Vechi Wallet for Windows is a free, open-source Ethereum wallet toolkit for developers and technically confident users who want to hold their own keys. It comes with a Windows installer, but its core is a JavaScript and TypeScript library, so it suits people who are comfortable reading code and working with configuration files.
Before you install, note that the most recent code update in the public repository is dated January 21, 2024, more than two years before 2026. The project is published under the MIT license and its latest version is v6.10.0, but the code history shows no updates since early 2024. Plan for the possibility that bugs or compatibility issues will not be fixed, and read the safety section carefully before you use it with real funds.
What Is Vechi Wallet and Where Does It Fit?
The project describes itself as a complete Ethereum wallet implementation and a set of utilities written in JavaScript, with TypeScript support. In practice, it is closer to a building block than to a finished consumer app. You use it to generate keys, sign transactions and communicate with the Ethereum network from code.
That distinction matters when you compare it with desktop products. A ready-made wallet application usually gives you screens for sending, receiving and managing accounts. A toolkit gives you functions and objects that your own program calls. The Windows installer makes the software easy to put on a machine, but the real work happens in scripts and applications you write or adapt.
The documentation is hosted under a v5 path on the project site, while the latest release is listed as v6.10.0. Developers should read the release notes and compare the API they plan to use against the current version before building anything serious. Small differences in method names or defaults can cause confusing bugs if you copy older examples without checking them.
Who Is Vechi Wallet For?
The most natural audience is developers who want to add Ethereum functionality to a JavaScript or TypeScript project. A team building a test script, a small dashboard or a proof of concept can use the toolkit to generate addresses, read contract data and prepare transactions without writing cryptography from scratch.
Students and hobbyists also benefit. Working through the code is a practical way to learn how seed phrases become private keys, how HD wallets derive addresses and how JSON files store encrypted keys. Reading the source and running the test cases can teach more than a settings screen ever would.
People who simply want an app to hold a balance and send payments are a poorer fit. The toolkit does not replace a polished wallet with guided onboarding, recovery help and support channels. If you are not comfortable with terminals, configuration files and reading documentation, a dedicated end-user wallet is likely a better choice, and the comparison section below lists alternatives.
How Seed Phrases, HD Wallets and JSON Files Fit Together
A seed phrase, also called a mnemonic or recovery phrase, is a human-readable list of words that encodes a larger random number. The BIP 39 standard used here turns that phrase into a seed. Anyone who knows the words can rebuild the same wallet, which is why the phrase must stay secret and offline.
HD, or hierarchical deterministic, wallets use that seed to derive a tree of keys and addresses. One backup can therefore produce many accounts. This is convenient for privacy and organization, but it also means that a single leak exposes every derived account, so keep the seed separate from everyday devices.
JSON keystore files are a different format. They store a private key encrypted with a password, which makes them useful for moving accounts between tools. A keystore is only as safe as its password, and a weak password can be cracked offline. Understanding these three pieces helps you choose the right backup method and avoid storing secrets in plain text files on your desktop.
Key features
Client-side key storage
JSON wallet import and export
BIP 39 mnemonic and HD wallet support
Contract interaction from any ABI
Flexible node connections
ENS name support
Small, modular packages
Documentation, tests and TypeScript types
Supported coins
The project's documentation describes support for Ethereum (ETH) and the wider Ethereum ecosystem, including ENS names and smart contracts that follow standard ABI definitions. The toolkit handles keys and addresses in the formats common to Ethereum accounts, such as JSON keystores and 12-word BIP 39 phrases. It does not list other coins or networks, so treat it as an Ethereum-focused library.
How to install Vechi Wallet on Windows
- 1
Get the installer from the official source
Open the project's GitHub repository at github.com/vechibetrachvili/vechi-wallet and look for the release files on its Releases page. Download only from the official website or GitHub, and never use mirror sites or links shared in chats or messages. Save the file to a folder you control.
- 2
Verify the file before running it
Compare the SHA-256 checksum of the downloaded file with the value published alongside the release. If the release also provides a signature, verify it as well. Do not run a file whose hash does not match, even if the download appears to complete normally.
- 3
Run the setup.exe installer
Launch the setup.exe file and follow the on-screen prompts. Choose an install location you can find later and keep the default options unless you have a specific reason to change them. Close other wallet software while the installation runs to avoid confusion over file locations.
-
Confirm the version and prepare your backup
Check that the installed version matches the release you verified, and note that v6.10.0 is the latest listed version. Before you store any funds, write your seed phrase on paper and keep it offline in a secure place. Do not photograph it or save it in a cloud note.
System requirements
- Windows PC that can run the setup.exe installer
How to use Vechi Wallet
Using Vechi Wallet well is mostly about careful setup and small test runs. The steps below assume you have already installed and verified the program, and that you plan to work with it from code or a configured environment.
- Decide whether you need a new wallet or an existing one. Create a new wallet for a clean start, or import a JSON keystore if you are moving an account from another client.
