Enum MonadHardfork 

#[repr(u8)]
pub enum MonadHardfork {
    MonadEight = 100,
    MonadNine = 101,
    MonadNext = 102,
}

Monad hardfork identifier.

Variants are ordered by activation order. Lower discriminant = earlier hardfork.

Variants

MonadEight = 100

Monad launch hardfork (based on Prague).

MonadNine = 101

MIP-3, MIP-4, MIP-5

MonadNext = 102

Next development spec

Implementations

impl MonadHardfork

pub const fn into_eth_spec(self) -> SpecId

Returns the underlying Ethereum SpecId this Monad hardfork is built upon.

Used internally to:

• Get the base instruction table (before Monad gas overrides)
• Get the base precompiles (before Monad gas overrides)
• Check Ethereum feature availability (e.g., blob support)

Note: This returns the foundation spec, not an equivalence. Future Monad hardforks may add features beyond the base Ethereum spec.

pub const fn is_enabled_in(self, other: MonadHardfork) -> bool

Returns true if self is enabled when the active spec is other.

A hardfork is enabled when its discriminant is ≤ the active spec’s discriminant, i.e. it was activated at the same time or earlier.

pub const fn from_chain_and_timestamp( chain_id: u64, timestamp: u64, ) -> Option<MonadHardfork>

Returns the active Monad hardfork at the given timestamp for the specified chain.

pub const fn mainnet_activation_timestamp(&self) -> Option<u64>

Retrieves the activation timestamp for this hardfork on mainnet.

pub const fn testnet_activation_timestamp(&self) -> Option<u64>

Retrieves the activation timestamp for this hardfork on testnet.
