Features & Capabilities

No more flipping between tabs or copy-pasting into notepad. The extension lives in your browser's side panel (Chrome/Edge) or sidebar (Firefox) and stays visible while you browse.

Right-click copy — Select any text on a page, right-click, and choose "Copy to Crypto Address Checker 1" or "2". The panel instantly shows the text, the source URL, and whether the two slots match.
Smart hover extraction — Didn't select the full address? No problem. Right-click directly on any word without highlighting and the extension intelligently extracts the complete token under your cursor, stopping at whitespace, non-ASCII characters, or HTML boundaries. Perfect for long wallet addresses.
Manual override — Each slot has an "Allow manual input" checkbox. Enable it to type or paste directly into the textarea; disable it to revert to the last copied value. Edit on the fly when you need to test variants or fix formatting.
Live comparison — The MATCH / NOT MATCH badge updates in real time as you type, copy, or switch between tabs.

Designed for crypto, works for everything

Although built with crypto traders and DeFi users in mind, this is plain-text exact matching. Use it to verify URLs, order IDs, transaction hashes, PGP fingerprints, promo codes, or any snippet you need to cross-reference between two sources.

Privacy first - The extension does not collect, transmit, or store any data outside your local browser.

Is Crypto Address Checker Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Crypto Address Checker requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Crypto Address Checker is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
