MetaMask has introduced Money Account, a new feature allowing users to earn up to 4% annual percentage yield (APY) on mUSD stablecoin holdings. mUSD is a MetaMask-native stablecoin pegged to the US dollar and backed by US Treasury bills, providing a safer collateral base. The yield is generated through Morpho vaults on the Monad blockchain, an EVM-compatible high-throughput chain. This move transforms MetaMask from a simple wallet to a yield-bearing platform, competing with traditional savings accounts but with different risk profiles due to DeFi smart contract risks.
