The checkAddressCheckSum function is a callable function in the web3-utils library that checks the checksum of a given address. The function takes a string parameter data representing the address, and returns a boolean value indicating whether the checksum is valid or not.
Here's an example of how to use the checkAddressCheckSum function:
The function first converts the address to a byte array, and then calculates the checksum using the Keccak-256 hash function. The checksum is then compared to the last 4 bytes of the address to verify its validity. If the checksum matches, the function returns true, otherwise it returns false.
Note that this function is deprecated and will be removed in a future release. It is recommended to use the web3-validator package instead for address validation.
Parameters
data: string - The address to be checked.
boolean - true if the checksum is valid, false otherwise.
