REVM v42.0.0 Release Notes

Date: 2026-07-23

v114 aligns REVM with Glamsterdam devnet-7 and the
[email protected] fixtures — all state_tests and
blockchain_tests pass. All crates are released as 42.0.0.

EIP-2780 runtime gas phase (#3795, ethereum/EIPs#11844)

State-dependent transaction charges move out of intrinsic gas into a runtime
phase applied as the first frame is entered. Gated on
CfgEnv::enable_amsterdam_eip2780; older forks are unchanged.

• Create transactions: new-account state gas is charged at runtime, only
  when the deployment target does not exist; an initcode revert/halt unwinds it.
• EIP-7702: the pessimistic per-auth intrinsic charge becomes an intrinsic
  REGULAR_PER_AUTH_BASE_COST (7,816) plus per-authority runtime charges, with
  no refunds. The delegation target now follows the normal EIP-2929 warm/cold
  model.
• Runtime out-of-gas no longer invalidates the transaction: it is included
  as an OOG halt consuming all gas, with all runtime state changes (including
  applied delegations) reverted, and returns the EIP-8037 reservoir.
• Charging is incremental and stops at the first unaffordable charge, so later
  authorities and a cold delegation target are never loaded and stay out of the
  EIP-7928 BAL.

Other devnet-7 alignment (#3795)

• #11836: calldata floor anchored
  on the decomposed intrinsic base instead of flat TX_BASE.
• #11891: 7702 ACCOUNT_WRITE
  charged on first write per authority, skipped only when already paid.
• #11858: CREATE/CREATE2
  account-creation state gas charged conditionally at access in the creating
  frame, refilled LIFO when the create fails.
• #11854: SSTORE must cover the
  slot access cost before the implicit read; an unaffordable cold access keeps
  the slot out of the block access list.
• EIP-8246 replaces the EIP-7708 delayed burn; system-contract addresses
  updated per EIP-8282.
• JournalEntry::CodeChange now records and restores the previous code hash and
  bytecode, fixing a phantom BAL code write on reverted 7702 delegation changes.

Other changes

• feat(database): database fallback mode for BAL misses (#3754).
• feat: configurable max refund quotient (#3757); BAL account change slices (#3762).
• fix(inspector): EIP-7708 transfer logs reach the inspector (#3816); stale
  SELFDESTRUCT journal entries ignored (#3805); journal finalized on error so the
  EIP-2929 warm set does not leak (#3780).
• fix: GasTracker used-gas underflow (#3813); is_empty preserved on 7702
  accounts in load_account_delegated (#3802); storage original_value
  re-baselined only across tx boundaries (#3746); bytecode iterator fixes
  (#3800, #3792).
• perf: fewer bounds checks in precompile parsing (#3784); no intermediate BAL
  account allocation (#3775); no double cloning in take_n_reverts (#3539).
• chore(deps): crossbeam-epoch 0.9.20 for RUSTSEC-2026-0204 (#3804).

date: 11.06.2026

All crates are now versioned in lockstep, starting at 41.0.0 — hence the version jump (e.g. revm-bytecode 11.0.1 → 41.0.0). Released by #3711 and #3753; full diff v112...v113.

Breaking:

• TransientStorage is now a newtype over AddressMap<StorageKeyMap<StorageValue>> (#3736)
• OnStateHook::on_state takes EvmState by value; TransitionAccount gained a storage generic (#3732)
• GasStateTr removed, superseded by the SSTORE gas hook (#3750)

Other highlights:

• SSTORE gas accounting hook (#3734, #3750), StateBuilder::with_bundle_update_if (#3729), Account::is_changed (#3727)
• Commit perf improvements (#3732)
• Fix out-of-bounds pointer in analyze_legacy (#3752) and a const-eval panic in pop_address (#3735)
