Hubii Core is a free, open-source desktop application for managing Ethereum wallets. It is built for people who want to keep control of their own private keys instead of leaving funds on a platform, and for Ethereum users who hold ETH and ERC-20 tokens across several addresses and want them in one place. The current release is v1.4.1, and the project lists Windows alongside macOS and Linux.
Read this before you install. The project has had no code updates since September 2020, so it has not kept pace with later changes in the Ethereum ecosystem or in wallet security practices. It can still be useful for studying how a self-custody wallet is designed, but treat it as an older tool. The safety section explains how to reduce the risk of using it, and the alternatives section points to other Ethereum software in this catalog.
What Is Hubii Core and How Is It Built?
Hubii Core is a desktop program, which means it runs on your computer rather than in a browser tab. It is built with Electron, a framework that lets developers create desktop applications using web technologies such as JavaScript. That choice is why one codebase can target Windows, macOS and Linux.
The interface relies on React for building screens, Redux for keeping track of application state such as balances and pending actions, and styled-components for styling. The architecture was heavily influenced by react-boilerplate, a popular starter template for React projects. The project's repository includes documentation that explains these design decisions in more detail.
For a regular user, this means the app feels like a native program with windows, menus and notifications, while the code underneath follows patterns that web developers will recognize. It also means that keeping the app working on new operating system versions depends on the maintainers releasing new builds, which is why the project's update history matters so much.
Who Hubii Core Is For
Hubii Core suits a few specific kinds of users. Knowing where you fit helps you decide whether the app is worth the risks described later in this page.
- An Ethereum holder who wants to move ETH and tokens off an exchange and into a wallet they control.
- A person who keeps funds in several addresses for savings, trading or testing, and wants one desktop window to see all of them.
- A Ledger or Trezor owner who prefers a desktop interface to a browser-based wallet for managing balances.
- A developer or student who wants to read the code of an Electron and React wallet to see how the pieces fit together.
The app is less suited to someone who only holds Bitcoin, who needs assets from many blockchains, or who expects regular security updates. If you are new to crypto, it helps to practice with a small amount and learn how fees and addresses work before moving significant funds.
How Do ERC-20 Tokens Work on Ethereum?
ERC-20 is a common standard for fungible tokens on Ethereum. Tokens that follow it share the same basic functions for transfers and balance checks, so wallets can display many different tokens using one set of rules. Each token is typically managed by its own smart contract, which is a small program stored on the Ethereum network.
This matters in practice because sending a token is not the same as sending ETH. A token transfer is a call to the token's contract, and it still needs ETH to pay the network fee, often called gas. Users who hold only tokens and no ETH may find that they cannot make a transfer until they add some ETH.
Another point to keep in mind is that a wallet shows balances according to the contracts it knows about. If you receive a token you do not recognize, verify the contract address on a public block explorer before interacting with it. Being able to see a token in your wallet does not mean the token is legitimate or worth anything.

How to install Hubii Core on Windows
- 1
Download Hubii Core for Windows
Go to the official website or the project's GitHub Releases page and locate the Windows build for version v1.4.1. Download only from the official website or the official GitHub repository, and avoid mirrors or files shared through forums and chat groups. Save the installer to a folder you can easily find.
- 2
Verify the file
If the release page publishes a SHA-256 checksum or a signature, compare it with your file before running anything. In Windows PowerShell, you can run Get-FileHash followed by the file path and compare the output with the published value. A mismatch means the file may have been altered, and you should not install it.
- 3
Run the installer
Double-click the installer and follow the on-screen prompts. Windows may show a warning for software from an unrecognized publisher, so take that warning seriously and rely on the hash check you already completed. Choose an install location you control and finish the setup.
-
Create or import a wallet
On first launch, create a new wallet or import an existing one. If you create a wallet, write down the recovery phrase on paper and store it offline. Do not take a screenshot or paste the phrase into a note-taking app, because those copies can be synced or exposed.
System requirements
- Windows 7 or later, 64-bit edition only
- A Ledger or Trezor device is optional and only needed if you want hardware wallet signing
How to use Hubii Core
Once the app is installed, the basic workflow is straightforward. Most of the work happens on the wallet screen, where you can see balances and choose which address to use for each transfer.
- Open Hubii Core and select the wallet you want to use.
- If you use a hardware wallet, plug in your Ledger or Trezor, unlock it, and select the matching account in the app.
- Add or select the addresses you want to manage, and give them clear names so you can tell them apart later.
- To send ETH or a token, open the send screen, paste the recipient's Ethereum address, and enter the amount.
