Tensor is a NFT marketplace on the Solana blockchain that transitioned into an AMM-integrated marketplace allowing users to provide liquidity for both buy and sell orders within specific NFT collections.

Tensor's main products and features include an AMM & Marketplace that integrates auctions and instant liquidity for NFT sales on Solana, with no execution fees and a 1% fee for takers. It provides collection-wide bids, listings with dynamic pricing, and market-making orders for liquidity provision. Additionally, Tensor acts as an aggregator with analysis tools. It also offers a Rarity Ranking mechanism to assess NFT prices based on rarity.
