# Security & Best Practices

### Platform Security

#### Cold Storage

* **95% of funds** stored in cold wallets (offline)
* Multi-signature wallets requiring 3-of-5 keys
* Geographic distribution of keys
* Regular security audits

#### Hot Wallet Protection

* Only 5% of funds in hot wallets for liquidity
* Real-time monitoring and anomaly detection
* Automatic withdrawal limits
* Instant freeze mechanisms

#### Infrastructure Security

* **Encryption:** AES-256 for data at rest, TLS 1.3 for data in transit
* **DDoS Protection:** Enterprise-grade mitigation
* **Penetration Testing:** Quarterly third-party audits
* **Bug Bounty Program:** Up to $100,000 rewards

### Account Security

#### Two-Factor Authentication (2FA)

**Strongly Recommended for All Users**

**Setting Up 2FA**

1. Go to **Settings → Security → Two-Factor Authentication**
2. Download an authenticator app:
   * Google Authenticator
   * Authy
   * Microsoft Authenticator
3. Scan QR code with your app
4. Enter 6-digit code to confirm
5. **Save backup codes** in a secure location

**2FA Best Practices**

✅ **DO:**

* Use authenticator apps (not SMS)
* Store backup codes offline
* Enable 2FA on email account
* Use different 2FA for each service

❌ **DON'T:**

* Use SMS-based 2FA (vulnerable to SIM swapping)
* Share 2FA codes with anyone
* Store backup codes digitally without encryption

#### Strong Passwords

**Requirements:**

* Minimum 12 characters
* Mix of uppercase, lowercase, numbers, symbols
* Unique to VEXAR (no reuse)

**Use a Password Manager:**

* 1Password
* Bitwarden
* LastPass
* KeePassXC

**Example Strong Password:**

```
Vx$9mK2#pL8@qR5n
```

#### Anti-Phishing Code

Set a custom code that appears in all genuine VEXAR emails.

**Setup:**

1. Settings → Security → Anti-Phishing Code
2. Enter a unique phrase (e.g., "BlueWhale2025")
3. Verify in all future emails from VEXAR

**Red Flag:** Email from "VEXAR" without your code = SCAM

### Withdrawal Security

#### Whitelist Addresses

Only allow withdrawals to pre-approved addresses.

**How to Enable:**

1. Settings → Security → Withdrawal Whitelist
2. Add trusted addresses
3. 24-hour waiting period before first use

**Benefits:**

* Protection against account compromise
* Peace of mind even if password is stolen

#### Withdrawal Confirmations

All withdrawals require:

* Email confirmation
* 2FA code
* Optional: SMS confirmation

**Processing Time:**

* Manual review for large withdrawals (>$50,000)
* 1-hour security hold for first-time addresses

### API Security

#### API Key Management

**Create Separate Keys for Each Purpose:**

* Read-only keys for monitoring
* Trade-only keys for bots (no withdrawal permission)
* Full access keys (use sparingly)

**Key Restrictions:**

* IP whitelist: Limit access to specific IPs
* Permission levels: Grant minimum required access
* Expiration dates: Set automatic key expiry

#### API Key Storage

✅ **DO:**

* Store in environment variables
* Use secrets management (AWS Secrets Manager, HashiCorp Vault)
* Encrypt keys at rest

❌ **DON'T:**

* Hardcode in source code
* Commit to GitHub
* Share via email/chat

**Example (Environment Variables):**

```bash
export VEXAR_API_KEY="your_key_here"
export VEXAR_API_SECRET="your_secret_here"
```

#### Rotating API Keys

Change API keys regularly:

* **Minimum:** Every 90 days
* **Best Practice:** Every 30 days
* **Immediately:** If potentially compromised

### Common Threats

#### Phishing Attacks

**Warning Signs:**

* Emails asking for passwords/2FA codes
* Suspicious sender addresses (<vexar.support@gmail.com> ❌)
* Urgent language ("Account suspended! Act now!")
* Links to fake login pages

**Legitimate VEXAR Domains:**

* ✅ <https://vexatrade.com>
* ✅ app.<https://vexatrade.com>
* ✅ api.vexatrade.com
* ❌ vexar-trade.com (FAKE)
* ❌ vexar.net (FAKE)

**If Unsure:**

* Type <https://vexatrade.com> directly into browser
* Check SSL certificate
* Contact support through official channels

#### Social Engineering

**Common Tactics:**

* Impersonating VEXAR support
* Fake "account verification" calls
* "Investment opportunities" from "VEXAR partners"
* Tech support scams

**Remember:**

* VEXAR will NEVER ask for your password
* VEXAR will NEVER ask for 2FA codes
* VEXAR will NEVER ask you to send crypto for "verification"

#### Malware & Keyloggers

**Protection:**

* Keep operating system updated
* Use reputable antivirus software
* Don't download suspicious files
* Avoid trading on public Wi-Fi
* Use hardware wallets for long-term storage

#### SIM Swapping

Attackers hijack your phone number to bypass SMS 2FA.

**Prevention:**

* Use authenticator apps (not SMS)
* Set up carrier PIN/password
* Use Google Voice or similar for account recovery

### Insurance & Protection

#### VEXAR Insurance Fund

* $50 million reserve fund
* Covers platform failures (not user error)
* Annual third-party audits

#### What's Covered

✅ **Covered:**

* Exchange security breaches
* Hot wallet compromises
* Platform technical failures

❌ **NOT Covered:**
