+
+## 🚨 CRITICAL SAFETY WARNING 🚨
+
+**NEVER run tests without isolated storage!** Integration tests were previously written in a dangerous way that could **DELETE YOUR ACTUAL WALLET DATA AND SAFE CONFIGURATIONS**.
+
+### Mandatory Safety Rules:
+
+1. **ALL integration tests MUST use `createTestStorage()`** from `src/tests/helpers/test-storage.ts`
+2. **NEVER instantiate storage classes without the `cwd` option** in test mode
+3. **ALWAYS verify tests are using `/tmp` directories** before running
+4. **Backup your config before running tests** if unsure
+
+The storage classes now have built-in safety checks that will throw an error if you try to use non-temp directories in test mode.
+
+### Safe Test Pattern (REQUIRED):
+
+```typescript
+import { createTestStorage } from '../helpers/test-storage.js'
+import { WalletStorageService } from '../../storage/wallet-store.js'
+
+describe('My Test', () => {
+  let testStorage: ReturnType<typeof createTestStorage>
+  let walletStorage: WalletStorageService
+
+  beforeEach(() => {
+    // REQUIRED: Create isolated test storage
+    testStorage = createTestStorage('my-test')
+    walletStorage = new WalletStorageService({ cwd: testStorage.configDir })
+  })
+
+  afterEach(() => {
+    // REQUIRED: Cleanup test directories
+    testStorage.cleanup()
+  })
+})
+```
+
+### Dangerous Pattern (FORBIDDEN):
+
+```typescript
+// ❌ NEVER DO THIS IN TESTS - touches real user config!
+const walletStorage = new WalletStorageService()
+walletStorage.getAllWallets().forEach(w => walletStorage.removeWallet(w.id)) // DELETES REAL DATA!
+```
+
+## Pre-Commit Checklist
+
 Run the following commands before committing:
 
-* npm run lint
-* npm run format
-* npm run typecheck
-* npm run test
+```bash
+npm run lint          # Check code style and potential issues
+npm run format        # Format code with Prettier
+npm run typecheck     # Run TypeScript type checking
+npm run test          # Run unit and integration tests
+```
 
 If any errors pop up, fix them before committing.
 
+## Development Workflow
+
+### Testing
+
+#### Unit Tests
+Unit tests are located in `src/tests/unit/` and cover:
+- Services (`src/services/*`)
+- Utilities (`src/utils/*`)
+- Storage (`src/storage/*`)
+
+Run unit tests:
+```bash
+npm test                    # Run all tests (excluding integration/e2e)
+npm test -- --watch         # Run tests in watch mode
+npm test -- --ui            # Run tests with Vitest UI
+```
+
+#### Integration Tests
+Integration tests are in `src/tests/integration/` and test:
+- Full workflows (wallet import, Safe creation, transaction lifecycle)
+- Service integration
+- Storage integration
+- Transaction building and parsing
+
+Run integration tests explicitly (they require blockchain access):
+```bash
+npm test src/tests/integration/integration-*.test.ts
+```
+
+#### E2E Tests
+E2E tests verify the CLI commands work correctly:
+- `e2e-cli.test.ts` - Basic CLI functionality
+- `e2e-wallet-commands.test.ts` - Wallet operations
+- `e2e-config-commands.test.ts` - Configuration management
+- `e2e-account-commands.test.ts` - Account operations
+- `e2e-tx-commands.test.ts` - Transaction commands
+- `integration-full-workflow.test.ts` - Complete end-to-end workflow
+
+Run E2E tests:
+```bash
+# Build the CLI first
+npm run build
+
+# Run E2E tests (requires TEST_WALLET_PK environment variable)
+TEST_WALLET_PK=0x... npm test src/tests/integration/e2e-*.test.ts
+```
+
+#### Coverage
+Check test coverage:
+```bash
+npm test -- --coverage       # Generate coverage report
+```
+
+Coverage thresholds are configured in `vitest.config.ts`:
+- Lines: 30%
+- Functions: 69%
+- Branches: 85%
+- Statements: 30%

