Classover Holdings, a Nasdaq-listed education technology company, has secured $500 million in funding through senior secured convertible notes to advance its Solana treasury strategy. The company plans to allocate up to 80% of the proceeds from this new funding round to purchase Solana (SOL) tokens. This follows a recent $400 million equity raise, bringing Classover's total available capital for building its Solana-based crypto treasury to approximately $900 million. Classover has already made an initial purchase of $1.05 million in SOL and intends to hold and stake these tokens long-term. Meanwhile, Solana's blockchain ecosystem showed robust growth in May 2025, with real economic value reaching $121 million (up 37% month-over-month), application revenue at $214 million (up 22% MoM), and decentralized exchange volumes hitting $135 billion (up 32% MoM). Although the stablecoin supply on Solana declined by 13.5% to $11.4 billion, the platform remains a leading choice for internet capital markets, supported by major players such as Kraken, Fidelity, and R3. Solana is also noted as the fastest-growing blockchain for stablecoin issuance, with outstanding stablecoin supply growing 120% month-over-month.
