Tarot is a decentralized lending protocol on Phantom Opera where users can participate as lenders or borrowers in isolated lending pools.
Lenders can supply tokens to any lending pool in the Tarot Protocol to earn passive yield without impermanent loss. Borrowers can deposit LP tokens in a lending pool to borrow additional tokens in the token pair. This enables borrowers to leverage their LP tokens for even more LP tokens, allowing for leveraged yield farming and enhanced LP rewards.
Tarot is a decentralized lending protocol where users can participate as lenders or borrowers in isolated lending pools. The Tarot Protocol facilitates a new kind of leveraged yield farming experience for borrowers, with enhanced farming and vault rewards, while enabling lenders to earn significant yield on supplied tokens without the risk of impermanent loss.
Liquidity providers supply tokens to decentralized exchanges (DEXs) and other DeFi protocols.
When you provide liquidity to a DEX, you receive LP tokens as proof of contribution. For example, if you supply FTM and TAROT to a DEX, you will receive FTM-TAROT LP tokens in return. These LP tokens represent your proportional share of the total liquidity in the DEX for the token pair.
Whenever anyone swaps or trades on the DEX, a small trading fee is accrued to the liquidity pool as a reward for liquidity providers.
Liquidity providers on automated market maker (AMM) DEXs such as SpookySwap and SpiritSwap earn yield from transaction fees and possibly staking rewards. Tarot enables borrowers and lenders to significantly dial up (or down) the risk (and rewards) of this yield, respectively.
DEXs sometimes offer farms or staking pools allowing liquidity providers to stake their LP tokens and earn additional reward tokens. These farms provide an additional incentive to liquidity providers and help to offset the risk of impermanent loss.
Impermanent loss is one of the principal risks associated with being a liquidity provider.
The value of an LP token is always backed 50-50 by the underlying tokens in the token pair. Due to the nature of AMMs / constant-product market makers to uphold this ratio, a significant swing in the price of the underlying tokens relative to each other can result in a greater loss to liquidity providers compared to simply holding the tokens, assuming the liquidity is removed at that moment. (Hence, the loss is “impermanent.”)
Leveraged yield farming is a mechanism in Tarot that allows liquidity providers to use their LP tokens to borrow and acquire more LP tokens, with the expectation that the rewards from having more LP tokens (adding more liquidity to the DEX and earning additional yield and farming rewards) will exceed the borrowing cost.
Tarot’s unique LP token collateralization model and liquidation mechanics enable significantly leveraged yield farming positions. The risk of impermanent loss is also amplified with leveraged yield farming.
Lenders in Tarot indirectly provide liquidity by making their tokens available to borrowers for leveraged yield farming. Lenders do not risk impermanent loss with their supplied tokens, as the risk of impermanent loss is transferred to borrowers in the Tarot Protocol.
Total value locked (TVL) is a useful metric for DeFi protocols. TVL measures the amount of tokens locked in a protocol at a given time. Tarot includes the following elements in TVL calculations:
* Total collateral in lending pools (including initial collateral and leveraged positions)
* Total excess supplied tokens (i.e. that are not borrowed, since borrowed tokens are already accounted for in total collateral or not locked in the protocol)
A price oracle is any contract that provides on-chain access to price information for a token, usually denominated in terms of another token or an off-chain unit of account. Virtually every decentralized lending protocol requires timely and accurate on-chain prices in order to determine the value of collateralized loans, as well as to prevent borrowers from withdrawing more than the value of their collateral at any time.