+```
+
+### Configuration and Storage
+
 If in the course of development or testing you need to clear or modify the local configs, back up the existing ones first, and restore them when finished.
+
+Configuration is stored in:
+- Config: `~/.config/@safe-global/safe-cli/config.json`
+- Data: `~/.local/share/@safe-global/safe-cli/`
+
+For testing with isolated directories, use `XDG_CONFIG_HOME` and `XDG_DATA_HOME`:
+```bash
+XDG_CONFIG_HOME=/tmp/test-config XDG_DATA_HOME=/tmp/test-data npm run dev
+```
+
+### Adding New Features
+
+1. **Create the service/utility** - Write the core logic with tests
+2. **Add storage layer** (if needed) - Implement data persistence
+3. **Create command** - Implement the CLI command in `src/commands/`
+4. **Add E2E test** - Verify the command works end-to-end
+5. **Update documentation** - Add to README if user-facing
+
+### Debugging
+
+Run CLI in development mode:
+```bash
+npm run dev -- <command>            # Run with tsx (fast reload)
+DEBUG=* npm run dev -- <command>    # Run with debug logging
+```
+
+Build and run production version:
+```bash
+npm run build
+node dist/index.js <command>
+```
+
+### Code Style
+
+- TypeScript strict mode enabled
+- ESLint for linting
+- Prettier for formatting
+- Husky for pre-commit hooks
+- lint-staged for staged file checking
+
+### Common Patterns
+
+#### Error Handling
+Use custom error classes from `src/utils/errors.ts`:
+```typescript
+import { ValidationError, SafeError } from '../utils/errors.js'
+
+throw new ValidationError('Invalid address format')
+throw new SafeError('Failed to create Safe')
+```
+
+#### Address Validation
+Support both plain and EIP-3770 addresses:
+```typescript
+import { parseEIP3770Address } from '../utils/eip3770.js'
+import { validateAddress } from '../utils/validation.js'
+
+const { chainId, address } = parseEIP3770Address('sep:0x...')
+validateAddress(address) // throws if invalid
+```
+
+#### Storage
+All storage services follow the same pattern:
+```typescript
+import { ConfigStore } from '../storage/config-store.js'
+
+const store = new ConfigStore()
+store.set('key', value)
+const value = store.get('key')
+```
+
+### Testing Best Practices
+
+1. **Isolate test data** - Use temporary directories for test configs/data
+2. **Mock external dependencies** - Mock API calls and blockchain interactions
+3. **Test error cases** - Verify error handling and edge cases
+4. **Use factories** - Use test helpers from `src/tests/helpers/factories.ts`
+5. **Clean up after tests** - Remove temporary files/directories in `afterEach`
+
+### Environment Variables
+
+- `TEST_WALLET_PK` - Private key for E2E tests (Sepolia testnet)
+- `XDG_CONFIG_HOME` - Custom config directory
+- `XDG_DATA_HOME` - Custom data directory
+- `NODE_ENV` - Set to 'test' during testing
+- `CI` - Set to 'true' for non-interactive mode
+
+### Blockchain Testing
+
+E2E tests that interact with blockchain require:
+- A funded Sepolia test wallet
+- `TEST_WALLET_PK` environment variable set
+- Network access to Sepolia RPC and Safe API
+
+Get Sepolia ETH:
+- [Sepolia Faucet](https://sepoliafaucet.com/)
+- [Alchemy Sepolia Faucet](https://sepoliafaucet.com/)
+
+### Troubleshooting
+
+**Tests timing out:**
+- Increase timeout in test: `{ timeout: 60000 }`
+- Check network connectivity
+- Verify RPC endpoints are accessible
+
+**Interactive prompts in tests:**
+- Use `CLITestHelper.execWithInput()` for tests with prompts
+- Set `CI=true` environment variable for non-interactive mode
+- Consider adding `--yes` flags to commands
+
+**Storage conflicts:**
+- Use isolated directories with `XDG_CONFIG_HOME` and `XDG_DATA_HOME`
+- Clean up in `afterEach` hooks
+- Use `mkdtempSync()` for temporary directories
