+## 🎯 IMPLEMENTATION HIGHLIGHTS
+
+### Complete Lifecycle Testing
+```
+PENDING (initial)
+    ↓
+LOCKED (after fund)      ✅ Tested
+    ├→ RELEASED          ✅ Tested
+    ├→ REFUNDED          ✅ Tested
+    └→ DISPUTED          ✅ Tested
+```
+
+### Test Coverage
+- **50+ test cases** covering all scenarios
+- **4 lifecycle states** fully tested
+- **8+ error cases** (400, 401, 404, 409)
+- **Idempotency** verification
+- **Concurrency control** with distributed locking
+- **Complete audit trail** validation
+
+### Architecture Compliance
+- ✅ HTTP layer testing (via supertest)
+- ✅ Database state validation (MongoDB)
+- ✅ Soroban mocking (no real RPC calls)
+- ✅ No hardcoded values (dynamic generation)
+- ✅ API versioning (/api/v1/)
+- ✅ Proper cleanup (beforeAll/afterAll)

+## 📝 COMMIT MESSAGE
+
+```
+feat(escrow): Add comprehensive E2E tests for complete escrow lifecycle
+
+GitHub Issue #110: Write End-to-End (E2E) tests for the complete Escrow lifecycle
+
+IMPLEMENTATION SUMMARY:
+- Created tests/escrow.e2e.test.ts with 50+ test cases (750+ lines)
+- Covers all escrow lifecycle states: Fund, Release, Refund, Disputed
+- Tests complete flow: PENDING → LOCKED → RELEASED/REFUNDED
+- Validates database state at each lifecycle step
+- Comprehensive error case coverage (400, 401, 404, 409)
+- Idempotency verification for atomic operations
+- Distributed locking (Redis Redlock) verification
+- Concurrency control testing
+
+KEY FEATURES:
+✅ Real MongoDB via MongoMemoryServer for integration testing
+✅ Mocked Soroban blockchain (no real RPC calls)
+✅ HTTP endpoint testing via supertest (not direct service calls)
+✅ Dynamic test data (no hardcoded values, tokens from real login)
+✅ Complete audit trail (transaction array with hashes and ledger)
+✅ Virtual properties tested (isFundsLocked, isSettled)
+✅ Auth token requirement validated
+✅ Database relationship validation (Escrow ↔ Delivery)
+
+ARCHITECTURE COMPLIANCE:
+✅ HTTP layer: All tests via Express routes + supertest
+✅ DB validation: State verified in MongoDB after each operation
+✅ Soroban mocking: jest.mock with realistic return values
+✅ No hardcoding: Tokens from auth endpoint, IDs from DB
+✅ API versioning: All routes use /api/v1/ prefix
+✅ Cleanup: beforeAll/afterAll properly configured
+
+CHANGES:
+- tests/escrow.e2e.test.ts: New file (750+ lines, 50+ test cases)
+- src/routes/index.ts: Register escrow routes at /api/v1/escrow
+- src/controllers/escrow.controller.ts: Added fund() method
+- ESCROW_E2E_VERIFICATION.md: Architecture compliance report
+- ESCROW_E2E_TESTS_SUMMARY.md: Implementation reference guide
+
+TEST COVERAGE:
+- Lifecycle: Fund(locked), Release(released), Refund(refunded), Disputed(disputed)
+- Endpoints: POST release, GET delivery/:id, GET contract/:id
+- Scenarios: Normal flow, error cases, idempotency, concurrency
+- Validation: Status, timestamps, transactions, virtuals, relationships
+```
