Hi @parkerburchett,
The strategy can indeed become illiquid if it reaches 100% utilization. Trying to withdraw from it will cause a revert.
These strategies are part of the Yearn V2 multi-strategy vault. Fortunately, other liquid strategies are placed earlier in the withdraw queue, ensuring that depositors can withdraw at all times.
Similar mechanics are built into the Yearn V3 infrastructure, with the distinction that single-strategy vaults are now also offered. These vaults have an availableWithdrawLimit
parameter, and trying to withdraw from them while the utilization of the underlying CDP is at 100% will also result in a revert.
How will will Aave Yearn strategy handle withdrawals when the Aave Utilization Rate is at 100%? When Utilization rate is 100% all the supplied assets have been lent out and there is no liquidity to redeem for the a tokens on Aave.
For example in the aWETH Strategy
Yearn Aave WETH address
0xfafEB6C262517d7d1171a3bA836E3e2d2897835f
that holds the aEthWETH. This Yearn Aave V3 strategy contract0xec2DB4A1Ad431CC3b102059FA91Ba643620F0826
On the Yearn website it says
Here is what Aave says about liquidity risk during high utilization rates.
If I have WETH deposited in this strategy but it can’t be withdrawn from Aave because the Utilization Rate is at 100% and I attempt to withdraw ETH from this strategy what will happen?
