ETHWarsaw is Eastern Europe's premier community-organized Ethereum conference and hackathon, forming the centerpiece of Warsaw Blockchain Week. Poland has earned a global reputation as a premier software engineering powerhouse, and ETHWarsaw channels that dense technical capability into protocol engineering, zero-knowledge scalability, and decentralized finance.
Poland's engineering excellence
Poland consistently ranks among the top countries globally for competitive programming and mathematical talent. Many core developers and protocol engineers at major L1s, L2s, and DeFi protocols are based in Warsaw, Krakow, and Wroclaw.
ETHWarsaw is deliberately builder-first: code audits, cryptographic primitives, and smart contract architecture take precedence over promotional marketing talks.
The Warsaw hackathon and builder culture
A major highlight is the 48-hour competitive hackathon, where hundreds of developers form teams to deploy innovative dApps across privacy, payments, and decentralized infrastructure. Protocol mentors and VC partners review submissions in real time.
Warsaw's central European location, affordable accommodations, and vibrant tech scene make it exceptionally accessible for international attendees.
