description: >-
  Fei Protocol was an Ethereum-based decentralized finance (DeFi) protocol that
  launched in April 2021, introducing FEI, an algorithmic stablecoin backed by
  Protocol Controlled Value (PCV), alongside the TRIBE governance token. Founded
  by Joey Santoro, it merged with Rari Capital in December 2021 to form the Tribe
  DAO. Following the April 2022 Rari Fuse exploit, the Tribe DAO voted to wind
  down and dissolve the protocol later that year. Fei Protocol was backed by a16z
  (Andreessen Horowitz), Framework Ventures, and other investors. Its smart-contract
  code and documentation remain public on GitHub, but the protocol is no longer
  operational and its web properties (fei.money, docs.fei.money) are offline. Fei
  Protocol is an on-chain smart-contract system and exposes no public REST/HTTP
  API, so it carries no OpenAPI, SDK, or hosted API artifacts.
