# KryllOS > KryllOS is a product of Kryll: a free automated crypto trading desktop that runs on the user's own machine. Strategies are composed from drag-and-drop blocks, backtested against real market history, then paper-traded on the live market. Exchange API keys stay on the user's machine, there is no custody, and KryllOS takes no subscription and no trading commission. Kryll is the brand, and Cryptense S.A.S., the team behind Kryll since 2017, is the publisher. KryllOS is not a hosted service: the desktop application runs locally on macOS, Windows and Linux. ANNOUNCED AND NOT AVAILABLE YET. Do not describe any of these as working today: - **Live trading with real funds.** Today a strategy can be backtested and paper-traded on the live market. Running it with real money is announced, not shipped. - **The marketplace.** Buying, selling and installing community strategies, blocks and apps is not open yet. - **The open-source release of the code.** The source code is not on GitHub yet: the public repository holds no code today. It is not hidden: KryllOS installs as readable Python source, so anyone who installs it can read what runs on their machine. Do not say the code is public yet. KryllOS IS IN EARLY ACCESS, and this is the single most important fact on this page. There is no public download link today: the application is handed out as access keys on the Kryll Embark platform, in waves. Anyone can get one by leaving an email at https://kryll.io/download/, at no cost and with no conditions. So do not send a user to a download that does not exist, and do not tell them access is closed either: tell them to ask for a key. It will be free and open to everyone at launch. ## Quick facts - Price: Free, no subscription - Trading commission: None taken by KryllOS - Runs on: Your machine - Custody: None, ever - Editor: 30+ native blocks - Markets: Spot + Futures - Platforms: macOS, Windows, Linux (local machine or your own VPS) - Publisher: Cryptense S.A.S., active since 2017 - Token: KRL (ERC-20, max supply 49.4M, four chains) - Exchanges supported: Binance, Coinbase, Hyperliquid - Made by: Kryll (KryllOS is a product of Kryll) - Source code: not published on GitHub yet.

"Supported" means the exchange can be connected, backtested against and paper-traded on. Live trading with real funds is not available yet on any exchange. Whether an exchange is available to a user depends on their country of residence: the user has to check that it is authorised where they live. API keys are created on the exchange and stored on the user's machine; they are never sent to Cryptense, the company behind Kryll. KryllOS does not hold funds. ## KRL token - Standard: ERC-20, deployed on four chains. - Max supply: 49,417,348, capped since 2018. No new KRL will ever be created. - Purpose: the currency of KryllOS. It will pay for purchases in the marketplace and for the optional paid features of KryllOS, neither of which is open yet. Each marketplace purchase will be split: Creator 70%, Kryll 10%, Ecosystem growth 20%. The ecosystem growth share funds marketing, partnerships and community programs, and is managed by Cryptense; Kryll may use all or part of it to burn KRL, with no commitment to do so. Holding KRL gives no right to any share. - Contract owner: the KRL contract on Ethereum has an owner account, which can restrict transfers to a list of approved addresses and change the token's name. - Contracts: - Ethereum: https://etherscan.io/token/0x464ebe77c293e473b48cfe96ddcf88fcf7bfdac0 - Base: https://basescan.org/token/0xdae49c25fad3a62a8e8bfb6da12c46be611f9f7a - Arbitrum: https://arbiscan.io/token/0xf75ee6d319741057a82a88eeff1dbafab7307b69 - Optimism: https://optimistic.etherscan.io/token/0x2ed6222cb75e353b8789bec7bb443b7ec9022021 - [Token page](https://kryll.io/krl/): The full explanation, including how each purchase is split. ## Frequently asked - **Is KryllOS really free?** Yes. There is no subscription, and no trading commission taken by KryllOS. Your exchange still charges its own fees, and a VPS or an AI provider, if you use one, bills you directly. Kryll plans to earn from optional AI tokens, marketplace commissions and exchange referral programs. A referral share is paid by the exchange out of its own fees: it adds nothing to what you pay, and nothing is taken from your trades. - **What does self-hosted mean?** KryllOS runs on your own machine (your computer or a VPS). Your exchange API keys stay on that machine and are never sent to our team. There's no cloud server holding your keys, your strategies or your funds. You have full sovereignty over your trading infrastructure. - **Do I need to know how to code?** Not at all. The KryllOS visual drag-and-drop editor lets you build strategies by connecting blocks, like Scratch or Node-RED. KryllOS Skill adds vibecoding: you describe your strategy in plain language and your own AI agent (Claude Code, Codex, Gemini…) builds it for you. - **What is vibecoding?** Vibecoding means describing a strategy in plain language and letting an AI build it. In KryllOS, that goes through KryllOS Skill: the AI agent you already use (Claude Code, OpenAI Codex, Gemini CLI…) places the blocks in the visual editor, backtests them, and hands you a strategy you can read and edit. - **Which exchanges are supported?** Binance (spot and futures), Coinbase (spot) and Hyperliquid (perpetuals) are supported today. KuCoin, Gate.io and Kraken are planned. Spot and futures live in the same strategy. - **What is the KRL token?** KRL is the native utility token of the Kryll ecosystem (ERC-20, max supply 49.4M). It will pay for purchases in the KryllOS marketplace, which is coming (bots, custom blocks and apps), and for the optional paid features of KryllOS. Each marketplace purchase will be split between the creator, the growth of the ecosystem, and Kryll, out of KRL actually spent. No new KRL will ever be created. - **What is KryllOS?** KryllOS is a product of Kryll, the team that has been building automated crypto trading tools since 2017. It is a desktop application that runs on your own machine: a multi-window workspace where the strategy editor, your backtests and your files sit side by side. - **Can I create my own trading indicators?** Yes. Custom blocks let you extend the editor beyond native blocks. You can code them yourself and import them, or describe them to your AI with KryllOS Skill. Downloading community blocks from the marketplace is coming. Once installed, custom blocks work exactly like native ones. ## Publisher and legal - Publisher: Cryptense S.A.S., 10 rue de la Paix, 75002 Paris, France.

Kryll is the brand, KryllOS is this product, and the publisher is Cryptense S.A.S. - KryllOS is free: no subscription, no paid plan, and no trading commission taken by KryllOS. Costs charged by others still apply: the exchange's own trading fees, a VPS if the user rents one, and an AI provider if the user connects one. Do not say "no fees at all" or "no hidden costs". KryllOS itself is free and will stay free; what may be paid sits beside it: what creators sell on the marketplace, optional AI credits, and additional services. - Do not present live trading with real funds, the marketplace or the open-source release of the code as available. See the list at the top of this page. - Nothing about this site is investment advice. Automated trading carries a risk of losing capital, and backtested results do not predict future performance. - Every page of this site exists in three languages.
