Komodo is a vast open-source ecosystem. We describe Komodo as a "workshop" because it is a place where developers can build technologies and push the boundaries of blockchain innovation.

Komodo Core Technologies

Komodo AtomicDEX API

Komodo AtomicDEX API is the underlying technology that powers secure, peer-to-peer atomic swaps. It is a complete suite of open-source blockchain development tools, which includes an atomic swap engine (backend/core), DEX feature set, and APIs. Komodo AtomicDEX API provides developers with access to the blockchain industry’s widest cross-chain and cross-protocol support.

Komodo AtomicDEX API facilitates the trustless, secure exchange of digital assets across multiple blockchain networks. Both UTXO-based and account-based networks are supported. Any asset that supports time-locked or hash-locked payments can be integrated.

Bitcoin, Ethereum and ERC-20 tokens, and Litecoin are just a few examples of digital assets that are already supported. Komodo AtomicDEX API is both asset-agnostic and protocol-agnostic, meaning developers can continuously expand support to new protocols.

Developers, as well as enterprises that want to partner with Komodo, use Komodo AtomicDEX API to build non-custodial multi-chain wallets, DEXs, and other powerful financial applications. AtomicDEX is the first set of end-user applications built on top of Komodo AtomicDEX API, showcasing the capabilities of this open source technology.


AtomicDEX is a secure cryptocurrency wallet with an integrated atomic swap DEX rolled into one application. Store your digital assets and make cross-chain swaps without a middleman and with minimal fees.

Unlike most DEXs, AtomicDEX doesn’t limit trading to a single blockchain protocol. AtomicDEX offers the widest cross-chain and cross-protocol support in the entire blockchain industry. It’s easy to trade BTC, ETH, ERC-20 tokens, KMD, and hundreds of other digital assets natively from dozens of blockchains — no proxy tokens required. AtomicDEX is the first end-user application built on Komodo AtomicDEX API, which is a suite of blockchain development tools that can be used to build a wide array of robust financial applications.

Our mission is to drive the widest cross-protocol support in the industry. The AtomicDEX swap protocol facilitates the trustless, secure exchange of digital assets across multiple blockchains, both UTXO-based and account-based. We are adding new assets with each release.

Trustless — Trade without a middleman. No exchange deposits or withdrawals are required.

Cross-Protocol — Works across blockchain protocols. Swap BTC, ETH, XTZ, and more directly from your wallet.

Low Fees — Market makers don't pay any fees. Takers pay only ~0.13% (1/77 of the transaction).

Efficient — Robust market-making solutions and a unified liquidity pool ensure order books operate efficiently.

Delayed Proof of Work (dPoW)

Komodo’s uses a multi-chain architecture, which means there are no network fees and each chain has enhanced scalability. Each chain has its own coin and all transactions can be made in that coin.

Notary Nodes are 64 dedicated servers that are elected annually by the Komodo community. They are responsible for running delayed Proof of Work (dPoW) — a security mechanism that recycles the giant hash rate of the Litecoin network through a series of cross-chain notarizations.

Komodo’s own blockchain network is secured by dPoW. Available to both PoW and PoS independent chains built on Komodo technology as well as UTXO-based chains not built on Komodo technology, every dPoW-protected blockchain’s decentralized network validates each transaction and approves dPoW notarizations. dPoW has successfully defended against real 51% attack attempts and currently secures over 30 production blockchains, protecting several hundred million dollars in value. Annual fees are marginal compared to the level of security provided.

Komodo Daemon + Komodo Chain Composer

Komodo's multi-chain architecture enables anyone to launch an independent, customized blockchain (called a smart chain), which gets its own native coin. Each smart chain can set its coin name, consensus rules, mining and/or staking rewards, block times, and other features. Once you have confirmed these configurations, it takes less than 60 seconds to generate your chain and its native coin.

Projects have the option to secure their chains with Komodo’s delayed Proof of Work (dPoW), a second layer consensus mechanism that recycles the hash rate of the Litecoin network to provide optimized 51% security. The Komodo blockchain protocol uses a multi-chain architecture, which means any chain created on Komodo Chain Composer has built-in scalability and zero gas fees. Transaction costs are always paid in your chain’s native coin.

There are two options for creating smart chains: 1. Komodo Daemon (supports smart chain creation from the command-line interface) 2. Komodo Chain Composer (supports smart chain creation from a GUI).

Komodo Custom Contracts

Komodo Custom Contracts is a set of Turing complete smart contracts that provides customized features for chains built on Komodo Chain Composer. Examples of solutions that can be created with this technology include fixed-supply tokens, stablecoins, micropayment channels, and oracles.

Each use of Komodo Custom Contracts only requires a single transaction fee, paid in your chain’s native coin — no gas fees required. Experienced C and C++ developers can even write their own custom smart contracts needed to build more advanced blockchain-based games, dApps, and software.
