EthCC 9 (Ethereum Community Conference) 2026

Europe's largest annual Ethereum conference, organized by the non-profit Ethereum France team and rotating between Paris and Brussels. The 9th edition draws 6,000+ developers, protocol researchers, DeFi founders, and L2 engineers for four days of deep-technical talks, core-dev working groups, and a packed satellite-event calendar of side meetups and hackathons. EthCC is the default summer checkpoint for the European crypto ecosystem — if you're building on Ethereum, this is where the conversations happen. Tickets EUR 600-1,500.
