MetaMask USD, ticker mUSD, is a USD-pegged stablecoin connected to the MetaMask ecosystem. It represents a digital dollar-style asset that can be used inside crypto wallets, decentralized apps, and exchange flows without moving back into traditional money. Like other stablecoins, mUSD exists to make crypto activity easier to price, send, and settle in familiar U.S. dollar terms.
History, founders, project achievements of MetaMask USD
MetaMask USD was introduced by MetaMask, the Web3 wallet developed by Consensys. The token is issued by Bridge, a Stripe company, using M0 infrastructure, and is backed 1:1 by high-quality, highly liquid dollar-equivalent assets. MetaMask itself was created by Aaron Davis and Dan Finlay and became one of the most recognizable gateways to Ethereum and decentralized applications. mUSD represents a later step in that story: a stablecoin built around the idea that a wallet can offer a dollar-denominated asset directly within the crypto experience.
MetaMask USD launched in 2025 as a wallet-native stablecoin for the MetaMask ecosystem. Its development reflects a broader shift in crypto: stablecoins are no longer used only for trading pairs on exchanges, but also for payments, DeFi activity, savings-like balances, and everyday transfers between wallets.
mUSD is pegged to the U.S. dollar because USD remains the most common reference point for pricing crypto assets, measuring portfolio value, and settling transactions. For many readers, the main point is simple: mUSD is meant to behave like a digital representation of dollar value while staying usable on supported blockchain networks.
The peg and depeg concept is important to understand. Although mUSD is designed to maintain a value close to 1 USD, its market price can fluctuate due to market volatility, changes in supply and demand, liquidity, or temporary deviations from its peg.
What mUSD represents and how it is used
mUSD crypto is designed for people who want dollar-denominated value in a Web3 wallet environment. Instead of holding a volatile asset only to make a payment or interact with an app, mUSD can provide a more predictable unit of account for supported crypto activity.
Common use cases for the mUSD coin include moving value between wallets, keeping funds in a dollar-referenced asset, interacting with decentralized applications, and exchanging into or out of other cryptocurrencies. It can also be useful when you want to compare crypto prices without constantly recalculating them against a volatile asset.
Its main characteristics are straightforward: mUSD is dollar-pegged, crypto-native, wallet-oriented, and intended for use across supported networks. For readers already familiar with MetaMask, the asset fits into a broader Web3 experience rather than standing alone as a separate financial app.
MetaMask USD market cap refers to the total market value of mUSD in circulation. It is generally calculated by multiplying the circulating supply by the current MetaMask USD price.
This figure can change as supply changes or as the market price moves around its intended dollar value. For live mUSD price, market cap, and other market data, check the price chart and asset information displayed at the top of this SwapSpace page.
A MetaMask USD wallet is any compatible crypto wallet that supports the network version of mUSD you hold. Wallet support depends on the relevant network, so always make sure the wallet and network match before storing or exchanging the asset.
- MetaMask: The most direct wallet choice for mUSD, especially because the asset is connected to the MetaMask ecosystem.
- Rabby Wallet: A Web3 wallet often used for EVM-compatible networks and DeFi activity.
- Trust Wallet: A multi-asset wallet that supports many popular crypto networks and tokens.
- Ledger: A hardware wallet option for storing supported assets with cold-wallet security, typically through compatible wallet interfaces.
- Coinbase Wallet: A self-custody wallet that supports a range of Web3 assets and networks.

MetaMask USD launched on Ethereum and Linea and has since also become available on Monad. Ethereum gives mUSD access to a large DeFi and wallet ecosystem, while Linea, developed by Consensys, connects the asset to a network closely tied to the broader MetaMask environment.
The practical point is network compatibility. The network you choose affects where you can hold, send, and exchange mUSD, as well as which apps may recognize it. If you want more background on how networks differ, SwapSpace’s overview of blockchain networks offers a helpful introduction.
