+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+### Development
+- `yarn start` - Start the application in development mode using nodemon for auto-reloading
+- `yarn build` - Build the TypeScript code (creates /dist folder)
+- `yarn lint` - Run ESLint to check for code issues
+- `yarn lint:fix` - Run ESLint and automatically fix issues when possible
+
+### Testing
+- `yarn test` - Run all tests
+- `yarn test:watch` - Run tests in watch mode
+- `yarn test:coverage` - Run tests with coverage report
+- `yarn generate-test-ssl` - Generate self-signed SSL certificates for testing
+
+### Container
+- `yarn container:build` - Build the container image using Podman (optionally use --build-arg PORT=3080)
+
+## Architecture Overview
+
+Enclaved BitGo Express is a secure cryptocurrency signing server with two operational modes:
+
+### 1. Enclaved Express Mode (`APP_MODE=enclaved`)
+- Lightweight server focused solely on secure signing operations
+- Runs on port 3080 by default
+- Integrates with KMS for key management
+- Handles cryptographic operations securely
+- Exposes minimal endpoints focused on key generation and signing
+
+### 2. Master Express Mode (`APP_MODE=master-express`)
+- Full BitGo API functionality with integrated signing capabilities
+- Runs on port 3081 by default
+- Acts as an API gateway and communicates with Enclaved Express for signing operations
+- Provides a broader set of BitGo wallet operations and transaction handling
+
+### Security Architecture
+- Both modes support mutual TLS (mTLS) authentication
+- Certificates can be loaded from files or environment variables
+- Client certificate validation for secure communications
+- Option to validate client certificate fingerprints
+
+### Code Structure
+- `src/app.ts` - Main entry point that determines mode and starts the appropriate app
+- `src/enclavedApp.ts` - Enclaved Express mode implementation
+- `src/masterExpressApp.ts` - Master Express mode implementation
+- `src/initConfig.ts` - Configuration loading and validation
+- `src/routes/` - Express routes for both modes
+- `src/api/` - API implementation for both modes
+- `src/kms/` - KMS client and operations
+- `src/shared/` - Shared utilities and types
+
+### Configuration
+Configuration is managed through environment variables with defaults defined in `src/initConfig.ts`. The application requires specific environment variables depending on the mode:
+
+#### Common Variables
+- `APP_MODE` - Set to "enclaved" or "master-express"
+- `TLS_MODE` - Set to "mtls" or "disabled"
+- `BIND` - Address to bind to (default: localhost)
+- `TIMEOUT` - Request timeout in milliseconds (default: 305000)
+
+#### Enclaved Mode Specific
+- `ENCLAVED_EXPRESS_PORT` - Port to listen on (default: 3080)
+- `KMS_URL` - Required KMS service URL
+
+#### Master Express Mode Specific
+- `MASTER_EXPRESS_PORT` - Port to listen on (default: 3081)
+- `BITGO_ENV` - BitGo environment (default: test)
+- `ENCLAVED_EXPRESS_URL` - Required URL for the Enclaved Express server
+- `ENCLAVED_EXPRESS_CERT` - Required path to Enclaved Express certificate
+
+## API Endpoints
+
+### Enclaved Express (Port 3080)
+- `POST /ping` - Health check
+- `GET /version` - Version information
+- `POST /:coin/key/independent` - Generate independent keychain
+
+### Master Express (Port 3081)
+
+#### Health and Status Endpoints
+- `POST /ping` - Health check
+- `GET /version` - Version information
+- `POST /ping/enclavedExpress` - Test connection to Enclaved Express
+- `GET /version/enclavedExpress` - Get Enclaved Express version information
+
+#### Wallet Management
+- `POST /api/:coin/wallet/generate` - Generate wallet (supports onchain and TSS multisig types)
+
+#### Transaction Operations
+- `POST /api/:coin/wallet/:walletId/sendMany` - Send transaction with multiple recipients
+- `POST /api/:coin/wallet/:walletId/accelerate` - Accelerate pending transactions (CPFP/RBF)
+- `POST /api/:coin/wallet/:walletId/consolidate` - Consolidate wallet addresses
+- `POST /api/:coin/wallet/:walletId/consolidateunspents` - Consolidate unspent transaction outputs
+
+#### Recovery
+- `POST /api/:coin/wallet/recovery` - Recover wallet funds
