Ethereum Address Validator checks whether a pasted value looks like a valid Ethereum address and whether its mixed-case EIP-55 checksum is correct. It is useful before copying addresses into docs, support tickets, test fixtures, CSV imports, or wallet workflows.
The tool verifies the 0x prefix, 40 hexadecimal characters, invalid characters, lowercase or mixed-case style, and EIP-55 checksum when checksum protection is present or required.
Address format validation is not an ownership check. It also does not prove whether the address has balance, transactions, or contract bytecode because that requires a blockchain lookup.
Mixed-case Ethereum addresses should match EIP-55 exactly. Lowercase addresses can be structurally valid, but they do not help catch accidental character changes. For production payment flows, validate the format here, then verify the address in the wallet or application that will send funds.
No. A valid format only means the string can be an Ethereum address. Always confirm the recipient and network before sending assets.
EIP-55 uses uppercase and lowercase letters as a checksum. If one character is changed, a mixed-case address often fails validation.
Lowercase addresses can be structurally valid, but they do not carry EIP-55 typo protection. Use checksummed addresses when possible.
No. Validation and checksum calculation run in your browser. Opening the explorer link is the only action that leaves the page.
