Installing Neo-GUI

Neo-GUI is a full-node application on the Neo blockchain. It uses Electron cross-platform technology and currently can run on Windows 10 and macOS systems.

It has these main functions:

  • Viewing and searching blockchain information
  • Basic wallet operations, including creating wallets, importing wallets, transferring transactions, etc.
  • Deploying and invoking smart contracts
  • Election and voting consensus nodes

Downloading the client#

Neo-GUI is an open source project, thus you can download the installation package of the corresponding system version on GitHub , and complete the installation according to the prompts.

  • Make sure your Windows / macOS system has .NET Core 5.0 installed.

  • When installing on the Windows system, do not install Neo-GUI under the default path C:\Program Files, or you have to run the client with the administrator privileges to connect the client to the network and download the blockchain data.

Connecting to the network#

After installation Neo-GUI connects to the N3 main net automatically.

To connect the node to test net, go to any page and click Settings in the lower left corner. Then check Testnet.

If you have already built a private chain (see Setting up private chain), you can also connect Neo-GUI to it.

  1. Find the config.json file of your private chain.

    Make sure that the address port configured in config.json SeedList can be accessed from this machine.

  2. Go to the path resources\build-neo-node under Neo-GUI installation directory and find the file config.private.json

  3. Replace the content of config.private.json with the content of config.json you found in Step 1

  4. Run Neo-GUI and go to any page.

  5. Click Settings in the lower left corner.

  6. Under Network check Privatenet.

After a while, when you see the block synchronization data displayed at the top of the main page is increasing, that indicates your client has connected to the network successfully.
