We made a five-minute overview video of Keychat to help viewers understand its overall design.

This video finally made me try out Keychat again. From what I can see in two minutes of logging in and poking around is this is very well done and fully functional. You don't NEED to *buy* anything to use it, even though the literature leads with the concept of needing to "buy postage". Howevrr it's not necessary to futz with money or buy anyone's tokens to try it out. This makes onboarding friends 100% easier than I assumed. Keychat not only operates on ecash in a 'tipping the relay' capacity (ostensibly for postage), but the built-in wallet that supports this tipping is not half-assed or shoehorned in. It can be used to send money to friends, or pay for things on websites. The CashU wallet is integral to the app and even offers serving up your balance to other apps via NWC! The dual-function of chat + browser with nostr login support is a vision you can only understand by seeing it for yourself. Look with your own eyes, install it! It costs you nothing. Nostr + lightning in a browser on your phone without clunky broken chrome plugins that need a password every time you want to fail trying again??? Heresy! Finally, the most important part: Nostr support. This is a FULL FLEDGED nostr app, not a shitstorm of broken trash and single-use identities like most apps that attempt more than one feature with nostr. Neither is this is a polished turd, it actually works (the first time!) It supports (a) make your own identity, (b) past in your existing key, and (c) AMBER NOSTR SIGNER! Who knew? Kudos Keychat!

Keychat already supports this feature — users can share their own Keychat links.
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

You should really consider a new name for your product. It's totally misleading. Everyone expects just a chat app when in reality your app could be the one stop to explore the whole nostr ecosystem.

Naming it Keychat (Key + Chat) used up all our spark. We riffed on Bitcoin’s wordplay (Bit + Coin). Still craving ideas. 😅

Thank you for helping the world discover Keychat.
It is a pleasure to install Keychat on my new android 14+ smartphone. I have a 9+ who is no fit for the app, but I found a solid solution.

May I ask what exactly you mean by “icon themes”?

Hi Gigi, if you mainly use a Nostr login extension and a Lightning wallet extension on mobile browser, you might want to check out Keychat. We think you’ll like it. nevent1qvzqqqqqqypzpwleyw4fy3sxt7yvgrran0mpenxqlululur94r9jlax0hd3q3rc7qyxhwumn8ghj7mn0wvhxcmmvqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsz9nhwden5te0wfjkccte9ehx7um5wghxyctwvsqzq62fl0fs5ge8xmd8p6594lc55d780rgec35j6z4r28twmt2gal2dvwwqhr
