MetaMask has launched MetaMask USD (mUSD), a US dollar–pegged, wallet-native stablecoin that is now live inside the MetaMask wallet, issued via Stripe-owned Bridge and powered on-chain by the M0 protocol. It is positioned as the first stablecoin created by a self-custodial wallet and is fully integrated across MetaMask’s buy, swap, and DeFi features on Ethereum and Linea. According to MetaMask’s announcement, mUSD is designed to maintain a 1:1 peg to the US dollar, backed by short-term US Treasury bills held in regulated custody, with each token corresponding to an equivalent dollar-backed asset in reserve. The stablecoin is issued by Bridge, a Stripe company focused on stablecoin issuance infrastructure, while M0 provides the decentralized stablecoin infrastructure and liquidity layer that powers mUSD on-chain. This setup allows MetaMask to embed mUSD directly into its wallet interface, enabling users to buy mUSD with fiat, swap into it from other tokens, bridge it across supported networks, and use it as a base asset for DeFi and, eventually, for real-world spending via the MetaMask Card. For users, mUSD functions as MetaMask’s official in-wallet stablecoin, intended to simplify onboarding and reduce friction compared with juggling multiple third-party stablecoins. mUSD is available on both MetaMask Extension and Mobile, with support on Ethereum mainnet and Linea at launch. MetaMask promotes it as a core building block for Linea’s DeFi ecosystem and hints at deeper integrations, including on-ramps and card payments via Mastercard rails, signaling a move by a major self-custodial wallet provider into vertically integrated stablecoin infrastructure.
