Cosmosvanity is a free command-line tool for Windows that generates Cosmos addresses containing a pattern you choose, such as a run of zeros or a chosen string of characters. It is aimed at people who hold or plan to hold Cosmos (ATOM) and want an address that is easier to recognize, as well as anyone curious about how vanity addresses work. Before you start, note that the latest code update dates to May 23, 2022, more than two years ago, so this is a finished tool rather than one in active development.
The program is written in Go and ships as ready-made binaries for Windows, macOS and Linux, with version 1.0.0 as its latest release. Its strength is simplicity: it does one job, searching for matching Cosmos bech32 addresses, and it does that job from a terminal. That makes it a good fit for technical users comfortable with the command line, and a poor fit for anyone who wants a graphical interface.
What Is a Vanity Address?
A vanity address is a crypto address that contains a pattern you choose, such as a specific sequence of characters near the beginning. Software creates candidate keys and derives their addresses, then checks each one against the pattern. When a candidate matches, you keep it. Everything else is discarded.
People use vanity addresses for several reasons. Some want an address that is easy to recognize when they share it, while others enjoy the technical challenge of building one. A distinctive address can also make it easier to confirm, at a glance, that you copied the right destination.
The pattern changes how the address looks, not how well the underlying key is protected. A vanity address is no safer than any other address generated the same way. Its security depends on how you store and handle the key material, which is a separate question from the pattern you chose.
Who Cosmosvanity Is For
Cosmosvanity suits people who already work comfortably in a terminal. Developers who want to understand how vanity generation works will find the tool easy to test on a single machine. Hobbyists who hold Cosmos (ATOM) and want a memorable receiving address may also find it useful.
Consider a typical scenario. A user sets up a Windows PC, downloads the binary, and runs a short search with a five-character pattern to see how the process feels. The first run teaches more than any description could, including how long searches take and how the output looks. Once that is clear, the user can decide whether longer patterns are worth the wait.
The tool is less suited to people who expect a graphical interface, guided wizards or a dashboard of results. It assumes you are willing to read a few options, enter settings by hand and manage the output yourself.
Understanding Cosmos Addresses and the Bech32 Format
A Cosmos address begins with a human-readable prefix, which for standard addresses is cosmos1. After the separator, the address contains encoded data followed by a checksum. The prefix tells you which network an address belongs to, so an address with a different prefix is not meant for the Cosmos chain.
Bech32 is the encoding behind this structure. It uses a 32-character alphabet made of lowercase letters and digits, leaving out a few characters that are easy to confuse. The checksum at the end lets wallets and tools detect many typing mistakes before funds are sent.
Understanding this format matters for vanity work. Because the prefix is fixed, any pattern you search for must fit within the characters that come after it. This is why patterns are often described as text that appears after cosmos1 rather than anywhere in the address.
How a Vanity Search Works Behind the Scenes
Every vanity search follows the same loop. The program generates a candidate key, derives the address from it, compares the address with the pattern and then repeats. Each attempt is independent, so the process is a matter of probability rather than a clever shortcut.
The math explains why patterns grow hard so quickly. With a 32-character alphabet, each extra character in a fixed pattern multiplies the expected number of attempts by roughly 32. A pattern one character longer is therefore far more demanding, not just slightly slower to find.
This is also why hardware matters. Using every processor core increases the number of candidates checked per second, but it cannot change the underlying odds. Good planning means choosing a pattern that matches how much time you are willing to spend.

How to install Cosmosvanity on Windows
- 1
Download the Windows build
Go to the project's GitHub Releases page and download the Windows build from the latest release. Download only from the official website or the project's GitHub repository, not from mirror sites or file-sharing pages.
- 2
Verify the file
Check the SHA-256 checksum or signature if the release page provides one. In PowerShell, run Get-FileHash on the downloaded file and compare the result with the published value. If they do not match, delete the file and download it again from the official source.
- 3
Place the program in a folder
Move the executable into a folder you control, such as a dedicated tools directory. Keeping it in one place makes it easier to find, remove later and recheck its hash.
-
Open a terminal and confirm it starts
Open Command Prompt or PowerShell in that folder. Start the program once to confirm it launches on your system before you run any real search.
