Anchor is a development framework for building Solana programs, the smart contracts that run on the Solana blockchain. It is aimed at developers who write on-chain logic in Rust and want a structured way to define accounts, validate inputs and generate client code, without writing much of the boilerplate by hand.
Anchor is free and open source under the Apache-2.0 license. On Windows it can be installed through the Scoop package manager, and the project is still actively maintained, with its most recent code update dated October 30, 2026. The sections below explain what the framework does, how to install it on Windows, how to use it, and how it compares with other tools in the Web3 development category.
What Is Anchor and Why Developers Use It
Writing a Solana program without a framework means handling account data layouts, deserialization and security checks yourself. Anchor packages those routine tasks into a standard structure. Most Solana programs written today follow its conventions, which makes code easier to read, review and hand over to another developer.
The framework is not a blockchain and does not hold funds. It is a set of tools that run on your development machine to help you produce a compiled Solana program and the code that talks to it.
Who Anchor Is For
Anchor suits developers who already know some Rust and want to build on Solana. Front-end developers working on a decentralized application can also use it, mainly through the generated IDL and TypeScript client, without writing on-chain code themselves.
Beginners to blockchain development usually find the Anchor documentation a practical starting point, because it introduces accounts, instructions and program-derived addresses in the context of working code.
Typical Use Cases
Common projects built with Anchor include token programs, escrow and marketplace logic, staking contracts and on-chain voting. Each of these needs a clear definition of who may modify which account and under what conditions. Anchor's account constraints let you express those rules declaratively, so the checks are visible at the top of each instruction.
Teams also use the framework to prototype quickly. A local test validator started from the CLI lets you deploy, call and inspect a program in minutes, before anything reaches a public network.
Key Concepts: Programs, Accounts and Instructions
On Solana, a program is stateless code, and data lives in separate accounts. An instruction is a call to a program that specifies which accounts it reads and writes. Anchor's main job is to describe these relationships clearly and check them before the program runs.
Understanding this model is essential. A program that forgets to verify that an account is owned by the expected program, or that a signer is present, can be exploited. Anchor's constraint system exists largely to make those checks hard to forget.
Key features
Rust eDSL for Solana programs
IDL specification
TypeScript client generation
CLI and workspace management
Supported coins
Anchor's documentation mentions Solana (SOL) as the native network for programs built with the framework, and Ethereum (ETH) in the context of cross-chain comparisons. Anchor itself is a development tool for Solana programs, so the assets you handle depend entirely on what your own program does.
How to install Anchor on Windows
PS> scoop install anchor-cli- 1
Install Scoop if you do not have it
Scoop is a command-line package manager for Windows. Open PowerShell and follow the installation instructions on the official Scoop website. Scoop installs tools into your user directory without requiring administrator rights.

Install the Anchor CLI with Scoop
In PowerShell, run the command scoop install anchor-cli. Scoop downloads the package and adds the anchor command to your path. Once it finishes, run anchor --version to confirm the installation.
- 3
Verify your download source
If you prefer a manual install, download the Anchor source or release files only from the official website at https://www.anchor-lang.com/ or from the GitHub repository at https://github.com/coral-xyz/anchor. Check published checksums or signatures where the project provides them before running any binary.
-
Use the Anchor Version Manager for version control
The project recommends the Anchor Version Manager (AVM) for installing and switching between Anchor CLI versions. AVM lets you pin a version per project, which helps keep builds reproducible when different Solana projects depend on different releases.
System requirements
- Windows with PowerShell available for running the install command
- Scoop package manager for the Scoop-based installation route
How to use Anchor
Anchor work is organized around a project workspace. After installing the CLI, you create a new project, write your program in Rust, build it and test it against a local validator. Once the tests pass, you can deploy to a network and generate client code for your front end.
A typical workflow looks like this:
- Run anchor init my_project to create a workspace with a starter program and test folder.
- Open the program source in the programs directory and define your accounts and instructions using Anchor's macros.
- Run anchor build to compile the program and produce the IDL file.
- Run anchor test to start a local validator, deploy the program and execute the test suite.
- Run anchor deploy when you are ready to publish to a configured cluster, such as devnet, before considering any other network.
- Use the generated TypeScript client in your application to call the deployed instructions.
Pros & cons
- Free and open source under the Apache-2.0 license
- Reduces boilerplate for Solana account handling and validation
- Generates an IDL and TypeScript client from one source of truth
- Workspace and CLI tools cover building, testing and deployment
- Installable on Windows through Scoop
- Recently updated codebase
- Requires working knowledge of Rust to write programs
- Solana-specific: the framework does not target other blockchains
- Learning the account model takes time for newcomers
- Recommended installation path goes through AVM, which adds a step
Is Anchor safe?
Anchor is open-source framework software rather than a wallet or a program that handles your keys by default, but it produces code that controls real assets once deployed. Download the CLI only from the official website or the GitHub repository, and verify the SHA-256 checksum or signature when the project publishes one. Never enter a seed phrase into a third-party website or a program you did not write or audit yourself. Test thoroughly on devnet or a local validator before mainnet deployment, because a bug in account validation can expose funds. Keep your Windows security tools enabled and rely on official sources rather than disabling protection to get a build working.
- Official source only. Download from www.anchor-lang.com. 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
Foundry, from the same broader category, is a toolkit for Ethereum smart contracts, built around the forge, cast and anvil tools. Solidity is the language used for Ethereum contracts, and its compiler solc is what developers use to produce bytecode. Anchor is different: it targets Solana, uses Rust, and centers on account structures rather than the Ethereum storage model.
Other entries in the catalog cover adjacent areas. Gear is a Substrate-based platform for spinning up dApps, and Ethermint brings the Ethereum Virtual Machine into the Cosmos ecosystem. Choose Anchor if your target is Solana. Choose Foundry or Solidity for Ethereum-compatible work, and look at the other listed tools if your project spans several chains.

Frequently asked questions
Yes. Anchor is free and open source under the Apache-2.0 license. You can download, use and modify the framework without paying a licensing fee. Costs on Solana itself, such as transaction fees and account rent, are separate from the framework.
The simplest route is Scoop. Install Scoop in PowerShell, then run scoop install anchor-cli. After that, confirm the installation with anchor --version. The project also recommends the Anchor Version Manager for managing multiple CLI versions.
Yes, for writing on-chain programs you need working knowledge of Rust. Front-end developers who only consume an existing program can work with the generated IDL and TypeScript client without writing Rust, although understanding the program's accounts and instructions still helps.
No. Anchor is built for Solana programs. Ethereum smart contracts are written in Solidity or Vyper and are usually built with tools such as Foundry. The Anchor documentation mentions Ethereum only in comparison contexts.
An IDL, or interface description language file, describes a program's instructions, accounts and types in a structured format. Anchor generates it automatically during the build step. Client libraries read the IDL to know how to call the program, so the front end does not need to parse your Rust source.
You can, but it is not advisable for a first project. Use a local validator to test, then deploy to devnet to check behavior on a public test network. Only after an audit and thorough testing should you consider mainnet, because deployed programs handling real assets cannot be fixed by simply editing the code.
The framework is open source and published on GitHub, which allows public review. Install it from the official website or the Scoop package, verify checksums where available, and keep your antivirus enabled. The safety risk lies more in the programs you write and deploy than in the CLI itself.
Verdict
Anchor is a practical choice for Windows developers building on Solana who want structured, readable programs and generated client code. It is free, open source and actively maintained. It suits teams comfortable with Rust and beginners willing to learn the Solana account model. If your work targets Ethereum or several chains at once, compare it with Foundry or the other tools in this catalog before you commit.
