Security & Private Key Management

Overview

RAZE takes user security seriously and implements multiple layers of protection to ensure your private keys and sensitive data remain secure. This document outlines our security architecture, data handling practices, and the measures we've implemented to protect your assets.

Security Architecture

Client-Side Security Model

RAZE operates on a client-side security model where:

• All private keys are stored and managed locally on your device

• No private keys are ever transmitted to our servers

• Transaction signing occurs entirely within your browser

• You maintain full custody and control of your assets

Hybrid Processing Approach

While private keys remain local, RAZE uses a hybrid approach for transaction processing:

• Frontend: Handles wallet management, private key storage, and transaction signing

• Backend: Provides transaction preparation, routing, and blockchain interaction services

• No Key Transmission: Private keys never leave your device during any operation

Private Key Management

Storage Methods

RAZE implements a multi-tier storage system for maximum reliability:

Primary Storage: IndexedDB

// Secure browser database storage
const DB_NAME = 'WalletDB';
const DB_VERSION = 1;
const WALLET_STORE = 'wallets';

Backup Storage: LocalStorage

• Automatic fallback if IndexedDB is unavailable

• Ensures wallet data persistence across browser sessions

• Encrypted using browser's built-in security mechanisms

Session Storage: Memory Only

• Active wallet sessions stored in browser memory

• Automatically cleared when browser is closed

• No persistent traces in temporary files

Private Key Format & Validation

RAZE uses industry-standard Solana private key formats:

// Base58 encoded private keys (64-88 characters)
const base58Pattern = /^[1-9A-HJ-NP-Za-km-z]{64,88}$/;

// Validation ensures proper key length (64 bytes for Solana)
if (privateKeyBytes.length !== 64) {
  return { wallet: null, error: 'Invalid private key length' };
}

Key Generation

New wallets are generated using cryptographically secure methods:

// Secure random key generation
const keypair = Keypair.generate();
const address = keypair.publicKey.toString();
const privateKey = bs58.encode(keypair.secretKey);

Data Protection Measures

Local Data Encryption

• Browser-Level Security: Leverages browser's built-in encryption for localStorage and IndexedDB

• Memory Protection: Sensitive data cleared from memory after use

• No Plaintext Storage: Private keys never stored in plaintext files

Network Security

HTTPS Enforcement

// Automatic HTTPS enforcement for production
if (urlObj.hostname !== 'localhost' && !/^(\d{1,3}\.){3}\d{1,3}$/.test(urlObj.hostname)) {
  urlObj.protocol = 'https:';
}

API Key Protection

• Server communications protected with API keys

• Keys stored locally and transmitted over encrypted connections

• No sensitive data in URL parameters or logs

Transaction Security

Local Signing Process

// All transaction signing happens locally
const signedTransaction = transaction.sign([keypair]);
// Only signed transactions are transmitted

Bundle Processing

• Transactions bundled for efficiency and privacy

• Multiple wallet operations grouped together

• Jito integration for MEV protection

Privacy Protection

Zero-Knowledge Architecture

RAZE implements a zero-knowledge approach:

• No Account Creation: No user accounts or registration required

• No Personal Data: No collection of personal information

• No Tracking: No user behavior tracking or analytics

• No Logs: Private keys and sensitive operations not logged

Data Minimization

We only process the minimum data required:

• Wallet Addresses: Only public addresses shared with backend

• Transaction Data: Only unsigned transaction templates processed

• No Private Keys: Never transmitted or stored server-side

Local-First Approach

All sensitive operations happen locally:

• Wallet generation and import

• Private key management

• Transaction signing

• Balance calculations

• Portfolio tracking

Security Best Practices

For Users

Wallet Management

• Backup Your Keys: Always backup private keys securely

• Multiple Copies: Store backups in multiple secure locations

• Offline Storage: Consider cold storage for large amounts

• Regular Audits: Periodically review your wallet list

Browser Security

• Keep Updated: Use latest browser versions

• Secure Environment: Use trusted devices and networks

• Clear Data: Clear browser data when using shared computers

• Extensions: Be cautious with browser extensions that can access page data

Operational Security

• Verify URLs: Always verify you're on the correct RAZE domain

• Check Transactions: Review all transaction details before signing

• Monitor Balances: Regularly check wallet balances for unauthorized activity

• Use Hardware Wallets: Consider hardware wallet integration for maximum security

For Developers

Code Security

• Input Validation: All user inputs validated and sanitized

• Error Handling: Secure error handling without information leakage

• Dependency Management: Regular security updates for all dependencies

• Code Reviews: All security-critical code reviewed by multiple developers

Technical Implementation

Wallet Creation Process

1. Key Generation: Cryptographically secure random key generation

2. Validation: Multiple validation checks on key format and length

3. Local Storage: Secure storage in IndexedDB with localStorage backup

4. Memory Management: Sensitive data cleared from memory after use

Transaction Flow

1. Preparation: Backend prepares unsigned transaction templates

2. Local Signing: All signing happens locally with user's private keys

3. Transmission: Only signed transactions transmitted to blockchain

4. Confirmation: Transaction status monitored and reported

Import/Export Security

// Secure file handling for bulk operations
const handleFileUpload = async (event: React.ChangeEvent<HTMLInputElement>) => {
  const file = event.target.files?.[0];
  // Validate file type and content
  // Process only valid private key formats
  // Clear file data from memory after processing
};

Security Incident Response

If You Suspect a Compromise

1. Immediate Actions:

   • Stop using the affected wallets immediately

   • Transfer funds to new, secure wallets

   • Clear browser data completely

2. Assessment:

   • Review recent transactions for unauthorized activity

   • Check all connected wallets

   • Verify the integrity of your backup files

3. Recovery:

   • Generate new wallets using secure methods

   • Update all stored private keys

   • Re-import only verified secure wallets
