# Supply curves ## Supply Curves In Doppler, **supply curves** define how token price changes relative to the amount sold during a price discovery auction. Instead of a single fixed price, a supply curve maps cumulative tokens sold to price, allowing controlled, potentially predictable price progression as demand unfolds. *** ### What a Supply Curve Does * Determines **how price increases** as tokens are purchased * Shapes **auction dynamics** (early cheap access vs. steep climbs) * Signals **scarcity and demand** to participants * Influences **liquidity migration outcomes** A well-designed curve aligns economic incentives and supports efficient market formation. *** ### Curve Types Supported Doppler supports multiple supply curve models to fit different launch goals: #### Static Supply Curves Flat or linear progression with a single supply curve.\ Price increments are uniform as tokens sell. > Useful for simple, predictable price growth without complex structure. *** #### Multiple Supply Curves Multiple segments of the same market with distinct slopes.\ Each segment can have a different price rate. > Lets projects encode phases (e.g., early discount → steeper later pricing). *** #### Dynamic / Time-Based Supply Curves Curve parameters evolve over time or based on demand signals.\ Price can accelerate or decelerate dynamically. > Ideal for launches that need tempo-aware pricing behavior or maximum efficiency. *** ### Designing Good Curves * Gentle slope → smoother, more gradual price movement * Steep early slope → faster price growth, tighter early access The choice of curve impacts: * Token distribution speed * Participant experience * Initial liquidity depth Supply curves are a core economic primitive in Doppler - they convert demand into predictable pricing, designed to be easily updatable and enabling iterations towards an ideal market structure. *** ### When to Choose Which Curve * **Static** → Simple, predictable auction * **Multicurve** → Phased launches with differentiated pricing. Well suited for low value assets. * Multicurve is considered a *strict* improvement over static due its designs ability to implement a superset of static's functionality and should be used on supported networks. * **Dynamic** → Demand/time-sensitive markets. Well suited for high value assets. Custom supply curves offer flexibility for projects to design markets tailored to their use cases, without custom contracts - all defined and adjustable in simple configurations at launch time. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
