Statim is a free, open-source encrypted messenger for people who want to own their account instead of trusting a company with it. It runs on Windows, macOS, Linux, Android and iOS, and this page covers the Windows build or installer. There is no sign-up form, no phone number and no email address. Your account is a twelve-word phrase generated on your device.
Statim for Windows suits privacy-minded users, people already active on Nostr, and anyone who wants conversations from several networks in one place. The same phrase also unlocks an Ethereum, Bitcoin and Solana wallet, so the app works as both a messenger and a crypto wallet. The project is released under the MIT license, and its most recent code update is dated October 30, 2026. Read on for installation, features and safety notes before you store any funds.
What Is a Self-Custodial Messenger?
A self-custodial messenger is an app where you, not the company behind it, control the keys that identify your account. Most chat services tie your identity to a phone number or email address and keep recovery tools on their own servers. Statim takes a different route. The account is a twelve-word phrase generated on your device, and that phrase is the only proof of ownership.
That design has real advantages. Nobody can reset your account for you, and there is no central database of user identities waiting to be leaked. It also has a clear downside: if the phrase is lost, no support desk can restore access. Think of it the way you would think of a house key that no locksmith can copy.
The same idea extends beyond messaging. Because the phrase also controls an Ethereum, Bitcoin and Solana wallet, it becomes the single secret for both conversations and funds. That convenience is exactly why the phrase deserves more protection than an ordinary password. Store it offline and treat it as the master key to everything in the app.
How Multi-Network Messaging Works
Statim does not rely on a single messaging network. It connects to XMTP, Nostr and Waku, and it can also bring Telegram and Matrix conversations into the same inbox. Each of these networks has its own design, so one app can show very different kinds of chats side by side.
For a user, the benefit is consolidation. Instead of switching between several apps, you read messages from different services in one window. Tools such as search and folders help keep that combined view manageable during a busy day.
The trade-off is that privacy depends on the network a message travels over. A conversation on a Nostr relay follows different rules than one on Matrix or Telegram. Reading everything in one inbox does not mean every channel offers the same protections, so it helps to know where each contact actually lives.
Who Is Statim For?
Statim suits a few clear groups of people. Privacy-minded users who do not want to hand over a phone number are a natural audience, since the app asks for no sign-up details. People already active in the Nostr ecosystem will recognize its key-based approach, and those who hold crypto may appreciate messaging and a wallet tied to one phrase.
A typical scenario: a freelancer keeps client chats in one folder and personal chats in another, and uses a second account on the same Windows PC for a side project. Each account keeps its own encrypted history, so the two worlds stay separate. Another scenario is someone who receives messages across several services and wants them in one window instead of four apps.
Statim is less suitable for people who expect a conventional app with a support team that resets passwords. It also asks users to handle their own recovery material, which takes discipline. Anyone who prefers account recovery through an email address will find that trade-off uncomfortable.

Supported coins
Statim's wallet covers Bitcoin (BTC), Ethereum (ETH) and Solana (SOL), all derived from the same twelve-word phrase that identifies your account. On the messaging side, the app connects to XMTP, Nostr and Waku, and it can bring Telegram and Matrix conversations into the same inbox. Hardware wallets Ledger, Trezor and Keystone are listed among supported devices, so you can keep signing keys offline if you prefer.
How to install Statim on Windows
- 1
Get the Windows build
Download the Windows build or installer from the official website or from the project's GitHub Releases page at github.com/alaibe/statim. Stick to these two sources, because copies hosted elsewhere may have been altered.
- 2
Verify the file
Compute the SHA-256 checksum of the downloaded file, for example with Get-FileHash in PowerShell, and compare it with the value published on the release page. If the values do not match, delete the file and download it again. If the release also provides a signature, check that too.
- 3
Run the installer
Open the installer and follow the prompts. Choose an install folder you can find later, and let setup finish before you launch the app.
-
Create your first account
Open Statim and choose to create a new account. The app generates the twelve-word phrase on your device. Write it down before you do anything else, and follow the steps in How to Use below.
How to use Statim
Once Statim is installed, setting up your account takes only a few minutes. Start with the account, then add conversations and wallet features at your own pace.
