How to Start with Move-Based Programming in 2026

Why move-based programming 2026 matters

Move-based programming is shifting from a blockchain-specific niche to a broader architectural standard in 2026. Originally designed for Sui and Aptos, its resource-oriented model addresses fundamental safety issues that plague traditional software development. As AI accelerates code generation, the need for deterministic, error-resistant structures has become critical for maintaining system integrity.

In conventional programming, data can often be inadvertently duplicated or discarded, leading to subtle state corruption. Move enforces strict ownership rules: every piece of data has a single owner, and it cannot be copied or destroyed unless explicitly handled. This eliminates entire classes of bugs related to race conditions and memory leaks, making systems more predictable and secure.

This shift matters because 2026 software demands higher reliability. With AI handling routine coding tasks, human developers focus on system design and complex logic. Move-based programming provides a safety net that complements this workflow, ensuring that the core logic remains robust even as the volume of generated code increases. The composability of Move also allows developers to build complex systems from simple, verified components, accelerating development without sacrificing security.

Set up the Move development environment

To start writing move-based programming, you need the Move CLI. This tool lets you compile, test, and deploy smart contracts on Move-enabled blockchains like Sui and Aptos. The installation process is straightforward and works on macOS, Linux, and Windows.

1

Install the Move CLI

Open your terminal and run the official installation script. This downloads the binary and adds it to your system path automatically.

curl https://install.move-lang.org/install.sh | sh

If you prefer manual installation, you can download the latest release from the Move Language GitHub repository and place the binary in your PATH.

2

Verify the installation

Confirm that the CLI is installed correctly by checking the version. This step ensures the binary is accessible and not corrupted.

move --version

You should see output similar to move-cli 0.0.1. If the command is not found, restart your terminal or check your environment variables.

3

Create a new project

Initialize a new Move project. This creates the standard directory structure, including sources, tests, and Move.toml.

move new my_first_move_project
cd my_first_move_project

The Move.toml file defines your project’s dependencies and package settings. You can edit this file to add libraries or configure compiler flags.

4

Run a basic test

Compile and test your project to ensure everything is working. This step catches syntax errors and logic issues early.

move check
move test

If the tests pass, you are ready to start writing smart contracts. The Move compiler enforces strict type safety, which helps prevent common bugs in blockchain applications.

Once your environment is set up, you can begin writing your first Move module. The language’s resource-oriented design ensures that digital assets are handled securely and predictably.

Write your first resource-based module

In Move, a resource is a struct that cannot be copied or dropped. It represents unique assets like tokens or NFTs. This design prevents accidental duplication or loss, which is the core reason blockchains use Move for value transfer.

We will build a simple module that defines a MyCoin resource and a function to mint it. This mirrors how you create new assets on networks like Aptos or Sui, where every unit of value is a distinct resource object.

1

Define the resource struct

Start by defining the struct. In Move, you must mark it with resource to enforce uniqueness. You also need to define the fields that hold the asset's data, such as a value field for the coin amount.

struct MyCoin has key {
    value: u64
}

The has key capability tells the Move compiler that this struct can be stored in the global storage of an account. Without this, the struct is just a temporary value, not a persistent asset.

2

Create the minting function

Next, write a function that creates a new instance of the resource. This function takes an account address as an argument. Inside, you instantiate the struct with the desired value and store it in the account's global storage using move_to.

fun mint(account: &signer, amount: u64) {
    let coin = MyCoin { value: amount };
    move_to(account, coin);
}

The &signer argument proves the caller has permission to store assets in their own account. This is a standard pattern in Move smart contracts to ensure security and ownership.

3

Add a getter function

To read the resource, you need a function that retrieves it from storage. Move requires you to borrow resources rather than move them out, ensuring they remain in storage unless explicitly destroyed.

fun get_value(account: address): u64 {
    borrow_global<MyCoin>(account).value
}

This function uses borrow_global to safely access the resource. If the resource doesn't exist, the transaction will fail, which is a safe default for blockchain state management.

This simple module demonstrates the core syntax of move-based programming. You define the asset, mint it to an account, and read its state. This pattern scales to more complex assets like NFTs or fractionalized tokens, where the resource struct holds additional metadata or proofs of ownership.

