@rishi556 in a Airdrop the other 250 ENG to generate a list (which is a CSV) is optional. it will generate the list of users at your given parameters, for example on the stakes of PAL, you can set min and max stakes and a Total Reward pool, it will generate a file Distributing all the reward pool with shares in Stake, its only when you want to generate a accurate list based on stakes of other tokens. users can provide there own list. so a Claim-drop is 250 ENG & Airdrop is 50 ENG / 1000 users.
