description: Tensor is the Solana-native NFT marketplace and trading protocol founded by Tensor HQ and now stewarded
  by the Tensor Foundation. The platform exposes a public read REST API, a transaction-construction (TX) API that
  returns unsigned Solana transactions for list / buy / bid / pool flows, and a WebSocket subscription stream for
  realtime marketplace events. Five open-source Anchor programs — Marketplace, AMM v2, Whitelist, Escrow, and Fees
  — back the protocol and ship as `@tensor-foundation/*` JavaScript SDKs and `tensor-*` Rust crates. Tensor
  supports legacy NFTs, programmable NFTs (pNFT), and Bubblegum compressed NFTs (cNFT), and serves as the
  execution layer behind aggregators, wallets, sales bots, and AMM bonding-curve liquidity providers across the
  Solana ecosystem. Governance and ecosystem grants flow through the TNSR token and the Tensor DAO on Realms.
