Crate pallet_exchange[−][src]
Exchange Module
Exchange NFTs or FTs.
For pool, use bancor curve. y = m * x ^ n r = reverseRatio = ppm / 1000000 after integral and simplify, can get these formula buy: p = poolBalance * ((1 + amount / totalSupply) ** (1 / (reserveRatio)) - 1) sell: p = poolBalance * ( 1 - ( 1 - amount / totalSupply ) ** (1 / reserveRatio)) current price = poolBalance / (totalSupply * reserveRatio) when supply is 0, p = reserveRatio * m * amount ** (1/reserveRatio) Thanks for the explanation in Slava Balasanov’s article (https://blog.relevant.community/bonding-curves-in-depth-intuition-parametrization-d3905a681e0a)
