# ✅ Environment Setup Verification - Complete

## 🎉 Verification Results

All scripts have been verified to properly connect to `.env` files and handle secrets correctly.

---

## ✅ Scripts Verified

### 1. `src/strat/cli.ts` ✅

- ✅ Loads `dotenv` FIRST (line 14-15)
- ✅ Before any other imports
- ✅ Validates RPC URLs before use
- ✅ Shows helpful error messages

### 2. `src/cli/cli.ts` ✅

- ✅ Loads `dotenv` FIRST (line 13-15)
- ✅ Before any other imports
- ✅ Uses `PRIVATE_KEY` from env for execution
- ✅ Validates private key before use

### 3. `scripts/test-strategy.ts` ✅

- ✅ Loads `dotenv` FIRST (line 18-19)
- ✅ Before any other imports
- ✅ Reads `MAINNET_RPC_URL`, `TEST_SCENARIO`, `TEST_NETWORK`
- ✅ Validates RPC URL with placeholder checks
- ✅ Shows clear error messages

### 4. `scripts/check-env.ts` ✅

- ✅ Loads `dotenv` FIRST
- ✅ Tests all RPC URL connections
- ✅ Validates environment setup
- ✅ Provides detailed feedback

### 5. `scripts/verify-setup.ts` ✅

- ✅ Loads `dotenv` FIRST
- ✅ Comprehensive setup verification
- ✅ Checks all components

---

## ✅ Configuration Verified

### 1. `src/strat/config/networks.ts` ✅

- ✅ Lazy-loads RPC URLs when `getNetwork()` is called
- ✅ Ensures `dotenv` is loaded before reading env vars
- ✅ Supports all network-specific env vars
- ✅ Has sensible fallbacks

### 2. `config/chains/*.ts` ✅

- ✅ Read `process.env` at module load
- ✅ Work correctly because entry points load dotenv first
- ✅ Have default fallbacks

## 📋 Environment Variables

### Required

| Variable | Description | Status |
|----------|-------------|--------|
| `MAINNET_RPC_URL` | Required for mainnet fork testing | ✅ |

### Optional

| Variable | Description | When Needed |
|----------|-------------|-------------|
| `BASE_RPC_URL` | Base network RPC endpoint | Multi-chain testing |
| `ARBITRUM_RPC_URL` | Arbitrum One RPC endpoint | Multi-chain testing |
| `OPTIMISM_RPC_URL` | Optimism network RPC endpoint | Multi-chain testing |
| `POLYGON_RPC_URL` | Polygon network RPC endpoint | Multi-chain testing |
| `PRIVATE_KEY` | Private key for executing transactions | Mainnet/testnet execution only |
| `TEST_SCENARIO` | Override default test scenario path | Custom test scenarios |
| `TEST_NETWORK` | Override default test network | Multi-chain testing |

---

## ✅ Validation Features

All scripts include:

- ✅ RPC URL validation (checks for placeholders like "YOUR_KEY")
- ✅ Clear error messages if not configured
- ✅ Helpful suggestions (e.g., "Run 'pnpm run check:env'")
- ✅ Fallback to defaults where appropriate

---

## 🔧 Verification Commands

```bash
# Check environment variables and RPC connections
pnpm run check:env

# Verify complete setup
pnpm run verify:setup

# Test with a scenario
pnpm run strat:test
```

---

## 🔐 Security

| Check | Status | Description |
|-------|--------|-------------|
| `.env` in `.gitignore` | ✅ | `.env` file is in `.gitignore` |
| `.env.example` template | ✅ | `.env.example` provides template |
| Private keys protection | ✅ | Private keys only used when explicitly needed |
| RPC URL validation | ✅ | RPC URLs validated before use |
| No hardcoded secrets | ✅ | No hardcoded secrets |

---

## 🧪 Test Results

Running `pnpm run verify:setup` shows:

- ✅ All scripts load dotenv correctly
- ✅ Network config loads correctly
- ✅ Scenario files exist
- ✅ Environment variables are accessible

---

## 🎉 Conclusion

All scripts are properly connected to `.env` files and handle secrets correctly. The setup is complete and ready for use!
