TechFlow News, March 25: According to The Block, Ethereum block builder Eureka Labs has closed a $6.7 million seed funding round, co-led by Spark Capital and Collider Ventures, with participation from Varrock Ventures, Node Capital, Reverie, Very Early Ventures, and angel investors. The financing was structured as a SAFE agreement with token purchase warrants.
The funding round was completed in two tranches: $4.7 million in April 2025 and an additional $2 million from Spark Capital in June of the same year. Avishay Ovadia, Founding Partner of Collider Ventures, has joined Eureka Labs’ Board of Directors. The company was founded in December 2024 and is publicly announcing both its launch and this funding information simultaneously.
Eureka Labs is launching “Programmable Blocks,” transforming blocks from passive transaction containers into active execution environments. This innovation enables features such as uncollateralized intra-block lending (intra-block credit), pre-computation based on precise state (reducing gas costs), real-time off-chain data ingestion, and deterministic transaction ordering.
