The curve is a mathematical function that calculates the swap amount. In Uniswap, the curve is a constant product formula
x×y=k
, which implies
(x+Δx)(y+Δy)=k
, thus given
Δx
one can calculate
Δy
and vice versa.
In Integral SIZE, the curve is a constant swap function, meaning that it always fills the order at the oracle TWAP price, regardless of order size. Therefore, there is no price impact.
