This file contains the Solidity Address library that provides functionalities related to Ethereum addresses. It includes functions to check if an address is a contract, send value to an address, make various types of function calls, and verify call results.

A library for Ethereum address-related operations.

isContract

isContract(address account) internal view returns (bool)

Checks if an address is a contract.

Errors

• Address: insufficient balance: Thrown if the contract does not have enough balance.
• Address: unable to send value, recipient may have reverted: Thrown if the transfer fails.

functionCall

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

Performs a function call to a target address with provided data.

Parameters

• target address: The target address of the function call.
• data bytes memory: The data to be sent with the function call.
