Configuration for the EVM.

type Spec: Into<SpecId> + Clone

Required Methods

fn chain_id(&self) -> u64

Returns the chain ID of the EVM that is compared with the transaction’s chain ID.

fn tx_chain_id_check(&self) -> bool

Returns whether the transaction’s chain ID check is enabled.

fn spec(&self) -> Self::Spec

fn blob_max_count(&self) -> Option<u64>

Returns the blob target and max count for the given spec id. If it is None, check for max count will be skipped.
