KIF is a bit similar to YFI. It's the governance token of KittenFinance:

• for the DAO governing KittenSwap
• dividends from KittenSwap fees
• buybacks from KittenSwap fees
• governing and receiving dividends from future projs such as vault, lending, etc.
• the total supply of KIF is fixed at 42000 (21000 in first week, halving every week)
• you'll be able to stake KIF for other projects, just as you can stake YFI for various projects
