What is MetaMask's mUSD Stablecoin?

mUSD Basic Features

mUSD is a stablecoin that maintains a 1:1 value with the U.S. dollar.

Each token is backed by U.S. Treasury bills held in segregated accounts.

Unlike USDT and USDC, mUSD plans to share some treasury yield with users, a feature that could change how people think about holding stablecoins.

The token uses standard ERC-20 architecture, making it compatible with existing DeFi protocols and exchanges.

Users can mint mUSD by depositing dollars or other accepted stablecoins through MetaMask's interface.

Technical Specifications

Token Standard: ERC-20 on Ethereum
Backing: 1:1 with U.S. Treasury bills (0-180 day maturity)
Redemption: Direct conversion to USD through MetaMask
Audit Schedule: Daily attestations planned
Cross-chain Plans: Arbitrum, Optimism, Polygon, Base

The Power Players Behind mUSD

MetaMask's Position

MetaMask, owned by ConsenSys, processes billions in transaction volume monthly.

The wallet's dominance in the Ethereum ecosystem gives mUSD immediate access to millions of active DeFi users.

Bridge (Stripe) - Payment Infrastructure

Stripe acquired Bridge for $1.1 billion in February 2025, marking the payments giant's biggest crypto move to date.

Bridge handles:

Fiat-to-stablecoin conversions
KYC/AML compliance
Payment processing infrastructure

The protocol allows multiple entities to mint stablecoins while maintaining consistent standards and interoperability.

M^0's role includes:

Mint and burn mechanisms
Yield distribution systems
Cross-chain coordination

The protocol raised $35 million from Bain Capital Crypto and operates with former MakerDAO and Circle team members.

Blackstone - Treasury and Custody

Their involvement brings traditional finance credibility to the project.

Blackstone manages:

U.S. Treasury bill investments
Asset custody services
