ProtonChains is an engineering company from Slovakia. We are not a body shop and we are not an agency — we design, build and commission systems, and we stay responsible for them afterwards.
Founded in 2018, we have delivered more than 15 projects for clients in Slovakia and across the EU.
Everyone here has enough years behind them to have seen a project go wrong, and enough breadth to cover for somebody else. That overlap is deliberate — it is what keeps a delivery date from depending on one person's calendar.
We work in architecture, high-performance backends, front-end and industrial control. The same people move between those worlds, which is why a control system we build has a decent API, and a backend we build understands what a plant is.
Reworked from what our clients actually tell us, rather than from a list of corporate values.
A senior team writes less code to solve the same problem. That is where the speed comes from — not from cutting the review.
Broad, overlapping competencies mean no single point of failure in the team. It measurably reduces risk for the client.
Scalable and secure solutions, built for throughput and predictable latency from the architecture stage rather than patched later.
Cloud or on-premise, leading-edge or boringly stable — we pick what fits your constraints, not our preferences.
Industry-specific security requirements, performance standards and regulation. Learning them up front is what makes delivery precise.
Documentation, handover and support are part of the job, not an upsell. The project ends when you can run it without us.
altFINS used Protochains for development of our smart contract, which was deployed on Avalanche network. Their process was very professional, timely and thorough. After a couple of consultations, Protochains team delivered an initial needs assessment and proposal for smart contract functions. Then we received a testnet implementation, which we reviewed together, and the final smart contract was delivered shortly after. The entire process took only two weeks. We also appreciated their responsiveness and communication. The team reviewed the final smart contract with us, provided a clear manual for how to use various functions, and also provided an audit document.
Na spoločnosť ProtonChains s.r.o. sme sa obrátili s požiadavkou na spoluprácu pri vývoji v technológii Angular a nástroji Elixír. S efektívnym porozumením sme sa dohodli na rozsahu a podmienkach spolupráce. Následná realizácia bola zo strany našich partnerov mimoriadne profesionálna. Nie len že úplne splnili vecné zadanie a dodržali časový harmonogram, ale aj forma a spôsob dodania boli na veľmi vysokej úrovni. Kvalitne zdokumentované SW dielo, s praktickou ukážkou pre jeho ďalšie použitie, zavŕšili túto, rozsahom síce malú ale kvalitou a prístupom veľmi úspešnú spoluprácu. Veríme, že firiem s takýmto kreditom bude v našom okolí stále viac a viac. Ďakujeme.
