Nbai Wallet is a free, open-source wallet for Windows aimed at people who want to hold Ethereum (ETH) and ERC-20 tokens on their own computer. It is distributed as a Windows build or installer, and its source code is published on GitHub for anyone who wants to read it. Before you rely on it, note that the project has seen no code updates since July 2021, so treat it as an older, unmaintained tool.
This page explains what Nbai Wallet for Windows does, who it suits, how to install it safely, and how it compares with other wallets in the catalog. If you need a wallet that is actively developed or supports many networks, the comparison section points to alternatives worth reviewing first.
What Is Nbai Wallet and Who Is It For?
Nbai Wallet is a desktop application for Windows that lets you manage an Ethereum address and the ERC-20 tokens associated with it. Like most wallets, it does not store coins inside the program itself. Instead, it holds the cryptographic keys that prove ownership of the assets recorded on the Ethereum blockchain.
The most natural audience is someone who already holds ETH or ERC-20 tokens and wants to control the software that manages them. It also suits developers who want to study a wallet built with JavaScript and TypeScript. The codebase was scaffolded with Angular CLI 1.7.3, which is a useful clue about its age and about how much modernization it would need before serious long-term use.
If you are new to crypto, expect a learning curve. Concepts such as addresses, gas fees and token contracts are central to working with Ethereum, and a wallet only makes them easier to handle once you understand what each one does.
How Wallet Keys and Seed Phrases Work
A crypto wallet works by managing a pair of keys. The public address is what others use to send you funds, and it is safe to share. The private key is what authorizes outgoing transactions, and anyone who obtains it can move the funds without asking you.
Most wallets make private keys easier to handle by generating a seed phrase, a list of words that can recreate the keys. Writing it down correctly is the single most important habit for wallet users. If the seed phrase is lost, no support team or software update can restore access to the funds.
ERC-20 tokens work differently from ether. They are records managed by smart contracts on Ethereum, so a wallet displays them by reading contract data tied to your address. Knowing that difference helps when you check balances or troubleshoot why a token does not appear as expected.
Practical Scenarios for an Ethereum Wallet on Windows
One common scenario is a user who wants to keep a modest Ethereum balance on a personal computer rather than leaving it on a trading platform. Another is someone who receives ERC-20 tokens for a project and wants a local wallet to view them without sending everything to a third party.
Developers form a second group. They may want to read the code, test small transactions on a test setup, or learn how a browser-based wallet is structured on the desktop. The open-source license and published repository make this kind of study possible without special access.
Whatever the scenario, start small. Send a small test amount to confirm that your address, network and token contract all match before you move larger sums. Careful testing costs little and prevents most beginner mistakes.
Key features
Focus on Ethereum and ERC-20 tokens
Open-source code
Free Windows build
Supported coins
The documentation covers Ethereum (ETH) and ERC-20 tokens. If you plan to hold assets on other blockchains, check the scope carefully before moving funds, since the project's documented focus is narrow.
How to install Nbai Wallet on Windows
- 1
Download from the right place
Download only from the official website or the project's GitHub Releases page at github.com/nebulaai/nbai-wallet. Avoid mirror sites, forum attachments and file-sharing links, because modified installers are a common way to steal wallet access.
- 2
Verify the file
Calculate the SHA-256 checksum of the downloaded file and compare it with the value published with the release. If the checksum does not match, delete the file and download it again from the source before running anything.
- 3
Run the installer
Double-click the installer and follow the prompts. Keep the default install location unless you have a clear reason to change it, and decline any optional extras you did not request.
-
Create or restore your wallet
On first launch, write down the seed phrase by hand on paper and store it offline in a secure place. Do not save it as a screenshot or plain text file on the same computer.
How to use Nbai Wallet
Nbai Wallet is designed around a simple workflow: set up the wallet, confirm your address, and then work with Ethereum and ERC-20 tokens. The steps below assume you have already installed the program and recorded your seed phrase.
- Open Nbai Wallet and unlock it with the password you set during setup.
- Check that the displayed Ethereum address matches the address you saved during setup.
