Sigvoraa Wallet Shield

Browser extension · effective October 7, 2026 · applies to Sigvoraa Wallet Shield for Chrome

01 What this extension does

Sigvoraa Wallet Shield is a single-purpose extension: it intercepts the Solana transactions your wallet asks you to sign on a webpage, sends the transaction to Sigvoraa's risk-check service, and shows you a safe / caution / danger verdict before your wallet's own approval popup opens. It works across Solana wallets, not a single provider. It does nothing else.

02 What it reads from a page

To do this, the extension watches for the Solana wallet provider object (window.solana, and window.phantom.solana for Phantom specifically) that a Solana wallet injects on the pages you visit, so it can wrap three methods: signTransaction, signAllTransactions, and signAndSendTransaction. It does not read, store, or transmit anything else about the page — no page text, no browsing history, no clicks, keystrokes, or form data.

03 What data leaves your device

Only when you trigger one of the three signing methods above, the extension sends the serialized transaction itself (as base64, over HTTPS) to a single fixed backend:

Sent

The unsigned transaction bytes — program instructions, accounts, and amounts involved in that one transaction.

Destination

https://api.sigvoraa.com/api/shield/check — Sigvoraa's own risk-rules service, no other party.

Purpose

Compute a real-time risk verdict (safe / caution / danger) returned to the overlay shown on your screen.

Kept on device

A single on/off setting for whether protection is enabled, stored locally via chrome.storage.local. It is never sent anywhere.

04 What we don't collect

No names, emails, addresses, or other identifying information
No passwords, seed phrases, or private keys — the extension never has access to these
No browsing history or list of sites visited
No keystrokes, clicks, or page content
No advertising identifiers, and no analytics or tracking SDKs are bundled in the extension

Ordinary web infrastructure logging may still apply: like any HTTPS request, a request to our backend inherently carries your IP address and a timestamp as part of standard server operation. We do not use this for tracking, profiling, or identification, and it is not linked to any other data the extension handles.

05 Sharing and retention

We do not sell or share transaction data with third parties.
We do not use this data for advertising, profiling, or any purpose unrelated to producing the risk verdict.
We do not use this data to determine creditworthiness or for lending decisions.
Transaction data is used to compute the verdict returned to your browser; it is not required for the extension's core function to retain it beyond that.

06 Your choices

Open the toolbar icon any time to pause protection — while paused, no transaction data is sent anywhere. Uninstalling the extension removes the locally stored setting along with it.

07 Changes to this policy

If this policy changes, the updated version will be posted at this same link with a new effective date.
