Kaspa Miner (tmrlvi) is a free, open-source GPU miner for Windows and Linux, aimed at people who want to mine Kaspa (KAS) with the kHeavyHash algorithm. It is written in Rust and ships as a precompiled Windows build for its GPU version, so you can run it without setting up a development environment.
Before you start, know the project status. The last code update is dated August 2022, which is more than two years ago, so this miner should be treated as unmaintained. It may still run on some setups, but do not expect fixes for newer network changes or hardware. Readers who want a more recently developed option will find alternatives listed further down this page.
What Is Kaspa Miner?
Kaspa Miner is a program that takes work from the Kaspa network, runs the kHeavyHash calculations on your graphics card, and submits the results back. Each valid result is a hash attempt, and the total number of attempts per second is called your hashrate. A higher hashrate generally means more chances to find a block, but the rate alone does not tell you what you will earn.
The miner does not hold coins itself. You provide a wallet address and, in most setups, a mining pool address, and rewards are sent to the wallet you configured. Keeping those addresses accurate is the single most important part of configuration, because a typo can send rewards to the wrong place.
Who Is Kaspa Miner For?
This miner suits people who already have a GPU, understand wallets and pools, and want an open-source tool they can inspect. It is a good fit for tinkerers who like reading code and for users who run Linux alongside Windows.
It is less suitable for complete beginners. Because the project is no longer maintained and the interface is a command-line tool, first-time miners may find the setup frustrating. In that case, a newer, actively developed program listed in the alternatives section may be easier to start with.
How GPU Mining Works in Practice
Imagine a gamer with a single graphics card who wants to run a miner overnight. They would first measure the hashrate and the card temperature during the first hour. If the temperature climbs too high, they might lower the power limit in their GPU software, which usually reduces both heat and power draw.
Power consumption matters as much as hashrate. Electricity costs, driver updates and cooling all change the final picture, and none of them are fixed. Tracking these numbers over a few days gives a clearer idea of whether the setup makes sense for your own situation.
Key features
GPU mining for kHeavyHash
Windows and Linux builds
Adjustable developer fee
Open source in Rust
Supported coins
The documentation names Kaspa (KAS) as the network this miner works with, and it uses the kHeavyHash algorithm. It is not a general-purpose tool for other coins, so check that your target is Kaspa before you configure anything.
How to install Kaspa Miner (tmrlvi) on Windows
- 1
Open the official release page
Go to the Releases page of the official GitHub repository for tmrlvi's Kaspa Miner. Download only from the official website or its GitHub repository, and choose the Windows package labeled for the GPU version. The current release name is kaspa-miner-v0.2.1-GPU-0.1.
- 2
Extract the archive
Unzip the downloaded file into a dedicated folder, such as C:\Miners\kaspa-miner. Keeping miners in their own folder makes it easier to manage updates and to add a targeted antivirus exception later.
- 3
Check the file before running it
If the release page publishes a SHA-256 checksum, compare it with the hash of your file. In PowerShell, run Get-FileHash on the downloaded file and match the output. Do not run the file if the hashes differ.
-
Avoid cargo install for this version
Installing with cargo install is not supported for the latest version, so use the precompiled binary instead. Building from source is a separate task that is not needed for a standard Windows setup.
System requirements
- Windows PC with a GPU, since this is the GPU version of the miner
- Command Prompt or PowerShell to launch the program with its options
How to use Kaspa Miner (tmrlvi)
Running the miner is done from the command line. The steps below assume you have already extracted the Windows package and checked its hash.
- Open Command Prompt or PowerShell in the folder where the miner is stored.
- Enter the pool or node address and your wallet address exactly as your pool or node provider lists them.
- Set the devfund percentage with the devfund-percent option if you want to change the default. The minimum in precompiled binaries is 2 percent, and the default is 2.
- Start the miner and watch the first few minutes of output for errors, rejected work or unusual temperature readings.
- Stop the miner with Ctrl+C when you finish, and review the hashrate and temperature logs before running it again.
For the first session, keep it short and watch the output closely. Small configuration mistakes are much easier to spot early.
Pros & cons
- Free and open source, with public code on GitHub
- Windows GPU build and Linux binaries available from the same release page
- Adjustable devfund option with a clearly stated minimum
- Written in Rust, which makes the code approachable for developers who want to audit it
- Not maintained since August 2022, so fixes for newer conditions are unlikely
- Covers only Kaspa (KAS) and the kHeavyHash algorithm
- Precompiled binaries enforce a 2 percent minimum devfund
- cargo install is not supported for the latest version
- Command-line setup can be difficult for beginners
Is Kaspa Miner (tmrlvi) safe?
Mining software needs extra caution because it runs heavy workloads on your hardware and handles your wallet address. Download only from the official website or the project's GitHub Releases page. After downloading, verify the SHA-256 checksum or signature when the release provides one, and compare it with the hash you calculate locally.
Antivirus tools often flag mining software as suspicious, even when the program is clean. If that happens, add an exception for the miner's folder rather than disabling your protection entirely. Never enter a seed phrase into a miner or on any third-party website, because a miner only needs a receiving address. Since the project has not been updated since August 2022, check the latest version on the official website before you install anything.
- Official source only. Download from github.com/tmrlvi/kaspa-miner. 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
Tmrlvi's Kaspa Miner competes with another kHeavyHash miner, Kaspa Miner (elichai), which targets the same network. Choosing between them comes down to which codebase and release history you trust, so compare their release pages before you commit.
Multi-algorithm GPU miners such as GMiner and lolMiner cover a wider range of hardware and algorithms. lolMiner supports NVIDIA, AMD and Intel GPUs, while TeamRedMiner focuses on AMD cards. If you want broader hardware support and an actively developed tool, those options may fit better than a single-network miner. NBMiner and T-Rex Miner are also GPU miners, but their development has stopped.

Frequently asked questions
It can be, but only if you download it from the official GitHub Releases page and verify the file. Compare the SHA-256 checksum with the published value when available. Because mining software is often flagged by antivirus tools, check the file before adding any exception.
Yes, the program is free and open source. The source code is public on GitHub, so you can read it or build it yourself. Note that the miner sends a developer fee of at least 2 percent of blocks in the precompiled binaries.
Yes, the project lists Linux among its supported platforms and publishes binaries for it. Linux users can download the file from the same release page used for Windows. Check which package matches your system before running it.
The devfund percentage is the share of blocks the miner sends to the developer fund. The default is 2 percent, and the precompiled binaries use a minimum of 2 percent following a community decision. You can adjust it with the devfund-percent option.
No, installing with cargo install is not supported for the latest version. Use the precompiled Windows package from the release page instead. This avoids the build tools and dependencies that a source build would require.
The last code update is dated August 2022, so the project should be considered unmaintained. It may still run, but you should not expect fixes for new network changes or hardware. Compare alternatives if you need active development.
The documentation names Kaspa (KAS) as the supported network. The miner uses the kHeavyHash algorithm, so it is not a general-purpose tool for other coins. Confirm that your target matches before configuring it.
Verdict
Kaspa Miner by tmrlvi suits experienced users who want a free, open-source GPU miner for Kaspa and who are comfortable with a command-line setup. Its devfund rules and Windows and Linux builds are clear, and its code is public. The main drawback is the lack of updates since August 2022, which makes it a weaker choice for anyone who needs current hardware support. If you are a beginner or need active development, consider the alternatives described above.
