You have to try the desktop version of Keychat yourself to truly appreciate how much these four core tabs empower Bitcoiners and Nostr users.

New users, regardless of whether they use iOS or Android, can start with Keychat, which enables them to try nostr web clients within one minute. Keychat can also serve as a signer app to some extent. View quoted note →

It may be harder to persuade the Signal Foundation to add Bitcoin to the Signal app than to build a new chat app using the open-source Signal protocol and code. View quoted note →

We hope you’ll like Keychat’s custom-avatar approach. 1. We believe a chat app user’s avatar is different from a microblogging app user’s avatar and shouldn’t be publicly uploaded to relays. 2. Keychat can’t rely on a media server that promises long-term avatar storage. With the current avatar model, there’s no need for a long-lived media server. View quoted note →

What’s new: Wallet rebuilt on the official Cashu SDK. Note: your old transaction history can’t be migrated to this version—sorry for the incompatibility. Custom avatar and Lightning Address. Private by design: avatar and Lightning Address are stored locally and never uploaded to relays. They’re shared only when you choose “Send Profile,” embedded in end-to-end encrypted messages for true peer-to-peer propagation. Lightning transfers to a contact: if your chat partner has set and shared their Lightning Address, you can send a payment from the chat room’s settings page. Mini App browser polish: a virtual Home button (bottom-left or bottom-right). Long-press to return to the Browser; short-press to open the options menu. Delivery insights: messages now show how many relays delivered them—tap the number for details. Device Authentication support.

Perhaps unnecessary to emphasize: Keychat is primarily open-source local software; though it requires Message Relay, Media Relay, Cashu Mint, users can choose which to use rather than being bound to a single server. View quoted note →

Keychat Wallet currently only supports the Cashu Wallet. We plan to add two more types of wallets in the future: 1. To become the frontend interface for a server-side Lightning Wallet. 2. To support the Ark Wallet; we prefer this Ark implementation:

Four Types of Lightning Wallets In this discussion, “Lightning wallet” is used in a broad sense: any wallet that can send and receive Lightning payments is considered a Lightning wallet. 1. Lightning node wallets hosted on servers, such as Alby Hub. These typically have frontend wallets like Alby Go and Zeus. In this setup, the Lightning node runs on a server as the backend, while the phone wallet is just the frontend user interface, calling the backend Lightning node wallet. This is the most native form of a Lightning wallet. 2. Lightning wallets that run a Lightning node on the phone, such as Phoenix, Blixt, Breez, and Zeus (Zeus now functions both as a full mobile Lightning wallet and can also connect to a server-side Lightning wallet purely as a frontend). These wallets often rely on an LSP. Unlike a server-based Lightning wallet, a mobile Lightning wallet cannot remain online continuously. The two categories above are native Lightning wallets, where users open and manage their own Lightning channels. 3. Submarine-swap / nodeless Lightning wallets: Cashu Wallet, Aqua, Spark Wallet, Ark Wallet, Muun. These wallets do not require users to create channels. Users send and receive Lightning payments via the service provider’s channels, and BTC is stored as Ecash BTC, Liquid BTC, Spark BTC, Ark BTC, or on-chain BTC, rather than LN channel BTC. 4. Fully custodial Lightning wallets, such as Wallet of Satoshi (which now also supports Spark Wallet). As @Giacomo Zucco put it, “Lightning Network: the unified language for invoicing/swapping/routing across different Bitcoin security models!” Therefore, the latter two types—though they might not appear to be Lightning wallets at first glance—can also be regarded as Lightning wallets.
