What this skill does
Solidity Security Master smart contract security best practices, vulnerability prevention, and secure Solidity development patterns. When to Use This Skill Writing secure smart contracts Auditing existing contracts for vulnerabilities Implementing secure DeFi protocols Preventing reentrancy, overflow, and access control issues Optimizing gas usage while maintaining security Preparing contracts for professional audits Understanding common attack vectors Critical Vulnerabilities 1. Reentrancy Attacker calls back into your contract before state is updated. Vulnerable Code: Secure Pattern (Checks-Effects-Interactions): Alternative: ReentrancyGuard 2. Integer Overflow/Underflow Vulnerable Code (Solidity < 0.8.0): Secure Pattern (Solidity >= 0.8.0): For Solidity < 0.8.0, use SafeMath: 3. Access Control Vulnerable Code: Secure Pattern: 4. Front-Running Vulnerable: Mitigation: Security Best Practices Checks-Effects-Interactions Pattern Pull Over Push Pattern Input Validation Emergency Stop (Circuit Breaker) Gas Optimization Use uint256 Instead of Smaller Types Pack Storage Variables Use calldata Instead of memory for Function Arguments Use Events for Data Storage (When Appropriate) Common Vulnerabilities Checklist Testing for Security Audit Preparation Resources references/reentrancy.md: Comprehensive reentrancy prevention references/access-control.md: Role-based access patterns references/overflow-underflow.md: SafeMath and integer safety references/gas-optimization.md: Gas saving techniques references/vulnerability-patterns.md: Common vulnerability catalog assets/solidity-contracts-templates.sol: Secure contract templates assets/security-checklist.md: Pre-audit checklist scripts/analyze-contract.sh: Static analysis tools Tools for Security Analysis Slither: Static analysis tool Mythril: Security analysis tool Echidna: Fuzzing tool Manticore: Symbolic execution Securify: Automated security scanner Common Pitfalls 1. …
