9C Launcher is a free, open source desktop application that starts, updates and manages the Nine Chronicles game. It is aimed at players who want one place to keep the game current, manage their private keys and handle NCG transfers without juggling separate tools. Because it touches wallet keys, it is worth reading the safety notes before you install it.
The launcher is written in TypeScript and built with Electron and React, with GraphQL handling its data layer. Its project is still actively maintained, with the latest version listed as 2.8.8 and recent code updates on GitHub. Windows builds are published alongside macOS and Linux, so the same tool is available across most desktop systems.
What Is 9C Launcher and Who Is It For?
9C Launcher is a bridge between the Nine Chronicles game client and the blockchain account that holds your in-game assets. Rather than running the game and a wallet separately, you open one program that handles both.
It suits players who already play Nine Chronicles and want fewer moving parts. It is less useful if you only want a general-purpose crypto wallet, since its wallet features are centered on NCG and WNCG within the game ecosystem.
How the Launcher Connects Game and Blockchain
The launcher sits between the game and the network. When you start the game, it checks for updates, selects a suitable RPC server and provides the account that signs transactions. The game then reads and writes data through that connection.
This arrangement means that network choice happens automatically. Players who previously had to edit configuration files by hand may find the flow considerably simpler.
Common Scenarios for Players and Developers
A typical player installs the launcher, creates or imports a key, keeps the game updated and occasionally moves NCG between addresses. Each of these tasks takes place in one window.
Developers and testers use the same codebase in a different way. The repository includes scripts for editing the configuration inside a packaged Windows.zip, which helps when preparing custom builds for test servers. Developers also rely on the Electron development workflow: changes to the renderer process reload quickly, while changes to the main process require restarting Electron.
Understanding Private Keys and Web3 Secret Storage
A private key is the secret number that proves ownership of a blockchain address. Whoever holds it can sign transactions, so it must be protected like a password to a bank account.
The Web3 Secret Storage format encrypts the key with a password you choose, producing a keystore file. The file is useless without that password, which is why you should store the password separately and keep backups in a secure place.

How to install 9C Launcher on Windows
- 1
Download the Official Package
Download only from the official website or the GitHub Releases page of the planetarium/9c-launcher project. Choose the Windows package and save it to a folder you control.
- 2
Verify the File
Check the SHA-256 checksum or signature against the value published with the release. A mismatch means the file may be corrupted or altered, and you should download it again from the official source.
- 3
Extract and Install
Unpack the Windows archive to a folder with a clear name. If you are a standard user, avoid system-protected directories such as Program Files, so updates can write files without elevated permissions.
- 4
Run the Launcher
Start the launcher executable. On first run, it will check for the latest game build and prepare its configuration before you can play.
-
Create or Import Your Key
Create a new key inside the launcher or import an existing one. Store the encryption password and a backup of the keystore file offline before you deposit any NCG.
How to use 9C Launcher
Once the launcher is installed and your key is set up, the day-to-day workflow is short. Most of the work is handled automatically, and you only need to act when you want to change your wallet state or switch release channels.
- Open 9C Launcher and let it check for updates before starting the game.
- Select the release channel you want, typically the stable one for regular play.
- Start the game from the launcher so it can pick a suitable RPC server.
- Open the wallet section to review your address and NCG balance.
- To send NCG, enter the recipient address and amount, then confirm the transaction carefully.
- To swap NCG to WNCG, use the swap function in the wallet and check the resulting amount before confirming.
- Keep your keystore file and password backed up after any change to your key settings.
Pros & cons
- Free and open source, so the code can be reviewed publicly
- Handles game updates and wallet functions in one application
- Automatically selects an RPC server for your network
- Encrypts keys using the Web3 Secret Storage format
- Available for Windows, macOS and Linux
- Its wallet features are focused on NCG and WNCG rather than a broad range of assets
- Documentation lists Ethereum as the only named network, so multi-chain use is limited
- Wallet functions involve real value, so mistakes can be costly
- Developer setup involves several steps and environment variables
Is 9C Launcher safe?
9C Launcher manages private keys and transfers value, so treat it with the same care as any crypto wallet. Download it only from the official GitHub repository or its Releases page, and verify the SHA-256 checksum or signature before running the file. Do not download copies from third-party sites, even if they look official.
Never type your seed or private key into a website, chat or email, and be wary of anyone who asks for it. Store the keystore file and its password in separate locations, ideally offline. Antivirus software sometimes flags launchers and packaged games as suspicious. If that happens, check the file's hash and source first, and avoid turning off your protection entirely.
- Official source only. Download from github.com/planetarium/9c-launcher. 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
9C Launcher differs from the other programs in this catalog mainly in scope. MEV Boost is middleware for Ethereum block building, aimed at validators and infrastructure operators rather than end users. Trueblocks Core focuses on reading and indexing blockchain data, which suits analysts and developers. Dumplings is a tool for analyzing CoinJoin transactions, serving a privacy-research audience.
None of these replace a game launcher. If you want to play Nine Chronicles and manage the account behind it, 9C Launcher covers that job directly. Its strength is the combination of game management and key handling in one package, rather than deep technical analysis or network-level tooling.

Yes, the project publishes Windows builds alongside macOS and Linux. The Windows version is distributed as a packed archive that you extract and run. Check the Releases page for the build that matches your system.
It can be, if you download it from the official source and verify the checksum or signature. The launcher encrypts keys using the Web3 Secret Storage format. Keep your password and keystore backups separate, and never share your private key.
Yes. The launcher lets you import a raw secp256k1 private key or scan one from a QR code. Once imported, the key is encrypted with a password you set, so store that password safely.
Open the wallet section, enter the recipient address and the amount of NCG you want to send, then review the details before confirming. Double-check the address, since blockchain transactions generally cannot be reversed.
NCG is the native in-game currency of Nine Chronicles. WNCG is a wrapped version that can be used on the Ethereum network. The launcher lets you swap between them, so check the resulting amount before you confirm.
The launcher is published for Windows, macOS and Linux. Choose the package that matches your system from the official Releases page, and verify it before running.
No. Playing the game and managing your key or NCG only requires the launcher interface. Coding knowledge is only needed if you plan to modify the source code or build custom packages.
Verdict
9C Launcher is a practical choice for Nine Chronicles players who want the game, updates and NCG wallet in a single free application. It is open source, supports multiple platforms and handles key encryption in a recognized format. Its wallet scope is narrow, so it is not a general-purpose wallet. Treat key security as your own responsibility, and check the official releases for the latest version before installing.
