Variable Rate Gradual Dutch Auctions are a new model for NFT distribution. It provides a way to issue NFTs using nearly any schedule while allowing users to seamlessly buy them at any time. The mechanism works by raising prices when sales are ahead of schedule and lowering prices when sales are behind schedule. If sales are perfectly on schedule, the price to buy the next one will remain the same.
This model was designed by the Paradigm team and has been initially used in 2 projects: Art Gobblers & 0xMonanco.
