MetaMask, the self-custodial crypto wallet developed by Consensys, is set to launch its own native stablecoin, MetaMask USD (mUSD).

This makes it the first self-custodial wallet to issue a stablecoin, strengthening its role as a central gateway to decentralized finance (DeFi).

Speculation about mUSD’s development surfaced last week after a governance proposal outlining the stablecoin was briefly published online before being deleted. The launch has now been confirmed.

The introduction of mUSD comes at a time when stablecoins are gaining traction worldwide, with increasing use cases in payments, trading, and remittances.

Recent U.S. regulatory clarity, including the passage of the GENIUS Act, has further strengthened confidence in the sector.

MetaMask seeks to leverage these conditions by offering a stablecoin designed to integrate directly with its wallet infrastructure, allowing users to transact in a familiar environment while maintaining self-custody of their assets.

At launch, mUSD will be available on Ethereum and Linea, Consensys’ Layer 2 network. The token is expected to play a foundational role in the development of Linea’s DeFi ecosystem, supporting liquidity growth and network expansion.

mUSD will be integrated across the MetaMask suite of decentralized applications and DeFi protocols, supporting on-ramps, swaps, transfers, and cross-chain bridging directly from within the wallet.

By embedding these functions natively, MetaMask plans to streamline how users access stablecoin-based financial services.

In addition to DeFi functionality, mUSD is expected to support real-world payments by the end of the year. Through the MetaMask Card, users will be able to spend mUSD at millions of merchants worldwide that accept Mastercard.

This bridge between digital assets and everyday commerce reflects MetaMask’s strategy to expand beyond the crypto ecosystem into practical financial use cases.

By introducing mUSD, MetaMask positions itself at the intersection of self-custody, stablecoin adoption, and real-world utility.
