A few stupid questions: 1) Is keychat fully open source? 2) How can it receive sats via LN but there is nothing about managing channels and liquidity? What LN server is it using under the hood? 3) What are the privacy implications? Does the Keychat team somehow see its users' cashflows? 4) what happens if the iOS App Store cracks down on this app and bans it? will all my data and balance be lost?

1) Yes 2) Currently, after the Keychat wallet receives a Lightning payment, it is stored as Cashu ecash sats. Users can choose which ecash mint to use. 3) Except for the Keychat relay, which is run by us, Keychat is a local app. We also don’t operate any Cashu mint. And no matter which Cashu mint you use, the operator cannot see your cash flow — that’s precisely the point of ecash.

4) Even if Keychat is removed from the App Store, existing users can still continue using the version they’ve already downloaded. However, it won’t be possible to update the app or for new users to download it from the App Store. You can export all your data in the settings and then import it into the macOS, Windows, Linux, or Android version of Keychat to keep using it.

The security of off-chain BTC is not uniform—counterparty risk increases in the following order: Lightning-Channel BTC → Ark BTC → Spark BTC → Liquid BTC → Cashu BTC → Custodial BTC. The Lightning Network is a channel layer plus a routing layer. If you run your own channel, the routing layer lets you settle payments directly. For the other five off-chain wallets, the operator shares its own Lightning channels with users, allowing them to send and receive Lightning payments. Liquid example • Paying — your wallet sends the same amount of L-BTC, and the operator pays the invoice through its channels. • Receiving — the operator first receives BTC over Lightning, then sends you the equivalent L-BTC. Liquid, Spark, and Ark can make users’ sending and receiving of Lightning payments atomic. Lightning is the transport network—other off-chain solutions plug in as special nodes. image
