# asdPENDLE Vaults **What is asdPENDLE** asdPENDLE represents the compounding sdPENDLE in the StakeDAO PENDLE Locker. The total amount of asdPENDLE contained in the compounder is equal to the total sdPENDLE balance multiplied by the current index: sdPENDLE\_Balance =asdPENDLE\_Balance \* Current\_asdPENDLE\_Index Using asdPENDLE to represent a share of the underlying compounding sdPENDLE vault simplifies the smart contracts and is more gas efficient. The asdPENDLE compounder has been upgraded and is now fully liquid, allowing instant withdrawals and further integrations with money market protocols. **What is veSDT delegate** By delegating veSDT to asdPENDLE vault, users’ sdPENDLE reward will be boosted up to 2.5X.
