Impermanent Loss
Drag the price ratio and watch an LP's divergence loss against simply holding.
IL = -2.02%
HODL $12500.00 vs LP $12247.45 (Δ $-252.55, fees excluded)
P = 1.5000× · $10,000 initial position
Price Impact
See how trade size relative to pool depth drives slippage on a constant-product curve.
10% of reserve
Price impact ≈ 11.1%
Constant-product (x·y=k): impact = f / (1 − f). The deeper the pool relative to your trade, the smaller f — and impact stays near zero.
Interest Rate Curve
Move utilization across the kink and watch a lending pool's borrow rate respond.
U 80%
Rate = 10.00%
Below kink — gentle slope (base + U × m₁)
Concentrated Liquidity
Set a v3 price range and see how capital splits between the two assets.

PT Pull-to-Par
Watch a Pendle principal token's price converge to par as maturity approaches.
r=5%: PT starts at 0.9524 · r=10%: PT starts at 0.9091 · r=20%: PT starts at 0.8333 — all converge to 1.00 at maturity (pull-to-par).
