The MetaMask Money Account 6% APY Ends September 30

MetaMask is promoting a 6% figure alongside MetaMask Card this week. The product page is more specific than the promotion: up to 6% variable APY through September 30, and up to 4% APY afterwards. Both are described as variable and not guaranteed.

That end date is the part worth reading first, because the account it applies to is also where card cashback lands.

Cashback and yield stack on the same pool of money

MetaMask Card pays up to 3% back on eligible purchases, and that cashback is paid in mUSD directly into the Money Account. The same balance then earns the account APY. So the two rates are not alternatives to compare — they stack on one pool of money, and the spending rewards feed the yield position.

Deposits in USDC, USDT, DAI or aTokens convert to mUSD with no conversion fee, and MetaMask states there are no lockups, no withdrawal penalties and no account fees. For a card user, that removes the usual reason to keep a spending balance idle: the float between topping up and spending is earning.

It also means the balance funding the card and the balance earning yield are the same money, which is the detail that decides how to read the risk.

The yield comes from lending markets run by third parties

MetaMask is not paying the rate out of its own margin. Funds are deployed into blockchain lending markets, named as Aave and Morpho, through a set of third parties: Veda providing the infrastructure, Steakhouse handling monitoring, and Bridge, a Stripe company, issuing mUSD.

That structure explains the wording. A rate sourced from lending markets moves with borrowing demand, which is why "up to" and "variable" are doing real work here rather than being legal padding. The 6% is best read as a promotional level held to a date; 4% is the number the account is being described with after it.

MetaMask also states plainly that the balance is not insured by the FDIC or any government agency, and that losses are possible through smart contract failure or protocol exploit. For a savings account that is a disclosure. For a card balance it is a different thing: the money that clears a card transaction is sitting in DeFi lending positions until it is spent.

The UK and sanctioned countries are excluded

The Money Account is available globally with two exceptions named on the page: the UK, and countries on the US sanctions list. A UK cardholder reading a 6% headline is reading about a product they cannot open.

The rate applies to a balance, so only real float is worth holding

The rate applies to a balance, not to spending, so the amount worth holding is decided by how much float a card genuinely needs rather than by the headline. At 4% — the rate that survives October — a $2,000 spending balance produces about $80 a year, which is a different proposition from what 6% suggests when read in isolation.

The token underneath is the other thing to look at, since rewards and balance are both denominated in mUSD rather than in a currency; what mUSD is and who issues it is the same question as what the yield is denominated in. Tracked values for the card sit on the MetaMask Card page, and the rates above are as stated on the MetaMask Money Account page at publication.
