Wallet-drainer & phishing guard for Chrome

See the scam before you sign.

Signward sits between the page and your wallet. It reads every risky request in plain language and blocks known scams before the page can run.

Deep analysis of this tab

Wallet gate

Approvals and orders, in plain words.

Approval alerts

Warns if a contract is later hacked.

Protection at every step of a wallet attack

Most drainers follow the same path: a convincing page, a wallet prompt, a signature. Signward breaks that chain in more than one place.

Plain-language wallet gate

Every approval, permit, Permit2 and marketplace order is decoded before you sign. Unlimited spends and setApprovalForAll are flagged, and the counterparty is screened against scam lists.

Scam sites blocked on load

Known phishing hosts and brand-impersonation lookalikes — including short-name clones and IDN homographs — are stopped with a full-page warning before a single script runs.

On-chain address screening

Counterparty addresses are checked against sanctions and malicious-address data, so you are warned when a spender or site is already known to be dangerous.

Compromised-approval alerts

Signward remembers what you approved. If a contract you trusted is later exploited, it warns you on the spot and takes you straight to revoke it.

Seed-phrase & clipboard guard

Warns when a page tries to collect your recovery phrase, and catches ClickFix / fake-CAPTCHA pages that copy a hidden system command to your clipboard.

AI deep scan, on demand

Not sure about a page? One click sends a snapshot for an AI second opinion that explains, in plain language, exactly why a page looks safe or dangerous.

Four layers, working together

Each layer is useful on its own. Together they cover the page, the wallet request and the counterparty.

On-load page check

Scores the site on your device against blocklists, brand data and on-page signals, then warns or blocks.

Wallet gate

Holds risky requests and shows them in plain language, with a live simulation, before they reach your wallet.

Address screening

Checks the counterparty against sanctions and malicious-address lists, online or from bundled offline data.

Deep scan

An on-demand AI verdict for the pages the fast checks are unsure about, with reasons you can read.

Built to see less, not more

A security tool should not become the thing you have to trust with everything. Signward checks pages on your device and keeps your keys and browsing to yourself.

✓Your keys are never touched. Signward reads and explains requests; it never holds a seed phrase or private key, and it cannot sign for you.

✓Full URLs are never sent or logged. Page scoring runs locally, and the approvals you make are stored only on your device.

✓No accounts, no tracking, no ads. There is nothing to sign up for, and nothing is sold.

What leaves your device, and only then

A few checks need a server. Each sends the minimum: an address for online screening (optional, on by default), a domain for an age lookup on a suspicious page, and a page snapshot for the AI deep scan — which runs only when you click it.
