Partner with ETH Bucharest 2025 - Eastern Europe’s Leading Ethereum Conference and Hackathon
Non-Constitutional
Abstract
The proposal invites Arbitrum DAO to sponsor ETH Bucharest 2025, showcasing its Layer 2 ecosystem and Stylus technology while supporting the Hackathon Open Track to drive real-world use cases and foster impactful startups.
The total investment for this proposal is set at $ 67,950 (10% discount included).
This partnership strengthens Arbitrum’s leadership in innovation and community engagement.
Motivation
ETH Bucharest 2025, taking place from April 2-5, will build upon the success of last year’s conference, which attracted 1,100+ unique attendees and 100+ hackers.
For 2025, we expect over 1,500 community enthusiasts and 150 hackers, with a diverse range of speakers, tracks, and events dedicated to fostering Ethereum and Web3 innovation in Eastern Europe.
Your continued involvement will be instrumental as we work to create a pivotal gathering for the Ethereum community in this region.
Arbitrum has already had a significant impact at ETH Bucharest 2024 (from 27th to the 30th of March 2024), with @ZER8 and @DisruptionJoe making Arbitrum’s presence felt on-site.
This was the first time Arbitrum DAO had a booth at a conference and
Our collaboration deepened as we hosted the first ever IRL Arbitrum Workshop and Hackathon, which focused on Stylus—a groundbreaking technology for fully EVM-compatible smart contracts written in Rust.
This initiative was funded by the Arbitrum Education, Community Growth and Events 2.0 with $ 22,524 and was completed in November 2024.
This workshop and hackathon set the stage for Arbitrum’s next evolution, creating unique momentum in Romania’s fast-growing Ethereum community.
