}

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”)

chain_id: u64

Chain ID

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.

standard_chain_candidate: bool

Toggles standard chain validation checks on for this chain, even if it is a frontier chain.

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.

batch_inbox_addr: Address

Chain-specific batch inbox address

superchain: String

Superchain is a simple string to identify the superchain. This is implied by directory structure, and not encoded in the config file itself.

chain: String

Chain is a simple string to identify the chain, within its superchain context. This matches the resource filename, it is not encoded in the config file itself.

hardfork_configuration: HardForkConfiguration

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

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.

data_availability_type: String

Data availability type.

optimism: Option<OpBaseFeeParams>

Optimism configuration

alt_da: Option<AltDAConfig>

Alternative DA configuration

genesis: ChainGenesis

Chain-specific genesis information

addresses: Option<AddressList>

Addresses

gas_paying_token: Option<Address>

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

Implementations

impl ChainConfig

pub fn set_missing_fork_configs(&mut self, defaults: &HardForkConfiguration)

Set missing hardfork configurations to the defaults, if the chain has a superchain_time set. Defaults are only used if the chain’s hardfork activated after the superchain_time.

pub fn load_op_stack_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 copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChainConfig

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

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<Self, __D::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 ==.

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ChainConfig

impl StructuralPartialEq for ChainConfig
