Keychat users can choose which message relays to use — both free and paid ones — and they can also delete the default Keychat relay.

Therefore, it’s completely possible to use Keychat even without any ecash sats.

One of the reasons we built Keychat is that Signal only allows users to use servers operated by Signal itself. In contrast, with Keychat, users decide which message relay to use — we never force anyone to rely on a specific relay.
