StateChangePreBlockSource

reth_evm::block

Enum StateChangePreBlockSource 

pub enum StateChangePreBlockSource {
    BlockHashesContract,
    BeaconRootContract,
    WithdrawalRequestsContract,
    Other(&'static str),
}
Expand description

Source of a pre-block state change caused by an EVM system call that executes before transaction processing begins.

These system calls are protocol-level EVM invocations that update specific system contracts at the start of each block, prior to any user transactions.

Variants§

§

BlockHashesContract

EIP-2935: stores parent block hashes in a system contract for in-EVM access.

§

BeaconRootContract

EIP-4788: stores the parent beacon block root in a system contract, making consensus layer data available to smart contracts.

§

WithdrawalRequestsContract

EIP-7002: triggers the withdrawal requests contract to process any queued validator withdrawal requests.

§

Other(&'static str)

A custom pre-block state change not covered by the standard variants.
