eth_createAccessList

Creates an EIP-2930 access list that you can include in a transaction.

Use this method to optimize your smart contract interactions. Access lists are a part of Ethereum's EIP-2930, which aims to improve the network's scalability and reduce gas costs by specifying an explicit list of addresses and storage keys that a transaction intends to access.

Officially, we do not yet support eth_createAccessList

Parameters

• Transaction call object: [Required]

  • from: 20 bytes. The address of the sender.

  • to: 20 bytes. Address the transaction is directed to.

  • gas: Hexadecimal value of the gas provided for the transaction execution.

  • gasPrice: Hexadecimal value gas price (in wei) provided by the sender. The default is 0. Used only in non-EIP-1559 transactions.

  • maxPriorityFeePerGas: Maximum fee (in wei) the sender is willing to pay per gas above the base fee. See EIP-1559 transactions. If used, must specify maxFeePerGas.

  • maxFeePerGas: Maximum total fee (base fee + priority fee, in wei), the sender is willing to pay per gas. See EIP-1559 transactions. If used, must specify maxPriorityFeePerGas.

  • value: Hexadecimal of the value transferred, in wei.

  • data: Hash of the method signature and encoded parameters. See Ethereum contract ABI specification.

• block parameter: A string representing a block number, block hash, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.

Returns

Access list object with the following fields:

• accessList: A list of objects with the following fields:

  • address: Addresses to be accessed by the transaction.

  • storageKeys: Storage keys to be accessed by the transaction.

• gasUsed: A hexadecimal string representing the approximate gas cost for the transaction if the access list is included.
