ETHSofia 2026 is Bulgaria’s leading Ethereum and Web3 conference, taking place on September 24, 2026, at Sofia Tech Park in Sofia, Bulgaria.
The event is designed for builders, researchers, protocol teams, security professionals, service providers, institutions, and companies integrating Ethereum into production systems. Its 2026 theme, “Cypherpunk Technology for Institutional Capital,” reflects the growing connection between Ethereum infrastructure, privacy, decentralized finance, tokenization, and institutional blockchain adoption.
ETHSofia is also the flagship builder conference of Blockchain Week Bulgaria, which runs from September 23-25, 2026, at Sofia Tech Park.

How the Event Is Set Up
ETHSofia 2026 takes place at the John Atanasoff Forum inside Sofia Tech Park, Bulgaria’s first science and technology park. The venue is surrounded by startups, established technology companies, investment funds, research facilities, and advanced infrastructure including the Discoverer Petascale Supercomputer.
The conference is positioned as a boutique-style networking event, prioritizing direct conversations, technical discussion, and curated access to Ethereum builders rather than a broad mass-market expo.
