Modules§

arbitrary: The Arbitrary trait crate.
arbitrum: Arbitrum hardfork starting points
constants: OP stack variation of chain spec constants.
error: Error types for the hardforks crate.
ethereum: Ethereum hardfork starting points

Macros§

create_chain_spec: Create a chain spec for a given superchain and environment.
create_superchain_specs: Create chain specs and an enum of every superchain (name, environment) pair.
hardfork: Macro that defines different variants of a chain specific enum. See crate::Hardfork as an example.
key_for: Generates the key string for a given name and environment pair.

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.
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
Head: Describes the current head block.
OpChainSpec: OP stack chain spec type.
OpChainSpecBuilder: Chain spec builder for a OP stack chain.
ParseHardforkError: Error type for hardfork related errors.

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.
OpHardfork: The name of an optimism hardfork.
Superchain: All available superchains as an enum
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: All supported superchains, including both older and newer naming, for backwards compatibility
