Statim vs SimpleX Chat

SimpleX Chat gives its users no identifier at all, not even a random one: each contact reaches you through its own pair of message queues. Statim goes the other way. Your twelve words give you an Ethereum address, a Nostr key and a Status chat key that people can write to, and the app puts those protocols and your Telegram and Matrix chats in one list.

At a glance

Feature	Statim	SimpleX Chat
Sign up with	Nothing	Nothing
Encrypted by default	On XMTP, Nostr and Status	Yes
Open source	Yes, MIT	Yes, AGPL 3.0
Your own server	Nostr, Status, Matrix	Yes
Wallet	Yes, off by default	No
Calls	No	1:1

Being found

With SimpleX, nobody can message you without a link or QR code you gave them, and the servers cannot tell that two queues belong to the same person. There is no directory and nothing to look up. Version 7.0 adds public names, registered on Ethereum, as a beta.

In Statim, people reach you by an Ethereum address or ENS name on XMTP, an npub… key on Nostr, or a zQ3sh… chat key on Status. That makes you easy to find. A first message from someone new waits under Requests until you accept it, and you can block a DM on every protocol.

Servers

SimpleX ships with two preset operators, SimpleX Chat Ltd and Flux, and lets you add your own servers. Since version 6.0 it can route messages privately, so the destination server never sees your IP address. Tor needs a separate proxy app.

Statim uses each protocol's own network: XMTP's nodes, the Nostr relays you choose, Status's nodes or your own, and the Matrix homeserver you sign in to. The developer runs none of them. None of them hides your IP address the way SimpleX's private routing does.

Encryption

SimpleX encrypts every DM and group with a Double Ratchet, and DMs also get a post-quantum key exchange. In its channels, added in 2026, the content is visible to the relays that carry it.

Statim's encryption is whatever the chat's protocol provides: MLS on XMTP, sealed DMs on Nostr, Status's own scheme, Olm and Megolm in encrypted Matrix chats, and none on Telegram. Every chat shows which applies.

Devices, calls and money

A SimpleX profile lives on one device; the desktop app links to your phone over the same local network. Statim runs the same account on a phone and a computer at the same time, from the same twelve words.

SimpleX has 1:1 voice and video calls; Statim has none. SimpleX has no wallet or token. Statim's wallet is a plugin for Ethereum and its chains, Bitcoin and Solana.
