Deterministic Placement for Searchers

Deterministic Block Placement lets searchers express explicit conditions for where transactions land in a block — after a specific contract call, when a storage slot changes, or at a precise index.

If conditions aren't met, the bundle is excluded entirely. This removes mempool racing and enables strategies that depend on exact ordering relative to other intra-block state transitions.

Combined with Builder Execution Extension, searchers can simulate thousands of paths off-chain and land the winning execution exactly where it needs to be.
