Floor Protocol is a decentralized platform that enables NFT fractionalization and trading through Vaults and Safeboxes. Vaults allow users to deposit NFTs and receive μTokens representing fractional ownership, while Safeboxes let holders retain ownership and issue μTokens. The platform's native token, $FLC, serves as an index token reflecting major NFT collections. Features include a peer-to-peer marketplace (BT404), staking, auctions, and valuation tools.
