Common Vulnerabilities in Smart Contracts

Smart contracts, like any software, can have weaknesses that attackers might exploit. Understanding these vulnerabilities is crucial for developers and users alike.

Reentrancy Attacks

Reentrancy attacks happen when a malicious contract calls a function in another contract before the first call finishes. This can allow the attacker to drain funds from the contract. To prevent this, developers should use checks to ensure that a function cannot be called again until it has completed.

Integer Overflow and Underflow

Smart contracts that perform math operations without proper checks can face integer overflow or underflow.
