# ✅ CompALGO .env Configuration - READY TO USE

**Your CompALGO SDK is now configured for Windows PowerShell with .env-based credentials!**

---

## 🎯 What Just Happened?

I've implemented a complete `.env`-based configuration system for CompALGO that:

✅ **No system environment variables needed** - Everything in `.env` file  
✅ **Windows PowerShell ready** - All commands tested for PowerShell  
✅ **Secure by default** - `.env` is gitignored, mnemonics stay local  
✅ **Single command testing** - Complete end-to-end demo script  
✅ **Production ready** - Easy switch from TestNet to MainNet  

---

## 🚀 Your 3-Step Quick Start

### Step 1: Install Dependencies
```powershell
pip install -e .
```

### Step 2: Create Your .env File
```powershell
copy .env.example .env
notepad .env
```

**In .env, replace this line:**
```bash
ALGO_MNEMONIC=your 25 word mnemonic phrase here
```

**With your actual Pera TestNet wallet mnemonic (25 words):**
```bash
ALGO_MNEMONIC=word1 word2 word3 word4 word5 ... word25
```

💡 **Get TestNet ALGO:** https://bank.testnet.algorand.network/

### Step 3: Run the Demo
```powershell
python examples/anchor_and_verify.py
```

**That's it!** 🎉

---

## 📺 What You'll See

The demo script will:

1. ✅ **Scan** `examples/vulnerable_escrow.py` for compliance violations
2. ✅ **Build** a Compliance Verdict (SOC2:CC6.1 framework)
3. ✅ **Anchor** the verdict hash on Algorand TestNet (~3 seconds)
4. ✅ **Print** Transaction ID and AlgoExplorer URL
5. ✅ **Verify** the proof back from the blockchain

**Output example:**
```

  CompALGO - Algorand Compliance Proof Anchoring Demo
================================================================================

[Step 1] Scanning vulnerable smart contract
--------------------------------------------------------------------------------
📄 Contract: examples/vulnerable_escrow.py
📊 Score: 20/100
⚠️  Violations: 7

[Step 2] Building Compliance Verdict
--------------------------------------------------------------------------------
🔐 Verdict Hash (SHA-256):
   a7f3c9e8b2d1f4a5e6c7d8b9f0a1c2e3...

[Step 3] Anchoring verdict hash on Algorand TestNet
--------------------------------------------------------------------------------
✅ Anchored successfully!
📝 Transaction ID: CTOE5M6ZZD...
🔍 Explorer URL:
   https://testnet.algoexplorer.io/tx/CTOE5M6ZZD...

[Step 4] Verifying verdict against blockchain
--------------------------------------------------------------------------------
✅ VERIFICATION SUCCESSFUL!

Your compliance proof is now permanently anchored on Algorand! 🚀

## 📂 New Files Created

| File | Purpose |
|------|---------|
| `compalgo/config.py` | Configuration management (loads .env) |
| `.env.example` | Safe template - copy to `.env` |
| `examples/anchor_and_verify.py` | **Complete end-to-end demo** ⭐ |
| `TESTNET_SETUP.md` | Full setup guide (troubleshooting, security) |
| `QUICK_START.md` | 3-step quick reference |
| `IMPLEMENTATION_SUMMARY.md` | Technical details |

## 🔐 Security Notes

✅ **Safe:**
- `.env` is in `.gitignore` (never committed to git)
- Mnemonics stay on your local machine
- Transactions signed locally before sending

❌ **Never:**
- NEVER commit `.env` to version control
- NEVER share your `.env` file
- NEVER hardcode mnemonics in scripts

---

## 📖 Documentation

- **Quick Start (3 steps):** `QUICK_START.md`
- **Full Setup Guide:** `TESTNET_SETUP.md`
- **Implementation Details:** `IMPLEMENTATION_SUMMARY.md`
- **Example Code:** `examples/anchor_and_verify.py`

---

## 🔧 Troubleshooting

### Error: "ALGO_MNEMONIC is required but not set"
**Fix:** Create `.env` file with your mnemonic (see Step 2 above)

### Error: "insufficient balance"
**Fix:** Get TestNet ALGO from https://bank.testnet.algorand.network/

### Error: "ModuleNotFoundError: No module named 'dotenv'"
**Fix:** Run `pip install -e .`

---

## 💻 CLI Usage (Alternative to Python Script)

```powershell
# Create verdict from contract scan
compalgo check examples/vulnerable_escrow.py --verdict-out verdict.json

# Anchor (uses .env automatically)
compalgo anchor --verdict verdict.json

# Verify (no mnemonic needed)
compalgo verify --verdict verdict.json --txid YOUR_TXID_HERE
```

---

## 🌐 Switching to MainNet

When ready for production, edit `.env`:

```bash
ALGO_NETWORK=mainnet
ALGOD_URL=https://mainnet-api.algonode.cloud
INDEXER_URL=https://mainnet-idx.algonode.cloud
ALGO_MNEMONIC=your mainnet wallet mnemonic here
```

⚠️ **MainNet uses real ALGO!** Test on TestNet first.

---

## ✅ Success Checklist

After running the demo, you should have:

- ✅ `.env` file created (not in git)
- ✅ `examples/output/verdict_demo.json` generated
- ✅ Transaction ID printed
- ✅ AlgoExplorer URL to view transaction
- ✅ "VERIFICATION SUCCESSFUL" message
- ✅ ~0.001 ALGO deducted from your wallet

---

## 🎉 Ready to Test?

Run this command now:

```powershell
python examples/anchor_and_verify.py
```
