MetaMask Launches Wallet-Native Stablecoin mUSD to Bridge TradFi and DeFi

MetaMask's new stablecoin, mUSD, went live on September 15, 2025, marking a significant step in simplifying crypto transactions for users. The wallet-native asset, pegged 1:1 to USDC and USDT, enables seamless onramping, holding, earning, and spending within the MetaMask ecosystem.

Powered by Transak, mUSD is initially available to users in the U.S. and EU. The stablecoin serves as a bridge between traditional finance and DeFi, supporting activities like trading, lending, and remittances. It integrates natively with MetaMask Swap and Bridge, while the MetaMask Card expands utility to over 150 million global merchants.

With $18.01 million market capitalization at launch, mUSD demonstrates immediate traction. The asset trades within a tight $0.99-$1.01 range, backed by strong liquidity on LineaBuild and low-cost fiat onramps. This launch coincides with enhanced wallet functionality for asset management and funding.
