The ETH Bratislava Hackathon Vol.2 has solidified its position as a cornerstone event in the European Ethereum ecosystem, bringing together 54 passionate developers and showcasing 11 rigorously evaluated projects. Hosted at the Slovak University of Technology, this developer-centric gathering not only offered free access to the broader ETHBratislava conference but also created a fertile ground for innovation in blockchain scalability, interoperability, and real-world tokenization.
With a prize pool of 4,000 EUR, the hackathon fostered a dynamic environment where competition and collaboration coexisted, driving forward novel solutions that could shape the future of Ethereum. Participants benefited from mentorship by industry veterans, networking opportunities with leading figures in web3, and direct engagement with potential employers scouting for top-tier technical talent. The event concluded with a vibrant closing party—blending celebration with community-building—highlighting the social fabric that underpins technological progress.
This edition placed strong emphasis on three core innovation tracks: World Computer, Real-World Tokenization using EURØP, and Zircuit Restaking with AI-driven zkEVMs. Each track targeted pressing challenges within the Ethereum landscape, encouraging builders to push boundaries in decentralized applications, sustainable finance, and next-generation rollup architectures.

World Computer Track: Building Consumer-Facing dApps on Ethereum
The World Computer track focused on creating accessible, user-centric decentralized applications (dApps) that leverage Ethereum’s full potential. Projects in this category aimed to improve financial inclusion, enhance educational tools, and streamline interaction with smart contracts—core pillars of a truly open internet.
Two standout projects emerged from this category:
- Zhar: A decentralized platform that combines artificial intelligence with Ethereum’s blockchain infrastructure to manage and incentivize on-chain challenges. By using AI to validate tasks and distribute rewards via tokens and smart contracts, Zhar introduces a new model for gamified contribution and community engagement in web3 ecosystems.
- Ledger Lens: A powerful web application designed to visualize and analyze Ethereum’s multi-layer ecosystem. It provides real-time insights into key metrics such as token flows, cross-chain bridge activity, and wallet behavior—empowering both developers and analysts with transparent, actionable data.
These innovations reflect a growing trend toward making blockchain more intuitive and impactful for everyday users, aligning perfectly with Ethereum’s vision of becoming a global, decentralized computing platform.
Real-World Tokenization with EURØP: Bridging Finance and Blockchain
One of the most forward-thinking tracks was the European Stablecoin EURØP Challenge, which invited developers to build practical utilities around EURØP, a euro-backed digital currency designed to comply with emerging European regulations. This initiative supports the region’s push toward sovereign digital assets while enabling seamless integration into decentralized finance (DeFi).
Notable winners in this category include:
- dEST: A decentralized platform leveraging NFTs and smart contracts to enable peer-to-peer tokenized real estate transactions—removing intermediaries like brokers and title companies. With dEST, property ownership can be fractionalized, traded transparently, and settled instantly on-chain, opening doors to broader investment access and liquidity in traditionally illiquid markets.
- EnergyHub: An innovative application that allows individuals and organizations to monetize surplus green energy through blockchain-based trading. Using smart contracts and an intuitive dashboard, EnergyHub enables users to sell excess solar or wind power directly to the grid or donate it to communities in need—proving that blockchain can drive sustainability and social impact.
These projects demonstrate how stablecoins like EURØP can serve as foundational layers for regulatory-compliant, real-world asset tokenization across energy, real estate, and beyond.

Restaking Innovation on Zircuit: AI-Powered Security & Scalability
The Zircuit Restaking Track attracted some of the most technically advanced teams, focusing on enhancing security and scalability through AI-driven zk rollups. This track underscored the growing synergy between zero-knowledge technologies and decentralized consensus mechanisms, particularly in restaking frameworks that amplify capital efficiency and network trust.
Winner highlight:
- RestakerX: A sophisticated dashboard tool built for monitoring digital assets across the Zircuit network. It offers algorithmic yield optimization strategies, helping users maximize returns while maintaining security across restaked positions. By integrating AI analytics, RestakerX provides predictive insights into risk exposure and reward potential—crucial features for institutional-grade participation in restaking protocols.
This category signals a pivotal shift in how Ethereum scaling solutions are evolving—not just through better cryptography, but through intelligent systems that adapt to user behavior and market conditions.
