Validate and generate EIP-55 checksummed Ethereum addresses.
EIP-55 Address Checksum Validator
Validate an Ethereum address and convert it to its EIP-55 checksummed format. The checksum uses Keccak-256 to determine which letters should be capitalized, catching typos before funds are lost.

EIP-55 introduces a checksum into Ethereum addresses by capitalizing certain letters based on the Keccak-256 hash of the lowercase address.
If the hash digit at position i is ≥ 8, the corresponding address character is capitalized.
