Require Should Used Instead of Assert

• Severity: Low

• Confidence: High

Description

Solidity has two error handling functions: require() and assert(). require() is used for validating user input and other conditions that must be met for the code to execute successfully. When a require() statement fails, the transaction is reverted and gas is consumed. assert() is used for checking internal errors in the code, and when it fails, all gas is consumed and the transaction is reverted. However, assert() is discouraged as it can cause serious problems, such as wasted gas and denial of service attacks. Therefore, it's recommended to use require() instead of assert() in most cases.
