September 2025 monthly summary focusing on key accomplishments and business value across the 0xPolygonMiden repositories miden-client and miden-base. The month highlights two cross-repo deliverables that improve integration, persistence, and cryptographic workflows.

August 2025 performance snapshot for 0xPolygonMiden/miden-client: Delivered the SigningInputs model in the web client to centralize and abstract signing inputs for cryptographic operations. This design enables signing of transaction summaries, arbitrary data, and blind inputs, strengthening security and expanding web signing capabilities. The work is documented in commit 7af734d77ddbcc39aef5c915bd391c1c1e7e4dae (feat: web-client) Add SigningInputs model (#1160).

July 2025 accomplishments for 0xPolygonMiden/miden-client focused on expanding client-side cryptography capabilities. Delivered exposure of cryptographic signatures in the WASM interface, including serialization/deserialization for public keys, secret keys, and signatures, plus signing and verification APIs, enabling secure offline operations and easier downstream integrations. This work reduces server-side crypto loads, improves security posture, and accelerates end-user workflows.

June 2025 — Focused work on 0xPolygonMiden/miden-client delivering WebAssembly performance optimization and secure wallet RNG, laying groundwork for faster, more secure wallet operations and easier maintenance.

November 2024: Delivered a Fee Migration Strategy with a Consensus Versioned Cost Model for ProvableHQ/snarkVM, enabling dynamic fee calculations based on network version (V1/V2). Updated base costs and added tests to validate migration behavior and nested cost calculations. Ensured imports use legacy fees during migration to maintain backward compatibility. Addressed PR feedback and resolved clippy issues to improve code quality. Stabilized the verify transaction tests related to migration changes. This work reduces fee-related risk during protocol upgrades and improves predictability for developers and users while laying groundwork for smoother transitions to future consensus versions.
