Crate reth_chainspec

The spec of an Ethereum network

Modules

arbitrary

Re-export for convenience The Arbitrary trait crate.

Macros

hardfork

Re-export for convenience 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

Re-export for convenience 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

Re-export for convenience A container for pretty-printing a list of hardforks.

EnrForkIdEntry

Re-export for convenience 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

Re-export for convenience A type allowing to configure activation ForkConditions for a given list of EthereumHardforks.

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

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

ForkHash

Re-export for convenience CRC32 hash of all previous forks starting from genesis block.

ForkId

Re-export for convenience A fork identifier as defined by EIP-2124. Serves as the chain compatibility identifier.

ForkTransition

Re-export for convenience Represents a transition from one fork to another

HardforkBlobParams

A container for hardforks that use eip-7804 blobs.

Head

Re-export for convenience 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

Re-export for convenience The name of an Ethereum hardfork.

ForkCondition

Re-export for convenience The condition at which a fork is activated.

ForkFilterKey

Re-export for convenience How to filter forks.

NamedChain

An Ethereum EIP-155 chain.

ValidationError

Re-export for convenience Reason for rejecting provided ForkId.

Constants

MAINNET_PRUNE_DELETE_LIMIT

Mainnet prune delete limit.

MIN_TRANSACTION_GAS

Gas per transaction not creating a contract.

Statics

DEV

Dev testnet specification

DEV_HARDFORKS

Re-export for convenience Dev hardforks

HOLESKY

The Holesky 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

Re-export for convenience Helper methods for Ethereum forks.

Hardfork

Re-export for convenience Generic hardfork trait.

Hardforks

Re-export for convenience Generic trait over a set of ordered hardforks

Functions

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_idstest-utils

Verifies ChainSpec configuration against expected data in given cases.
