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

hardforks: HardForkConfig

Hardfork timestamps.

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.

interop_message_expiry_window: u64

interop_message_expiry_window is the maximum time (in seconds) that an initiating message can be referenced on a remote chain before it expires.

alt_da_config: Option<AltDAConfig>

alt_da_config is the chain-specific DA config for the rollup.

chain_op_config: BaseFeeConfig

chain_op_config is the chain-specific EIP1559 config for the rollup.

Trait Implementations

impl Clone for RollupConfig

fn clone(&self) -> RollupConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RollupConfig

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

Formats the value using the given formatter.

impl Default for RollupConfig

fn default() -> RollupConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RollupConfig

fn deserialize<__D>( __deserializer: __D, ) -> Result<RollupConfig, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RollupConfig

fn eq(&self, other: &RollupConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
