Bring ScamGuard risk context into the browser.

ScamGuard Web3 Shield is the official Chrome extension for the Tri-Proof security platform. It helps users review suspicious Web3 pages and signing context without taking custody of wallets or assets.

Official distribution is now handled through the Chrome Web Store. Use the store listing above for normal installation and future extension updates.
Current product scope

One ScamGuard engine, multiple access channels.

The Chrome extension complements the web scanner and Telegram bot. It is an access channel for the same ScamGuard security engine, not a separate custody or wallet product.

Page and destination context
Use the active page, destination domain, and available client signals to prepare a ScamGuard risk review.
Explainable warnings
Show the risk level, supporting signals, and recommended action instead of relying on an unexplained block screen.
Account-linked access
Connect through a short-lived request flow. Tri-Proof never asks the extension for a seed phrase or private key.
Secure connection flow

Install from Chrome Web Store. Confirm account links on Tri-Proof.

A valid extension request opens the protected Tri-Proof connection page with a request identifier. After sign-in, the user confirms the account link. Opening the connection route without a valid request does not grant extension access.

1Install ScamGuard Web3 Shield from the official Chrome Web Store listing.
2Start the connection from the installed extension.
3Review the Tri-Proof domain before signing in.
4Confirm only the account connection request you initiated.
What the extension may use
The active page URL, supported transaction context, user-triggered scan inputs, and the minimum account token needed for authenticated ScamGuard access.
What it must never request
Seed phrases, private keys, wallet passwords, or permission to move assets. Report any package or page that asks for them while claiming to be ScamGuard.
