You can supply USDC into to Aave and receive the equivalent aUSDC by calling the `supply()` [function ](https://docs.aave.com/developers/core-contracts/pool#supply)in the Pool contract. You need to already have USDC in your wallet. The documentation shows you will need e.g. `lendingPoolContract.supply`(`usdcAddress`, `usdcAmount`, `addressToReceiveATokens`, `referralCode`) To call `supply(),` the Aave pool contract should be able to move your tokens on your behalf, otherwise the contract can't supply your tokens. So you must `approve()` (or `permit `for Aave v3) the contract to supply your tokens first. `Approve() `is a function from any ERC20 token so you can use that.
