About

The EthClient Summit was a technical forum where Ethereum client developers and their users met face-to-face. It was a space for engineering excellence, sharing roadmaps, and surfacing real-world challenges.

This event brought together teams actively building or operating on Ethereum clients for a day of collaboration and knowledge sharing.

CLIENT TEAMS

Shared roadmaps and highlighted tradeoffs. Got direct feedback from people running their software in production. Aligned on upcoming features together.

INFRASTRUCTURE TEAMS

Engaged directly with client developers. Surfaced operational challenges like RPC performance, tracing quirks, indexing, and reorg handling. Helped shape solutions upstream.

ECOSYSTEM BUILDERS

Rollup, staking, and explorer teams who run or fork clients daily shared how client decisions ripple into their stack. Collaborated on making the foundation more robust.

// Together we aligned on features, solved problems, and strengthened Ethereum's foundations.
