Use case

The eth_createAccessList method is crucial for:

• Preparing transactions that optimize gas usage by explicitly stating which addresses and storage keys will be accessed.
• Developers aiming to reduce transaction costs and improve efficiency on the Base network.
• Transactions that comply with EIP-2930, which introduces access lists as a transaction type to specify state access.