- Open Statim and choose to create a new account.
- Write the twelve words shown on screen on paper and store that paper somewhere offline.
- Follow the prompts to confirm you saved the phrase, then set up your profile.
- Open the requests area to review messages from people you have not accepted yet.
- Create folders for work, family or projects so conversations stay organized.
- Add the other networks you use, such as Telegram or Matrix, to bring them into the same inbox.
- Turn on the wallet only when you need it, and double-check the receiving address before sending any funds.
If you later want a second account, add it from the account menu. Each account keeps its own encrypted history, so you can separate personal and work chats on the same Windows PC.
Pros & cons
- Free and released under the MIT license, with source code on GitHub
- No phone number, email address or sign-up form required
- Conversations from XMTP, Nostr, Waku, Telegram and Matrix in one inbox
- Encrypted local history with a separate store for each account
- Link previews fetched by your own device rather than a server
- Built-in wallet for Bitcoin, Ethereum and Solana using the same phrase
- The twelve-word phrase is the only recovery route, so losing it means losing the account
- The wallet and dapp browser are not part of a fresh install, so crypto features take extra steps to reach
- Privacy varies by network, which can be confusing when one inbox mixes several services
- Messaging behavior differs between networks, so some chats may feel less consistent than others
Is Statim safe?
Statim is open source under the MIT license, so its code can be reviewed publicly on GitHub. Download only from the official website or the GitHub Releases page, and compare the SHA-256 checksum of the file with the value published alongside it. If a release offers a signature, verify that as well. Never type your twelve-word phrase into a website, pop-up, chat or support message that claims to come from Statim, because anyone who gets it can take over the account and the wallet. The most recent code update is dated October 30, 2026, so check the latest version on the official website before you install it.
- Official source only. Download from github.com/alaibe/statim. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Statim sits in a different place than the other Nostr-based programs in this catalog. Vector is a privacy-focused encrypted messenger built on Nostr using NIP-17, while Nostrid is a multi-platform Nostr client. Bold Bitcoin Wallet concentrates on Bitcoin wallet security through MPC signing over Nostr. Statim combines conversations across several networks with a built-in Ethereum, Bitcoin and Solana wallet under one twelve-word phrase. If you want a Nostr-focused client, Vector or Nostrid may suit you better. If you want chat and a wallet in one place, Statim is the closer fit.

Frequently asked questions
Statim is open source under the MIT license, so its code is publicly available for review. Safety depends mostly on where you get the installer and how you handle your twelve-word phrase. Verifying the file's checksum and keeping the phrase offline matter most.
No. Statim does not ask for a phone number, email address or any sign-up form. Your account is created on the device, and the twelve-word phrase is the credential that identifies it. Because no company holds a copy of that phrase, there is no password reset option if you lose it.
Yes. Statim is free to download and use, and its source code is published under the MIT license. Nothing about the program suggests paid tiers, so a typical user should not expect to pay to chat or to use the wallet.
Yes. Statim can bring Telegram and Matrix conversations into the same inbox as its other networks. Messages still travel over those services' own infrastructure, so the privacy level depends on each network. Treat Statim as one place to read everything, not as a single privacy guarantee across every channel.
Statim's wallet covers Bitcoin (BTC), Ethereum (ETH) and Solana (SOL). All three are derived from the same twelve-word phrase that identifies your account. The project also lists Ledger, Trezor and Keystone hardware wallets, which let you keep signing keys offline.
Yes. Statim supports several accounts on one device, and each account keeps its own encrypted history database. That setup lets you keep personal and work conversations apart without mixing their message histories.
A Nostr messenger is a chat app built on the Nostr protocol, an open network of relays that carries signed messages between users. People are identified by cryptographic keys rather than phone numbers. Statim uses Nostr as one of its networks, so the key-based model is part of how the app works.
Verdict
Statim suits people who want an encrypted messenger without giving a phone number or email address, and who are comfortable keeping a twelve-word phrase safe. It is free, open source and available for Windows along with other platforms. Its main value is the combination of chat across several networks and a built-in wallet. If you lose the phrase, you lose access, so back it up offline before you start. Try it with a small, low-stakes account first to see whether the workflow suits you.
