Spend and earn with MetaMask Card
mUSD is the official token of MetaMask Card. For every eligible transaction on MetaMask Card, you’ll earn 1% mUSD back, or 3% mUSD back with the Metal card.
You can easily fund your card with mUSD on MetaMask Mobile. Simply click the card icon in the top-right of the screen, and click ‘Change Asset’ to set a spending limit for mUSD.
Lend mUSD
You can lend mUSD on Ethereum Mainnet and Linea with Aave’s lending markets for rewards.
When you lend mUSD, your loaned tokens will begin earning rewards daily. The loaned tokens will leave your account until you claim them, and in the meantime, you will receive an equivalent number of amUSD tokens.
Think of amUSD as a receipt for your loaned mUSD. Each amUSD token represents an mUSD token that you loaned at a 1:1 ratio, and returning amUSD allows you to withdraw your loaned mUSD at a 1:1 ratio.
For example, if you lend 100 mUSD, you'll receive 100 amUSD to hold until you're ready to withdraw your loaned mUSD. When you withdraw, you'll enter the amount of amUSD you want to return, such as 50 amUSD, and you'll receive 50 mUSD in return.
As your loaned mUSD earns rewards, the amount of amUSD you hold will automatically increase to reflect the rewards earned.
You can trade your amUSD. For more information on aTokens, see our guide here.
When you’re ready to stop earning rewards and withdraw your loaned mUSD, you can do so at any time. From the aToken details page, click ‘Withdraw’.
You can see the amount of that token you have loaned; if you’d like to select another token, click the dropdown menu.
