Founded in December 2024, Eureka Labs builds Ethereum blocks with added execution logic it calls "programmable blocks," enabling capabilities such as intra-block credit, state-aware pre-computation, execution-time external data access, and deterministic transaction placement. The company operates within Ethereum’s Proposer-Builder Separation architecture and aims to make blocks active execution environments rather than passive containers of transactions. Eureka’s business model collects fees from transactions included in the blocks it builds. By number of blocks built it has become the fourth-largest Ethereum block builder, though its market share is around 1.5% compared with the three largest builders. The team is about 12 people, is based in Tel Aviv, and recently opened an additional research and development site in Poland; the company is hiring for technical roles across both locations.
