If you operate your own Lightning channel, that’s the best case — you can use a fully native Lightning wallet.
If not, the five wallets mentioned above, each with their own tradeoffs, can still be used to send and receive Lightning payments by leveraging the service provider’s inbound liquidity. The difference lies in how “bitcoin” is stored under the hood — each takes a different form.
When both sender and receiver use the same provider and system, payments are typically settled internally without touching the Lightning Network. But if they’re on different providers, the payment is routed through the Lightning Network.

We've been using the metaphor of a letter: the envelope is where the sending and receiving addresses are written. To protect metadata privacy, both the sending and receiving addresses need to be updated frequently.
NIP-EE group events
{
"id": <id>,
"kind": 445,
"created_at": <unix timestamp in seconds>,
"pubkey": <ephemeral sender pubkey>,
"content": <NIP-44 encrypted serialized MLSMessage object>,
"tags": [
["h", <group id>]
],
"sig": <signed with ephemeral sender key>
}
In the NIP-EE group event, the content field is first encrypted using MLS, and then encrypted again using NIP-44. The NIP-44 encryption is done using a Nostr keypair generated from the MLS exporter_secret to calculate the conversation key value. Keychat follows the same approach. The public key—used as the sender address—is randomly generated, and Keychat does this as well.
The difference lies in the receiving address. In NIP-EE, the receiving address is set using:
"tags": [ ["h", <group id>] ]
The h tag represents the Nostr group ID (from the Nostr Group Data Extension). Updating the group ID requires a member to send a commit message.
Keychat, on the other hand, uses:
"tags": [ ["p", <receiverPublicKey>] ]
This receiverPublicKey is derived from the MLS exporter_secret, so it updates automatically without the need for a separate commit message.
Keychat uses kind: 1059, as it satisfies the constraints of kind 1059, enabling the integration of both MLS messages and NIP-17 DMs in a unified format.

Interoperability between the three clients in an MLS group isn’t hard, since they’re all built on OpenMLS and use shared relays.
The main difference is that Keychat uses a different “envelope” format for MLS messages compared to the other two clients. We need to write a note explaining the design rationale behind this “envelope” format, and we truly hope to have 0xChat’s understanding and support.

In MLS, multi-device sync is achieved by multiple device IDs (leaf nodes) sharing a single user identity. Each device has its own leaf but proves it belongs to the same user via the same identity credential.
Each device joins the same MLS group as a separate leaf node, but all represent the same user.

We are requesting the complete removal of version 1.20.3—not just from search results—because the error “installed version is higher, cannot downgrade” appears to be caused by the coexistence of two versions of Keychat (1.20.3 and the latest 1.32.4+6380). When users upgrade from version 1.31.13+6370, Zapstore compares it with 1.20.3 and triggers the error. However, upgrading from 1.20.2 does not cause this issue.

When a Cashu mint starts charging fees, it’s not just the sender who pays — the receiver is also required to pay a mint fee in most transactions. This is likely to cause confusion among users.🤔

Keychat attaches a 1 sat stamp to every message. But it doesn’t contact the Ecash mint server for each one. Instead, it fetches a batch of 1-sat ecash tokens in advance and uses them as needed to stamp messages.

I figured out what went wrong. If you double-click the receive button too quickly, you’ll get a “token spent” error. The first click already successfully received the tokens, and the second click tries to receive them again.

Here’s ChatGPT o3’s take on the history of using public keys as user IDs.
Since the invention of public-key cryptography in the 1970s, several consumer-facing applications have used the user’s public key directly as their ID:
• PGP / GPG (1991) – Users share a short PGP fingerprint (a hash of their public key) as their email identity.
• Bitcoin addresses (2009) – A Base58-encoded hash of a public key acts as the account for sending/receiving funds.
• Bitmessage (2012) – The “BM-…” address is a Base58 public-key hash used for encrypted mail and broadcasts.
• Tox ID (2013) – The long Tox string embeds the full public key; add it to start an E2E-encrypted chat.
• Tor .onion v3 / Ricochet IM (2014) – A 56-character .onion address is derived from an Ed25519 public key and serves as the chat ID.
• Secure Scuttlebutt (2014) – Feed IDs look like @<base64-public-key>.ed25519; the key is the permanent identity.
• Ethereum-style addresses (2015) – 0x… hashes of public keys function as login/payment accounts across smart-contract chains.
• Nostr npub (2021) – An npub is a Bech32-encoded 32-byte public key; any client can verify signatures from it.

