input | uint256 | x | unsigned 256-bit integer number |
output | uint256c | cX | Return cubrtu(x) rounding down, where x is unsigned 256-bit integer |
Determine supply bottom
Integrate over the curve, and solve for supply top
supplyNOM_Top = a(3ETH/a + (supplyNOM_Bot/a)^3)^(1/3)Subtract supply bottom from top to get NOM for ETH
Input/Output | Data Type | Variable Name | Comment |
input | uint256 | amountETH | amount of ETH to buy wNOM |
output | uint256 | amountNOM | Buy Quote for the purchase of wNOM based on the amount of ETH (Dec 18) |
Determine supply top:
priceBondCurve - 1% = Top Sale PriceIntegrate over the curve to find ETH:
ETH = a/3((supplyNOM_Top/a)^3 - (supplyNOM_Bot/a)^3)Subtract supply bottom from top to get NOM for ETH
