TON Dev Wallet for Windows is a free, open-source wallet built for developers working on the TON blockchain. It suits people who write and test TON applications and need to manage several keys and wallets during that work. It is less suited to everyday holders who want a simple app for buying and sending coins.
The program lets you keep multiple private keys, create several wallets for separate projects, and connect those wallets to TON-compatible websites through TonConnect. The most recent code update is dated June 13, 2026, and the project is not marked as deprecated. Because the program handles private keys, read the installation and safety sections before you download anything.
What Is a Developer-Focused TON Wallet?
In the blockchain sense, a wallet is not a container for coins. It is software that holds the private keys that prove ownership of an account and signs transactions on your behalf. Whoever controls the private key controls the funds in that account, which is why keys are the most sensitive part of any wallet.
A developer-focused wallet puts the emphasis on the workflow rather than on everyday spending. Instead of a streamlined home screen for buying and sending coins, it offers tools for managing many accounts, creating wallets for different test scenarios and connecting them to websites under development. TON Dev Wallet follows this approach, with its focus on simplifying development for the TON blockchain.
If you are new to TON development, think of the wallet as a testing instrument. You use it to sign test transactions and to check how your application responds, not as a long-term savings account.
Who Is TON Dev Wallet For?
The program is most useful for people whose daily work involves TON accounts and transactions. Typical users include:
- A developer building a dapp who needs a wallet to test login and transaction flows through TonConnect.
- A smart contract tester who wants several wallets to play the roles of sender, receiver and administrator.
- An instructor teaching TON basics who wants a separate account for each student during an exercise.
In each case, the value comes from managing several accounts side by side. A single-purpose wallet makes it harder to keep test activity separate from real activity, so creating dedicated wallets for each scenario is a practical habit.
Why Preview Transactions Before Sending Them?
Sending a transaction on a live network is final, so a mistake in a contract call or a wrong recipient can be costly. Previewing the expected result beforehand reduces that risk. TON Dev Wallet includes local transaction emulation, which shows how a transaction would play out before it is executed on TON.
For developers, emulation is most valuable during iterative testing. You can adjust a message, run it again and compare outcomes without repeatedly committing real transactions. It does not replace audits or careful code review, but it gives you a quicker feedback loop while you build.
Treat any preview as a guide rather than a guarantee. Conditions on the network can change between the preview and the moment of execution.

How to install TON Dev Wallet on Windows
- 1
Download the installer
Download only from the official website or the project's GitHub Releases page at github.com/TonDevWallet/TonDevWallet. Avoid mirrors, forum links and file-sharing sites, since a copied installer can be modified.
- 2
Verify the file
Find the SHA-256 checksum published with the release and compare it with the checksum of your download. Run a command such as certutil -hashfile on the file in Windows. If the release provides a signature, verify it as well. Do not run the file if the values do not match.
- 3
Run the installer
Open the installer and follow the on-screen prompts. Choose an install location you can find later, and keep the program updated by downloading new releases from the same official source.

Create or add your first wallet
Launch the app and create a wallet for your first test scenario. Write down the seed phrase on paper and store it somewhere safe. Never type it into a website, chat or form that asks for it.
How to use TON Dev Wallet
TON Dev Wallet is organized around accounts, so it helps to plan your setup before you start working.
- Launch the app and create a separate wallet for each scenario you plan to test, such as a deployment account and a user account.
- Add or create the private keys you need and label them clearly so you know which account is which.
- Open the TonConnect section when you want to connect a wallet to a TON-compatible website or a dapp under development.
- Approve the connection only for test sites and applications you control or trust.
- Before sending a transaction, use local transaction emulation to preview the expected result.
- Compare the preview with what your application expects, and adjust the message or parameters if the outcome differs.
- Send the transaction only after the preview matches your intent.
- Record which wallet performed each action, so your test logs stay easy to follow.
- Back up your seed phrases and keys offline after each new wallet is created.
Pros & cons
- Free to use and open source, so the code can be reviewed
- Focused on TON development rather than general-purpose spending
- Supports multiple private keys and multiple wallets in one app
- Includes TonConnect integration for testing wallet connections
- Offers local transaction emulation to preview results before sending
- Recent code update dated June 13, 2026
- Built around TON development, so it is not a general multi-chain wallet
- May feel complex for users who only want to hold and send coins
- Version 0.8.0 suggests an evolving project that may change over time
Is TON Dev Wallet safe?
Download only from the official website or the project's GitHub Releases page at github.com/TonDevWallet/TonDevWallet. Compare the SHA-256 checksum of the installer with the value published with the release, and verify the signature if one is provided. A mismatch means the file should not be run. Never enter your seed phrase or private keys on third-party websites, including sites that offer support, airdrops or upgrades. Anyone who asks for those secrets is trying to take your funds. The project was last updated on June 13, 2026, and is not marked as deprecated, but check the latest version on the official website before you install it.
- Official source only. Download from github.com/TonDevWallet/TonDevWallet. 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
Most wallets in this catalog aim at a broad audience. Coinomi and Atomic Wallet are multi-currency wallets built to hold many assets, and Trust Wallet is primarily a mobile wallet with a browser extension on desktop. Exodus combines a wallet with built-in exchange features. TON Dev Wallet takes a narrower path. It focuses on TON accounts, multiple keys and wallets for development, TonConnect testing and transaction emulation. If you need a wallet for managing a diverse portfolio, a general multi-currency option will fit better. If your work centers on building and testing for TON, TON Dev Wallet is the more targeted choice.

Frequently asked questions
Yes, TON Dev Wallet is free and open source. You can download the program from the official website or the project's GitHub Releases page. Because it is open source, developers can review the code and see how the wallet works before relying on it.
It can be used safely if you follow basic precautions. Download the installer only from the official source, verify its SHA-256 checksum, and never enter your seed phrase on third-party websites. Keep backups of your keys offline and use the wallet for test accounts whenever possible.
Yes, TON Dev Wallet supports Windows and is distributed as a Windows build or installer. Download the installer from the official website or the GitHub Releases page, verify the file, and then run it like any other Windows program.
TonConnect is a standard that lets websites and applications request a connection to a TON wallet and ask the user to approve transactions. Developers use it to build dapps that work with wallets. TON Dev Wallet includes TonConnect integration, so you can test those connections from the desktop.
No, you do not need Node.js, npm or other build tools to run the ready-made program. Those tools are used when building the software from source. If you only want to install and use the wallet, download the Windows installer and run it directly.
Yes, the wallet supports multiple private keys and lets you create multiple wallets. This is useful for separating deployment accounts, test users and experiments. Label each wallet clearly so your test activity stays organized.
Transaction emulation runs locally and shows a preview of the expected result before anything is executed on TON. A real transaction is sent to the network and cannot be undone. Use emulation to check and adjust your messages before you commit to sending them.
Verdict
TON Dev Wallet is a good fit for developers who work with the TON blockchain and need to manage several keys and wallets during testing. Its TonConnect integration and local transaction emulation support a practical workflow for building and checking dapps. It is a poor fit for people who want a simple app for everyday holding across many networks. Because it is free, open source and recently updated, it is worth evaluating if TON development is your main task. Keep your keys backed up and your setup organized.
