Sentinel CLI is a free, open source command line tool for working with Sentinel Blockchain from a terminal window. It is aimed at developers and technically minded Windows users who prefer typing commands to clicking through graphical menus, especially when they want to repeat or script the same task.
The project is published under the Apache-2.0 license, written in Go, and currently at version 0.3.2. That version number points to an early release, so expect the command set to change over time. This page explains what the tool does, how to install it with winget, how to approach safety, and how it compares with other Web3 development tools.
What Is Sentinel Blockchain and Why a Command Line Client Helps
A blockchain is a shared ledger that many computers keep in agreement. To use one, you typically need a client that can send requests, read the current state and submit transactions. Sentinel CLI is that kind of client for Sentinel Blockchain.
A command line client is useful because it is easy to script. A single line of text can check a status, record the output to a file, and run again tomorrow. Graphical tools are often better for browsing, but a terminal is usually more reliable for routine, repeatable work.
If you are new to blockchains, treat the command line as a precise instrument. Each command does exactly what you type, so reading the help text and understanding each argument before running it is a good habit.
Who Is Sentinel CLI For?
Sentinel CLI fits developers who build applications that talk to Sentinel Blockchain and want a terminal tool for testing ideas quickly. It also suits system administrators and power users who already work in PowerShell and prefer scripts over point-and-click interfaces.
A typical scenario looks like this: you write a short PowerShell script that queries the network every hour and saves the output to a log file. Once the command works in your terminal, you can add it to a scheduled task. Because the tool is open source, you can also inspect how each request is built before you rely on it.
People who want a visual dashboard, or who are just starting with blockchains, may prefer a graphical app. Sentinel CLI rewards users who are comfortable reading documentation and typing carefully.
How Command Line Tools Fit Into Web3 Development
Web3 development tools generally fall into a few groups: editors and IDEs for writing code, testing frameworks, hosted RPC providers, and command line clients. Each group solves a different problem, and most projects combine several of them.
An RPC endpoint is the address your software uses to send requests to a blockchain node. Hosted providers offer such endpoints so developers do not have to run their own node. A command line client like Sentinel CLI sits closer to the network itself, which is why it is often used for checks, quick queries and automation.
Understanding these roles helps you choose the right tool. A client for one network will not replace a general testing framework, and a testing framework will not replace direct access to the chain you are working with.

How to install Sentinel CLI on Windows
PS> winget install Sentinel.SentinelCLI- 1
Open PowerShell or Windows Terminal
Press the Start button, type PowerShell, and open it. Windows Terminal works equally well if you already use it. A standard user account is enough for the winget installation shown below.
- 2
Run the winget command
Type winget install Sentinel.SentinelCLI and press Enter. Winget downloads the package and installs it for you. Wait for the confirmation message before closing the window.
- 3
Install from the official source if you prefer
If you do not want to use winget, download the release from the official website at sentinel.co or from the Releases page of the GitHub repository. Download only from the official website or the official GitHub repository. Verify the SHA-256 checksum of the file against the value published with the release, then run the installer.

Open a new terminal and confirm the install
Close the current terminal and open a new one so the updated PATH takes effect. Then run the program with its help option to confirm it responds and to see which commands are available in version 0.3.2.
How to use Sentinel CLI
Sentinel CLI works best when you use it in a deliberate, step-by-step way. The steps below cover a cautious first session.
- Install the program with winget and open a new PowerShell window.
- Run the built-in help output and read the list of commands before you try anything else.
- Start with read-only commands that only display information, so you learn the output format without changing anything.
- Save important output to a text file, with the date in the file name, so you can compare results later.
- Keep private keys and seed phrases out of scripts and shared files. Use the tool's own options for signing, if you need them, and check each command before pressing Enter.
- Revisit the GitHub Releases page from time to time to see whether a newer version is available and what changed.
Pros & cons
- Free to use and released under the open source Apache-2.0 license
- Installs on Windows with one winget command
- Written in Go, which makes it straightforward to review and build from source
- Public source code lets you check how the tool behaves
- Well suited to scripting and repeatable command line tasks
- Focused on Sentinel Blockchain rather than a general Web3 toolkit
- Version 0.3.2 suggests an early stage, so commands and options may change
- Less suited to beginners who expect a graphical interface
- Fewer ready-made tutorials than for widely used tools such as Foundry
Is Sentinel CLI safe?
Sentinel CLI talks to a blockchain, so treat it with the same care you would give any tool that may touch keys or transactions. Install it only from the official website at sentinel.co or from the official GitHub repository, and verify the SHA-256 checksum or signature before running an installer. When you use winget, keep it updated and confirm you are installing the Sentinel.SentinelCLI package.
Never enter a seed phrase on a third-party website, in a chat or in a command you do not fully understand. Store keys in an encrypted wallet or on a hardware device, and test new commands with small amounts or on a test setup first. Check the latest version on the official website before you update, since early releases can change behavior between versions.
- Official source only. Download from sentinel.co. 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
Sentinel CLI differs from the similar tools listed on this site mainly in its focus. Remix Desktop is an IDE for writing Solidity contracts, and Visual Studio Code with Solidity extensions is a general editor with contract support. Foundry bundles forge, cast and anvil for contract development and local testing, while Tenderly CLI concentrates on debugging and monitoring contracts.
Postman is useful for sending JSON-RPC requests to nodes, and Alchemy, Infura and QuickNode provide hosted RPC endpoints. Sentinel CLI is built around Sentinel Blockchain itself, so it is the more natural choice when that network is your target. For broader contract work, pair it with a general toolkit.

Frequently asked questions
Yes. Sentinel CLI is free and released under the Apache-2.0 open source license, which allows you to use, study and modify the code. The program itself costs nothing, but blockchain transactions may carry their own network fees, which are separate from the software.
It can be, provided you get the file from the right place. Install through winget or download from the official website or GitHub repository, then verify the SHA-256 checksum. Avoid copies from unknown sites, and never enter a seed phrase into any program or website you have not checked carefully.
Open PowerShell and run winget install Sentinel.SentinelCLI. Winget downloads and installs the package automatically. After it finishes, open a new terminal window so the command is available, then run the help option to confirm the installation works correctly.
The latest version is 0.3.2. Because this is an early release, commands and behavior may change between versions. Check the GitHub Releases page or the official website before updating, and read the release notes to see what has changed since your last install.
No. Sentinel CLI is a command line tool, so you work with it by typing commands in a terminal rather than through a visual interface. Readers who want buttons and dashboards should look at graphical tools instead, while those comfortable with text commands will find the terminal approach direct.
Sentinel CLI is written in Go. Developers who want to inspect the code, or compile it themselves, can find the source on GitHub. Building from source requires Go, but the ready-made Windows program installed through winget does not need Go on your computer.
Verdict
Sentinel CLI is a sensible choice for developers and technically confident Windows users who work with Sentinel Blockchain and want terminal-based access. It is free, open source under Apache-2.0, and easy to install with winget. It is less suitable for beginners or for anyone who needs a broad, multi-network toolkit. Because the version is 0.3.2, treat it as an early tool, keep it updated, and test commands carefully before relying on them in automation.
