Security Design

Smart Contract Security Audit

Before writing smart contracts, conduct a comprehensive security audit and code review to ensure there are no potential vulnerabilities or security risks. Professional smart contract auditing firms or the community can assist in code review.

Permission Control

For smart contract functions involving critical operations, implement permission control mechanisms to ensure only authorized users can execute these operations, preventing malicious attacks.

Use of Secure Libraries

Utilize tested and certified security libraries, such as OpenZeppelin, to build smart contracts, avoiding reinventing the wheel and potential vulnerabilities.

Preventing Reentrancy Attacks

Implement design patterns to prevent reentrancy attacks, ensuring that the smart contract execution process cannot be repeatedly called, thereby preventing reentrancy attacks.

Secure Transmission

Use encryption techniques during data transmission to ensure user data and transaction information are not stolen or tampered with during transmission.

Decentralized Storage

For sensitive data, adopt decentralized storage solutions like IPFS to ensure data security and privacy.

Secure Interface Design

Design secure interfaces for external interactions to prevent malicious attacks and unauthorized access.

Regular Updates and Maintenance

Regularly update smart contracts and the system, addressing potential vulnerabilities and security issues to maintain system security.

Security Testing

Conduct comprehensive security testing, including functional, performance, and security testing, to ensure system stability and security.

Community Involvement

Encourage community participation and oversight, accept security suggestions and feedback from the community, and promptly address potential security issues.
