Frontier doesn't support eth_createAccessList json RPC method

[Niraj-Kamdar]

Motivation

The lack of support for the eth_createAccessList JSON RPC method in Frontier is causing a significant limitation in our ability to fully leverage Ethereum's transaction access list feature. This method is crucial for improving gas estimation and transaction efficiency, which are essential for optimizing the performance of our applications. Without this functionality, we are unable to test and implement access list transactions effectively, leading to potential inefficiencies and increased costs.

Suggested Solution

Implement support for the eth_createAccessList JSON RPC method in Frontier. This would involve ensuring that Frontier can handle requests for creating access lists as specified in the Ethereum JSON RPC API. The implementation should include full support for all parameters and expected outputs of the eth_createAccessList method, ensuring compatibility with existing Ethereum nodes and clients.

Additional Information

The eth_createAccessList method is part of the Ethereum Berlin hard fork and is essential for creating access lists that specify which storage slots and addresses a transaction will access. This feature helps in optimizing gas usage by pre-defining access patterns, thus reducing the gas cost for certain operations. Adding support for this method will align Frontier with the latest Ethereum improvements and enhance its utility for developers.
