Stable Earner Interest Rate Model Contract

$earnerRateModel.rate()$

• Returns current earner rate in basis points: $P1 * e^{r1 * t} - P1 = P2 * e^{r2 *t} - P2$

  • If $totalActiveOwedM <= totalEarningSupply$, $r2 = minterRate * totalActiveOwedM / totalEarningSupply$,

  • Otherwise, calculates equilibrium rate $P1 * e^{r1 * t} - P1 = P2 * e^{r2 *t} - P2$ $r2 = ln(1 +( P1 *e^{r1 * t} - P1) / P2),$ $P1=totalActiveOwedM$, $P2=totalEarningSupply$, $t=confidence\;interval$

  • Returns $min(baseEarnerRate,MULTIPLIER * r2)$, where $baseEarnerRate$ and $minterRate$ are APY in basis points.
