MetaMask unveiled the Money Account, a self-custodial account that automatically earns up to ~4% APY on its mUSD stablecoin as you trade, send, and spend.

Funds spend worldwide via the MetaMask Card with up to 3% back, and deposits in mUSD, USDC, USDT, or DAI carry no conversion fees.

mUSD is backed 1:1 by USD and short-term Treasuries via Bridge, a Stripe company. The account is rolling out now on MetaMask Mobile.
