launch its dollar-backed stablecoin, MetaMask USD (mUSD), by the end of 2025. Initially debuting on ethereum and Linea (a blockchain developed by ConsenSys, MetaMask’s parent company), mUSD aims to streamline Web3 transactions, reduce fees, and integrate seamlessly with MetaMask’s ecosystem—including its upcoming MetaMask Card. Backed by Stripe’s subsidiary, Bridge, and developed in collaboration with decentralized protocol M^0, mUSD could redefine liquidity in DeFi. Here’s everything you need to know.
Why Is MetaMask Launching Its Own Stablecoin?
MetaMask’s move into stablecoins isn’t just about competition—it’s about control. Luca Prosperi, co-founder and CEO of M^0, put it bluntly: "We want crypto builders to own the digital dollar infrastructure they rely on." By launching mUSD, MetaMask aims to eliminate intermediaries, slash transaction costs, and offer users a frictionless experience. Think of it as merging the simplicity of Venmo with the power of DeFi. And with over 100 million users globally, MetaMask has the scale to make mUSD a default choice.
How Will mUSD Work Within MetaMask’s Ecosystem?
Imagine swapping tokens, bridging across chains, or even spending crypto at your local café—all without leaving your MetaMask wallet. That’s the vision. mUSD will be baked into every MetaMask feature, including:
- Swaps & Bridges: Instant conversions between mUSD and other assets, with cross-chain support.
- MetaMask Card: A Mastercard-powered debit card linked directly to your wallet balance.
- DeFi Integration: Built-in liquidity for protocols like Uniswap and Aave, thanks to M^0’s infrastructure.
Who’s Behind mUSD’s Issuance—and Why Not MetaMask Directly?
Here’s the twist: mUSD isn’t technically issued by MetaMask. Due to the U.S. GENIUS Act (passed in mid-2025), stablecoin issuers can’t offer direct yield on deposits. So MetaMask partnered with, a Stripe subsidiary specializing in stablecoin rails. Bridge handles compliance, while M^0 ensures decentralization. Ajay Mittal, MetaMask’s VP of Product Strategy, hints at future incentive programs—think cashback or staking rewards—but avoids promising yields outright.
What Sets mUSD Apart from Other Stablecoins?
MetaMask’s ace? Distribution. Unlike USDC or DAI, mUSD launches with a built-in user base of 100M+ wallets. Key advantages:
| Feature | mUSD | Competitors |
|---|---|---|
| Fees | Near-zero (subsidized by MetaMask) | 0.1–1% |
| Interoperability | Native to MetaMask’s 20+ supported chains | Often chain-specific |
| Use Cases | Spendable via MetaMask Card | Mostly DeFi-only |
When Can Users Expect mUSD—and What’s Next?
The rollout starts Q4 2025 on Ethereum and Linea, with expansions to Solana and Polygon slated for 2026. MetaMask’s timing is strategic: as U.S. stablecoin regulations solidify, mUSD could dominate a newly legitimized market. And yes, it’ll be the first stablecoin native to a self-custody wallet—no centralized exchange required.

Will mUSD be available on BTCC?
While BTCC (a leading crypto exchange) hasn’t confirmed mUSD listings yet, MetaMask’s partnerships suggest broad exchange support post-launch.

Not directly—but MetaMask may integrate it with DeFi yield programs later, per Ajay Mittal’s comments.
Is mUSD audited?
Yes. Bridge follows Stripe’s compliance standards, with quarterly attestations planned.
