DeFi Development Corp. increased its Solana treasury by 55,491 SOL since Aug. 27 to 2,388,923 SOL and SOL equivalents as of Sept. 14. The Nasdaq-listed company also established an at-the-market program allowing it to sell up to $300 million of its Variable Rate Series C Perpetual Preferred Stock, known as CHAD. DeFi Development intends to sell CHAD at or above its $10 stated amount, with net proceeds expected primarily to purchase additional SOL. The facility does not represent capital already raised, as sales remain subject to the company's decisions and market conditions. The company holds and stakes SOL, operates validator infrastructure and has outlined plans to use part of its treasury in Solana-based DeFi applications.
