Contract Functions

Helpers

A library of reusable helper functions for various common Solidity tasks.

Version 0.3.4

Helpers Contract

This contract provides a collection of helper functions that can be used in other smart contracts. These functions cover tasks such as address validation, safe math operations, and data manipulation.

Features

  • **Address Validation:** Helper functions to validate Ethereum addresses and ensure they are valid.
  • **Safe Math:** Functions for performing arithmetic operations safely, preventing overflows and underflows.
  • **Data Manipulation:** Functions to work with bytes arrays, strings, and other data types efficiently.
  • **String Utilities:** Functions for string manipulation, such as splitting and joining strings.
  • **Time and Block Operations:** Functions for obtaining current block timestamps and block numbers.

    • Usage

    To use the helper functions, simply import the Helpers contract into your own smart contract and call the desired functions.

    Examples

    Here's an example of how to use the address validation helper function:

    // Import the Helpers contract import "./Helpers.sol"; // ... your contract code ... function myFunction(address _address) public { // Validate the address using the helper function require(Helpers.isValidAddress(_address), "Invalid address provided"); // ... rest of your function logic ... }

    Implementation Details

    The Helpers contract implements each helper function using best practices for security and efficiency.

    Best Practices

  • Always use the helper functions provided by the Helpers contract for common tasks.
  • Ensure you understand the functionality of each helper function before using it.
  • Review the code of the Helpers contract for any potential vulnerabilities before integrating it into your project.
