Wallet Address Validator

Paste any Bitcoin or Ethereum/EVM address and get a real checksum verification - Base58Check, Bech32/Bech32m, or EIP-55, run entirely in your browser. Nothing is sent to a server.

Frequently asked questions

How does this validator work - is my address sent anywhere?

No. All validation runs client-side in your browser using standard cryptographic checks (double SHA-256 for Base58Check, Bech32/Bech32m for SegWit and Taproot, Keccak-256 for EIP-55). Your address is never transmitted to any server.

What's the difference between a valid format and a checksum match?

An all-lowercase or all-uppercase EVM address can still be a real, receivable address - it just isn't checksummed, so a typo wouldn't be caught by the format alone. A mixed-case EIP-55 address that matches its checksum has an extra layer of typo protection built in.

Does this confirm the address has funds or has been used?

No - this only verifies the address is structurally and cryptographically valid, meaning funds sent to it would be received. It does not check balance, transaction history, or ownership.
