Flash Minibuilder May 2026
A is not a full block builder. Instead, it is a specialized, high-velocity engine designed to construct "miniblocks" or partial block bundles with extreme efficiency. These miniblocks are usually composed of time-sensitive transactions—often MEV strategies like arbitrage or liquidations—that must be executed within a single slot or even a sub-slot timeframe.
Establish direct TCP connections to validators' engine_api endpoints. Submit your miniblock as a engine_forkchoiceUpdated call with a payload attribute. flash minibuilder
Using evm or revm , simulate each bundle against the current block's pending state. Reject bundles that revert or exceed gas limits. A is not a full block builder
