Yes, of course! aeUSD has a 100% collateralization factor, so you can use it to trade Aevo exactly as if it were USDC. Remember that Aevo's cross collateral structure always applies: the exchange will use your aeUSD to pay fees, fundings and liquidations unless you have also deposited USDC or USDT.

When you use aeUSD as collateral, your fees, losses and profits will be paid in USDC.
