Evidence

Strengthening XCM Security & Execution

• #7200 - XCM: Deny barrier checks for nested XCMs
  • Security Enhancement: Strengthened XCM validation by preventing unauthorised nested XCM executions, reducing potential attack vectors. Closes #7148 - Investigate better support for filtering XCM programs with Barrier.
• #7351 - PoC(XCM): Deny Nested XCM Barriers
  • Proof of Concept: Explored stricter XCM validation mechanisms to prevent bypassing of security barriers, improving overall protocol robustness.

Developer Experience & Usability

• #883 - Fix Basic Usage code in Chopsticks
  • Documentation Fix: Resolved incorrect example in Chopsticks to enhance usability and correctness for developers.

Improving Observability & Debugging

• #7234 - Add EventEmitter to XCM executor
  • Enhanced Traceability: Verified and refined event emission logic in XCM execution, enabling better tracking of cross-chain message flows. Closes #6851 - Implement error-specific events.
• #7003 - Enhance logging for XCM filters, helpers, and matchers
  • Debugging Enhancement: Improved logging visibility for XCM components, making debugging more efficient for developers.
• #7594 - Enhance XCM Debugging with Log Capture in Unit Tests
  • Test Debugging Improvement: Introduced a lightweight log-capturing mechanism for XCM unit tests, simplifying debugging through structured log assertions. Closes #6125 - Enable unit test logging.
• #7769 - Ensure Logs Are Captured for Assertions and Printed During Tests
  • Enhanced Test Logging: Ensures logs up to TRACE level are captured (for assertions) and printed (for visibility) during test execution, improving developer tracing and debugging.
• #7734 - Simplify event assertion with predicate-based check
  • Improved Test Flexibility: Introduced contains_event to simplify event assertions, reducing redundancy and improving test flexibility.

Ongoing Work & Future Contributions

• #6119 - XCM Observability & Debuggability
  • Goal: Enhancing XCM traceability through structured event emissions, improved logging, and debugging tools—empowering developers to diagnose cross-chain issues faster.
