Description

Build secure smart contracts avoiding common security vulnerabilities and pitfalls

Use Cases

  • Solidity contract development
  • Smart contract security audit
  • DeFi protocol development
  • NFT contract design
  • Contract upgrade strategies

Core Capabilities

  • Vulnerability Identification: Reentrancy attacks, overflow, etc.
  • Best Practices: OpenZeppelin standards
  • Gas Optimization: Reduce transaction costs
  • Test Coverage: Complete testing strategies

Example

// Please review this contract for security:
function withdraw(uint amount) public {
    require(balances[msg.sender] >= amount);
    (bool success, ) = msg.sender.call{value: amount}("");
    require(success);
    balances[msg.sender] -= amount;
}


// Please identify security issues and provide fixes

Notes

  • Smart contracts are hard to modify after deployment
  • Test thoroughly before deploying
  • Consider using proxy pattern
  • Get professional security audits
