Crypto Address Checker tekijä Allan Merolla

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.

1. 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.
2. 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.
3. 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.
4. 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.
