Introducing MetaMask USD: Your Dollar, Your Wallet

Meet MetaMask USD, aka mUSD, our new stablecoin that makes getting started with crypto and trading tokens easier, faster, and more cost-effective than ever before. mUSD is the first stablecoin built directly into a self-custodial wallet, combining the reliability of the US Dollar with MetaMask’s trusted security. From onboarding to earning, holding to spending, mUSD allows you to make the most of your assets, all within your MetaMask wallet.

Launched in September 2025, and supported on Ethereum Mainnet and Linea, every mUSD in circulation is pegged 1:1 with short-term US Treasury bills, ensuring that your digital assets maintain their value and are always redeemable. Created in partnership with Bridge and powered by the M0 protocol, this backing gives you stability, whether you’re moving funds across chains or parking value. 

As a wallet-native stablecoin, mUSD integrates seamlessly into MetaMask. It allows you to easily buy crypto with fiat, swap or trade directly within your wallet, participate in DeFi protocols, and even spend crypto IRL via MetaMask Card.

mUSD also unlocks lending, trading, and yield options while minimizing exposure to token price swings. For everyday users, it bridges the gap between traditional finance and DeFi, making transfers, remittances, and payments easier and more stable.

Three easy ways to get mUSD

Getting started with mUSD is simple:

1. Deposit with Native Onramps
