2025-08 Monthly Summary for okx/op-geth: Focused on delivering a robust gas estimation improvement for high gas limit scenarios on the Osaka chain under EIP-7825. The estimator now properly caps the upper bound at maxTxGas and includes special handling for ErrGasLimitTooHigh to guide a binary search toward the lowest feasible gas limit. This enhances accuracy, reduces failed transactions due to gas estimation, and improves reliability for Osaka deployments.

April 2025 monthly summary for ethereum-optimism/infra: Improved observability by correcting block payload signing metrics and replacing the incorrect transaction-level metric; dashboards and alerts now reflect the actual block signing activity, enabling faster incident response and data-driven capacity planning.

January 2025 — Monthly summary for ethereum-optimism/infra focusing on reliability improvements in op-signer transaction logging and dependency hygiene.

December 2024 monthly summary: Delivered protocol-aligned signing capabilities and a critical Holocene activation fix across three repositories, reinforcing security, reliability, and business value. Notable outcomes include a Holocene Activation Bug Fix to use the parent block timestamp, remote signing integration for block payload signing, and infrastructure-level signing support with updated docs and configs. These changes improve accuracy of base fee calculations during Holocene, strengthen signing security, and streamline deployment across environments.
