The concept of an early unlock fee is not new within DeFi, acting as a safety net to encourage users to stay in the ecosystem. With Vesper, this early unlock fee is the penalty you would pay if you decide to unlock your VSP before the end of your chosen lock-up period. The initial penalty starts at 50%, and decreases linearly over time until the lock expires when it becomes 0%. Any penalty fees collected in this way go back to the Vesper DAO Treasury.

How does it work?

To determine the penalty involved in an early unlock, you can use the following formula:

User’s Locked Balance * Remaining Time * Maximum Penalty / Total Lock Duration


Let’s say you locked your VSP for 1 year, but after 6 months, you decided to withdraw them early.

Given the penalty decreases linearly from 50% to 0% over the course of the lock duration (1 year in this case), at the halfway point (6 months), your penalty would be 25%.

If you had locked 100 VSP, you’d pay 25 VSP as a penalty for unlocking them early.
