BitBasel implements enterprise-grade security measures to protect user assets, data, and transactions. Our security-first approach ensures safe trading of Bitcoin Ordinals and digital collectibles.

• No Private Key Storage - All private keys remain in user wallets
• No Server-Side Wallet Operations - Zero trust architecture
• Local Transaction Signing - All transactions signed locally
• Secure Memory Handling - Sensitive data cleared from memory

• HTTPS Enforcement - TLS 1.3 encryption for all communications
• Content Security Policy - Strict CSP headers prevent XSS
• CORS Configuration - Restricted cross-origin requests
• Rate Limiting - Protection against DDoS attacks

• Input Sanitization - All user inputs validated and sanitized
• SQL Injection Prevention - Parameterized queries only
• XSS Protection - Output encoding and CSP headers
• CSRF Protection - Token-based request validation

interface SecureWalletConnection {
  // Wallet never exposes private keys
  signMessage(message: string): Promise<string>;
  signTransaction(tx: BitcoinTransaction): Promise<SignedTransaction>;
  getPublicKey(): Promise<string>;
  getAddresses(): Promise<Address[]>;
}

// Security validation for all wallet operations
class WalletSecurityManager {
  validateSignature(message: string, signature: string, publicKey: string): boolean;
  verifyTransactionIntegrity(tx: SignedTransaction): boolean;
  checkAddressOwnership(address: string, signature: string): boolean;
}

• Unisat Wallet - Full security audit completed
• Xverse Wallet - Hardware wallet compatible
• Leather Wallet - Multi-signature support
• Hardware Wallets - Ledger, Trezor integration

interface SecureTransaction {
  // All transactions validated before processing
  validateInputs(): boolean;
  checkOutputs(): boolean;
  verifyFeeStructure(): boolean;
  confirmUserApproval(): boolean;
}

// Security checks before transaction broadcast
class TransactionSecurity {
  antiMEVProtection(tx: Transaction): boolean;
  dustAttackPrevention(outputs: Output[]): boolean;
  feeValidation(fee: number, txSize: number): boolean;
}

• Suspicious Activity Monitoring - Automated pattern recognition
• Failed Connection Attempts - Rate limiting and IP blocking
• Transaction Anomaly Detection - Unusual pattern alerts
• Wallet Compromise Indicators - Early warning system

class SecurityIncidentManager {
  // Automated response to security threats
  suspectWalletActivity(address: string): void;
  blockSuspiciousIP(ip: string): void;
  alertSecurityTeam(incident: SecurityIncident): void;
  quarantineTransaction(txId: string): void;
}
