PROFILE

Marija Mijailović

Over five months, this developer contributed to the foundry-rs/starknet-foundry and 0xPolygonMiden repositories, focusing on command-line interface enhancements, security improvements, and robust testing frameworks. They implemented user-facing verification prompts with security warnings and expanded StarkNet contract verification to support class hashes, streamlining developer workflows in Rust. In the 0xPolygonMiden projects, they delivered new CLI commands for executing and testing account procedures, improved argument parsing, and enhanced transaction output. Their work also strengthened the Miden protocol’s test framework by migrating macros to helper methods and extending assertion capabilities, resulting in clearer, more maintainable tests and improved error handling.

April 2026 monthly summary for 0xPolygonMiden/miden-client: Delivered a consolidated Miden CLI Call Command with enhanced argument handling and improved transaction output, enabling reliable, auditable invocation of account procedures. This work included distinct account and procedure argument separation, a dedicated miden-cli call command, improved parsing support (Felt vs u64), and extended test scaffolding for call-test. Major CI fixes and signature-argument validation were implemented to reduce build failures and ensure correct invocation patterns. The changes lay groundwork for robust automated testing and smoother developer workflows, aligning with ongoing deployment automation and governance requirements.

Mar 1, 2025

Monthly summary for 2025-03 focusing on the foundry-rs/starknet-foundry repository. Key feature delivered: StarkNet contract verification by class hash. Implemented support for verifying StarkNet contracts using their class hash in addition to contract address; sncast verify now accepts --class-hash to specify the contract's class hash for verification with the Walnut verifier, increasing flexibility of verification. Commit reference: 63645532724b4d9197c0d2705452227b5da43a65 with message "Support for the verification with class hash (#2906)". Impact: expands verification options, streamlines workflows for developers, and improves validation coverage across verification paths.

Dec 1, 2024

December 2024 was marked by a targeted UX/security enhancement in the Walnut Verifier within the foundry-rs/starknet-foundry repo. Delivered a user-facing verification prompt update that includes critical security warnings about handling sensitive information and file uploads, accompanied by updates to the verification process documentation to reflect the new prompts and guidance. This helps reduce data exposure risk and clarifies proper verification workflows for users and operators. Major bugs fixed: None reported or completed in this period. Overall impact and accomplishments: Strengthened security posture of the verification flow, improved user guidance, and ensured documentation stays aligned with UX changes. The change supports safer file handling, clearer warning messaging, and better onboarding—leading to reduced support overhead and fewer misconfigurations across deployments in Foundry’s StarkNet integration. Technologies/skills demonstrated: UX-focused prompt design, security-first approach to verification flows, Rust-based repository work in foundry-rs/starknet-foundry, documentation writing and maintenance, and traceable change management via a committed change (commit 0a935e322189d8b779393c877c364ebde10b1231).
