MetaMask's Money Account Offers Up to 4% Yield on Stablecoin Balances

MetaMask has launched Money Account, a self-custodial account that lets users earn up to 4% variable APY on mUSD balances within the MetaMask ecosystem. The product uses MetaMask USD (mUSD), the wallet-native dollar stablecoin introduced last year. Users can deposit supported stablecoins such as USDC, USDT and DAI into their Money Account, which convert into mUSD at a 1:1 parity with no conversion fee.

The launch extends MetaMask's earlier stablecoin plan, where mUSD was positioned as a wallet-native dollar asset for holding, trading, payments, and rewards. Money Account sends funds through third-party smart contract vaults into DeFi lending markets, starting with Morpho Vaults, followed by Aave markets.

Morpho Vaults are built and operated by Veda, while Steakhouse Financial curates risk for the strategy. The account is built on Monad, giving MetaMask a high-throughput network for wallet-native yield, trading, and spending flows. Users can trade, send, save, and spend from the same account, turning mUSD into a working balance.
