How Bonding Curves Work

A bonding curve is a mathematical curve that defines the relationship between a token's price and its supply. In this application:

• The price increases as more tokens are purchased (positive slope)
• The price decreases as tokens are sold back to the curve
• The formula used is: Price = InitialPrice + (Slope * Supply)

This creates a fair and transparent pricing mechanism that automatically adjusts based on demand.
