Company profile
researched Aug 2026ETH Belgrade is an Ethereum-focused event held in Belgrade, Serbia, combining a conference with a hackathon and positioning itself as part of Belgrade Blockchain Week. The 2026 edition is scheduled for 26-27 August 2026 at the Sava Congress Center, a large congress venue originally built in 1976 and later renovated into an innovation, business and congress center. The conference runs two parallel stages (Amfiteatar and MR 9) with talks covering Ethereum protocol topics (state expiry, Glamsterdam, post-quantum signatures, Solidity), DeFi and stablecoin yield, layer-2 interoperability, real-world asset tokenization, security and supply-chain risk, and regulation.
The programme draws speakers from across the Ethereum ecosystem, including contributors and staff associated with geth, Argot Collective, Lido, CoW Protocol, Yearn, L2BEAT, Ambire, Block Analitica, Consensys, Fireblocks, Curvy, Wirex, Frankencoin Association, node101 and the University of Belgrade, alongside independent researchers and legal practitioners. Beyond the main conference, the organizers run a hackathon (ETH Belgrade Hackathon 3 was hosted on the TAIKAI hackathon platform, with tracks and bounty categories such as an ETHBelgrade $5,000 category and sponsor tracks like Xsolla ZK), plus coworking days, bootcamps and meetups, and an ETH Belgrade Ventures track offering founders pitch sessions and free booths.
The event is framed around the Belgrade and wider Balkan Web3 scene, which the organizers describe as home to more than 50 Web3 companies including DeFi Saver, Tenderly and Solflare.
Founding story
The idea for ETH Belgrade emerged from informal conversations among Balkan builders met at other Web3 events; co-founder Petar Popovic traces the concept to attending LisCon in 2021 and wanting to bring a similar atmosphere to Belgrade. Petar Popovic and Tanja Mladenovic co-founded the event and assembled a team around a stated mission of creating an Ethereum event grounded in builder needs and community values, holding the first edition by June 2023. Belgrade was chosen because of the concentration of regional Web3 companies and startups, including Tenderly and DeFi Saver.
Business model
ETH Belgrade operates as an event organizer, monetizing through sponsorships and ticket sales for its conference and hackathon; the website solicits sponsors and sells tickets, and sponsor-funded prize categories support hackathon tracks.
Sponsorship packages and attendee ticket sales for the conference; hackathon bounty categories are funded by sponsors.
Traction
The event has run multiple editions since June 2023, including a third hackathon hosted on the TAIKAI platform with sponsor-funded prize categories, and a 2026 conference programme featuring roughly 40 listed speakers across two stages. The organizers also run year-round coworking days, bootcamps and meetups and have advised other Ethereum event teams.
Latest developments
The 2026 edition is scheduled for 26-27 August 2026 at the Sava Congress Center in Belgrade, with a published two-day, two-stage agenda, an open call for speakers and sponsors, and ticket sales live.

Market position
ETH Belgrade positions itself as the premier Ethereum event in the Balkans and part of Belgrade Blockchain Week, drawing on Belgrade's local Web3 industry base of more than 50 companies. It sits alongside other regional and international Ethereum community events, with the organizers also advising other ETH event teams and sponsoring ETH Safari and ETH Rwanda.
The organizers emphasize hospitality and community hosting as a deliberate differentiator ("the most welcoming ETH event"), a merit-based speaker selection process in which slots are not for sale, agenda content that extends beyond protocol engineering into product design, regulation and go-to-market topics, and a ventures track providing founders with pitch sessions and free booths.
Technology
ETH Belgrade is an event rather than a software product; its hackathon is run on the third-party TAIKAI hackathon platform, where participating teams build Ethereum and layer-2 based projects.
Go-to-market
The event is promoted through its own website, X and LinkedIn channels and through the Ethereum community, with open speaker applications reviewed by a selection team (led by Nikola Vukovic of DeFi Saver and Natasa Bujosevic) and a stated policy that speaking slots cannot be purchased. Side events are open for anyone to host, and the organizers seed community hubs and meetups internationally, including "Road to Devcon" events in Africa and Southeast Asia, and sponsor other regional Ethereum events.
Ethereum and Web3 developers, hackathon participants, startup founders, blockchain enthusiasts and community members, and sponsoring companies and protocols in the Ethereum ecosystem, with a particular focus on builders from Serbia and the wider Balkans as well as international attendees.
Geography
Headquartered and held in Belgrade, Serbia, at the Sava Congress Center, with community activity extending across the Balkans and internationally through meetups in Africa and Southeast Asia and sponsorship of events such as ETH Safari and ETH Rwanda.
History
ETH Belgrade was conceived after LisCon 2021 and first realized in June 2023 by co-founders Petar Popovic and Tanja Mladenovic. It has since expanded beyond a single conference into a recurring programme that includes hackathons (the third edition ran on the TAIKAI platform), coworking days, bootcamps and meetups. The team has advised other Ethereum event organizers, sponsored ETH Safari and ETH Rwanda, flown in hackers from ETH Global Prague, and launched "Road to Devcon" meetups in Africa and Southeast Asia. The 2026 edition is scheduled for 26-27 August 2026 at the Sava Congress Center in Belgrade.
Risks & controversies
The organizers cite regulatory complexity as an ongoing consideration: EU MiCA rules can restrict non-EU projects from actively promoting services to EU customers absent reverse solicitation, while Serbia currently allows more flexibility. Hackathons also raise intellectual property and liability questions that the organizers address through participant and sponsor terms. As an event business, revenue depends on sponsorship and attendance and on venue and supplier contracts.
