Pocket Universe

Step 1 of 5

Know before you sign

We check every transaction before you sign, and show you what it really does.

  • See exactly what leaves your wallet
  • Get a clear warning if it’s a scam
  • Covered up to $30,000 if we miss one.

Step 2 of 5

We warn you in time

Some dangers can’t be spotted when you sign. The problem may be your own wallet, or a site that was safe this morning.

So we warn you in your browser, the moment we know.

  • $116M lost to a Coldcard wallet flaw, in five days
  • $1.2M stolen from the hijacked CoW Swap site, in under five hours

People warned early still had time to act.

Step 3 of 5

Paste the right address

Scammers go after the address you copy. One wrong address, and the money is gone for good.

  • Address poisoning: a look-alike address planted in your history, so you copy the wrong one
  • Clipboard hijacking: malware swaps the address while it sits in your clipboard

We check every address you copy or paste, before you send.

Step 4 of 5

We spot fake accounts on X

Giveaway scams copy a real account’s picture and name, then reply under its posts.

  • We compare the picture, the name and the handle with the real account
  • A likely fake is marked right under the post, before you click
  • One hover shows you the real account

Step 5 of 5

Set your security level

Choose what to turn on. It takes a few seconds, and doing it now means we won’t have to stop you mid‑transaction to ask.

Safe to sign
Pocket Universe popup for a swap on the real app.uniswap.org: verified contract and domain, nothing suspicious, covered up to $30,000.
We stop this
Pocket Universe popup for the fake uniswop.gg: about $24,000 in tokens would leave and nothing comes back. The site is blocked as malicious and the transaction is not covered.
