Torch allows you the option of getting rid of the 14-day unstaking period for a fee. By signing up and staking your ZILs via Torch you are able to make use of this feature. Currently Torch is the only wallet that allows you to instantly unstake your staked ZIL.
Can I instantly unstake part of my stake?
No. As of now, the feature of Instant Unstaking can only be used for the full amount you have staked inside your wallet.
