gm, dear Ethereum fam 🧜🏻♀️
We're sure you've been waiting for this message. So, it's official now:
The fourth edition of the ETHWarsaw Conference and Hackathon will take place on September 4-7!
The conference and hackathon will occur at the ADN Conference Hall, located in the busy and vibrant district — Browary Warszawskie.
🧩 The thesis behind ETHWarsaw 2025
We're bullish about 2025, and we believe that we're all one step to the mass blockchain and crypto adoption. However, we have to build responsibly, develop product mindsets, and stick to the values of decentralization.
Remember, we’re here to build new patterns:
From paternalistic to ➡ independent;
From duties to ➡ initiatives;
From passive to ➡ active;
From trust to ➡ verification;
From side control to ➡ personal freedom.
We all have the power to change the status quo and build more reliable decentralized social systems.

How it was in 2024, and what you should expect this year 👀
We have established the Warsaw Blockchain Week to enable global web3 companies and local communities to organize their events under one big brand in the capital of Poland.
For the main conference and hackathon, we gathered in the heart of modern Warsaw to teach, learn, research, build, pitch, and have fun in the community of like-minded and blockchain-focused people.
Here is a short recap in numbers:
4 amazing days;
800+ attendees;
26 sponsors;
114 hackers;
$86 000 in bounties;
26 side events (including community gatherings, workshops, brunches, and loud parties);
hundreds of beautiful photos and lots of great feedback.

In the article on Medium, we described ETHWarsaw 2024 in detail. Read it to learn more about the topics, sponsors, and activities.
This year we plan to bring in even more builders and founders who shape the ecosystem. We want to show the REAL VALUE of decentralized products and a future where dApps are used by our friends and neighbors.
We’re interested in hosting speakers with fresh ideas and mentors with strong abilities to teach coding and tech concepts as well as growth, scalability, and promotion of blockchain-powered projects.
