Enum BaseUpgrade 

#[non_exhaustive]
pub enum BaseUpgrade {
    Bedrock,
    Regolith,
    Canyon,
    Delta,
    Ecotone,
    Fjord,
    Granite,
    Holocene,
    PectraBlobSchedule,
    Isthmus,
    Jovian,
    Azul,
    Beryl,
    Cobalt,
    Denim,
    Zenith,
}

The canonical Base network upgrade.

This single enum spans two domains:

• the execution fork ladder (BaseUpgrade::EXECUTION_VARIANTS) that maps onto the reth/revm hardfork schedule, and
• the contract-backed upgrade set (BaseUpgrade::CONTRACT_VARIANTS) that is keyed by the L1 upgrade-signal contract hardforkId strings and the genesis [UpgradeConfig] timestamp fields.

Real network upgrades are listed in chronological order. Bedrock is execution-only (block-activated, not contract-backed), while Delta and PectraBlobSchedule are contract-backed config upgrades that do not change EVM execution and therefore never enter the execution fork ladder.

Denim is the fourth Base-specific network upgrade. It is unscheduled for now, but it is a first-class upgrade: contract-backed and part of the execution fork ladder, so live chains can activate it once an activation time is configured.

Zenith is a hardfork for future experimental features. It is genesis-configurable but not contract-backed, since the L1 upgrade-signal contract does not yet recognise it.

When building a list of upgrades for a chain, it’s still expected to zip with EthereumHardfork.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl BaseUpgrade

pub const VARIANTS: &'static [BaseUpgrade]

All hardfork variants

pub const fn name(&self) -> &'static str

Returns variant as str.

impl BaseUpgrade

pub const LATEST: BaseUpgrade = Self::Beryl

Latest Base upgrade used by default.

pub const EXECUTION_VARIANTS: [BaseUpgrade; 13]

The execution fork ladder, in activation order.

These are the upgrades that participate in the reth/revm hardfork schedule. Excludes the contract-only Delta and PectraBlobSchedule upgrades, and Zenith, which does not yet change EVM execution.

pub const CONTRACT_VARIANTS: [BaseUpgrade; 14]

The contract-backed upgrade set, in activation order.

These are the upgrades addressable by the L1 upgrade-signal contract and stored in the genesis [UpgradeConfig]. Excludes block-activated Bedrock and Zenith, which is activated via genesis config only until the L1 upgrade-signal contract is updated to recognise it.

Order is load-bearing: map_schedule and ScheduleId::pin attribute onchain schedule entries to hardforks by position, and the ProtocolVersions contract keys upgrades by ascending append-only registration id with names kept offchain. This order MUST match the contract’s registration order — reordering silently misattributes every activation timestamp. Only ever append.

pub const fn is_execution(self) -> bool

Returns true if this upgrade participates in the execution fork ladder.

pub const fn is_contract_backed(self) -> bool

Returns true if this upgrade is contract-backed (i.e. signaled by the L1 upgrade-signal contract and stored in [UpgradeConfig]). False for block-activated Bedrock and for Zenith, which is activated via genesis config only until the L1 upgrade-signal contract is updated.

pub const fn execution_idx(self) -> Option<usize>

Returns this upgrade’s index within EXECUTION_VARIANTS, or None for contract-only upgrades that are absent from the execution fork ladder.

pub const fn contract_id(self) -> &'static str

Returns the canonical snake_case contract upgrade ID used by the L1 upgrade-signal contract and metrics.

Note this differs from name (PascalCase), which is the reth/execution hardfork identity.

pub const fn execution_hardfork(self) -> Option<EthereumHardfork>

Returns the Ethereum execution hardfork activated by this upgrade, if any.

pub const fn from_ethereum_hardfork( fork: EthereumHardfork, ) -> Option<BaseUpgrade>

Returns the Base upgrade that carries the given Ethereum hardfork on Base.

pub fn from_contract_fork_name(name: &str) -> Option<BaseUpgrade>

Returns the contract-backed upgrade represented by an execution, Base, or contract alias name. Returns None for unknown names and for non-contract-backed upgrades (Bedrock).

pub fn normalized_hardfork_id(upgrade_id: &str) -> String

Normalizes a contract upgrade ID for matching (lowercase, stripping whitespace, _, -).

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

Returns the active upgrade at the given timestamp for the specified chain.
