get_cached_l1_block_number

Get the cached L1 block number for a given L2 block.

get_current_l2_block

Get the current L2 block number.

set_cached_l1_block_number

Set the cached L1 block number for a given L2 block.

set_current_l2_block

Mark the current transaction as an aliased L1→L2 type.

store_arbsys_state

Store ArbSys state changes for post-execution application.
