Common questions
What does a valid Bitcoin address result mean?
It means the address matches a supported Bitcoin encoding and passes its structural and checksum rules. It does not confirm ownership, balance, or transaction activity.
Can this decoder validate Bitcoin testnet addresses?
Yes. It recognizes supported Base58Check and Bech32 or Bech32m testnet prefixes and reports the detected network.
Can I paste a bitcoin: payment URI?
Yes. The decoder extracts the destination and BIP-321 payment instructions so the request can be inspected before use.
