ETH Barcelona 2026

about this room

The largest Ethereum festival in Europe returns to Barcelona for five days of conference talks, hackathon builds, music and crypto culture. 2,500+ attendees and 100+ speakers across the main conference (Jul 5–7) and a hackathon (Jul 7–9). A major anchor event for the Web3 ecosystem in Southern Europe — if you work in blockchain, DeFi, tokenisation, or decentralised infrastructure, this is the week to be in the city. Satellite events and builder houses pop up across 22@ and the waterfront throughout the week.
