About this Tool
Use this free Ethereum Address Validator to check whether an Ethereum address is formatted correctly. It can help detect missing 0x prefixes, invalid hexadecimal characters, wrong length, and malformed address strings. The validation runs directly in your browser and does not contact the blockchain, look up balances, or perform full EIP-55 checksum verification.
