Protocol Math

All math on Finterest is done using integers. All assets have a token decimal cutoff that represents the smallest decimal unit of that asset. For example the ICP token has 8 decimals. If you want to signify 5.2 ICP you need would enter in 520_000_000 as into the protocol. See below for other assets and token decimals. Liquidity is denominated in USD with 8 decimals.
