Is Cobalt safe?
Cobalt lets allowlisted websites read its full local wallet storage through external messages.
Its manifest allows external connections from any URL, and the background worker checks a hard-coded origin allowlist before handling get-local-store. When one of those origins requests that method, the extension returns everything in chrome.storage.local, including stored wallet state, connections, permissions, networks, preferences, and the encrypted vault.

Where it sends data
Destinations our analysis observed Cobalt contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
