Solar Vault is a set of time locking pools, with higher incentives. Long term $SOLAR supporters can lock their tokens for a pre-determined set of time, for higher rewards. Currently, there are 7 day and 30 day lockups, as well as a lower APY pool without any timelock.
Participants receive various rewards, including: higher rewards during lock duration, higher allocations in the Launchpad, and more.
Every time you stake or claim rewards your lock time renews.
