The Rollup configuration.

Fields

genesis: ChainGenesis

The genesis state of the rollup.

block_time: u64

The block time of the L2, in seconds.

max_sequencer_drift: u64

Sequencer batches may not be more than MaxSequencerDrift seconds after the L1 timestamp of the sequencing window end.

Note: When L1 has many 1 second consecutive blocks, and L2 grows at fixed 2 seconds, the L2 time may still grow beyond this difference.

Note: After the Fjord hardfork, this value becomes a constant of 1800.

seq_window_size: u64

The sequencer window size.

channel_timeout: u64

Number of L1 blocks between when a channel can be opened and when it can be closed.

granite_channel_timeout: u64

The channel timeout after the Granite hardfork.

l1_chain_id: u64

The L1 chain ID

l2_chain_id: u64

The L2 chain ID

base_fee_params: BaseFeeParams

Base Fee Params

canyon_base_fee_params: BaseFeeParams

Base fee params post-canyon hardfork

regolith_time: Option<u64>

regolith_time sets the activation time of the Regolith network-upgrade: a pre-mainnet Bedrock change that addresses findings of the Sherlock contest related to deposit attributes. “Regolith” is the loose deposited rock that sits on top of Bedrock. Active if regolith_time != None && L2 block timestamp >= Some(regolith_time), inactive otherwise.

canyon_time: Option<u64>

canyon_time sets the activation time of the Canyon network upgrade. Active if canyon_time != None && L2 block timestamp >= Some(canyon_time), inactive otherwise.

delta_time: Option<u64>

delta_time sets the activation time of the Delta network upgrade. Active if delta_time != None && L2 block timestamp >= Some(delta_time), inactive otherwise.

ecotone_time: Option<u64>

ecotone_time sets the activation time of the Ecotone network upgrade. Active if ecotone_time != None && L2 block timestamp >= Some(ecotone_time), inactive otherwise.

fjord_time: Option<u64>

fjord_time sets the activation time of the Fjord network upgrade. Active if fjord_time != None && L2 block timestamp >= Some(fjord_time), inactive otherwise.

granite_time: Option<u64>

granite_time sets the activation time for the Granite network upgrade. Active if granite_time != None && L2 block timestamp >= Some(granite_time), inactive otherwise.

holocene_time: Option<u64>

holocene_time sets the activation time for the Holocene network upgrade. Active if holocene_time != None && L2 block timestamp >= Some(holocene_time), inactive otherwise.

batch_inbox_address: Address

batch_inbox_address is the L1 address that batches are sent to.

deposit_contract_address: Address

deposit_contract_address is the L1 address that deposits are sent to.

l1_system_config_address: Address

l1_system_config_address is the L1 address that the system config is stored at.

protocol_versions_address: Address

protocol_versions_address is the L1 address that the protocol versions are stored at.

superchain_config_address: Option<Address>

The superchain config address.

blobs_enabled_l1_timestamp: Option<u64>

blobs_enabled_l1_timestamp is the timestamp to start reading blobs as a batch data source. Optional.

da_challenge_address: Option<Address>

da_challenge_address is the L1 address that the data availability challenge contract is stored at.

Trait Implementations

impl Clone for RollupConfig

fn clone(&self) -> RollupConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RollupConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result
