Nexus for XMTP

An independent XMTP client and agent layer in your browser side panel. Not affiliated with XMTP Labs.

Nexus puts a real XMTP client in your browser side panel: a universal inbox, consent based request filtering, direct messages, groups, replies, reactions and attachments. It adds three agents a coordinator, a research agent and a security agent that each hold their own XMTP identity. They coordinate by messaging each other over XMTP rather than through internal calls, so you can open the same conversation in any other XMTP app and watch the whole exchange. WHEN THE AGENTS DISAGREE, NEXUS SAYS SO FIRST Most systems merge several answers into one confident paragraph, and whatever the agents conflicted about disappears. Nexus leads with the conflict instead and distinguishes "the other agent disagreed" from "the other agent never looked", which are very different situations. WHAT IT DOES • Universal inbox with live message streaming • Requests tab unknown senders cannot notify you until you accept them, and that decision syncs to every XMTP app you use • Direct messages and groups • Replies, reactions, image and file attachments • Share the page you are on into any conversation • Multi-agent rooms a real XMTP group where you watch the agents work PRIVACY BY CONSTRUCTION Nexus never asks for a seed phrase or private key and stores neither. It cannot sign or send a transaction: proposals are validated, decoded for you to read, and handed to your own wallet for approval. Nothing is read from any web page unless you ask. When you share a page you see exactly what will be sent first credentials, tokens and tracking parameters are stripped, and you are shown what was removed. No analytics. No telemetry. No crash reporting. CURRENTLY ON THE XMTP DEV NETWORK This build connects to the XMTP dev network, which is a test network. State there is not guaranteed to persist. Not affiliated with XMTP Labs or Ephemera. "Built-in agent" means shipped with Nexus, not verified by XMTP.
