Frequently Asked Questions

Find Quick Answers

What Bitcoin address types does this tool support?

The tool supports Legacy P2PKH (starting with '1'), P2SH (starting with '3'), Native SegWit Bech32 (starting with 'bc1q'), and Taproot (starting with 'bc1p') addresses for both mainnet and testnet networks.

How does the validation work?

Validation uses regex patterns to check the address prefix and length, followed by a Base58 or Bech32 checksum verification depending on the address type. The tool also validates the network (mainnet/testnet) based on the prefix.

Can I validate multiple addresses at once?

No, this tool validates one Bitcoin address at a time for clarity and accuracy. You can clear the input and validate another address sequentially.

Is this tool safe to use with my Bitcoin addresses?

Yes, all validation happens entirely in your browser (client-side). No addresses are sent to any server, ensuring complete privacy and security.
