CapyGuard

What CapyGuard does

Three layers of calm, quiet protection between you and the scammers.

Scam site blocking

Stopped before loading

Dangerous sites never open. You get a calm capybara warning instead.

107,000+ known scams

Daily-updated public scam lists, plus sites you report yourself.

4,600+ real projects

Maintained lists of real DeFi sites mean fewer false alarms.

This visit only

Continuing past a warning trusts the site only until you close the tab.

Misspelled address detection

Keyboard slips

Catches fat-finger typos like unoswap or opnsea.

Look-alike letters

Cyrillic, Greek, accents and tricks like rn posing as m.

Fake endings & extra words

uniswap.co, uniswap-v4.app, aaveapp.io, appuniswap.org.

Risk score

Each site gets a 0–100 score from several signals, so warnings stay meaningful.

Your watchlist

Guard any site you use — its misspellings are blocked too.

Recovery phrase shield

Phrase-stealing forms

Spots pages with 12–24 word boxes or that ask for your secret words.

Lock & cut off

Locks the boxes and blocks the page from sending anything out — without ever reading what you type.

Paste blocking

Stops recovery phrases being pasted into any website or chat before it can read them.

Private keys too

Ethereum, Solana and master private keys are blocked the same way.

Fake wallet support

Flags fake MetaMask, Ledger or Phantom help pages that ask you to sync or restore.

Wallet & frontend protection

Approval checks

Pauses unlimited approvals, approve-all NFTs, Permit and blind signatures.

Hijack alerts

Warns when a trusted exchange suddenly loads code from new places.

Private by design

Everything runs in your browser. Nothing is sent anywhere.
