Crate foundry_evm_networks 

foundry-evm-networks

Runtime selection and shared configuration for Foundry’s EVM network families.

NetworkConfigs describes the active execution profile selected by configuration, CLI flags, hardforks, or fork endpoint discovery. Cargo features only determine which optional NetworkVariant values are compiled into a binary; they do not select a network at runtime.

Concrete Alloy network and EVM factory types are associated by FoundryEvmNetwork in foundry-evm-core. See the custom EVM integration guide for the cross-crate ownership and state-lifecycle contract.

Constants

BASE_CODE_SENTINEL_ADDRESSES

Fixed Base precompiles that expose at least one function returning no data.

BASE_PRECOMPILES 🔒

BASE_PRECOMPILE_ADDRESSES

All fixed Base precompile addresses.

BSC_MAINNET_CHAIN_ID 🔒

BSC_MAINNET_HABER_TIMESTAMP 🔒

BSC_MAINNET_OSAKA_TIMESTAMP 🔒

BSC_P256_ADDRESS 🔒

BSC secp256r1 precompile address introduced by the Haber hardfork.

BSC_TESTNET_CHAIN_ID 🔒

BSC_TESTNET_HABER_TIMESTAMP 🔒

BSC_TESTNET_OSAKA_TIMESTAMP 🔒

MONAD_CHEATCODE_ADDRESS

The Monad cheatcode handler address.

MONAD_PRECOMPILES 🔒

MONAD_PRECOMPILE_LABELS 🔒

TEMPO_PRECOMPILES 🔒

TEMPO_PRECOMPILE_ADDRESSES

All well-known Tempo precompile addresses.

Functions

active_base_precompiles

Returns the fixed Base precompiles active at upgrade.

active_tempo_precompile_addresses

Returns the well-known Tempo precompile addresses active at hardfork.

apply_bsc_p256_precompile

Applies the BSC P256 precompile active at the given timestamp.

bsc_p256_precompile 🔒

Returns the BSC P256 precompile for the given timestamp. The outer option distinguishes BSC chains from unrelated chains, while the inner option disables P256 before Haber.

is_base_precompile_active_at

Returns whether a fixed Base precompile is active at upgrade.

is_monad_precompile_active_at

Returns whether a well-known Monad precompile address is active at hardfork.

is_tempo_precompile_active_at

Returns whether a well-known Tempo precompile address is active at hardfork.

resolved_precompile_labels

Returns custom precompile labels for an already resolved execution hardfork. This metadata lookup does not discover or select an execution network.