- Write down the 12-word seed phrase immediately after creation. Store it offline and check each word against the original list before you rely on it.
- Choose a connection method. Pick a JSON-RPC endpoint or a provider such as INFURA, Alchemy or Etherscan, and keep the endpoint in a configuration file rather than in public code.
- Derive or load the address you plan to use. If you work with HD wallets, confirm the derivation path so you know which address matches the account you expect.
- Test with a small amount. Send a small transaction to an address you control and confirm that the balance and transaction hash appear as expected.
- If you use ENS names, resolve a name to an address and compare the result with the address you intended before sending any transaction.
- Keep a log of the version, provider and settings you used. This makes it easier to reproduce a result or troubleshoot a problem later.
These steps are simple on paper, but each one has a failure mode. A wrong derivation path or a mistyped provider URL can make a transaction go to the wrong place, so slow down and verify at each stage.
Pros & cons

- Keeps private keys on your own computer rather than on a remote service
- Supports JSON wallet import and export from several common formats
- Handles 12-word BIP 39 phrases and HD wallets in multiple languages
- Modular packages keep bundles small and dependencies focused
- Extensive documentation, maintained test cases and TypeScript definitions
- The most recent code update is dated January 21, 2024, so ongoing fixes are uncertain
- Designed mainly for developers, not for people who want a point-and-click app
- Focused on Ethereum, with no other coins or networks listed
- Documentation links point to the v5 path while the latest version is v6.10.0
- Requires comfort with code, configuration files and terminal workflows
Is Vechi Wallet safe?
Vechi Wallet handles private keys, so safety deserves more attention than usual. The latest code update in the public repository is dated January 21, 2024, which is more than two years old. That means you should expect fewer fixes and plan your own review before trusting it with significant funds.
Always download from the official source on GitHub, and verify the SHA-256 checksum or signature before running the installer. Check the latest version on the official website or repository before you install. Never enter your seed phrase, private key or keystore password on a third-party website, in a chat or in an email, even if the request looks official.
Treat any software that controls keys as a potential target. Keep your operating system updated, use a separate device for large balances if possible, and consider testing with small amounts first.
- Official source only. Download from github.com/vechibetrachvili/vechi-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
Vechi Wallet differs from most of the programs in this catalog because it is a developer toolkit rather than a finished wallet. Frame is a desktop Web3 wallet that you use as an application, while MyCrypto focuses on managing Ethereum accounts through an interface. Those tools suit people who want to click through their accounts without writing code.
Stack Wallet and Cake Wallet are open-source, multi-currency wallets aimed at everyday users who hold several assets. Vechi Wallet covers only Ethereum according to its documentation, but it gives developers direct control over keys, ABIs and provider connections. Choose it when you need to build or test something, and choose an end-user wallet when you mainly want to hold and send coins.

Frequently asked questions
Vechi Wallet is a free, open-source Ethereum wallet toolkit written in JavaScript and TypeScript. It lets developers generate keys, handle seed phrases, work with JSON wallets and interact with smart contracts from code. It is distributed under the MIT license and includes a Windows installer, although the core use case is programming rather than everyday wallet management.
Safety depends on how you install it and how you store your keys. Download the software only from the official GitHub repository, verify the SHA-256 checksum or signature, and never type your seed phrase into a third-party website. The most recent code update is dated January 2024, so review the code and test with small amounts before storing significant funds.
Yes, Vechi Wallet is free to download and use. It is released under the MIT license, which permits use, modification and redistribution under the license terms. Costs you may still face include network transaction fees on Ethereum and any paid node provider plan you choose to use for connections.
The documentation describes support for Ethereum (ETH) and the Ethereum ecosystem, including ENS names and smart contracts defined by ABI. The toolkit works with 12-word BIP 39 phrases and JSON wallet formats used by Ethereum tools. It does not list other coins, so it is not a good fit if you need a multi-currency wallet.
Download the installer from the project's GitHub Releases page, then check the SHA-256 checksum against the published value. Run the setup.exe file and follow the prompts, keeping default options unless you have a reason to change them. After installation, confirm the version and back up your seed phrase on paper before you store any funds.
The public repository shows its most recent code update on January 21, 2024, which is more than two years before 2026. The latest listed version is v6.10.0, but the history shows no recent activity. This does not guarantee that the project is abandoned, but it means you should plan for limited support and review the code yourself.
Beginners can learn from it, but it is not an easy first wallet. The toolkit is built for developers and expects familiarity with JavaScript, configuration files and blockchain concepts. A beginner who wants to understand seed phrases and addresses can benefit from running the test examples with small amounts under supervision.
Verdict
Vechi Wallet suits developers and technically confident learners who want an open-source Ethereum toolkit that keeps keys on their own machine. Its documentation, test cases and TypeScript support make it a useful base for prototypes and scripts. The main drawbacks are the code update dated January 21, 2024, and a focus on Ethereum and programming rather than everyday use. If you are not comfortable reading code, choose a finished wallet from the alternatives listed on this page instead.
