Data Sources

All NFT price data is sourced from multiple NFT marketplace by directly monitoring their floor price APIs. When the off-chain floor price data moves more than deviation threshold, an on-chain transaction will be triggered to write a new price into our oracle smart contract.

We have integrated the following NFT marketplaces into our data sources:

Marketplace	Retrieval Period	Trigger Deviation Threshold
Opensea	5 min.	2%
LooksRare	5 min.	2%
X2Y2	5 min.	2%

For CryptoPunks, we directly track the floor price from CryptoPunksMarket contract.
