 ## 📝 PR Description Template
 
 ```markdown
 ## Summary
-This PR implements "Sign-in with Stellar" authentication using SEP-10 standard for the Harvest Finance platform, addressing issues #162 and #97.
+Adds a platform-wide circuit breaker that allows administrators to instantly halt and resume all deposit and withdrawal operations across all service instances.
 
-## Features Implemented
-- ✅ SEP-10 compliant challenge-response authentication
-- ✅ Freighter wallet integration
-- ✅ Secure signature verification
-- ✅ JWT token integration
-- ✅ Comprehensive test suite (42 tests, 85%+ coverage)
-- ✅ Complete documentation and setup guides
+## Purpose / Motivation
+To protect user funds and limit platform liability during critical events (e.g. smart contract failures, third-party oracle/RPC failures, or malicious exploits), administrators need a quick, highly reliable way to pause all transactional actions (deposits and withdrawals) across all vault types (Stellar, farm-vaults, and insurance-funds).
 
 ## Changes Made
-- **Backend**: Stellar strategy, auth endpoints, DTOs, guards
-- **Frontend**: StellarAuth component, login page updates, auth store integration
-- **Tests**: Unit tests, integration tests, component tests
-- **Documentation**: Setup guides, API docs, test reports
-
-## Environment Variables Required
-```env
-# Backend
-STELLAR_SERVER_SECRET=your_server_secret
-STELLAR_NETWORK_PASSPHRASE=Test SDF Network ; September 2015

-# Frontend
-NEXT_PUBLIC_API_URL=http://localhost:5000/api/v1

+- **PlatformCircuitBreakerService**: Implements breaker state validation, activation (`open`), and deactivation (`close`) with state persistence in Redis cache.
+- **PlatformCircuitBreakerGuard**: Throws a `503 Service Unavailable` with a clear message `Maintenance Mode` when the circuit breaker is active.
+- **Admin Endpoints**: Adds `POST /api/v1/admin/platform/circuit-breaker/open` and `/api/v1/admin/platform/circuit-breaker/close` with proper admin role checking and audit trail logging.
+- **Controller Protections**: Applied `@UseGuards(PlatformCircuitBreakerGuard)` to deposit and withdrawal endpoints in:
+  - `VaultsController`
+  - `FarmVaultsController`
+  - `InsuranceFundController`
+- **Unit and Integration Tests**:
+  - `platform-circuit-breaker.service.spec.ts`
+  - `platform-circuit-breaker.guard.spec.ts`
+  - `circuit-breaker.controller.spec.ts`
+  - `circuit-breaker.e2e-spec.ts` (End-to-end verification of endpoint blocking, propagation via Redis, and rapid toggles)
 
 ## How to Test
-1. Install Freighter wallet extension
-2. Set up environment variables
-3. Run backend and frontend servers
-4. Navigate to login page and select "Stellar" auth method
-5. Connect wallet and authenticate
-
-## Security Features
-- SEP-10 compliance
-- Challenge expiration (5 minutes)
-- Server and client signature verification
-- Replay attack prevention
-- Network validation
-
-## Test Coverage
-- 42 total tests
-- 85%+ code coverage
-- All security scenarios covered
-- Performance benchmarks met
-
-Fixes #162 #97
+1. Set up env variables and ensure Redis is running.
+2. Run backend E2E tests:
+   ```bash
+   npm run test:e2e test/circuit-breaker.e2e-spec.ts
+   ```
+3. Test manually by authenticating as admin:
+   - Open circuit breaker: `POST /api/v1/admin/platform/circuit-breaker/open`
+   - Attempt deposit or withdraw; confirm it fails with `503 Service Unavailable (Maintenance Mode)`.
+   - Close circuit breaker: `POST /api/v1/admin/platform/circuit-breaker/close`
+   - Attempt deposit or withdraw; confirm it succeeds.
