ACDT #87 · Devnet 7 gas raised to 300M
AllCoreDevs - Testing #087 · 2026-07-13
Launch Glamsterdam Devnet 7 with 300M gas
It was decided to raise the Glamsterdam Devnet 7 gas limit from 200M to 300M and launch soon, and the EIP-8037 bug fix, which had allowed blocks to be inflated up to 8 times, is already reflected in spec 7.2 and included in Devnet 7.
Why it matters
Raising the gas limit to 300M lets heavier blocks test the slot structure and new features closer to real conditions, and the gas limit is now tied to the attestation deadline, so CL developers also take part in deciding it. The EIP-8037 bug fix corrects the wrong assumption that produced far larger blocks than expected, which raises confidence in verification before mainnet.
Decisions
- Devnet 7 gas 300M: The Devnet 7 gas limit was raised from 200M to 300M. Test blocks can be filled more heavily, so new features and the slot structure can be tested closer to real conditions.
- EIP-8037 fix: The fix for the EIP-8037 floor cost bug, which let blocks be inflated up to 8 times the expected maximum, was included in Devnet 7. It is already merged into spec 7.2.
- EIP terminology cleanup: It was decided to proceed with the EIP document terminology cleanup (renaming regular gas to execution gas, merging log costs) targeting Devnet 8. Consensus rules do not change, only the documents are edited.
Discussion
Devnet 7 gas limit to 300M
This was the session to decide what block gas limit to use for testing ahead of the Devnet 7 launch.
Outcome: Confirmed 00:18:37
EIP-8037 floor cost block-level fix
A discussion on whether to include in devnet7 a fix for a bug where the floor cost applied only per transaction, which allowed blocks to be much larger than expected.
EIP document terminology cleanup
A discussion asking whether, with the devnet nearing its end, the EIP documents should be refined for clarity while leaving the consensus rules unchanged.