- Review your ETH balance and any ERC-20 tokens the wallet shows for that address.
- To receive funds, share your public address only. Confirm the network and token before sending anything to it.
- To send funds, enter the recipient address carefully and double-check the amount and network fee before confirming.
- Wait for the transaction to appear on a public Ethereum block explorer, then verify that the balance updates as expected.
- Keep a record of each transaction you send, since the wallet will not reverse a mistaken transfer.
Pros & cons
- Free to download and use
- Source code is published on GitHub for review
- Packaged Windows build avoids compiling from source
- Narrow, clear focus on Ethereum and ERC-20 tokens
- Useful as a learning project for developers studying wallet design
- No code updates have been published since July 2021
- Documented support is limited to Ethereum and ERC-20 tokens
- Building from source requires editing crypto library imports, which adds work for developers
- Codebase based on Angular CLI 1.7.3 would need significant modernization for long-term use
Is Nbai Wallet safe?
Nbai Wallet handles private keys and funds, so treat safety as a priority. Download the program only from the official website or the project's GitHub Releases page, and verify the SHA-256 checksum before running the installer. A matching checksum confirms the file was not altered in transit.
Note that the project has had no code updates since July 2021. Older software may not receive fixes for newer security issues, so the risk is higher than with an actively maintained wallet. Antivirus tools sometimes flag wallet software, and a false positive is possible, but you should never disable your protection entirely. If a warning appears, verify the file first and consider a different wallet if you remain uncertain.
Never enter your seed phrase or private key on a third-party website, in a chat or in a support form. Check the latest version on the official website before installing.
- Official source only. Download from github.com/nebulaai/nbai-wallet. 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
Nbai Wallet is a narrow tool. Its documented focus is Ethereum and ERC-20 tokens, which makes it simpler to understand but less flexible than wallets with wider scope. Cake Wallet, listed in the catalog as an open-source, non-custodial and private multi-currency wallet, covers a much broader range of assets, so it is better suited to people who hold several coins. Cake Wallet is a good comparison point.
BitPay Wallet, also known as Copay, is built around a different user group. AlphaWallet, by contrast, is a platform for programmable blockchain apps rather than a simple personal wallet. WAIaaS targets self-hosted wallet services for AI agents with EVM and Solana support, so its purpose differs entirely from Nbai Wallet's desktop focus.

Frequently asked questions
Nbai Wallet can be used with care, but its project has had no code updates since July 2021, which means it may not include recent security fixes. Download it only from the official website or GitHub Releases, verify the SHA-256 checksum, and never share your seed phrase with anyone.
Yes, Nbai Wallet is listed as free and is distributed as open-source software. You can download the Windows build or installer without paying for the program itself. Blockchain network fees still apply whenever you send transactions on Ethereum.
The documentation focuses on Ethereum (ETH) and ERC-20 tokens. Because the scope is narrow, check it before moving other assets, and consider a broader wallet if you hold coins from several different blockchains.
No, the ready-made Windows build or installer runs without those tools. Node.js, npm and similar build dependencies only matter if you compile the project from its source code yourself. Most users can skip that process entirely.
Yes, the source code is published on GitHub in the nebulaai/nbai-wallet repository. Open code means you or a security reviewer can inspect how the wallet handles keys and transactions before trusting it with funds.
If you lose your seed phrase and cannot access the wallet, no one can restore the funds for you. Neither the developers nor a support desk can recover keys from the blockchain. Keeping a secure, offline backup is the only reliable protection against this problem.
Nbai Wallet is designed for holding and transferring Ethereum and ERC-20 tokens rather than trading. Any decision to buy or sell is your own, and it carries market risk. Avoid treating a wallet as a trading tool.
Verdict
Nbai Wallet suits people who want a free, open-source Windows wallet for Ethereum and ERC-20 tokens and who are comfortable verifying software themselves. Developers who want to study a wallet's code will also find it useful. Because the project has not been updated since July 2021, it is a weaker choice for anyone who needs active maintenance or a wide range of supported assets. Compare it with actively maintained alternatives before storing significant funds.
