March 2026 monthly summary: Delivered security-focused enhancements and API flexibility across two Rust cryptography repositories, enhancing robustness of elliptic-curve operations and expanding scalar construction options. Key work included implementing Elliptic Curve Subgroup Validation in axiom-crypto/openvm-reth-benchmark and introducing a Scalar from u64 and limbs API in commonwarexyz/monorepo. These efforts reduce risk of invalid-curve and small-subgroup attacks, improve cryptographic operation reliability, and enable more performant scalar construction.

Consolidated feature delivery and stability improvements for November 2025, focusing on upgrade readiness and upgrade governance. Delivered Galileo hardfork integration for the Scroll network with timestamp-based activation checks, updated mainnet and Sepolia configurations, and enhanced test coverage to validate the upgrade flow. This work strengthens upgrade reliability, governance compliance, and rollout confidence across environments.

February 2025 — Scroll Proving SDK: Delivered a controlled dependency upgrade for RevM to scroll-evm-executor/v55 with rollback to stable state, balancing access to newer features with system reliability. The changes were implemented in scroll-tech/scroll-proving-sdk to prepare for next-scale capabilities while ensuring release readiness.

January 2025 delivered a major reliability improvement for EVM proof verification by switching from a boolean to a fallible Result return type, enabling granular error handling and richer error reporting across the SDK and CLI. The change also included dependency updates and alignment of verification logic to accommodate the new error model, resulting in clearer debugging and fewer silent failures for users and operators.
