## Deposit with discount and lock

Deposit DAI into the vault in exchange for a gNFT, which represents rights to locked gDAI. 

Discount percentage is based on the current collateralization ratio of the vault and the duration the staker is willing to lock gDAI for.

You can deposit at anytime.

See [#gNFT](https://gains-network.gitbook.io/docs-home/liquidity-farming-pools/gdai-vault#gnft) in overview.

Current maximum discount: 5%

Current lock window: \[7d, 365d]

## Unlock

gNFT holders are able to claim gDAI anytime after the unlock date by unlocking through the UI. This function burns the NFT and transfers gDAI to owner's wallet.

## Withdraw Request

Make a withdraw request for any amount of unlocked gDAI.

## Withdraw

When a withdraw request's epoch is the active epoch, the requested amount may be redeemed. If the epoch window is missed, the request becomes invalid and a new request must be made.

This can only be done during the withdraw window of an epoch.

See [#Withdraw-Locks](https://gains-network.gitbook.io/docs-home/liquidity-farming-pools/gdai-vault#withdraw-locks) in overview.
