aave
Allow `withdraw` function to be called on behalf of some account.
Currently all interactions with the pool can be done onbehalf of another account (modulo approval), except withdraw.
This makes it gas costly for a protocol managing user's funds on AAVE because it needs to transfer overlyings from the user's account to the protocol's account before being able to withdraw. Unless there is a good reason not to do this (i'd be curious to know), in general it is a nice feature that all functions that pull funds from a protocol (here, borrow and withdraw) can be done 'onBehalf' and 'to' some accounts (with the required approval).
@jkrivine How would you give allowance to someone to withdraw on your behalf?
@jkrivine How would you give allowance to someone to withdraw on your behalf?
well, you can borrow on someone's behalf by using a special approval of the debt token, a similar scheme could be used on aToken using an approveDelegate function. When a delegatee wants to withdraw on delegator's behalf the logic would need to check that:
- Allowance is enough to withdraw
- the health factor of the delegator's account permits the withdrawal

The concept is straightforward, but I think a "withdraw on somone's behalf" does not bring value. As a user:
- I can send directly my aToken to another user so he can withdraw
- I can approve another user, so I can still earn yield until he pulls and withdraws.
I suggest you to open a thread in the governance forum so the community can discuss about it
