what's Eureka Labs?

Eureka Labs is a next-generation Ethereum block builder designed to redefine block construction within the Proposer-Builder Separation architecture. It introduces programmable blocks that embed advanced logic, enabling intra-block credit like uncollateralized loans lasting a single block, builder execution extensions for off-chain heavy computation with on-chain settlement, builder execution oracles for real-time external data synchronized to block inclusion, and deterministic transaction placement guarantees. These primitives expand on-chain possibilities by supporting capital-efficient trading, sophisticated MEV strategies, transaction privacy, and applications needing precise ordering or complex execution that previously exceeded block limits. Developers can leverage standard endpoints like eth_sendBundle while accessing Eureka's enhanced features via rpc.eurekabuilder.xyz.
