Address.sol

This is a solidity library for common address operations. It provides functions to check if an address is a contract, send value to an address, and perform function calls with various conditions. The functions employ low-level operations and handle error conditions, making them safer for use in smart contracts.

Address

A solidity library providing common operations for addresses.

isContract

isContract(address account) internal view returns (bool)

Checks if an address is a contract.

Parameters

• account address: The address to check.

Return Values

• bool: True if the address is a contract, false otherwise.

sendValue

sendValue(address payable recipient, uint256 amount) internal

Sends a specified amount of wei to a recipient address.

Parameters

• recipient address payable: The recipient address.
• amount uint256: The amount of wei to send.

functionCall

functionCall(address target, bytes memory data) internal returns (bytes memory)

Performs a function call on a target address with specified data.

Parameters

• target address: The target address.
• data bytes memory: The function call data.

Return Values

• bytes memory: The raw returned data.

Examples

Using the Address library

This example demonstrates how to use the Address library to perform common address operations.

// Import the Address library
import './Address.sol';

// Use the Address library
function testAddress() public {
    address account = msg.sender;
    bool isContract = Address.isContract(account);
    if (!isContract) {
        Address.sendValue(account, 1 ether);
    }
    bytes memory data = '';
    Address.functionCall(account, data);
}
