# NFT Price Feeds Price feeds for the collateralized NFTs are determined by the floor price of NFT collection across multiple NFT marketplaces. In the case of NFTs from Ethereum chain, price feed from NFT Aggregator, collecting floor prices from dominant NFT marketplaces from Astar and Ethereum chains, including TofuNFT and OpenSea. The collateral value is denominated in Ethereum on Starfish for the NFTs that are on Ethereum chain. In the future, Starfish DAO will allow the SEAN stakers to manage the NFT class criteria in deciding the floor price algorithm. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
