DeFi Development Corp., listed on Nasdaq under DFDV, said it added about 47,706 SOL after Sept. 21, bringing total holdings to 2,538,010 SOL valued at about $309 million. The position increased about 2% over the past week and by more than 226,000 SOL, or roughly 10%, since the company released its second-quarter earnings on Aug. 12. DFDV stakes its SOL and operates its own validator to generate additional SOL and fee income. The company is also pursuing a planned $300 million CHAD perpetual preferred stock program that offers a 13% annual dividend and is intended to support further SOL purchases. Earlier treasury updates cited different purchase and holdings figures, so those discrepancies remain noted.
