Polycat Finance has a unique burning mechanism with a "Burning vault" where deposit fees are staked and 100% of its yields are used to buyback and burn their native token, FISH. On top of this 5% of all the other vaults' earnings are used for the same purpose. With a 3 million max. supply cap (which is estimated to be reached in August 2021), Polycat Finance has stood out from the rest on Polygon. Farms and pools have been audited by TechRate, vaults have been audited by Obelisk.
