AltraditsAddress Check

Check a Bitcoin address

Paste any address. This page checks it on your device and shows what it pays to. Nothing leaves your browser, and it works with no internet.

How to compare safely
  • Compare the start, the middle and the end. Scam lookalikes match the first and last characters on purpose.
  • A valid checksum stops typos, not substitution. A scammer's address is valid too.
  • Malware can swap an address after you copy it. Compare what you pasted with the sender's original, character by character.
  • For a large payment, send a small test first and confirm it arrived.
What this cannot do
  • It cannot tell who owns an address. It shows what the address pays to, never whom.
  • It never needs a private key. If you pasted one by mistake, it says so and stops.
  • It shows the network, so a testnet address pasted by mistake stands out.
