(Nasdaq: DFDV), formerly Janover, has increased its Solana holdings by acquiring 82,404 SOL, valued at approximately $11.2 million, bringing its total to 400,091 SOL (about $58.5 million). The company recently acquired a Solana validator business for $3.5 million, paid in restricted DFDV stock and cash. The acquired validators have an average delegated stake of around 500,000 SOL. All newly acquired SOL is being staked to earn native yield and support the Solana network. DFDV shares closed at $72.74, up over 1,700% in the last month, and Solana is currently priced at about $146. SOL Strategies Inc. (CSE: HODL, OTCQB: CYFRF), led by CEO Leah Wald, has signed a memorandum of understanding with Superstate, a blockchain firm led by CEO Robert Leshner, to explore issuing SEC-registered public shares directly on the Solana blockchain via Superstate's Opening Bell platform. This initiative, still in the exploratory phase and subject to regulatory approval, could make SOL Strategies the first public issuer to pursue this regulated pathway. No shares have been tokenized yet, and no timeline has been set. Superstate's Opening Bell platform, expected to launch this summer, is designed to enable the issuance and trading of SEC-registered equities on blockchains, with SOL Strategies as the first potential listing. The platform aims to provide real-time settlement and interoperability with decentralized finance protocols for both retail and institutional investors. Other companies identified as Solana Treasury Reserve firms include Upexi (UPXI) and ClassOver Holdings (KIDZ), reflecting the adoption of Solana-focused treasury strategies among publicly traded companies.
