Same start. Same end. Different wallet.

Scammers plant addresses in your transaction history that look just like ones you trust. Clone compares the address you’re about to use with the ones you’ve saved and tells you when the middle doesn’t match.

The scam works because wallets shorten addresses

This trick is called address poisoning. An attacker sends you a tiny transaction from an address built to match the first and last few characters of one you use. Later you copy it from your history, assume it’s right, and send your funds to the wrong place.

Wallets usually show only the ends of an address, so the difference in the middle never gets seen.

How Clone helps

  1. Save your trusted addressesAdd your own wallets and exchange deposit addresses with a label.
  2. Paste before you sendDrop in the full address you’re about to use.
  3. Read the resultYou get one of three answers.
Exact matchEvery character matches a saved address.
CloneThe ends match but the middle differs. The differing characters are marked in red.
New addressNothing like it is saved. Compare it fully and send a small test first.

Private by design

Clone runs in your browser. Your saved addresses stay on your device, and nothing is uploaded. There are no accounts and no wallet connections, and it never asks for a seed phrase.

What it can’t do
  • It can’t tell whether an address belongs to a scammer. It only spots clones of addresses you saved.
  • It checks format for Ethereum-style and Bitcoin addresses only, and doesn’t verify Ethereum checksums.
  • It isn’t a substitute for sending a small test amount first.
