BAS Blockchain Address Search

Look up blockchain addresses and open exchange registration shortcuts from the popup.

BAS helps you look up public blockchain addresses without repeatedly copying and pasting them between websites. Select an address on a webpage and choose BAS from the right-click menu, or open the extension panel and paste an address. BAS checks its format and opens the corresponding blockchain explorer in a new tab. Additional lookup tools appear in the panel when applicable. No BAS account is required. The extension does not automatically read webpages, store your searches or include advertising. Your query is sent to the selected third-party explorer only when you choose to search. The interface follows your browser language, with English as the fallback. Address-format recognition does not verify an address’s existence or ownership.
