Open source →REVM v42.0.0 Release Notes
Date: 2026-07-23
v114 aligns REVM with Glamsterdam devnet-7 and the
[email protected]fixtures — allstate_testsand
blockchain_testspass. 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 flatTX_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:
SSTOREmust 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::CodeChangenow records and restores the previous code hash and
bytecode, fixing a phantom BAL code write on reverted 7702 delegation changes.

Open source →date: 11.06.2026
All crates are now versioned in lockstep, starting at 41.0.0 — hence the version jump (e.g.

Other highlights:
- SSTORE gas accounting hook (#3734, #3750),
StateBuilder::with_bundle_update_if(#3729),Account::is_changed(#3727) - Commit perf improvements (#3732)

analyze_legacy(#3752) and a const-eval panic inpop_address(#3735)
