aUSDC is used to represent the amount of USDC supplied to the Aave market and the interest earned on those assets. When users supply USDC to the Aave LendingPool, they receive an equivalent amount of aUSDC, which will start accruing interest immediately. The balance of aUSDC held by a user includes both their principal balance and the yield generated by the principal balance, and it can be checked at any time using the balanceOf method. Users can withdraw their original assets from the LendingPool by burning the corresponding amount of aUSDC​.

In addition, aUSDC can be transferred to other accounts. However, it's important to note that by transferring aUSDC, users are transferring their balance of the underlying USDC asset. Only the account holding the aUSDC can withdraw the deposited asset. Also, it's worth mentioning that the liquidity rewards earned prior to the transfer of aUSDC are accrued by the user/address holding the aUSDC originally, but all future liquidity rewards will be earned by the new recipient​.