- Check the network fee shown before you confirm. Keep enough ETH in the account to cover gas for token transfers.
- Review the full transaction, including the first and last characters of the recipient address, before approving it.
- If you use a hardware wallet, confirm the transaction on the device screen as well.
- After sending, copy the transaction hash and check its status on a public Ethereum block explorer.
To receive funds, copy the address from the receive screen and share it with the sender. Send a small test amount first, so you can confirm that the address and network are correct before moving larger balances.
Pros & cons
- Free and open source, so the code can be inspected on GitHub
- Supports Ledger and Trezor hardware wallets
- Lets you manage several wallets and addresses in one desktop app
- Keeps private keys under your own control rather than with a third party
- Runs on Windows, macOS and Linux from the same project
- No code updates since 2020, so bugs and compatibility issues may remain unfixed
- Focused on Ethereum and ERC-20 tokens rather than many networks
- The nahmii instant payment feature is still marked as work in progress
- Windows support is limited to 64-bit systems
- Less suitable for beginners who expect active help or frequent releases
Is Hubii Core safe?
Hubii Core is a wallet that handles private keys and funds, and it has had no code updates since September 2020. Treat it as an unmaintained program and weigh that risk before storing significant amounts in it. Get the installer only from the project's official website or its GitHub Releases page, and compare the file's SHA-256 checksum or signature with the value the project publishes. If no checksum or signature is available, be more cautious and consider a maintained alternative. Never type your seed phrase into a website, app or support chat outside the software itself, and never share it with anyone who contacts you claiming to be support. Using a hardware wallet and starting with small test amounts both reduce exposure. For the latest version, check the official website before installing.
- Official source only. Download from github.com/hubiinetwork/hubii-core. 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
Hubii Core sits in the same catalog category as node and client software, but it works differently. Geth, the official Go implementation of the Ethereum protocol, and Nethermind, a .NET execution client, handle the network connection that keeps a full node in sync. Erigon is positioned as a performance-focused Ethereum client, and Nimbus as a lightweight consensus client. Hubii Core does not run a node; it is a desktop wallet for sending, receiving and holding assets, with hardware wallet support. If you want to run infrastructure, look at the clients. If you want a desktop wallet for ETH and ERC-20 tokens, Hubii Core is the closer match, provided you accept that it has not been updated in years.

Frequently asked questions
Yes. Hubii Core is free and open source, so you can download it without paying a license fee and read its code on GitHub. Free does not mean risk-free, though. Because the project has not been updated since 2020, verify the installer before running it and start with small amounts. Pairing the app with a Ledger or Trezor adds a meaningful layer of protection.
It can be used with care, but it is not a low-risk choice. The code is open for inspection, yet the project has been inactive for years, so issues discovered after 2020 may remain unfixed. Reduce your exposure by downloading from official sources, checking the file hash, using a hardware wallet, and keeping only the funds you are prepared to manage carefully.
The project lists Windows 7 and later as supported, but only in the 64-bit edition. Windows 10 and Windows 11 fall within that range, so they should be covered. Because the software has not received updates since 2020, compatibility with newer system changes is not guaranteed. Test with a small transaction before relying on it.
Hubii Core focuses on Ethereum (ETH) and ERC-20 tokens. You can send and receive these assets from one desktop application and manage several addresses together. The app is not designed for Bitcoin or other blockchains, so you will need a different wallet for those coins.
Yes. The app supports Ledger hardware wallets, including the Ledger Nano S, and Trezor devices. Connecting a hardware wallet lets you keep private keys on the device while managing transactions from the desktop. Update your device firmware using the manufacturer's own tools, not through the desktop app.
nahmii is a feature the project lists for instant payments and trades. It is marked as work in progress, which means it should not be treated as a finished part of the app. Since the code has not changed since 2020, do not plan any payments or trades around it.
Open the send screen, paste the recipient's Ethereum address, enter the amount, and review the network fee before confirming. Check the first and last characters of the address, because malware can swap copied addresses. If you use a hardware wallet, confirm the transaction on the device screen too. The how-to section above lists the full steps.
Verdict
Hubii Core is a reasonable choice for someone who already understands self-custody, wants a free Windows desktop interface for Ethereum and ERC-20 tokens, and prefers to pair the software with a Ledger or Trezor. It is less suitable for beginners who want active support, regular security patches or support for many blockchains. Given its age, use small amounts, verify every download, and keep your recovery phrase offline. Before choosing a wallet, compare it with the maintained Ethereum software listed in this catalog.
