MetaMask has launched Money Account, a self-custody savings and spending product built on the Monad blockchain that pays users up to 4% variable annual percentage yield on stablecoin balances.
This is all while keeping those funds available to spend at Mastercard merchants or deploy into DeFi trading, all without leaving the app. Consensys, MetaMask’s parent company, announced the product on June 30, 2026.
This news comes as MetaMask continues its attempt to regain market share in the world of decentralized crypto wallets, following the surge of Trust Wallet, Rabby, and others.

What MetaMask’s Money Account Actually Does
The account is built around mUSD, MetaMask’s proprietary dollar-pegged stablecoin, backed 1:1 by USD and short-term US Treasury bills held in reserve by Bridge, a Stripe-affiliated entity.
Yield is generated through a separate on-chain layer: when users opt in, deposits are automatically routed into decentralized finance (DeFi) lending protocols, specifically Morpho at launch, with Aave integrations planned to follow.
The APY is variable, net of all fees, and fluctuates with lending demand across those protocols. There are no lockups, no withdrawal penalties, and no account fees. Balances continue to earn until the funds are spent or moved.
Johann Bornman, MetaMask’s senior product director, clarified the structure: “Bridge holds the reserves (dollars and short-term Treasury bills) that back mUSD 1:1. The backing of the stablecoin reserve and its yield generation are separate systems.”

Money Account connects directly to the MetaMask Card, which runs on the Mastercard network and is accepted at hundreds of millions of merchants globally.
The Metal Card tier pays 3% cashback on the first $10,000 in annual spend (the card carries a $199 yearly fee); the standard virtual card pays 1%. Cashback is credited to the Money Account in mUSD.
Unlike most DeFi yield products that require manual protocol hopping, Money Account balances flow directly into MetaMask’s integrated trading suite, token swaps, perpetual futures, and prediction markets, without additional transfers.
The entire stack lives inside a single self-custody interface, meaning users retain control of their assets throughout, according to the Joe Lubin-led Consensys.
Joe Lubin, founder and CEO of Consensys and co-founder of Ethereum, framed the launch directly: “People build their wealth inside MetaMask, but until now they couldn’t keep it working here. With Money Account, that changes. Your balance earns the moment you add funds, and you can spend the moment you need to.”

Market Context and Risks Worth Knowing
The stablecoin market has grown to more than $320Bn, according to MetaMask, and the race among crypto wallet providers to become full financial platforms, bundling stablecoin yield, payments, and trading, has intensified sharply heading into 2026.
MetaMask’s mUSD competes in an increasingly crowded field of dollar-pegged assets; for a wider view of that landscape, Circle’s USDCx deployment illustrates how stablecoin liquidity infrastructure is scaling across chains.
Retail users should weigh several risks before depositing. Smart contract vulnerabilities in Morpho, Aave, or the underlying vault infrastructure could result in partial or total loss of funds.
MetaMask’s own disclosures explicitly flag this. The 4% APY is not guaranteed and can compress quickly if DeFi lending demand softens.
mUSD also carries issuer and custodian risk tied to Bridge; Monad carries network risk as a relatively new Layer 1 blockchain, and yield earned will likely be treated as taxable income in most jurisdictions.
Money Account is available globally through MetaMask Mobile v8.0 and above, except in the UK and jurisdictions on the US sanctions list.
