BPEG'd Smart Oracle

Floor prices for NFT collections are provided by a custom built oracle that aggregates several price data feeds layered on Chainlink. Custom built and fit for purpose, our oracle ensures the most accurate price data is provided to the platform and negates the risk of malicious attacks and arbitrage.

Basis of logic

$f(x) = x * e^{2 pi i \xi x}$
