In the fast-evolving world of cryptocurrency, staying secure and informed is more important than ever. Whether you're trading NFTs, swapping tokens, or simply managing your digital assets, two critical concerns consistently arise: managing Ethereum gas fees and avoiding phishing websites. To tackle both challenges in one streamlined tool, a new Chrome extension—GAS & Link Checker—has been developed to empower crypto users with real-time data and proactive security alerts.
This lightweight, open-source browser extension provides three core functionalities: live Ethereum gas fee tracking, a curated bookmark system for trusted crypto platforms, and intelligent phishing detection based on URL similarity analysis. Let’s explore how each feature enhances your web3 browsing experience.
Real-Time ETH Gas Fee Monitoring
One of the most frustrating aspects of interacting with the Ethereum network is unpredictable transaction costs. The GAS & Link Checker extension simplifies this by displaying current gas prices directly in your browser toolbar.
- Current Gas Fee: Reflects the average cost per transaction in the latest block. This is ideal for standard transfers or non-urgent transactions.
- Recommended Gas Fee: Slightly higher than average, ensuring faster confirmation times—perfect for time-sensitive actions.
- High-Priority Transactions: When participating in NFT mints or competitive DeFi trades, consider multiplying the recommended rate by 2x or more depending on urgency (commonly referred to as "FOMO pricing").
By having these metrics instantly accessible, users can make informed decisions without navigating away to third-party gas trackers like Etherscan or GasNow.

Secure Bookmarks for Trusted Crypto Platforms
A major vector for crypto theft comes from misleading search results. Many phishing sites rank highly on Google or run paid ads that mimic legitimate platforms such as Uniswap or CoinGecko. A single wrong click can lead to irreversible asset loss if you unknowingly approve a malicious contract.
To combat this, the extension includes a secure bookmarking system preloaded with essential, verified crypto websites:
- Coingecko (www.coingecko.com): Your go-to source for comprehensive token information, market data, and official links.
- Uniswap & PancakeSwap: Leading decentralized exchanges on Ethereum and Binance Smart Chain, respectively.
- DexTools & Poocoin.app: Powerful tools for analyzing token charts, liquidity pools, and trading volume in real time.
You can also add new bookmarks manually using the “Add current web page to official links” button, ensuring only trusted sites are saved. Once stored, these become reference points for the extension’s anti-phishing engine.
The key takeaway? Stop relying on search engines for crypto navigation. Use curated bookmarks instead to minimize exposure to fraudulent domains.
Advanced Phishing Website Detection
Even experienced users can fall victim to cleverly crafted phishing URLs. Consider these two addresses:
https://clonex.rtfkt.com/(official)https://clonex.rlfkt.com/(fake)
The difference? Just one letter—"t" vs "l"—easily missed at a glance. That small change could redirect you to a counterfeit site designed to steal your wallet credentials or trick you into signing malicious transactions.
The phishing detection feature compares any visited URL against your saved bookmarks using string similarity algorithms. If a match exceeds 70% similarity, the extension triggers an immediate warning popup, alerting you that the site may be spoofed.
This proactive defense mechanism adds a crucial layer of protection, especially during high-stress moments like NFT drops or flash crashes when users act quickly and may overlook subtle URL discrepancies.

Open Source & Privacy-First Design
Transparency builds trust—especially in crypto. That’s why this Chrome extension does not collect user data and contains no tracking scripts like Google Analytics. Your browsing behavior remains private.
Moreover, the entire source code is publicly available on GitHub (github.com/hsuanchi/Gas-Link-Checker), allowing developers to audit, contribute, or propose improvements via pull requests. This open approach ensures accountability and fosters community-driven development.
Frequently Asked Questions (FAQ)
Q: Is the GAS & Link Checker extension free to use?
A: Yes, the extension is completely free with no hidden costs or premium tiers.
Q: Does it work only on Ethereum-based sites?
A: While gas fee tracking focuses on Ethereum, the bookmark and phishing detection features support any website, making it useful across multiple blockchains.
Q: How accurate is the phishing detection algorithm?
A: It uses Levenshtein distance-based comparison to detect visually similar URLs. While highly effective, no system is 100% foolproof—always double-check URLs manually when in doubt.
Q: Can I sync my bookmarks across devices?
A: Currently, bookmarks are stored locally in your browser. Syncing would require integration with Chrome's sync services in future updates.
Q: What should I do if I encounter a phishing site not detected by the extension?
A: Report it via the GitHub repository so the team can improve detection rules and warn other users.
Q: Does the extension slow down my browser?
A: No. It runs efficiently in the background with minimal resource usage and no impact on page load speed.
Staying safe in the decentralized web requires vigilance—and the right tools. With real-time Ethereum gas tracking, secure bookmark management, and smart phishing alerts, this Chrome extension delivers practical value for every crypto user.
Whether you're a beginner navigating your first DeFi platform or a seasoned trader monitoring gas spikes during NFT mints, integrating this tool into your workflow enhances both efficiency and security.
