Transaction Level Hinting Considered Helpful
summary
Proposes a concrete new transaction type that embeds transaction envelopes with two predicates: restrict execution to specified Merkle leaves and run only if those leaves have given values, plus optional access lists and a block access list so builders can prefetch state and avoid executing every tx to detect contention. Frames this as EIPs extending Flashbots-style block builders, offloading some verification to users for lower builder fees and enabling statelessness; no production implementation yet, calls for an EIP and client work and notes work-in-progress tools to extract state.
