Aave's proposed USAT gateway would require approval for every return swap

• —Each swap needs approval in both directions and can be revoked after the deposit-for-GHO exchange
• —Reserve funding is 65M GHO, module draw limit 25M GHO, waUSAT exposure cap 20M
• —GHO stays freely transferable, but recovering waUSAT depends on Aave withdrawal and Anchorage redemption
• —Swap fees are set at zero; Anchorage charges 10 bps for USAT redemption
