Description

This PR introduces two new optional fields, BlockOverrides and StateOverrides, to the eth_call method. These fields are designed to enhance the functionality of eth_call and are particularly used by account abstraction bundlers to simulate user operations prior to submitting them to the blockchain.

Changes

BlockOverrides

• Modifies the context in which the transactions of a given block are executed.
• When overriding multiple blocks:
  • Block numbers must increment.
  • Skipping block numbers is allowed, and skipped blocks are included in the response.
  • Time across multiple blocks must be increasing. If time is not explicitly specified, it increments by one for each block.

StateOverrides

• Provides an optional address-to-state mapping.
• Each entry specifies some state to be ephemerally overridden before executing each block.

Notes

• No breaking changes; these fields are optional and do not interfere with existing behavior.
• The enhancements align with ongoing improvements to support account abstraction workflows.
• For more details, refer to the geth documentations.
