The exact percentage of the pay out that will go to the stakers is yet to be determined, however it is expected that the majority of the pay out will go to the stakers. This is because the VeYFI part of the treasury will be used to reward stakers who contribute to the network by providing liquidity and staking their tokens. This will create an incentive for users to participate in the network and help it grow. Additionally, the VeYFI part of the treasury will also be used to buy back YFI tokens, which will help increase the value of YFI and reward those who already hold YFI tokens.
