Module chainspec

Re-exported from reth_chainspec

Modules

arbitrary

The Arbitrary trait crate.

Macros

hardfork

Macro that defines different variants of a chain specific enum. See crate::Hardfork as an example.

Structs

BaseFeeParams

BaseFeeParams contains the config parameters that control block base fee computation

Chain

Either a known NamedChain or a EIP-155 chain ID.

ChainHardforks

Ordered list of a chain hardforks that implement Hardfork.

ChainInfo

Current status of the blockchain’s head.

ChainSpec

An Ethereum chain specification.

ChainSpecBuilder

A helper to build custom chain specs

DepositContract

PoS deposit contract details.

DisplayHardforks

A container for pretty-printing a list of hardforks.

EnrForkIdEntry

Represents a forward-compatible ENR entry for including the forkid in a node record via EIP-868. Forward compatibility is achieved via EIP-8.

EthereumChainHardforks

A type allowing to configure activation ForkConditions for a given list of EthereumHardforks.

EthereumChainSpecParser

Ethereum chain specification parser.

ForkBaseFeeParams

A type alias to a vector of tuples of Hardfork and BaseFeeParams, sorted by Hardfork activation order. This is used to specify dynamic EIP-1559 parameters for chains like Optimism.

ForkFilter

Filter that describes the state of blockchain and can be used to check incoming ForkIds for compatibility.

ForkHash

CRC32 hash of all previous forks starting from genesis block.

ForkId

A fork identifier as defined by EIP-2124. Serves as the chain compatibility identifier.

ForkTransition

Represents a transition from one fork to another

HardforkBlobParams

A container for hardforks that use eip-7804 blobs.

Head

Describes the current head block.

Enums

BaseFeeParamsKind

A wrapper around BaseFeeParams that allows for specifying constant or dynamic EIP-1559 parameters based on the active Hardfork.

ChainKind

The kind of chain. Returned by Chain::kind. Prefer using Chain instead.

EthereumHardfork

The name of an Ethereum hardfork.

ForkCondition

The condition at which a fork is activated.

ForkFilterKey

How to filter forks.

NamedChain

An Ethereum EIP-155 chain.

ValidationError

Reason for rejecting provided ForkId.

Constants

MAINNET_PRUNE_DELETE_LIMIT

Mainnet prune delete limit.

MIN_TRANSACTION_GAS

Gas per transaction not creating a contract.

SUPPORTED_CHAINS

Chains supported by reth. First value should be used as the default.

Statics

DEV

Dev testnet specification

DEV_HARDFORKS

HOLESKY

The Holesky spec

HOODI

The Hoodi spec

MAINNET

The Ethereum mainnet spec

SEPOLIA

The Sepolia spec

Traits

ChainSpecProvider

A trait for reading the current chainspec.

EthChainSpec

Trait representing type configuring a chain spec.

EthereumHardforks

Helper methods for Ethereum forks.

Hardfork

Generic hardfork trait.

Hardforks

Generic trait over a set of ordered hardforks

Functions

chain_value_parser

Clap value parser for ChainSpecs.

make_genesis_header

Helper method building a Header given [Genesis] and ChainHardforks.

once_cell_set

Simple utility to create a thread-safe sync cell with a value set.

test_fork_ids

Verifies ChainSpec configuration against expected data in given cases.
