Yes — if a user’s Lightning node supports NWC or CLINK, it becomes much easier for us to serve as a front-end UI for their Lightning wallet. We’ll also consider how to support Lightning nodes that don’t implement these two protocols.

Thanks. We understand this trade-off in NIP-17. In our view, the fact that NIP-17’s end-to-end encryption lacks forward secrecy and post-compromise security (PCS) is a more serious trade-off. We recognize that DMs and standalone chat apps are different applications, and therefore their choices of encryption protocols can also differ.

Keychat currently only has a Cashu wallet (which can also receive and send Lightning payments). We’re exploring a way to connect users’ existing Lightning wallets to Keychat, with Keychat serving purely as the front-end UI, while the wallet itself continues to run on the user’s own server or desktop. The main reason we’re considering adding Ark is that many users may not want to open and manage their own Lightning channels. We understand Ark’s trade-offs, and at this stage we believe they’re worth it.
