4.3 Security: Multiple protection measures

Security is the lifeline of blockchain projects. DragonFly protects user assets and platform stability through multi-level protection measures. The following is a detailed security design: Third-party audit and code transparency The platform cooperates with the world's top blockchain security companies (such as CertiK, SlowMist, PeckShield) to conduct a comprehensive audit of all smart contracts to check for potential vulnerabilities (such as reentrancy attacks and overflow errors). The audit report will be public and users can access it at any time. In addition, the core contract code will be open source on GitHub and subject to community supervision. Multi-signature mechanism Key operations involving fund withdrawal or contract upgrades must be authorized by multiple signatures. For example, the platform sets up 5 management keys, and at least 3 signatures agree to perform the operation. This decentralized management reduces the risk of single point failure. Even if a key is leaked, it cannot threaten the security of the system alone. Cold wallet storage and fund isolation More than 90% of the platform's funds are stored in hardware cold wallets (such as Ledger or Trezor), which are physically isolated from the Internet. Hot wallets only retain a small amount of liquid funds (about 5%-10%) for daily withdrawal needs. Cold wallet fund withdrawals require multiple signatures and a strict internal approval process to ensure that hackers cannot directly attack core assets. Real-time monitoring and emergency response DragonFly has a 24/7 security monitoring team that uses AI tools to analyze abnormal activities on the chain (such as abnormally large transfers and a surge in contract call frequency). Once a potential threat is detected, the team will immediately initiate an emergency plan, such as suspending some functions, notifying users, or temporarily freezing suspicious accounts. In addition, the platform reserves an emergency insurance fund to compensate for user losses that may be caused by force majeure (such as hacker attacks).
