I'm aware that the web3 library has the toCheckSumAddress method that converts an upper or lowercase Ethereum address to a checksum address. Am wondering if there is any method available that converts a checksummed address to a non-checksummed address (all lowercase)?

The reason I'm doing this is because a subgraph that I'm sending requests to only takes non-checksummed addresses. Thank you!

    .toLowerCase() should work

    As @MajdTL said, you just need to convert the string to all LowerCase. And that is it.
