MetaMask has officially launched its stablecoin, mUSD, introducing a wallet-native asset designed to streamline how users interact with crypto. The rollout, which began on September 15, 2025, marks a significant step toward making digital transactions simpler — from converting fiat to crypto and storing value to everyday payments — all within the MetaMask ecosystem.
Developed in partnership with Transak, mUSD is initially accessible to users in the United States and the European Union. The asset is backed at a 1:1 ratio with popular stablecoins USDC and USDT, and its smart contract details are available through MetaMask’s official website.
Beyond serving as a stable store of value, mUSD is intended to act as a link between traditional finance and decentralised applications. It integrates seamlessly with MetaMask’s Swap and Bridge features and can also be used through the MetaMask Card at more than 150 million merchants worldwide. Users benefit from robust liquidity on LineaBuild and low-cost fiat onramps.
Market data shows mUSD with a capitalisation of about $18 million, a circulating supply slightly above that figure, and daily trading volume exceeding $20 million. Its value has remained stable, fluctuating narrowly between $0.99 and $1.01 over the past day.
The launch also brings enhanced functionality to the MetaMask Mobile app, enabling users to top up and manage their MetaMask Card directly. Announced in August 2025, this release is the first time a self-custodial wallet has introduced a deeply integrated stablecoin. On social media, MetaMask credited its partners M0, Stablecoin, and Transak for contributing to the project.
