��# Issue 21: Implement Contract Pause/Resume Functionality
Problem
No way to pause contract in emergency. Must choose between allowing all operations or redeploying.
Solution
- Add
is_paused: bool state variable
- Implement
pause_contract() and resume_contract() (admin only)
- Return
ContractPaused error for all write operations when paused
- Allow read operations even when paused (auditing still works)
Implementation Tasks
Note for Contributors
This is a critical emergency control feature for production deployments. When paused, all write operations return ContractPaused error immediately. Read operations and view calls continue to work, allowing auditing and monitoring during emergencies. Only admin can pause and resume. Emit events when pausing and resuming for governance audit trail. Use a simple bool flag in contract state. Pausing should be fast and lightweight (single state update). Consider implementing pause/resume history in events. The pause mechanism is temporary; for permanent shutdown, use Issue #21 (pause/resume) + admin account compromise response. Test that transitioning between paused/resumed states doesn't lose data or corrupt state.
