Key Metrics

Information


- Code reviewed by at least one experienced auditor; [CertiK](https://www.certik.com/projects/tarot) audited in August 2022
- Anonymous team reduces transparency
- No documented protocol hacks since launch
- Poor mechanisms to mitigate oracle price manipulation


- Core protocol launched in 2021; maturity over a year reduces technical risk as smart contracts are moderately battle-tested
- Top 20% by total value locked slightly reduces risk
- Decentralized governance increases transparency
- At least one critical governance issue documented


- No concerns identified
- Isolated markets enable asset risks to be contained to each individual pool without impacting the entire protocol

Risk Assessment

Tarot is a decentralized lending protocol where users can participate as lenders or borrowers in isolated lending pools.

What we like

The protocol uses Uniswap V2 time-weighted average price (TWAP) as its price oracle, which is more susceptible to manipulation.

What we like less

Offers you a simple way to earn an additional yield on top of your LP tokens through leveraged yield farming.

Summary

#### How Tarot works
Tarot is a decentralized lending protocol built on Fantom and Optimism. The smart contracts for lending pools are forked from Impermax. The core contracts consist of the Factory and Deployer contracts for each lending pool. Anyone can create a lending pool via the Factory, and all lending pools are isolated. This means that if a borrower gets liquidated in one pool, it does not impact any other lending pools. Each lending pool on Tarot has an associated decentralized exchange and token pair. All lending pools consist of three parts: an interest-bearing contract for the first token in the token pair (Borrowable0), an interest-bearing contract for the second token in the token pair (Borrowable1), and a collateral contract for the LP token (Collateral). Lenders can deposit either token0 or token1 into a Borrowable contract. In exchange, they receive interest-bearing bTAROT tokens, which represent the underlying token plus accrued interest. Borrowers deposit LP tokens as collateral into the Collateral contact to create loans, provided there is sufficient liquidity available. To enable leveraged yield farming, Tarot uses tokens from Borrowable0 and Borrowable1 to add liquidity to the decentralized exchange for the token pair. Borrowers receive cTAROT tokens in return that represent the borrower's initial collateral plus borrowed LP tokens. Lastly, Tarot Supply Vaults are lending aggregators that use automated strategies to earn yield across multiple Tarot lending pools. Users who deposit into Supply Vaults receive tTokens in return that represent a share of the underlying tokens in the vault.
#### How Tarot makes money
Tarot charges two types of fees paid by borrowers to lenders. There is a fixed, one-time borrow fee of 0.1% whenever a new loan is taken out. Currently, 10% of the borrow fee is reserved by Tarot and allocated to the protocol reserves as bTAROT tokens. In addition, there is interest on borrowed tokens that accrue over time. Lenders do not pay any fees for supplying tokens, nor any deposit or withdrawal fees. Lastly, Tarot charges a 10% performance fee on yield earned through its Supply Vaults. These fees are allocated to the protocol reserves as tTokens.
#### How you make money on Tarot
You can make money by depositing LP tokens on Tarot to earn leveraged yield farming rewards. Lenders can deposit assets to accrue borrowers' interest. Lastly, you can also deposit assets into Supply Vaults to earn lending interest across multiple Tarot pools.
