Smart Contract Security is a critical aspect in the blockchain ecosystem. Below are some key points to consider when ensuring the security of your smart contracts.
Common Vulnerabilities:
- Reentrancy: Contracts that call external contracts may be vulnerable to reentrancy attacks.
- Integer Overflow/Underflow: Insecure arithmetic operations can lead to predictable vulnerabilities.
- DoS Attacks: Low gas limit can cause the contract to halt, effectively becoming a Denial of Service (DoS).
Best Practices:
- Always perform thorough testing on the contract before deploying.
- Consider using a library like OpenZeppelin, which includes numerous security audits.
