# ✅ Environment Setup - Verification Complete
|
|
|
|
## 🎉 All Scripts Verified
|
|
|
|
All scripts have been verified to properly load environment variables from `.env` files.
|
|
|
|
---
|
|
|
|
## ✅ Scripts Checked
|
|
|
|
### 1. `src/strat/cli.ts` ✅
|
|
|
|
- ✅ Loads `dotenv` FIRST before any other imports
|
|
- ✅ Uses `getNetwork()` which lazy-loads RPC URLs from env vars
|
|
- ✅ Validates RPC URLs and shows helpful error messages
|
|
|
|
### 2. `src/cli/cli.ts` ✅
|
|
|
|
- ✅ Loads `dotenv` FIRST before any other imports
|
|
- ✅ Uses `process.env.PRIVATE_KEY` for transaction execution
|
|
- ✅ Uses RPC URLs from chain configs (which read from env)
|
|
|
|
### 3. `scripts/test-strategy.ts` ✅
|
|
|
|
- ✅ Loads `dotenv` FIRST before any other imports
|
|
- ✅ Reads `MAINNET_RPC_URL`, `TEST_SCENARIO`, `TEST_NETWORK` from env
|
|
- ✅ Validates RPC URL before proceeding
|
|
- ✅ Shows clear error messages if not configured
|
|
|
|
### 4. `scripts/check-env.ts` ✅
|
|
|
|
- ✅ Loads `dotenv` FIRST
|
|
- ✅ Verifies all RPC URLs are set and accessible
|
|
- ✅ Tests connections to each network
|
|
- ✅ Provides helpful feedback
|
|
|
|
### 5. `scripts/verify-setup.ts` ✅
|
|
|
|
- ✅ Loads `dotenv` FIRST
|
|
- ✅ Comprehensive verification of all setup components
|
|
- ✅ Checks scripts, configs, and scenarios
|
|
|

## ⚙️ Network Configuration
|
|
|
|
### `src/strat/config/networks.ts` ✅
|
|
|
|
- ✅ Lazy-loads RPC URLs when `getNetwork()` is called
|
|
- ✅ Ensures `dotenv` is loaded before reading env vars
|
|
- ✅ Supports network-specific env vars (e.g., `MAINNET_RPC_URL`)
|
|
- ✅ Falls back to defaults if not set
|
|
|
|
### `config/chains/*.ts` ✅
|
|
|
|
- ✅ Read `process.env` at module load time
|
|
- ✅ Since all entry points load `dotenv` FIRST, this works correctly
|
|
- ✅ Have sensible defaults as fallbacks
|

## 📋 Environment Variables
|
|
|
|
### Required
|
|
|
|
| Variable | Description | Status |
|
|
|----------|-------------|--------|
|
|
| `MAINNET_RPC_URL` | For mainnet fork testing (required for most scenarios) | ✅ |
|
|
|
|
### Optional
|
|
|
|
| Variable | Description | When Needed |
|
|
|----------|-------------|-------------|
|
|
| `BASE_RPC_URL` | For Base network testing | Multi-chain testing |
|
|
| `ARBITRUM_RPC_URL` | For Arbitrum testing | Multi-chain testing |
|
|
| `OPTIMISM_RPC_URL` | For Optimism testing | Multi-chain testing |
|
|
| `POLYGON_RPC_URL` | For Polygon testing | Multi-chain testing |
|
|
| `PRIVATE_KEY` | Only needed for mainnet execution (not fork testing) | Mainnet execution |
|
|
| `TEST_SCENARIO` | Override default test scenario | Custom scenarios |
|
|

## ✅ Validation
|
|
|
|
All scripts now include:
|
|
|
|
- ✅ RPC URL validation (checks for placeholders)
|
|
- ✅ Clear error messages if not configured
|
|
- ✅ Helpful suggestions (e.g., "Run 'pnpm run check:env'")
|
|
- ✅ Fallback to defaults where appropriate

## 🧪 Testing
|
|
|
|
Run these commands to verify your setup:
|
|
|
|
```bash
|
|
# 1. Check environment variables
|
|
pnpm run check:env
|
|
|
|
# 2. Verify complete setup
|
|
pnpm run verify:setup
|
|
|
|
# 3. Test with a scenario (requires valid RPC URL)
|
|
pnpm run strat:test
|
|
```
|

## 🔧 How It Works
|
|
|
|
### 1. Entry Point (CLI script or test script)
|
|
|
|
- 📥 Loads `dotenv.config()` FIRST
|
|
- 📄 This reads `.env` file into `process.env`
|
|
|
|
### 2. Network Configuration
|
|
|
|
- 🔗 `getNetwork()` is called
|
|
- ⚡ Lazy-loads RPC URLs from `process.env`
|
|
- ✅ Returns network config with RPC URL
|
|
|
|
### 3. Fork Orchestrator
|
|
|
|
- 🔌 Uses the RPC URL from network config
|
|
- 🌐 Connects to the RPC endpoint
|
|
- 🍴 Creates fork if needed
|
|
|
|
### 4. Validation
|
|
|
|
- ✅ Scripts validate RPC URLs before use
|
|
- 🔍 Check for placeholders like "YOUR_KEY"
|
|
- 💬 Show helpful error messages if invalid
|
|

## 🔧 Troubleshooting
|
|
|
|
If environment variables aren't loading:
|
|
|
|
### 1. Check .env file exists
|
|
|
|
```bash
|
|
ls -la .env
|
|
```
|
|
|
|
### 2. Verify dotenv is loaded first
|
|
|
|
- ✅ Check that `import dotenv from 'dotenv'` and `dotenv.config()` are at the top
|
|
- ✅ Before any other imports that use `process.env`
|
|
|
|
### 3. Test environment loading
|
|
|
|
```bash
|
|
node -e "require('dotenv').config(); console.log(process.env.MAINNET_RPC_URL)"
|
|
```
|
|
|
|
### 4. Run verification
|
|
|
|
```bash
|
|
pnpm run verify:setup
|
|
```
|
|

|
## 💡 Best Practices
|
|
|
|
### 1. Always load dotenv first
|
|
|
|
```typescript
|
|
// ✅ Good
|
|
import dotenv from 'dotenv';
|
|
dotenv.config();
|
|
import { other } from './other.js';
|
|
```
|
|
|
|
### 2. Use lazy-loading for configs
|
|
|
|
```typescript
|
|
// ✅ Good - lazy load
|
|
function getNetwork() {
|
|
return { rpcUrl: process.env.MAINNET_RPC_URL || 'default' };
|
|
}
|
|
```
|
|
|
|
### 3. Validate before use
|
|
|
|
```typescript
|
|
// ✅ Good - validate
|
|
if (!rpcUrl || rpcUrl.includes('YOUR_KEY')) {
|
|
throw new Error('RPC URL not configured');
|
|
}
|
|
```
|
