Eureka Labs raises $6.7M seed from Spark Capital to build programmable blocks for Ethereum's proposer-builder separation.
VC & Fundraising ·
Eureka Labs, an Ethereum block builder, has raised $6.7M in seed funding led by Spark Capital. The funding announcement coincides with the introduction of programmable blocks designed to enhance block construction logic within Ethereum's proposer-builder separation framework.
Programmable blocks enable customizable logic during the block-building process, extending capabilities beyond standard block construction. This development targets the infrastructure layer of Ethereum's PBS mechanism, which separates the roles of block proposal and block building to improve network resilience and validator economics.
The specifics of how Eureka Labs' programmable blocks will integrate with existing PBS workflows, the timeline for deployment, and the full list of participating investors beyond Spark Capital remain undisclosed in available reports.
