MetaMask USD (MUSD)

MetaMask USD (mUSD) is a US dollar-pegged stablecoin associated with the MetaMask ecosystem. It is designed to maintain a one-to-one value relationship with the US dollar and to serve as a practical settlement and payment asset for users who interact with decentralised applications, wallets, exchanges, and crypto payment tools.

MetaMask is one of the most widely used self-custody wallets in the Ethereum and EVM-compatible blockchain ecosystem. Its users rely on the wallet to store assets, connect to decentralised finance protocols, trade tokens, manage NFTs, bridge between networks, and interact with Web3 applications. mUSD is positioned as a stable medium of exchange within that environment, reducing the need for users to move between external stablecoins, bank accounts, and separate payment services.

The stablecoin is intended to support low-friction transfers and near-instant settlement across supported blockchain networks. It can also be used in MetaMask-linked products, including fiat on- and off-ramp services and payment solutions such as the MetaMask Card where available. This gives mUSD a role not only as a trading or DeFi asset, but also as part of a broader effort to connect crypto balances with everyday spending.

Like other fiat-referenced stablecoins, mUSD depends on reserve management, redemption processes, issuer controls, and regulatory compliance to preserve confidence in its peg. Users should evaluate where the token is issued, which networks support it, what redemption rights apply, and how it fits within the wider stablecoin market before treating it as a cash-equivalent asset.
