The pools below are the old V1-V2.1 ones.

How was APY calculated in V1-V2.1?

Capital is required for traders and farmers to get leverage for their financial operations. For this, there are Liquidity Pools: anyone can become a liquidity provider by supplying assets in the Liquidity Pool. The profitability of LPs depends on the pool utilization ratio U - the higher utilization, the higher interest rate. See a bit more on the Protocol Fees page.

Borrow APY is calculated according to formula

r(t)={r0+U(t)U1(r1r0),U(t)U1r1+(U(t)U2)r2r1U2U1,U(t)(U1,U2].r2+(U(t)U2)r3r21U2,U(t)>U2.r(t) = \begin{cases} r_0 + \frac{U(t)}{U_1}\left(r_1-r_0\right), & U(t) \le U_1\\ r_1 + \left(U(t)-U_2\right)\frac{r_2-r_1}{U_2-U_1}, & U(t) \in (U_1,U_2].\\ r_2 + \left(U(t)-U_2\right)\frac{r_3-r_2}{1-U_2}, & U(t) > U_2.\\ \end{cases}

Latest update: pool limits are effectively lifted. Any actual caps are just required by the architecture to have *some* number and can be lifted without a vote if the TVL approaches them. As for the min-max personal borrow limits, they have been established by another vote: GIP-21, then GIP-71.
