Privacy public chain project Octra will conduct a public token sale on Sonar (founded by Echo and recently acquired by Coinbase) on December 18, 2025, aiming to raise $20 million by selling 10% of the total OCT supply, corresponding to a $200 million FDV. Unsold tokens will be burned. Early investors hold 18% of the tokens, the team holds 15%, and the remaining 67% is allocated to the community. Previously, Octra completed a $4 million pre-seed funding round with investors including Big Brain Holdings and others. (The Block)
