toChecksumAddress

The toChecksumAddress function is a utility method provided by the web3.utils module that takes an Ethereum address as a string and returns a checksum address. The function converts the input address to a checksum address, which is a modified version of the address that includes a checksum code at the end. The checksum code is calculated using the first 20 bytes of the address, and it helps to detect errors in the address, such as typos or incorrect formatting.

The toChecksumAddress function takes a single address argument, which can be an upper or lowercase Ethereum address.

The function returns a string representing the checksum address.

Here's an example of how the toChecksumAddress function can be used:

In this example, the toChecksumAddress function is called with an Ethereum address, and it returns a checksum address with the correct formatting and checksum code.
