}

Defines core blockchain settings per block.

Tailors unique settings for each network based on its genesis block and superchain configuration.

This struct bridges the interface between the ChainConfig defined in the superchain-registry and the ChainConfig defined in op-geth.

Fields

name: String

Chain name (e.g. “Base”)

l1_chain_id: u64

L1 chain ID

public_rpc: String

Chain public RPC endpoint

sequencer_rpc: String

Chain sequencer RPC endpoint

explorer: String

Chain explorer HTTP endpoint

superchain_level: SuperchainLevel

Level of integration with the superchain.

governed_by_optimism: bool

Whether the chain is governed by optimism.

superchain_time: Option<u64>

Time of when a given chain is opted in to the Superchain. If set, hardforks times after the superchain time will be inherited from the superchain-wide config.

data_availability_type: String

Data availability type.

chain_id: u64

Chain ID

batch_inbox_addr: Address

Chain-specific batch inbox address

block_time: u64

The block time in seconds.

seq_window_size: u64

The sequencer window size in seconds.

max_sequencer_drift: u64

The maximum sequencer drift in seconds.

gas_paying_token: Option<Address>

Gas paying token metadata. Not consumed by downstream OPStack components.

hardfork_config: HardForkConfig

Hardfork Config. These values may override the superchain-wide defaults.

optimism: Option<BaseFeeConfig>

Optimism configuration

alt_da: Option<AltDAConfig>

Alternative DA configuration

genesis: ChainGenesis

Chain-specific genesis information

roles: Option<Roles>

Roles

addresses: Option<AddressList>

Addresses

Implementations

impl ChainConfig

pub fn base_fee_params(&self) -> BaseFeeParams

Returns the base fee params for the chain.

pub fn canyon_base_fee_params(&self) -> BaseFeeParams

Returns the canyon base fee params for the chain.

pub fn base_fee_config(&self) -> BaseFeeConfig

Returns the base fee config for the chain.

pub fn load_op_stack_rollup_config(&self) -> RollupConfig

👎Deprecated since 0.2.1: please use as_rollup_config instead

Loads the rollup config for the OP-Stack chain given the chain config and address list.

pub fn as_rollup_config(&self) -> RollupConfig

Loads the rollup config for the OP-Stack chain given the chain config and address list.

Trait Implementations

impl Clone for ChainConfig

fn clone(&self) -> ChainConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainConfig

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

Formats the value using the given formatter.

impl Default for ChainConfig

fn default() -> ChainConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChainConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChainConfig

fn eq(&self, other: &ChainConfig) -> 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.

impl Serialize for ChainConfig

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ChainConfig

impl StructuralPartialEq for ChainConfig
