Smart contracts are integral to blockchain technology, but they can have vulnerabilities. Two common issues include reentrancy and overflow. Reentrancy happens when a contract's function is called recursively before its initial execution finishes, potentially leading to unauthorized access or theft. Overflow vulnerabilities occur when arithmetic operations exceed the maximum value that can be represented, causing unexpected behavior or security risks. Developers must be vigilant about these issues to ensure contract security.
