genesis event in history at the time, raising approximately $1.3 billion in ETH, but whose novel 'direct incentive' peg mechanism immediately failed and trapped early participants with severe withdrawal penalties. After merging with Rari Capital to form Tribe DAO in December 2021, the combined protocol suffered an $80 million reentrancy exploit in April 2022 that precipitated a contentious governance crisis and the eventual dissolution of the DAO. Fei Labs and Rari Capital separately faced legal and regulatory consequences, including a class action securities settlement of $17.85 million and SEC charges against Rari Capital and its founders.","timeline":[{"date":"2021-03-08","event":"Fei Labs announces $19 million seed round led by Andreessen Horowitz, with participation from Framework Ventures, Coinbase Ventures, and Naval Ravikant.","source":"CoinDesk","source_url":"https://www.coindesk.com/business/2021/03/08/coinbase-naval-framework-ventures-back-19m-raise-for-a-capital-efficient-stablecoin"},{"date":"2021-03-31","event":"Fei Protocol Token Genesis Event opens.
