What Was ETHLisbon 2023?
ETHLisbon 2023 was an Ethereum developer conference held in Lisbon, Portugal, from 3 to 5 November 2023. It brought together builders, hackers, and researchers from the global Ethereum community for talks, workshops, and networking in one of Europe's most welcoming tech cities. The official page sat on the ETHLisbon site. It is a community-run, builder-first Ethereum event.
Lisbon has become a favourite city for Ethereum events, drawing a serious developer crowd year after year. To follow similar events, check the crypto events calendar and our Web3 tech events list.
Key Themes at ETHLisbon
The agenda matched an Ethereum developer crowd:
- Ethereum protocol and Layer 2 scaling.
- DeFi, identity, and public goods.
- ZK-proofs and cryptography.
- Builder culture and open-source development.
Its community ethos set it apart from commercial shows. Many guests also tracked broader blockchain events through CoinGabbar.
How Crypto Is Growing in Portugal
Portugal has built a reputation as one of Europe's most crypto-friendly destinations, attracting developers, founders, and digital nomads from around the world. Its draw was sharpened for years by a favourable tax treatment for non-habitual residents and, crucially, a long period in which private crypto gains were untaxed for individuals. That changed when a 28% capital-gains tax on crypto gains held under one year came into force in 2023, bringing Portugal into line with wider EU norms while still leaving longer-held assets untaxed.
Lisbon hosts a thriving startup and tech community with deep Ethereum ties, and the city has become a recurring stop for major crypto conferences. As an EU member, Portugal now operates under MiCA, with the CMVM as the competent authority. The mix of lifestyle appeal, English-speaking talent, and a well-established expat crypto community makes Lisbon a natural home for builder-first Ethereum events.
