How lending pool (LP) tokens work
Lending Pool tokens (or "LP tokens") are tradable ERC-20 tokens that represent a lender’s proportional representation in the pool.
In the beginning, when no loans have been disbursed by the TrueFi lending pool, lenders will receive one TrueFi Lending Pool Token (tfTUSD, tfUSDC, tfUSDT, or tfBUSD) for every stablecoin lent to the pool.
As the pool starts earning yields and disbursing loans, the value of the pool tokens may increase or decrease depending on returns within the pool. The value of the pool represents the present value of all its underlying tokens (stablecoins, loan tokens, and other tokens earned).
We can calculate LP token price by checking the
totalSupply()read functions on the lending pool smart contract:
LP token price = poolValue() / totalSupply()
We can use this LP token price to find how many LP tokens a lender will receive in return for lending tokens to the pool.
Additionally, we can calculate the value of a lender's position at any point in time:
Lender's position value = (# of LP tokens held) * (LP token price)
Yes, LP tokens can be traded on secondary markets. There are existing markets on Uniswap v3 today.
LP token prices calculated by the lending pool assume that loans will be repaid successfully within the term, among other assumptions.
Other market participants may have use different assumptions in their calculation of LP token prices. There are several market factors that may govern the price of lending pool tokens and the TrueFi platform does not have any control over them.
