Required Methods

fn destination(&self) -> Address

Call destination

fn blob_versioned_hashes(&self) -> &[B256]

Returns vector of fixed size hash(32 bytes)

fn max_fee_per_blob_gas(&self) -> u128

Max fee per data gas

Provided Methods

fn total_blob_gas(&self) -> u64

Total gas for all blobs. Max number of blocks is already checked so we dont need to check for overflow.

fn calc_max_data_fee(&self) -> U256

Calculates the maximum [EIP-4844] data_fee of the transaction.

This is used for ensuring that the user has at least enough funds to pay the max_fee_per_blob_gas * total_blob_gas, on top of regular gas costs.
