# Finny Finny is a decentralized lending and borrowing protocol hosted on the Internet computer. Our canister principal is listed below: ``` z4viz-kiaaa-aaaal-qbxmq-cai ``` ## How it works visualized ## Protocol Math All math on Finny 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. ## Assets | fToken | fToken Decimal | Underlying | Underlying Decimal | | ------ | -------------- | ---------- | ------------------ | | fICP | 8 | ICP | 8 | | fCkBtc | 8 | CkBtc | 8 | | fXTC | 8 | XTC | 12 | ### Notational Token (Not for Lending or Borrowing Just for Liquidity Displays) | Token | Decimal | | ----- | ------- | | USD | 9 | ## Exchange Rate The exchange rate is given by the amount of tokens one would receive for 1 underlying token. $$ exchangeRateMantissa\_{n} =\\\frac{ (totalCash\_{n}+totalBorrows\_{n}-totalReserves\_{n})\*mantissa}{totalfTokenSupply\_{n}} $$ --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