How to use Cosmosvanity
Cosmosvanity is driven entirely from the terminal, so the workflow is about choosing the right search settings before you start. Keep your first run short so you can see how the tool behaves on your machine.
- Open Command Prompt or PowerShell in the folder where you placed the program.
- Decide on the text you want the address to contain, such as a run of zeros after the cosmos1 prefix. Keep the pattern short for a first test.
- If you want more control, set the minimum number of letters or digits the address must include.
- Start the search and let it use all available CPU cores. Expect the time to grow as the pattern gets longer.
- When a match appears, note the address and handle the associated key material with care.
- Stop the search when you have what you need, and clear the terminal history if the session displayed sensitive output.
Pros & cons
- Free and open source, with the source code publicly available on GitHub
- Ready-made Windows build, so no compiling is needed
- Uses all CPU cores, which can speed up searches on multi-core machines
- Flexible matching by substring and by minimum counts of letters or digits
- Focused, single-purpose tool without extra features getting in the way
- Latest code update dates to May 23, 2022, more than two years ago
- Command-line only, with no graphical interface
- Search time rises steeply as patterns get longer
- Focused on Cosmos, so users of other networks need a different tool
Is Cosmosvanity safe?
Cosmosvanity produces secret key material, so treat it as a security-sensitive program. Download only from the official website or the project's GitHub repository, and compare the SHA-256 checksum or signature of the file with the value published on the release page before running it. Never type a seed phrase or private key into a third-party website, including any site that promises to check or speed up your address. Antivirus software sometimes flags tools that generate keys. Do not disable protection entirely; investigate the warning instead. Because the last code update was in May 2022, check the official Releases page for the latest version before generating keys you plan to use.
- Official source only. Download from github.com/hukkinj1/cosmosvanity. 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
Cosmosvanity sits among single-purpose vanity address generators, and each one is tied to a different network. Galvanity is a Go-based generator for Algorand addresses, Vaniton targets TON wallets, and VanitySearch is built for Bitcoin addresses. If your goal is a Cosmos address, Cosmosvanity is the one aligned with the Cosmos bech32 format and the Cosmos (ATOM) network. The main difference from the others is the target network rather than the core idea of searching for a pattern. Choose the tool that matches the chain you use, and apply the same key-handling habits to any of them.

Frequently asked questions
Yes. Cosmosvanity is free and open source, and its source code is publicly available on GitHub. Because it is a command-line program, you run it from a terminal after downloading and placing the file on your computer. Its free status does not change the need to check files before running them.
Yes. The project publishes binaries for Windows, along with builds for macOS and Linux. You download the Windows build, place the file in a folder and run it from Command Prompt or PowerShell. The installation section above walks through each step.
A vanity address is a crypto address that contains a pattern you choose, such as a specific sequence of characters near the start. Software generates candidate addresses until one matches. The pattern changes how the address looks, not how well it is protected, so the security depends on how you handle the keys.
No. Cosmosvanity is built for Cosmos (ATOM) addresses in the Cosmos bech32 format. For other networks, use a generator designed for them, such as VanitySearch for Bitcoin or Vaniton for TON. Confirm which networks any tool supports before you rely on it.
There is no fixed answer, because the time depends on the pattern, your processor and chance. Each additional character in a fixed pattern multiplies the expected number of attempts by roughly 32, since bech32 uses a 32-character alphabet. Short patterns can finish quickly, while long ones may take far longer than is practical. Start with a short pattern to test your setup.
The latest code update dates to May 23, 2022, and the latest version listed is 1.0.0. That means no newer code changes have been published since then. Look at the GitHub Releases page to see whether anything newer exists before using the tool for keys you plan to keep.
Cosmosvanity produces standard Cosmos bech32 addresses, so they follow the same format as other Cosmos addresses. Whether a particular wallet can import the underlying key depends on that wallet's own features, so confirm this before sending any funds. Testing with a small amount first is a common precaution.
Verdict
Cosmosvanity is a practical, free command-line tool for Windows users who want a Cosmos (ATOM) address with a chosen pattern. It fits developers, hobbyists and technically confident users who like to learn how vanity generation works. It is less suitable for anyone who wants a graphical interface or ongoing development, since the last update came in May 2022. Reach for it when you want a recognizable Cosmos address and you are comfortable working in a terminal.
