Smart contracts, self-executing code on blockchains, are prone to vulnerabilities like reentrancy, integer overflow/underflow, and unauthorized access. Reentrancy attacks exploit recursive calls to drain funds, as seen in the DAO hack. Integer issues arise from improper arithmetic handling, risking unexpected behavior. Access control flaws allow unauthorized function execution. Audit methods include static analysis, using tools like Mythril to detect code flaws, and dynamic testing, simulating attacks via fuzzing. Manual code reviews by experts ensure logic integrity. Formal verification mathematically proves correctness. Regular audits, secure coding practices, and bug bounties enhance smart contract security.
