Overview
In order to make permissionless loans work, an NFT price oracle is required to determine the NFT's value. Initially, the floor price of the collection will be used to set the underlying value for supplied NFTs. Premiums based on rarity traits will be added later on.
The NFT floor price oracle is built using Chainlink infrastructure, enabling anyone to become a node operator.
The floor price is calculated in 4 steps: 1. Verifying sale 2. Extreme outliers removal 3. Probable outliers removal 4. Floor and 24 hour TWAP
