In ousgInstantManager you can mint either rOUSG or OUSG using USDC and then redeem back to USDC. Both of these use an oracle to track the price of OUSG. This price can vary between when a transaction is sent to when it is executed. This can cause a user to mint or redeem at a different price than they intended.
Consider adding a minOut parameter for ousgInstantManager::mint and redeem calls.
