What Was DappCon 2023?
DappCon 2023 was an Ethereum dapp developer conference held in Berlin, Germany, from 11 to 13 September 2023. Dedicated to open-source Ethereum development, it brought together dapp builders, protocol researchers, smart-contract engineers, and the wider open-source Web3 community for deep technical sessions and workshops. The official page sat on the DappCon site. Its open-source ethos and developer focus set it apart from commercial expos.
DappCon is one of Europe's leading technical Ethereum events, rooted in Berlin's outsized role in the open-source blockchain world. To follow similar events, check the crypto events calendar and our Web3 tech events list.
Key Themes at DappCon
Sessions dug deep into Ethereum's open-source stack:
- Dapp architecture and smart contracts.
- Open-source tooling and standards.
- Security and auditing.
- Scaling and Layer 2.
The open-source, no-hype tone defined its character. Many attendees also tracked broader blockchain events through CoinGabbar.
How Crypto Is Growing in Germany
Germany is one of Europe's most important crypto markets, and Berlin is its open-source blockchain heartland. As the EU's largest economy, Germany has taken a central role in shaping the MiCA framework and has its own regulator, BaFin, enforcing some of the continent's more detailed crypto rules. Crypto is legal but not legal tender, with gains taxable under capital-gains rules.
For an open-source developer event, Germany's particular value is its technical community. Berlin has been home to Ethereum developers, DAI's creator MakerDAO, and dozens of blockchain startups since the early days of the protocol. Gnosis, one of Ethereum's most important infrastructure projects, has long been based here. The city's deep engineering culture, affordable rents compared with other European tech hubs, and openness to builder communities made it a natural home for Ethereum's open-source conference. Frankfurt's role as the European Central Bank seat adds a regulatory dimension, while Berlin remains the creative and technical engine. For more shows, see CoinGabbar's crypto conferences page.
Impact of the Event on Ethereum Development
A developer-focused conference in Berlin advances open-source Ethereum in concrete ways. It surfaces new dapp patterns and security research. It connects the global open-source community. And it deepens tooling and standards. Each edition moves the open-source ecosystem forward.
Why Sponsors, Exhibitors and Projects Should Join
A developer-first conference reaches builders, not buyers. Strong fits include:
- Tooling and infra projects: onboard open-source developers.
- Security and auditing firms: reach smart-contract builders.
- Layer 2 and scaling projects: recruit contributors.
- Foundations and grants: fund open-source work.
- Protocol researchers: meet implementation teams.

Why KOLs, Media and Influencers Attend
Open-source Ethereum work makes the news that matters to developers. Creators meet the engineers defining dapp architecture. Coverage can spread through the crypto press release network.
Why Builders and Participants Join
For Ethereum engineers, DappCon is a homecoming. You go deep on smart-contract patterns, security, and tooling alongside the open-source builders who wrote the code you use. Many leave with new techniques, security insights, and contributors to their projects.
