Why Use the Etherscan Browser Extension?

In the fast-moving world of Ethereum, timing is everything. High gas fees can turn a profitable transaction into a costly mistake. The Etherscan extension helps you stay ahead by delivering accurate, up-to-the-minute gas pricing data right in your browser toolbar.

Beyond gas tracking, the extension enhances your browsing experience with contextual Ethereum address searches. Simply highlight any wallet or contract address while surfing the web, right-click, and select “Search in Etherscan” to instantly pull up full transaction history, token balances, and contract details.

This level of integration saves time and reduces errors — especially helpful when navigating decentralized finance (DeFi) platforms, NFT marketplaces, or auditing smart contracts.

Key Features at a Glance

🔹 Real-Time Gas Price Monitoring

The extension displays current Ethereum gas fees through an intuitive badge on your browser’s toolbar. Updated every 30 seconds, it shows both Gwei and USD-equivalent values with precise decimal formatting for clarity.

You can customize alerts to notify you when gas prices drop below a certain threshold — ideal for scheduling low-cost transactions during off-peak hours.

🔹 One-Click Address Lookup

No more copying and pasting addresses into Etherscan manually. With a simple highlight and right-click, users can instantly search any Ethereum address directly from web pages, forums, or social media.

This feature supports wallet addresses, smart contracts, and token contracts — making it invaluable for security checks or due diligence before interacting with unfamiliar entities on-chain.
