## 2. 🔄 SMART CONTRACTS - DEPLOYED (Belum Verified)

### Contract Addresses (BSC Testnet)

#### KZD Token Contract
- **Address:** `0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802`
- **Status:** ✅ Deployed
- **Verified:** ❌ Not yet verified
- **Link:** https://testnet.bscscan.com/address/0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802

- **Status:** ✅ Deployed
- **Verified:** ❌ Not yet verified  
- **Link:** https://testnet.bscscan.com/address/0xd9706FEE1Ed7d788693357D72cBaBC71dB36F000

### Verification Status
- Hardhat verify command mengalami error (API issue)
- Contract sudah deployed dan berfungsi
- Verification bisa dilakukan manual via BSCScan

---

## 📝 CARA VERIFY CONTRACT MANUAL DI BSCSCAN

### Option 1: Via Hardhat (Retry nanti)

```bash
# Token Contract
npx hardhat verify --network bscTestnet 0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802

# Staking Contract (dengan constructor arg)
npx hardhat verify --network bscTestnet 0xd9706FEE1Ed7d788693357D72cBaBC71dB36F000 0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802
```

Jika masih error, gunakan Option 2.

---

### Option 2: Manual via BSCScan Website ⭐ RECOMMENDED

#### A. Verify Token Contract

1. **Buka link:** https://testnet.bscscan.com/address/0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802

2. **Klik tab "Contract"** → **"Verify and Publish"**

3. **Isi form:**
   - Contract Address: `0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802` (auto-filled)
   - Compiler Type: **Solidity (Single file)**
   - Compiler Version: **v0.8.20+commit.a1b79de6**
   - License Type: **MIT License**

4. **Klik "Continue"**

5. **Copy-paste source code:**
   - Buka file: `c:\xampp\htdocs\kuzastaking\contracts\KUZADESIGNToken.sol`
   - Copy semua isi file
   - Paste ke "Enter the Solidity Contract Code below"

6. **Optimization:** Pilih **No** (atau **Yes** dengan runs: 200 jika ada error)

7. **Constructor Arguments:** (Kosongkan - tidak ada constructor args)

8. **Klik "Verify and Publish"**

9. **Tunggu proses** → akan muncul success message ✅

---

#### B. Verify Staking Contract

1. **Buka link:** https://testnet.bscscan.com/address/0xd9706FEE1Ed7d788693357D72cBaBC71dB36F000

2. **Klik tab "Contract"** → **"Verify and Publish"**

3. **Isi form:**
   - Contract Address: `0xd9706FEE1Ed7d788693357D72cBaBC71dB36F000` (auto-filled)
   - Compiler Type: **Solidity (Single file)**
   - Compiler Version: **v0.8.20+commit.a1b79de6**
   - License Type: **MIT License**

4. **Klik "Continue"**

5. **Copy-paste source code:**
   - Buka file: `c:\xampp\htdocs\kuzastaking\contracts\KZDStaking.sol`
   - Copy semua isi file
   - Paste ke "Enter the Solidity Contract Code below"

6. **Optimization:** Pilih **No**

7. **Constructor Arguments (ABI-encoded):**
   ```
   0000000000000000000000007dffa9f69ac6676c478f004a3c6da9e7c5851802
   ```
   
   > Ini adalah token address dalam format ABI-encoded

8. **Alternative - use online ABI encoder:**
   - Buka: https://abi.hashex.org/
   - Function: constructor
   - Argument Type: `address`
   - Argument Value: `0x7dFfa9f69Ac6676c478f004a3c6dA9e7C5851802`
   - Copy hasil encoding
   - Paste ke Constructor Arguments

9. **Klik "Verify and Publish"**

10. **Tunggu proses** → akan muncul success message ✅

### ⚠️ CATATAN PENTING UNTUK VERIFICATION:

1. **Import statements:**
   - Jika ada error karena import `@openzeppelin/contracts`, Anda perlu:
   - Ganti dengan **Solidity (Multiple files)** atau **Standard JSON Input**
   - Atau copy-paste semua dependency contracts ke satu file

2. **Flattening Contract (Recommended):**
   ```bash
   npx hardhat flatten contracts/KUZADESIGNToken.sol > flattened-token.sol
   npx hardhat flatten contracts/KZDStaking.sol > flattened-staking.sol
   ```
   
   Lalu gunakan file flattened untuk verify.

3. **Compiler Settings:**
   - Pastikan gunakan compiler version yang sama: `0.8.20`
   - Optimization: Sesuaikan dengan hardhat.config.js

## 💡 APAKAH HARUS VERIFY?

### Tidak Wajib untuk Testing!
- ❌ Verification **TIDAK** diperlukan untuk testing di Testnet
- ✅ Contract sudah deployed dan **bisa digunakan sekarang**
- ✅ Frontend bisa connect ke contract tanpa verification
- ✅ Semua fungsi contract bisa dipanggil

### Keuntungan Verify (Optional):
- ✅ User bisa **read contract** di BSCScan
- ✅ Bisa **write contract** langsung di BSCScan  
- ✅ Source code **public** dan transparent
- ✅ Lebih **trusted** untuk production

### Rekomendasi:
- **Sekarang (Testing):** Skip verification, langsung test aplikasi
- **Nanti (Mainnet):** Wajib verify untuk kredibilitas

---

## 🎯 KESIMPULAN

### ✅ Yang Sudah Verified:
1. ✅ **MongoDB** - Service running & connection OK
2. ✅ **Smart Contracts** - Deployed & functional
3. ✅ **Environment** - Configured correctly
4. ✅ **Dependencies** - All installed

### ⏳ Yang Belum (Optional):
1. ⏳ **Contract Verification** di BSCScan (tidak blocking untuk testing)
2. ⏳ **Testing** full flow aplikasi

---

## 🚀 NEXT STEPS

### Pilihan 1: Skip Verification & Test Sekarang (Recommended)
```bash
npm run dev
```
Buka http://localhost:3000 dan test staking!

### Pilihan 2: Verify Dulu (Optional)
- Follow manual verification guide di atas
- Atau retry Hardhat command nanti
- Atau flatten contracts untuk easier verification

---

## 📞 Troubleshooting

### MongoDB tidak running?
```bash
net start MongoDB
```

### Hardhat verify masih error?
- Check BSCScan API key di `.env`
- Try manual verification via website
- Or flatten contracts and try again

---

**Status Final:**
- 🔥 System 100% ready untuk testing
- ✅ MongoDB OK
- ✅ Contracts deployed
- ⏳ Verification optional (bisa nanti)

**Next:** Start `npm run dev` dan test aplikasi! 🚀
