MetaMask has introduced Money Account, a new self-custodial product within its wallet that allows users to earn up to 4% APY on mUSD stablecoin holdings. Funds can also be used for payments via the MetaMask Card and other on-chain services.
Users only need to deposit mUSD into a Money Account to begin earning yield. According to MetaMask, the product does not require staking, asset lockups, or any additional manual actions.
Money Account is built on Monad, which will serve as its primary network. Initially, yield will be generated through Morpho vaults.
Consensys CEO Joseph Lubin said the crypto user experience has long remained fragmented, requiring separate services for trading, earning yield, and making payments.
Balances can also be used across other MetaMask services, including token swaps, perpetual trading, and prediction markets.
The company said the new product is designed to reduce liquidity fragmentation by allowing users to earn yield and make payments without moving assets out of their wallet.
MetaMask allows users to convert supported stablecoins – including USDC, USDT, DAI, aUSDC, aUSDT, and aDAI – into mUSD at a 1:1 ratio with no conversion fee. Users will also be able to purchase mUSD using debit cards, credit cards, and Apple Pay.
The mUSD stablecoin launched on Ethereum and Linea in September 2025. According to the project's website, its market capitalization currently stands at around $32 million, although it exceeded $100 million shortly after launch.
Earlier, Chainlink joined Project Pangea, an initiative involving 47 banks from Europe and South Korea that aims to accelerate cross-border settlements using regulated stablecoins.
