First Block, Inc., a digital securities and tokenisation infrastructure company, together with Onpharma Company (Delaware) and UK-based Crito Capital LLP, today announce the launch of what is believed to be the first Solana-based Security Token Offering ("STO") for an established U.S. operating business, a structural turning point in the modernisation of global private markets. 

The Tokenisation Framework 

The STO deploys Solana blockchain infrastructure combining atomic settlement technology, programmable ownership architecture, and digital distribution capabilities, structured within existing U.S. securities law. Where traditional private markets have struggled with fragmented, multi-intermediary processes, the tokenised framework enables issuance, settlement, and cross-border distribution to qualified investors quickly, transparently, and at low cost. Secondary transactions occur on-chain across compatible wallets subject to KYC controls, delivering near-instantaneous settlement, secondary trading liquidity, and international accessibility under Regulation S and other applicable frameworks. 

The STO Structure 

A Security Token Offering represents and transfers ownership rights in a company's common stock via blockchain-based digital tokens rather than traditional share registers. The Onpharma STO is structured as a Regulation S offshore issuance to non-U.S. investors, combining the legal certainty of an exempt securities offering with the operational efficiency of Solana infrastructure, settling and distributing at speed and cost traditional private markets cannot match. 

Onpharma: The Investment Case 

Onpharma occupies a distinctive position in global dental technology. Its Onset EZ local anaesthetic buffering product is already used to buffer millions of dental injections annually, addressing the slow, uncomfortable, and unreliable performance of dental local anaesthetic that has remained largely unsolved for decades. The Onset EZ Pen requires no assembly or specialist training, integrating directly into existing workflows for an improved patient experience. 

Onpharma sits at a post-validation, pre-scale inflection point: infrastructure, supply chain, regulatory compliance, and initial commercialisation are complete, while the growth phase is beginning. Septodont's February 2025 market entry has validated anaesthetic buffering as an emerging standard of care, reducing category risk and increasing awareness. The disposable Onset EZ Pen provides operational leverage through scalable direct marketing, customer conversion, and repeat consumable revenue. The global dental anaesthesia buffering market is valued at $2bn and projected to reach $2.65bn by 2030. Capital raised will extend field sales and expand direct selling via the company's recently deployed AI marketing tools. 

The Infrastructure 

First Block's digital securities architecture underpins the transaction from issuance and compliance through to Solana-based settlement and distribution, compressing conventional private placement infrastructure, fragmented custodial arrangements, manual processing, multi-intermediary chains, into a single programmable, blockchain-enabled system built for the scale, speed, and wallet-level accessibility international investors increasingly require. Crito Capital LLP, an FCA-authorised investment banking and advisory platform focused on institutional capital formation, is providing structuring and advisory for the offering. 

"This is larger than a traditional financing," said Daniel P. Cannon, CEO of First Block. "We believe this transaction represents the beginning of the convergence between capital markets and Solana-based securities infrastructure. The STO itself is the story, but it starts with a real operating company, a real product, and exceptional revenue growth potential." 

"Onpharma has spent years building a real operating business around a simple clinical objective: making local anaesthetic better for dentists and patients," said Matt Stepovich, Onpharma’s CEO. "This offering allows us to present a validated, revenue-generating medical device platform to a wider base of qualified international investors via a structure that reflects how capital markets are evolving. Combining Onpharma's real-world commercial traction with First Block's Solana-based securities infrastructure is an important step in making growth capital formation more efficient, accessible and transparent."
