Ethereum Address Validator
Ethereum addresses are 20-byte hex strings prefixed with 0x. EIP-55 defines a mixed-case checksum encoding: if the i-th hex digit of the keccak256 hash of the lowercase address is ≥ 8, the i-th character of the address is uppercased. This allows detecting single-character typos in addresses. Lowercase or uppercase-only addresses are valid but have no checksum protection.
