Module conditional_tx 

eth_sendRawTransactionConditional — Arbitrum’s conditional tx submission RPC.

Lets a client attach predicates (block-number range, timestamp range, per-account storage roots / slot values) to a raw tx. The sequencer only accepts the tx if every predicate holds against current chain state. Used by MEV-aware clients to fail fast when a trade opportunity has already been consumed.
