# Vesting VOLT

Users will be able to vest their VOLT for up to 4 years duration to get veVOLT NFT.

The number of veVOLT per VOLT vested increases linearly until the maximum period of 4 years. The user gets; 

* 1 veVOLT per VOLT (lock duration of 4 years), 
* 0.75 veVOLT per VOLT (lock duration of 3 years), 
* 0.5 veVOLT per VOLT (lock duration of 2 years), 
* 0.25 veVOLT per VOLT (lock duration of 1 years), and so on.

User can manage the veVOLT NFT to; 

* **Increase the lock amount** - Higher veVOLT Voting Power 
* **Increase the lock duration** - Higher veVOLT per VOLT locked
* **Merge multiple NFTs** - Easier to attach NFT to staking to receive up to 2.5x boost

*Note 1: The lock duration can be extended only once per week* 

*Note 2: When a user extends lock duration, the veVOLT distribution is determined by keeping the start duration of the current lock.* 

*Note 3: When multiple NFTs are merged, the duration of merged NFT is the duration of the longest NFT before merge.*

When a user merges NFTs for the first time, the user has to undergo **3 approvals**; 

1. Allow the veVOLT for merge 
2. Reset any current veVOLT votes on gauges 
3. Merge veVOLT NFTs
