BarryGuard Extension v1.5: 23 Checks, 9 Platforms, Open Source

The last publicly released version of the BarryGuard Chrome extension was v1.0. Since then, we have rebuilt nearly every part of it. Version 1.5 is the result — a ground-up upgrade that goes from 8 checks to 23 on-chain checks, supports 9 Solana platforms, and introduces a completely redesigned interface with a premium score gauge, rug warning banners, and a built-in watchlist.

The extension is and always has been fully open source. Every line of code is publicly available on GitHub. You can read the source, verify what the extension does, and confirm that it never touches your wallet.

From 8 Checks to 23

The original extension displayed results from 8 on-chain checks. Version 1.5 runs the full BarryGuard engine with all 23 checks, including mint authority, freeze authority, liquidity lock status, holder concentration, creator retention, developer history, update authority, liquidity ratio, early dump patterns, sniper dominance, sellability, and Token-2022 extension scanning.

Every check that runs on the web checker now runs identically in the extension. There is no reduced or simplified version — the extension delivers the same depth of analysis as the full site.

9 Supported Platforms

The extension injects risk overlays directly into the pages you already use to trade. Version 1.5 supports nine platforms:

• Pump.fun — token pages and new listings
• PumpSwap — graduated token pools
• Raydium — swap and pool pages
• DexScreener — pair pages and list views
• Birdeye — token detail pages
• Moonshot — token launch pages
• LetsBonk / Bonk.fun — token pages
• Bags.fm — portfolio and token views
• Solscan — token detail and account pages

On each platform, the extension detects the token address from the page context and displays a color-coded risk badge inline. On detail pages, clicking the badge or the extension icon opens the full analysis popup with all 23 checks, the score gauge, and any active warnings.

Five-Level Risk Scoring and Score Gauge

Version 1.5 introduces a five-level risk classification: Safe, Low Risk, Moderate, High Risk, and Danger. Each level has a distinct color and label so you can assess a token at a glance without reading every individual check.

The popup now features a premium SVG score gauge — a glassmorphic arc with a glow effect that displays the overall risk score, the risk level label, and the token name in a single visual. It is designed to communicate the result immediately and unambiguously.

Rug Warning Banners

When the engine detects a Danger-level token, the extension now displays a rug warning banner directly on the trading page. This is a prominent, hard-to-miss alert that appears before you interact with the token — not buried inside a popup you might forget to open.

The banner shows the risk level, the primary reason for the classification, and a link to the full analysis. It is intentionally aggressive because the situations that trigger it — active mint authority, extreme holder concentration, known rug patterns — warrant clear, unambiguous communication.

Watchlist and Alerts

You can now add tokens to a watchlist directly from the extension popup. Watchlisted tokens are monitored for changes in their risk profile. If a token you are watching changes risk level — for example, if its liquidity gets pulled or its mint authority gets re-enabled — you receive an alert.

The watchlist lives in the extension popup under the new actions panel. It is designed for traders who hold positions and want to be notified if the risk profile of their holdings changes after purchase.

Batch List Scanning

On platforms that display token lists — like DexScreener trending pages or Pump.fun new listings — the extension scans multiple tokens in parallel and displays risk badges next to each one. You can see at a glance which tokens in a list are flagged and which appear clean, without clicking into each one individually.

This is particularly useful for traders who browse new listings. Instead of checking tokens one by one, the extension surfaces risk signals across an entire page of tokens simultaneously.

Security and Transparency

The extension requests only two Chrome permissions: storage (to save your preferences locally) and scripting (to inject risk badges into supported platforms). It does not request access to your wallet, your browsing history, or any data beyond the supported trading platforms.

Since v1.0, the extension has undergone a full security audit. All innerHTML usage has been replaced with safe DOM APIs to prevent XSS. Sender validation, address sanitization, and TOCTOU guards have been added to the background service worker. Session tokens are handled through a content script acting as the sole auth authority, eliminating an entire class of tier and quota bugs.

Most importantly: the extension is fully open source. The complete source code is available at github.com/ZivCore/BarryGuard-Extension. You do not need to trust our word that the extension is safe — you can read every line yourself. If you are a developer, you can build it from source and load it as an unpacked extension. The code is the proof.

No Wallet Access

BarryGuard has never requested and will never request access to your wallet. The extension reads publicly available on-chain data to analyze tokens. It does not sign transactions, it does not read your balances, and it does not interact with any wallet provider. This is a read-only tool by design.

Install It Now

Version 1.5 is live on the Chrome Web Store. Install it, navigate to any supported platform, and the risk overlays appear automatically. No configuration required.

Disclaimer

BarryGuard provides risk indicators based on on-chain data and internal scoring logic. It is not investment advice. A low-risk score does not guarantee safety, and a high-risk score does not guarantee fraud. Always do your own research before trading any token.
