Odaily Planet Daily reports that Ethereum block builder Eureka Labs has announced the completion of a $6.7 million seed round led by Spark Capital and Collider Ventures.
The company has introduced the concept of "programmable blocks," incorporating executable logic during the block construction phase, enabling blocks not only to bundle transactions but also to perform more complex functions such as temporary fund access, advanced computations, and finer-grained transaction ordering.
Eureka Labs, founded in December 2024, has become the fourth-largest block builder on Ethereum, though it holds only about 1.5% market share, still significantly behind the leading builders. This funding round was completed in two phases: $4.7 million raised in April 2025 and an additional $2 million in June. The company stated that the proceeds will be used to expand its block building capabilities and advance the adoption of "programmable blocks" within the Ethereum ecosystem.
