MetaMask has launched Money Account, a self-custodial account that lets users earn up to 4% variable APY on stablecoin balances while keeping funds inside the MetaMask ecosystem.
The product uses MetaMask USD, or mUSD, the wallet-native dollar stablecoin introduced last year. Users can deposit supported stablecoins such as USDC, USDT and DAI, which convert into mUSD at 1:1 parity with no conversion fee. Other tokens can also be deposited, but MetaMask applies a conversion fee when assets outside the supported stablecoin set are swapped into the account.
Money Account is designed to make idle balances productive without sending users through separate DeFi apps. Once a user opts in, the balance begins earning automatically, with no lockups, withdrawal penalties, account minimums or manual staking steps. The APY is variable and not guaranteed, with returns reflected in the Money Account balance.
The launch extends MetaMask’s earlier stablecoin plan, where mUSD was positioned as a wallet-native dollar asset for holding, trading, payments and rewards. MetaMask had already linked mUSD incentives to its $30 million rewards program, making the stablecoin a central part of its user-retention strategy.
Money Account sends funds through third-party smart contract vaults into DeFi lending markets. The initial allocation goes to Morpho, with Aave markets planned to follow. Vault infrastructure is built and operated by Veda, while Steakhouse Financial curates risk for the strategy.
The product is built on Monad, giving MetaMask a high-throughput network for wallet-native yield, trading and spending flows. MetaMask says users can trade, send, save and spend from the same account, turning mUSD into a working balance rather than a passive stablecoin position.
The account also connects directly to MetaMask Card. Users can spend from the same wallet environment at Mastercard-accepted merchants, with crypto converted at checkout. MetaMask Card support has already expanded across several networks and assets, including mUSD, after a recent rollout to 13 more Latin American countries.
The structure keeps custody with the user, but it does not remove smart contract, lending-market or stablecoin risk. MetaMask says the account is self-custodial, meaning the user’s private keys control the Money Account balance, while the yield component depends on external vault and DeFi infrastructure.
The launch pushes MetaMask further beyond swaps and wallet storage. Money Account combines stablecoin conversion, DeFi yield, trading access and card spending into one interface, giving users a crypto-native version of an interest-bearing spending balance.
The product arrives as stablecoin competition is shifting toward payment utility and distribution. Coinbase and Spiko recently opened stablecoin access to tokenized UCITS money-market funds, while payment and wallet providers are trying to turn stablecoins into everyday cash-management tools rather than only exchange liquidity.
MetaMask’s advantage is direct wallet distribution. Users already holding stablecoins inside the wallet can convert into mUSD, earn variable yield, trade through MetaMask and spend through MetaMask Card without moving through a centralized exchange.
Money Account is live inside MetaMask, with up to 4% variable APY shown on mUSD balances, Morpho as the first lending destination, Aave planned later and MetaMask Card available for supported users.
