The Fountain is where users can lock VNO to receive VNO incentives. Users can choose between lock durations of 3-months, 12-months, 48-months, and 96-months to lock their VNO. The longer the lock duration, the larger the proportion of VNO emissions for the users.
Here is the multiplier amount as well as the exit penalty corresponding to different vaults:
Exit penalty on the amount of VNO that user is exiting
% of penalty to other lockers
% of penalty to treasury
Note: For exit penalty paid to other lockers, it will be automatically locked into the 96-month vault and it needs to be claimed by other lockers. The amount that each remaining lockers' get is determined by their weighted share of # of VNO locked * Vault multiplier.
