Komodo DeFi Framework is open-source atomic swap software built for developers who want to add peer-to-peer trading between blockchain assets to their own tools. It is an engine rather than a finished trading app, so it suits integrators, researchers and technically confident users who are comfortable working from a command line. Before you install anything, note that the project is archived: its repository is kept for historical reference, and no further updates, bug fixes or security patches are planned.
The framework moves orders and swap states between peers over the libp2p protocol. It uses Hash Time Lock Contracts so that a trade either completes for both sides or returns funds to their original owners. Windows users can run a pre-built binary from the official repository. The latest release is labeled v3.0.0-beta, so treat it as early-stage software and test it carefully.
What Is an Atomic Swap and How HTLCs Work
An atomic swap lets two parties exchange assets on different blockchains without trusting a third party to hold their coins. The word atomic means the trade is all or nothing: either both transfers complete, or neither does. Komodo DeFi Framework relies on this principle for every swap it executes.
The mechanism behind this is the Hash Time Lock Contract, or HTLC. Each side locks its funds under the same secret hash and sets a deadline. When one party reveals the secret to claim its funds, the other party learns it and can claim theirs. If the deadline passes without a claim, the locked funds return to their original owner.
Consider a simple example. Alice holds Dogecoin and wants Bitcoin, and Bob wants the opposite. Each locks their coins under the same hash, and neither can take the other's funds without also releasing their own. The swap happens peer to peer, so no exchange company holds either person's assets during the process. Understanding this flow helps you judge what can go wrong, such as a deadline that expires before the other side responds.
How Orders Travel Across the Peer-to-Peer Network
Orders in the framework are not posted to a central server. They are propagated between nodes using the libp2p networking protocol, which lets peers discover each other and share orderbook updates and swap states. Each participant sees a view of the market built from what its peers broadcast.
This design has practical consequences. A listed order is only as available as the peer behind it, so an order that looks attractive may disappear if its maker goes offline. Before relying on a quote, check that the order is still live and that the swap is progressing as expected. Prices can also differ between peers because each node sees updates at slightly different times.
For developers, the peer-to-peer design means there is no single endpoint to monitor or shut down. For traders, it means patience matters. Expect some trades to take longer than a centralized exchange fill, and plan around the confirmation times of the coins involved.
Who Komodo DeFi Framework Is Built For
The framework is best suited to developers who want to build decentralized trading tools. A team designing a DEX front end, a market-making bot or a monitoring dashboard can use its orderbook queries and swap functions as building blocks. Researchers studying cross-chain trading can also use it to observe how HTLC-based swaps behave in practice.
It is less suited to people who want a point-and-click app. Because the software is a framework and is started from a terminal, a newcomer will spend most of the learning curve on configuration and command syntax. Someone who only wants to buy and sell occasionally will likely find a finished application easier to use.
Given the archived status, the most sensible use is learning and reference work: reading the Rust source, testing swap flows on small amounts, or studying how a mature atomic swap design is structured. Treat it as a tool to understand rather than as a long-term foundation for a live product.
Key features
Trading Without a Local Native Chain
Orderbook Discovery
Taking and Making Orders
Automated Makerbot Trading
Supported coins
The documentation names Bitcoin (BTC), Dogecoin (DOGE) and Komodo as coins the framework works with. Because the framework is built to handle trading across many chains, the practical list of assets you can trade depends on the coins you configure and on whether a counterparty offers a matching order. Review the documentation in the official repository before planning any trade.
How to install Komodo DeFi Framework on Windows
- 1
Get the Windows build
Download only from the official website or the Releases page of the official GitHub repository. The project publishes pre-built release binaries for Windows, along with builds for other platforms. Avoid mirrors and file links shared on forums or chat groups.
- 2
Verify the file
Calculate the SHA-256 checksum of the downloaded archive and compare it with the value published with the release, if one is provided. You can also check a signature when one is available. If the values do not match, delete the file and download it again before going further.
- 3
Extract to a dedicated folder
Unpack the archive into its own folder, such as one named KDF at the root of your C drive. Keeping the executable and any configuration files together makes them easier to find and back up. Confirm that kdf.exe is in that folder before you start it.
-
Launch from a terminal
Open Command Prompt or PowerShell in the folder and run kdf.exe. Starting the program from a terminal lets you read startup messages and errors as they appear, which helps you troubleshoot configuration problems early.
