CASE 0001

Check before you connect.

Watchdog is a browser extension for Solana. The moment a site asks for your wallet, it runs three checks: what others say, whether the site looks fake, and what you're about to sign.

It watches. You sleep.

Move your lantern. Something is hiding in the dark.

Exhibit A

One wrong click is all it takes.

You connect to a new site every day. Scammers only need you to be wrong once, and a wallet gives you no second chance.

Look-alikes beat your eyes.

phantom.app or phantorn.app? Swap two letters for one and most people read the fake as the real thing.

Wallet pop-ups say too little.

The request you approve is a wall of code, or one word: Approve. That word can mean "spend all of this token, forever."

There is no undo.

A signed transaction is final. No bank to call, no chargeback, no support desk that can reverse it.

Fakes appear faster than blocklists.

A list only knows a scam after someone has lost money. Watchdog also reads the shape of the site, so it can bark at a fake nobody has reported yet.

Exhibit B

Fake sites look real. That's the whole trick.

Scammers copy a real site, change one letter in the address, and wait for you to hit Connect. One signature later, your wallet is empty. Watchdog sits at the door and asks the questions you don't have time to.

Exhibit C

Three checks. Before you connect.

Ask around

What do other people say about this site? Watchdog checks scam reports and community vouches. If nobody has looked at it yet, it tells you so and walks you through a quick check of your own.

Smell the site

Look-alike spelling, brand-new domains, address tricks. If the site is dressed up as something it isn't, Watchdog notices.

Read the fine print

Before you sign, Watchdog rewrites the request in plain words. “This lets the site move all your USDC” is a lot clearer than a wall of code.

Exhibit D: in-house algorithm

Built in-house to smell fakes.

The Nose is Watchdog's own detection algorithm. We wrote it for one job: spotting fake sites before you connect. It runs in your browser and never needs your wallet.

  1. It takes the address apart.Letter by letter: swapped characters, mixed alphabets, extra scam words, a real brand hiding in a subdomain.
  2. It weighs the evidence.Hard evidence means Barking. Softer signs add up to Sniffing. Every flag is listed with its reason.
  3. It keeps learning.Confirmed reports, community vouches and corrections become new scents, so copies of the same kit get caught faster.

    How Watchdog decides

    Watchdog's in-house algorithm, the Nose, decides with plain rules you can read. “Barking” if the site is reported, blocklisted or a close look-alike of a well-known site. “Sniffing” if there are two or more softer flags, like a brand-new domain, scam-style words or no reviews. Otherwise “Quiet”. Every flag is listed above, with its reason.
