Web3 & blockchain development studio
Building Web3 That Works
Smart contracts, DeFi protocols, wallets and dApps for Web3 founders. A working PoC in 2–6 weeks, an MVP in 6–12.
Trusted by blockchain teams and foundations
We’re 23stud.io, a Web3 studio from Warsaw. We started out winning hackathons, went on to build infrastructure for the Aleph Zero ecosystem, and write Rust and Solidity every day. The goal is the same as on day one. Ship blockchain products people actually use.
From proof of concept to full release
A PoC in 2–6 weeks, an MVP in 6–12, a full release in 12–24.
Hackathons taught us to ship a working demo under a hard deadline. We kept that pace on client work and added the testing, code review and audits that production code needs.
PoC
2–6 weeksA working demo that shows whether the idea is worth taking further. Real contracts and a basic interface, not slides.
- Smart contract architecture design
- Core functionality implementation
- Basic interface development
- Technical feasibility validation
- Security considerations overview
MVP
6–12 weeksThe core features, built for real users, so you get feedback before you build the rest.
- Complete smart contract development
- Production-ready interface
- Core features development
- Basic analytics integration
- Security audit preparation
Full release
12–24 weeksThe complete feature set, fully tested and security audited, with infrastructure set up to scale.
- Advanced feature implementation
- Full security audit process
- Performance optimization
- Complete testing coverage
- Infrastructure scaling setup
