MetaMask has launched its first native stablecoin, MetaMask USD ($mUSD), on Ethereum and Linea, in collaboration with Bridge and M0, announced on August 21, 2025.
The launch signals a shift in the stablecoin market dynamics, leveraging regulatory clarity and enhancing wallet functionalities, potentially increasing user adoption in decentralized finance ecosystems.
MetaMask has announced the launch of its first native stablecoin, MetaMask USD ($mUSD), in partnership with Bridge (a Stripe company) and M0 for decentralized infrastructure. Initial rollouts are designated for Ethereum and Linea networks.
Key players in the initiative include Consensys, founded by Joseph Lubin, and Bridge for licensing and compliance. The launch supports MetaMask’s broad ecosystem, impacting over 30 million active users.
“MetaMask USD ($mUSD) is the first native stablecoin launched by a self-custodial wallet, fully integrated into MetaMask’s ecosystem across dapps and DeFi protocols.” — Joseph Lubin, Co-founder, Consensys
The introduction of mUSD is set to impact the stablecoin market significantly. Industry experts cite increased liquidity integration for DeFi as a major outcome. Concerns revolve around its pressure on competitors like Circle and Tether.
Financially, mUSD aims to reduce on-ramp costs and friction, potentially increasing Total Value Locked (TVL) in the associated DeFi ecosystems. Regulatory implications are guided by the US GENIUS Act.
The strategic move by MetaMask signifies a pivotal point in blockchain and decentralized finance. The anticipated effects on Ethereum’s and Linea’s infrastructures will be closely monitored, providing a case study in how regulatory frameworks support innovation.
The rollout is considered pioneering, as no self-custodial wallet previously launched an integrated, natively issued stablecoin. Observers highlight the importance of 1:1 dollar backing and transparent liquidity handling in ensuring market confidence.
