What’s next for Castar: tokenizing stocks

The next chapter for Castar is tokenizing stocks. To build it properly, we need to own more of the infrastructure beneath the product.

Neobanks made a better financial interface the expectation. A good app, a card and a smooth onboarding flow used to stand out. Today, those are the starting point. As more companies assemble similar products from the same providers, we believe the pressure on margins will only get stronger.

That changes what it takes to build a durable business. When your product depends on someone else’s core infrastructure, their pricing shapes your economics and their roadmap limits yours. You can improve the experience around the edges, but you have less room to change what the product actually does.

Building the part that makes us different

For Castar, the answer is to build our own core asset infrastructure. We want more control over how ownership is represented, how assets move and how their value becomes useful to the person holding them.

That does not mean rebuilding every service ourselves. Specialist partners will still matter. It means owning the technology and product decisions at the centre of Castar, so our ability to improve the product is not limited to configuring another provider’s API.

Why tokenized stocks

Stocks are a familiar way to own a piece of a business. Tokenization offers a different way to represent and move that ownership. Our ambition is to connect that familiar asset to infrastructure that is easier to integrate, verify and build on.

The token is only one part of the work. A credible product needs a clear relationship to the underlying asset, accurate records, reliable reconciliation and a way to handle the events that happen after issuance. Transfers, restrictions, dividends and other corporate actions all need deliberate design.

We are building towards that whole system. The goal is for ownership to remain understandable as it moves between a wallet, an application and the services around it. Availability, supported assets and the rights attached to each product will need to be defined clearly as we bring it to market.

A team built for this work

Our team has worked in core blockchain infrastructure and real-world assets from the beginning. This is the engineering work we know: the systems beneath an application, where correctness and interoperability matter as much as the interface.

Members of our team are authors of frameworks used by RWA.xyz, Ink, Base, Polygon, Arbitrum, Robinhood and others. That experience gives us a strong foundation for the next stage of Castar.

Building infrastructure also means staying responsible for it. We want the people designing the ownership model to work closely with those building the ledger, integrations, operations and user experience. The details need to agree all the way through.

What comes next

Our focus is the core of that system: asset records, ownership verification, integration interfaces and the operational processes that keep them consistent. We will share concrete product and availability updates as the work progresses.

The app remains the place people experience Castar. Our own infrastructure is how we intend to give that experience a lasting advantage.
