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.

BSC_TESTNET_OSAKA_TIMESTAMP 🔒

MONAD_CHEATCODE_ADDRESS

The Monad cheatcode handler address.

MONAD_CHEATCODE_ADDRESSES 🔒

MONAD_PRECOMPILES 🔒

MONAD_PRECOMPILE_LABELS 🔒

TEMPO_PRECOMPILES 🔒

TEMPO_PRECOMPILE_ADDRESSES

All well-known Tempo precompile addresses.

Functions

active_tempo_precompile_addresses

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

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_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.