How Keychat thinks about group
The essence of a group is to establish a boundary where only members can participate in communication. In a decentralized system, this boundary can only be enforced through encryption.
Groups generally fall into two categories: **chat groups** and **feed groups**. The former focuses on interaction—members are visible to each other, and messages are shared with the entire group. The latter is centered around content sharing—members are invisible to one another, and messages are individually encrypted for each recipient rather than broadcast to all.
Compared to chat groups, feed groups create much less social pressure, allowing both the sharer and the recipients to interact in a more relaxed and private environment.
#nevent1q…tldp

2025-05-09 03:14:37 GMT

At the core, it’s the same encrypted note — but the way it’s presented makes all the difference.
Form shapes essence.
The user knows the note will show up in their friends’ feeds, not in a chat room. That makes it feel more relaxed — it’s a message shared with many, not a direct conversation.
And for the friends who see it, there’s no expectation to reply, unlike with a DM.
#nevent1q…tyf2

2025-05-09 02:49:39 GMT

Maybe we could use NIP-17, which is used to encrypt DMs, to encrypt feed notes as well.
Suppose you have 10 friends — when you post a note, it’s essentially like sending 10 identical DMs.
However, the note still appears in the feed. Only your friends can decrypt and read it; others can’t see the content.

The seed phrase derives multiple IDs, which can serve as both chat IDs and browser IDs.
It also derives the private key used to recover the wallet.
Both chatting and using mini apps in the browser rely on the ID and wallet.

Web apps and PWAs can’t reliably support Signal or MLS protocol because those protocols depend on secure, persistent local storage and uninterrupted processing to keep cryptographic state (double-ratchets, MLS group keys and membership) up to date, whereas browsers only offer volatile storage and can’t guarantee continuous execution—so keys and session data risk being lost.

Tap the button in the top right corner of the MLS group chat to view the group details, where you can see the relays being used. Keychat automatically uses all of the user’s relays as the group relays by default. If a new member isn’t connected to the commonly used relays, they may not receive messages from other group members.
Maybe we should consider including the group’s relays in the welcome message, so that new members can decide whether to add them.

Centralized chat apps often enhance discovery by accessing users’ phone contacts — something Keychat doesn’t and can’t do by design. Instead, discovery on Keychat works more organically: when someone starts using it, they tend to invite friends who are also into BTC or Nostr. Keychat is primarily designed as a private messaging app for friends, rather than a platform for connecting with strangers. That said, it can still be used that way — for example, users can include their Keychat ID in their Nostr profile to make themselves discoverable.

2025-04-22 07:41:24 GMT

We feel that the term “Sats” became popular mainly because the price of BTC rose to around $100,000, making 1 sat equal to 0.1 cent — an amount that’s easy to recognize and remember. As owning a whole Bitcoin becomes increasingly difficult, it also drives the adoption of smaller units like sats. The symbol for sats should still be the BTC symbol. Sats also make it easier to measure micropayments made in Bitcoin.

Hi Water,
Keychat and NIP-104 are both based on OpenMLS, so they're about 95% similar. The main difference lies in how we rotate the message receiving address. I'll write a detailed post later to explain the advantages of our design. We also look forward to MLS clients being interoperable. Please don't misunderstand us as intentionally being different.

Signal: Ratchet advances inline with message sending — no extra messages needed.
MLS: Requires extra protocol messages (Update proposals and Commits) to advance the key state and ensure post-compromise security.

Keychat users can ask the AI bot questions and pay per message with ecash Cashu sats. This is different from the sat stamp paid to the relay — it’s paid to the bot.

We submitted Keychat to the App Store and Google Play last Monday, and it’s currently under review. In the meantime, the Android APK and macOS version are available for download at: https://www.keychat.io/
If you’re an existing Android user, please note that the new version of MLS groups is not compatible with the previous one. After upgrading, you will no longer have access to your old MLS groups.

Some updates:
We've finally sorted out the Apple developer account. We expect to release the iOS version of Keychat within a week or two, and possibly a macOS version as well (although the UI isn’t fully optimized for large screens yet).
We're currently revising our MLS group implementation. We've studied the codebases of NIP-104 and White Noise in depth and learned some useful design ideas—such as encrypting MLS messages using NIP-44 and hiding the `group_ID`. We’ve also been posting comments and discussing better mechanisms, like more efficient ways to update the MLS group’s receiving addresses. Ultimately, we hope different MLS clients will be able to interoperate.

For a chat app, it only takes you and a friend using it for it to be useful—since your messages go directly to them.
A microblogging app, on the other hand, needs a critical mass of users to be effective—because your posts are broadcast to everyone, and the more users there are, the more interaction you’ll get.
Maybe that’s why there are more chat apps than microblogging apps.

We are still improving and optimizing MLS groups. Please note that future MLS groups may not be compatible with the current version.

Let’s make Keychat’s MLS groups and 0xChat’s MLS groups interoperable in the near future.

Thanks. For us, this is a journey with an unpredictable outcome, but one worth pursuing.
