CRISP: Adjusting NFT Prices to Target a Steady Sales Rate
Summary
The Constant Rate Issuance Sales Protocol (CRISP) is a pricing mechanism for selling an ongoing supply of NFTs at a target pace. It tracks recent sales with an exponential moving sum (EMS), a recency-weighted measure that can be updated without storing a long history. The target sales rate can be translated into a target EMS, giving the mechanism a benchmark for assessing demand.
When observed sales exceed the target, CRISP raises the next purchase price more quickly as the gap grows. When sales fall below target, it lowers prices gradually, using a separate decay rate so that a temporary lull does not trigger an abrupt cut. The paper illustrates the behavior with modeled examples and describes a Python notebook and Solidity implementation, but the displayed formulas are incomplete in the supplied text. It provides no empirical evidence that the mechanism achieves a target rate in live markets; performance depends on demand responding to price as expected and on suitable parameter choices.
Key ideas
- CRISP uses an exponential moving sum to estimate recent NFT sales activity with recency weighting.
- A target sales pace is converted into a target EMS for comparison with observed demand.
- Prices rise more quickly when sales exceed the target, with the response controlled by a speed parameter.
- Prices decay gradually when sales are below target, limiting rapid reductions after slower periods.
- The examples are models, and the document does not establish live-market performance.
