bal-devnet-4
Announcements
- bal-devnet-4 target launch: **Wednesday 29.04**.
- BAL benchmark dashboard https://nerolation.github.io/bal-dashboard/. Based on data from https://benchmarkoor.core.ethpandaops.io. Requires benchmarkoor api key.
- EIP-8037: bal-devnet-4 keeps the **static** `cost_per_state_byte = 1174` from bal-devnet-3. The changes to accounting at the frame boundry will land in glamsterdam-devnet-1
- Primary focus of this devnet is **EIP-8037 stabilization**: picking up the spec clarifications, follow-up tests, and the spec decisions from the [state gas accounting review](https://github.com/misilva73/evm-gas-repricings/blob/main/reports/eip-8037/spec_review_state_gas_accounting.md).
- **EIP-7976 and EIP-7981 must be implemented** by all EL clients for bal-devnet-4. Both were added post-ACDT; spec/test side is ready, client implementations are the remaining gate.
- **All 7 EIP-8037 state gas accounting decisions resolved** at Glamsterdam Repricing Breakout #6 (2026-04-15). [Recording](https://www.youtube.com/watch?v=U8RvbLPX188). See "Changes vs. bal-devnet-3" below for the full decision list.
