The team behind 23studio
23studio (23stud.io) is a Web3 and blockchain development studio from Warsaw, Poland. We build smart contracts, DeFi products, indexers and governance tools for founders and ecosystem foundations.
Short story
From hackathons to production protocols
We started by building our own projects and winning hackathons, which led to grants from the Aleph Zero Foundation and then to client work. Along the way we noticed founders kept asking for the same thing: a team that could take a blockchain idea and ship it properly.
That team became 23stud.io. Since then we have built for the Aleph Zero Foundation, HyperBloom on HyperEVM, DeSwarm on Berachain and our own ventures, from first prototypes to audited contracts in production.
The principles that define us
Our hackathon background powers fast, high-quality delivery. From working prototypes in weeks to full launches in months, we prove value quickly while maintaining excellence
Proven through critical infrastructure for Aleph Zero and complex platforms like Dark Side Suits, we build secure, scalable solutions that handle real-world demands
We transform complex blockchain interactions into intuitive experiences. Our products drive adoption by making Web3 accessible to everyone, from DeFi traders to governance participants
The people who make it all happen
We’re a diverse team of engineers, designers, strategists, and visionaries, all driven by a shared passion for technology and innovation.

How we work
Five steps from first call to a product in production. You see working builds at every milestone and talk directly to the engineers.
Get an estimateConsultation & Analysis
We learn what you are building, check the technical and business requirements, and recommend a scope and phase: PoC, MVP or full release.
Architecture & UX/UI Design
We pick the chain, design the contract architecture and data flow, and design the interface, including wallet and transaction states.
Development
We build the contracts, backend and frontend, connect them to your existing systems, and test functionality and security as we go.
Deployment
We deploy to mainnet after final security and performance checks, and an external audit where funds are at stake.
Post-Launch Support
We monitor the system, ship fixes and updates, and help you scale as usage grows.
