Feature your event

Ecosystem: Ethereum

Explore Ethereum events shaping the world’s largest programmable blockchain and the backbone of Web3. Ethereum pioneered smart contracts and remains the settlement layer for DeFi, NFTs, DAOs, stablecoins, and a growing universe of Layer-2 rollups and zero-knowledge applications. With the deepest developer community, robust tooling, and a decentralized validator set, the Ethereum ecosystem continues to drive innovation in scalability, restaking, account abstraction, and onchain coordination—making Ethereum conferences essential touchpoints for anyone building the open internet.

From global summits and technical hackathons to local meetups, research workshops, and developer gatherings, these events bring the Ethereum community together to ship ideas and push the stack forward. Founders use them to pressure-test concepts, recruit co-founders, close funding conversations, and connect with L2 teams, infra providers, and protocol leads. Builders walk away with working prototypes, new collaborators, and direct access to the people defining Ethereum’s roadmap.

Hosting something for the Ethereum community? Post your event on Web3Voyager to reach builders, founders, developers, investors, and users actively engaged across the ecosystem.
