MetaMask has launched a new self-custodial feature called Money Account, allowing traders to earn up to 4% variable annual percentage yield (APY) on mUSD balances while keeping funds accessible for spending and trading.
Integrated earning and spending
The Money Account combines earning, storage, and spending within a single interface. Balances generate yield automatically without staking or lockups, and can be used directly through a Mastercard-linked MetaMask Card. The feature also remains connected to MetaMask’s existing tools, including token swaps, perpetual contracts, and prediction markets.
The product is designed to make stablecoin balances productive without requiring traders to move funds across multiple platforms.
Infrastructure built on Monad
The system runs on Monad, a Layer 1 blockchain launched in November 2025. The network supports Ethereum-compatible smart contracts and offers performance metrics of up to 10,000 transactions per second, 400-millisecond block times, and near-zero fees.
Yield generation initially comes from Morpho vaults, with expansion to Aave planned. Current returns in similar decentralized lending markets range between 4% and 7%, suggesting the new account prioritizes convenience over maximizing yield.
The infrastructure was developed by Veda, while risk oversight is handled by Steakhouse Financial.
Stablecoin conversion and access
Supported assets including USDC, USDT, DAI, aUSDC, aUSDT, and aDAI can be converted into mUSD at a one-to-one ratio without fees. Traders can also purchase mUSD using debit or credit cards and Apple Pay.
The mUSD token, launched in September 2025, operates on Ethereum and Consensys’ Linea network. It currently holds a market capitalization of about $32 million, down from more than $100 million shortly after its debut. Daily trading volume is around $6.7 million, providing an early indication of liquidity.
Expanding into yield-bearing stablecoins
The launch places MetaMask into the growing market for interest-bearing stablecoins, which expanded by more than $20 billion in 2025. The move reflects a broader shift toward turning stablecoin reserves into usable, yield-generating assets.
MetaMask’s recent development strategy has focused on becoming a broader financial platform. Over the past year, it has added support for networks like Solana and Bitcoin, alongside features such as tokenized U.S. stocks, ETFs, commodities, and AI-powered wallet tools.
Key metrics to watch
Market attention is likely to center on several factors as the product rolls out:
- Growth in mUSD market capitalization as funds move into Money Accounts
- Changes in trading volume and liquidity for the token
- Monad network activity and its ability to handle increased usage
- Whether yields remain competitive with underlying lending protocols
Monad currently reports around 15,700 daily active users, making its performance under heavier demand an important variable. The evolution of mUSD supply and on-chain activity will provide early signals of adoption as MetaMask expands further into integrated financial services.
