Is Kastle safe?

Low risk

Kastle treats wallet requests from embedded frames as if they came from the connected parent site.

Its content script listens for postMessage wallet requests on every website without checking the message origin or source. On a site already connected to Kastle, a cross-origin embedded frame can trigger wallet actions that the background service handles under the parent site's host, including transaction-signing approval flows.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
