# USDT Treasury Multisig Yapısı
|
||||||
|
|
||||||
|
## Genel Bakış
|
||||||
|
|
||||||
|
USDT Treasury, kullanıcıların gerçek USDT'yi chain'de wUSDT olarak kullanabilmesi için 1:1 backing ile çalışan merkezi bir hazinedir. Güvenlik ve şeffaflık için 3/5 multisig yapısı kullanılır.

| # | Rol | Tiki | Unique | AccountId | Sorumluluk |
|
||||||
|
|---|-----|------|--------|-----------|------------|

### Açıklama:
|
||||||
|
- **Unique Roller (3):** Chain'de sadece 1 kişi bu role sahip olabilir (blockchain garantili)
|
||||||
|
- **Non-Unique Roller (2):** Spesifik, güvenilir kişiler seçilmiştir
|
||||||
|
- **Threshold:** Her işlem için 5 kişiden 3'ünün onayı gereklidir
|
||||||
|
|

|
|
||||||
|
## 🔐 Güvenlik Katmanları
|
||||||
|
|
||||||
|
### 1. Multi-Signature (3/5)
|
||||||
|
- Tek kişi fonları kontrol edemez
|
||||||
|
- Minimum 3 kişinin onayı gereklidir
|
||||||
|
- Gnosis Safe üzerinde şeffaf
|
||||||
|
|
||||||
|
### 2. Tiered Withdrawal Limits
|
||||||
|
| Miktar | Bekleme Süresi | Gerekli İmza | Not |
|
||||||
|
|--------|----------------|--------------|-----|
|
||||||
|
| < $1,000 | Anında | 3/5 | Küçük işlemler |
|
||||||
|
| $1,000 - $10,000 | 1 saat | 3/5 | Orta işlemler |
|
||||||
|
| > $10,000 | 24 saat | 3/5 | Büyük işlemler - community alert |
|
||||||
|
|
||||||
|
### 3. On-Chain Proof of Reserves
|
||||||
|
- Her saat otomatik kontrol
|
||||||
|
- Total wUSDT supply = Ethereum'daki USDT balance
|
||||||
|
- Public dashboard: `https://pezkuwi.com/reserves`
|
||||||
|
|
||||||
|
### 4. Insurance Fund
|
||||||
|
- Swap fee'lerden %10 ayrılır
|
||||||
|
- Hedef: Total supply'ın %20'si
|
||||||
|
- Hack/loss durumunda kullanıcıları korur
|
||||||

## 📊 İşlem Akışı
|
||||||
|
|
||||||
|
### Deposit (USDT → wUSDT)
|
||||||
|
```
|
||||||
|
1. Kullanıcı Ethereum'da USDT gönderir
|
||||||
|
→ Multisig Address: 0x123...
|
||||||
|
|
||||||
|
2. Noter işlemi kaydeder
|
||||||
|
→ Transaction hash, miktar, user address
|
||||||
|
|
||||||
|
3. Berdevk public dashboard'u günceller
|
||||||
|
→ Şeffaflık için
|
||||||
|
|
||||||
|
4. 3/5 multisig onayı ile wUSDT mint edilir
|
||||||
|
→ User Pezkuwi chain'de wUSDT alır
|
||||||
|
|
||||||
|
5. Reserves kontrol edilir
|
||||||
|
→ wUSDT supply ≤ USDT balance
|
||||||
|
```
|
||||||
|
|
||||||
|
### Withdrawal (wUSDT → USDT)
|
||||||
|
```
|
||||||
|
1. Kullanıcı chain'de wUSDT burn eder
|
||||||
|
→ Ethereum address belirtir
|
||||||
|
|
||||||
|
2. 24 saat bekleme (>$10K için)
|
||||||
|
→ Güvenlik önlemi
|
||||||
|
|
||||||
|
3. Noter withdrawal request kaydeder
|
||||||
|
→ Blockchain'de doğrulanabilir
|
||||||
|
|
||||||
|
4. 3/5 multisig onayı ile USDT gönderilir
|
||||||
|
→ Ethereum'da kullanıcıya
|
||||||
|
|
||||||
|
5. Berdevk işlemi duyurur
|
||||||
|
→ Public dashboard + Twitter/Discord
|
||||||
|
```
|
||||||
|

|
|
||||||
|

|
# https://app.safe.global adresine git
|
||||||
|
1. "Create New Safe" tıkla
|
||||||
|
2. Ethereum Mainnet seç
|
||||||
|
3. 5 owner ekle (yukarıdaki adresler)
|
||||||
|
4. Threshold: 3/5
|
||||||
|
5. Deploy
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. USDT Deposit
|
||||||
|

|
||||||
|
# İlk likidite (örnek: $10,000)
|
||||||
|
1. Gnosis Safe address'e USDT gönder
|
||||||
|
2. Etherscan'de doğrula
|
||||||
|
3. Safe balance = $10,000 USDT
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Chain'de wUSDT Asset Oluştur
|
||||||
|
```bash
|
||||||
|
# Polkadot.js Apps ile
|
||||||
|
1. Developer → Sudo → assets.create
|
||||||
|
- id: 2
|
||||||
|
- admin: <multisig_pezkuwi_address>
|
||||||
|
- min_balance: 1000000
|
||||||
|
|
||||||
|
2. Developer → Sudo → assets.setMetadata
|
||||||
|
- id: 2
|
||||||
|
- name: "Wrapped USDT"
|
||||||
|
- symbol: "wUSDT"
|
||||||
|
- decimals: 6
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Pool Oluştur
|
||||||
|
```bash
|
||||||
|
# wUSDT/PEZ ve wUSDT/wHEZ poolları
|
||||||
|

|
||||||
|
npm run deploy
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## ⚠️ Risk Yönetimi
|
||||||
|
|
||||||
|
### Potansiyel Riskler
|
||||||
|
1. **Multisig Key Loss:** 2/5 key kaybolsa bile 3/5 hala çalışır
|
||||||
|
2. **Ethereum Gas Fees:** High gas durumunda withdrawaller pahalı
|
||||||
|
3. **Smart Contract Bug:** Gnosis Safe audited ama risk var
|
||||||
|
4. **Regulatory:** USDT yasal sorunlar yaşayabilir
|
||||||
|
|
||||||
|
### Mitigations
|
||||||
|
1. ✅ Key backup stratejisi (her owner için)
|
||||||
|
2. ✅ Gas limit alarms (yüksek gas'da uyar)
|
||||||
|
3. ✅ Insurance fund (bug durumunda)
|
||||||
|
4. ✅ Legal counsel (compliance için)
