In the new Keychat, the four bottom tabs stay visible while you use Mini Apps in the Browser, so you can easily switch between tabs.

As part of the Keychat rewrite, we’ve also added explanations of ID and Seed Phrase to the Me page.

As part of the Keychat rewrite, we’ve also added a new introduction to Keychat Wallet.

We've added a new Mini Apps introduction to Keychat Browser in the upcoming Keychat rewrite.

In the Keychat rewrite, we’ve finally implemented a native Stamp Token powered by the Cashu protocol — a true utility token with real-world use cases.

We haven’t posted here in a while. Over the past months, we’ve been rewriting Keychat natively. We’re still working hard on it. More to come. View quoted note →

We’re happy to see that users understand and appreciate the design of Keychat Mini Apps — combining web apps, public key login, and a Bitcoin wallet. BTW, we plan to add a Public Agent alongside Mini Apps later on. View quoted note →

Attaching a Stamp (Client → Relay) When publishing an event to a relay that requires stamps, the client appends a Cashu token as the third element of the EVENT message array: ["EVENT", <event JSON>, "<cashu_token>"] View quoted note →

We are close to completing the development of libkeychat. libkeychat is to the Keychat protocol what libsignal is to the Signal protocol. After libkeychat is released, users should be able to quickly build their own clients using Pi agent, Claude Code, or Codex. View quoted note →

Keychat protocol is a sovereign messaging stack that integrates five layers: Identity — Nostr keypair, self-custodial with no server dependency Transport — Nostr relay network, open and self-hostable Encryption — Signal Protocol for 1-to-1 and small group chats, MLS for large group messaging Addressing — Receiving and sending addresses are decoupled from identity and continuously rotate Stamps — Cashu ecash tokens attached to messages as anonymous micropayments to relays View quoted note →

This NIP defines a mechanism for clients to attach ecash tokens (Cashu) to Nostr events as stamps — anonymous per-event micropayments to relays. Stamps solve two fundamental problems for the Nostr relay ecosystem: spam prevention and relay sustainability.

Maybe agents will adopt sovereign messaging before humans do. Humans are still locked into big-tech chat apps by network effects and habit, while agents can switch to open, self-sovereign protocols much faster. Then humans may end up learning from agents—gradually moving to sovereign messaging themselves. It’s a strange inversion. View quoted note →
