Come September 4–7, 2025, Warsaw’s flagship Ethereum conference and hackathon — anchored at the ADN Conference Center in Browary Warszawskie — returned for its fourth edition with a builders-first focus. As the centerpiece of Warsaw Blockchain Week, ETHWarsaw has grown into Central Europe’s premier Web3 gathering, coupling deep technical content with a citywide slate of side events.
The agenda makes that promise tangible, orienting talks, workshops, and the hackathon around practical outcomes for developers, founders, and investors.
It’s often noted that Warsaw’s Web3 scene punches above its weight; ETHWarsaw is both a cause and effect of that phenomenon.
There are 368 active Web3 job listings in Poland at the time of writing, pointing to high demand for developers; and 52 cryptocurrency companies in Warsaw, per Tracxn, reflecting the capital’s rise as a cost-competitive, innovation-friendly hub.
In essence, Warsaw is now viewed as a rising blockchain hub, and ETHWarsaw is the beating heart of that hub. Today, ETHWarsaw is frequently mentioned in the same breath as ETHBerlin or even ETHDenver (the latter being a much older, larger event) as a key gathering for the Ethereum community — especially in Europe.
What ETHWarsaw Offers Attendees
ETHWarsaw’s value proposition can be broken down into a few key components: cutting-edge content tracks, a marathon hackathon, structured and organic networking, and a variety of side events that together create an immersive week-long experience.
Four Focused Conference Tracks
The conference program (Sept 4–5) is divided into four thematic tracks, each homing in on a crucial aspect of Ethereum and Web3 development today:
- Infrastructure Track:
This zeroes in on the backbone of Ethereum’s stack — Layer-2 scaling, zero-knowledge proofs, cross-chain tooling, and emerging AI/blockchain integrations. Expect workshops like “ZKPs in Production,” hands-on sessions exploring high-performance smart contracts, with speakers such as Andrii Bondar (Matter Labs/ZK Sync) and Piergiacomo Palmisani (Taiko) on the roster.
- Resilience Track:
This addresses security, privacy, and governance. A highlight is a session with Laurence Kirk on smart-contract robustness and the emerging intersection of agentic AI with resilient, public-goods-minded protocols.
- Financial Freedom Track:
Concentrates on DeFi, stablecoins, and real-world-asset tokenization. Mariia Yatsenko (Centrifuge) outlined how to turn idle TVL into active utility by bringing off-chain yield on-chain, while legal and policy voices map Europe’s evolving rulebook and its implications for on-chain finance, with the presence of speakers from projects like Ramp Network and Zetachain (both sponsors involved in crypto payments and multi-chain finance).
- Mass Adoption Track:
Focuses on UX, onboarding, and community growth. Panels such as “Web3 UX Strategies” — a panel likely featuring UX researchers who will share how to simplify wallets and dApps for everyday people, with speakers like Karolina (a Web3 marketer), Mac Budkowski (a veteran founder), and Daria Volkova (host of Decentralized Voices podcast).
The four tracks ensure that whether you’re a hardcore protocol developer, a DeFi economist, or a community manager, ETHWarsaw has tailored content. “The content was on par with global events, but with local relevance,” as one 2024 attendee noted. In 2025, that bar is set even higher.
The Hackathon: Where Builders Build
Three-day event for developers to build Ethereum solutions, with mentorship and prizes from sponsors like Base (Coinbase’s Layer-2 network) and RedStone (a Polish-founded oracle protocol). The hackathon kickoff (Friday evening) and closing “Bounty Demos” session (Sunday) are highlighted on the agenda – everyone is keen to see what cutting-edge dApps emerge by the end.
Networking: From Roundtables to Rooftops
Networking is engineered, not left to chance. Structured sessions — “Web3 Founders Roundtable,” “Investor Meet & Greet,” “Women in Web3 Lunch” — sit alongside informal evening gatherings, meetups, and yes, the occasional crypto-rave.
Warsaw Blockchain Week Side Events
Side events (Sept 3–10 roughly) deepen the week’s utility.
ETHLegal (Sept 4), held under the patronage of Poland’s Ministry of Finance, convenes counsel, policymakers, and founders to navigate compliance, taxation, and AML in a MiCA world.
Urbe Campus (Sept 5–8) runs hands-on builder workshops with the UrbeETH crew — part bootcamp, part strategy lab for hackathon-ready teams.
Zircuit’s Meetup (Sept 6) digs into AI-powered DeFi. SheFi Warsaw hosts its first local chapter gathering to push inclusivity from talk to practice.
SheFi Warsaw (Sept 7), a global educational initiative aimed at women in crypto features too.
Together, these events, amongst others, widen the funnel for newcomers while giving veterans meaningful deep dives.
Why It Matters: Execution Over Hype, Warsaw’s Web3 Role, and Real Outcomes
ETHWarsaw’s significance extends beyond the event itself; it’s a microcosm of where the Web3 industry is headed and a catalyst for the ecosystem’s next wave.
ETHWarsaw’s emphasis on developers, on shipping code, and on practical solutions (like RWA integration, or secure smart contracts) shows the community doubling down on building. ETHWarsaw’s co-founder Monika Zając captures it well, “This [event] is for people who write code, launch products, and scale solutions.” That ethos is crucial — it’s how the industry moves from speculative phase to maturity.
Secondly, the event cements Warsaw’s strategic role by convening global protocols with Polish talent. Central and Eastern Europe’s (CEE) developer density, competitive costs, and growing investor base make the city a natural hub; ETHWarsaw amplifies that advantage by convening global protocols with Polish talent.
Crucially, the outcomes are tangible. Developers leave with skills, mentors, and job offers; founders find partners and, maybe, funding; and ETHLegal helps shape compliance. Hackathon demos often evolve into grants, incubators, or pilot customers.
With sponsors from ecosystem mainstays to local champions, including AKASHA Foundation, Base, Binance, BingX, Ramp Network, RedStone, Zircuit, and others throwing their weight behind ETHWarsaw, Warsaw’s builders are seen as drivers of real-world impact. In an industry that rewards shipping, ETHWarsaw is a launchpad.
