Summary Introduces a circuit breaker mechanism to protect the protocol during incidents by allowing an authorized admin to pause sensitive operations while ensuring user funds remain accessible.
Key Changes
Circuit Breaker: Added an EmergencyStop state to pause create_stream and top_up_stream
Admin Control: Implemented an initialize function to set a protocol administrator who can toggle emergency mode via
set_emergency_mode
Safe Mode Operations: Ensured withdraw and cancel_stream remain functional even when the emergency stop is active, allowing users to safely manage existing streams.
Events & Errors: Added EmergencyStopToggledEvent and EmergencyStopEnabled error for transparent on-chain behavior.
Testing: Added 4 new test cases covering admin authorization, operation blocking, and safe-mode withdrawals.
Verification Results
Unit Tests: 14 tests passing.
Quality Checks: cargo clippy and cargo fmt are clean.
Build: Successfully compiled to WASM release.