How to use Komodo DeFi Framework
Once the framework is installed and kdf.exe is running, you work with it by sending requests to the running process and following the examples in the official documentation. The steps below outline a typical first session.
- Start kdf.exe and leave its terminal window open while you work.
- Read the documentation to confirm which coins you need, then set them up in your configuration.
- Query the orderbook for the trading pair you care about and compare the available prices.
- Buy or sell from an existing order, or create a maker order and wait for a counterparty to fill it.
- Track the swap state until it completes, and confirm that the expected funds arrive on each chain.
- Optionally, configure the makerbot with periodic price updates and Telegram alerts, then start with a very small amount to see how it behaves.
Pros & cons
- Open-source code, so the atomic swap logic can be read and reviewed
- Free to use
- HTLC-based swaps are designed so that a trade completes for both sides or funds return to their owners
- Can work with coins through Electrum servers without running a full local node for each chain
- Includes a makerbot with periodic price updates and optional Telegram alerts
- Pre-built binaries are available for Windows and several other platforms
- The project is archived, and no further updates, bug fixes or security patches are planned
- The latest release is labeled v3.0.0-beta
- Aimed at developers, so it is not a point-and-click trading app
- Trades depend on counterparties being online and willing to fill orders
- Setup and daily use require comfort with command-line tools and configuration files
Is Komodo DeFi Framework safe?
Komodo DeFi Framework handles keys and funds, so treat the download and setup with care. The project is archived and no security patches are planned, which means any vulnerability discovered later may stay unfixed. For that reason, use it only with small amounts and read the code yourself if you rely on it. Verify the SHA-256 checksum or signature before running kdf.exe, and never enter a seed phrase or private key on third-party websites or in messages from strangers. Check the latest version on the official website before you start.
- Official source only. Download from github.com/KomodoPlatform/komodo-defi-framework. 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
Several catalog entries cover similar ground, but they differ in purpose. AtomicDEX API is the closest relative: it is also an atomic swap engine, and it is listed as an archive, so review its status before choosing between them. Bisq and Bisq 2 are peer-to-peer exchanges for Bitcoin aimed at everyday traders rather than developers. ASGARDEX focuses on a wallet and DEX built around THORChain. Komodo DeFi Framework is best understood as a building block for other tools rather than a finished trading product, which makes it a better fit for developers than for people looking for a ready-made exchange.

Frequently asked questions
It can be used with care, but the project is archived and no security patches are planned, so risks may remain unfixed. Verify the SHA-256 checksum or signature before running the program, and never share a seed phrase or private key. Start with small amounts and treat the framework as a tool for testing rather than for storing significant funds.
Yes, the software is listed as free and open source. Because the code is public, you can read the Rust source in the official repository and see how the swap logic works. Free use does not remove other costs or risks, since you still manage your own keys and setup time, and you pay the network costs of the coins you trade.
No. The repository is being archived and kept for historical reference, and no further updates, bug fixes or security patches are planned. The latest labeled version is v3.0.0-beta, and the last recorded code update is dated 2026-10-07. Plan around these facts before depending on the software for anything important.
An atomic swap is a trade in which two parties exchange assets on different blockchains without trusting a third party. Hash Time Lock Contracts ensure that either both transfers complete or the locked funds return to their original owners after a deadline. This removes the need for a centralized exchange to hold customer coins during the trade.
Yes. Pre-built release binaries are available for Windows, and the program starts when you run kdf.exe. Because it is launched from a terminal, you will work through Command Prompt or PowerShell rather than a graphical wallet. The project also publishes builds for macOS, Linux, Android, iOS and Docker.
The documentation names Bitcoin (BTC), Dogecoin (DOGE) and Komodo. The assets you can actually trade depend on the coins you configure and on whether a counterparty has a matching order. Check the current documentation in the official repository before planning any trade.
Yes. The framework includes a makerbot that can be configured for automated trading with periodic price updates, and it can send optional Telegram alerts. Automated strategies still need testing on small amounts, because the bot acts on whatever settings you provide, and no configuration guarantees a profit.
Verdict
Komodo DeFi Framework is serious atomic swap engineering for developers, integrators and researchers who want to study or build peer-to-peer cross-chain trading on Windows. It is free and open source, and its HTLC design keeps trades all or nothing. However, the project is archived, the latest release is beta, and no security patches are planned, so it is a poor foundation for production funds. Use it to learn, test and prototype, and keep amounts small.
