eth_createAccessList on Plasma
Simulates a transaction and returns the access list (addresses and storage keys it touches), which can lower gas costs on EIP-2930 transactions.
Pre-computing the access list discounts first-touch storage/address costs — worth it for gas-sensitive, storage-heavy txs. The response also returns a gasUsed figure you can cross-check against eth_estimateGas.