Compile and test the smart contract

Before deploying anything to the mainnet, you need to prove that your Move code compiles without errors and that your resource logic holds up under scrutiny. This phase transforms abstract type safety into concrete bytecode and verifies that assets cannot be duplicated or lost.

Compile to bytecode

Move code is compiled into Move bytecode, a compact format that the Move Virtual Machine (VM) executes. This compilation step is strict; the Move compiler enforces linear types, meaning every resource must be used exactly once. If your code tries to drop a resource or copy it implicitly, the compiler will reject it.

Run the move compile command from your project root. This generates .mv bytecode files in the build/<package>/bytecode_modules directory. These files are the actual units deployed to the blockchain. You can inspect them to ensure the compiler has correctly interpreted your struct definitions and function signatures.

Run unit tests

Bytecode compilation is necessary but not sufficient. You must run unit tests to verify business logic. Move’s testing framework allows you to simulate the blockchain state, including account balances and resource ownership, in a local environment.

Write tests in the tests directory of your module. Use move test to execute them. Focus on edge cases: what happens if a user tries to transfer a resource they don’t own? What happens if a transaction fails mid-execution? Your tests should catch these scenarios before they reach the network. A failed test here is a warning sign; a passing test is your first line of defense against exploits.

Common Move syntax mistakes to avoid

Move’s ownership model prevents data races, but it requires a mental shift from languages like JavaScript or Rust. Developers often try to reuse values after they’ve been consumed, leading to compilation errors that feel punitive rather than helpful. Understanding the difference between copying, moving, and dropping is the first step to writing valid Move code.

Forgetting that values are moved by default

In JavaScript, passing an object to a function usually passes a reference. In Move, passing a value to a function moves ownership to that function. If you try to use the original variable afterward, the compiler will reject it. This is not a bug; it is a feature that ensures data integrity.

fun transfer_token(token: Token) {
    // token is moved here and cannot be used again
}

fun main() {
    let token = Token { value: 10 };
    transfer_token(token);
    // error: value used here after move
    println!("Remaining value: {}", token.value);
}

Misunderstanding Copy and Drop traits

Not all types can be copied or dropped. Simple types like u64 can be copied freely, but complex structs like Token cannot unless explicitly marked with the @copy and @drop abilities. Forgetting to add these abilities to your struct definition will prevent you from using them in common patterns.

struct Token has copy, drop {
    value: u64
}

// Without 'has copy', this line fails:
let token2 = token1;

Ignoring resource capabilities

Move treats certain values as resources, which cannot be copied or dropped. These are typically used for assets like coins or NFTs. Trying to drop a resource implicitly will cause a compilation error. You must explicitly drop resources or transfer them to another account.

struct Coin has key {
    value: u64
}

// error: cannot drop resource
fn bad_example(c: Coin) {
    // compiler error: cannot drop resource
}

// correct: explicitly drop or transfer
fn good_example(c: Coin) {
    destroy c;
}

Using references incorrectly

References in Move are immutable by default. Trying to mutate data through a reference will fail. Use mutable references (&mut) only when you intend to change the value, and ensure the original owner allows mutation. This prevents accidental side effects in smart contracts.

fun update_value(val: &mut u64) {
    *val = 100;
}

fn main() {
    let mut x = 0;
    update_value(&mut x);
    // x is now 100
}

Seeing the code in action clarifies how Move handles resources and ownership differently from other smart contract languages. The official introduction by Sam Blackshear provides a clear visual reference for these concepts within a real development environment.

FAQ about move-based programming 2026

Is it worth learning Move in 2026?

Yes. While AI has lowered the cost of writing basic code, it has not eliminated the need for developers who understand complex system design. Learning Move is valuable because it focuses on safety and formal verification, skills that remain distinct from general-purpose scripting. As the industry shifts toward verifiable smart contracts, this niche expertise becomes more relevant, not less.

Is AI replacing Move developers?

AI is not replacing programmers; it is replacing narrow coding tasks. In 2026, AI can help generate boilerplate Move code, but it cannot yet define system architecture or debug complex edge cases in formal verification. Teams still need human developers to review tradeoffs, ensure security, and make product decisions. AI acts as a co-pilot, not a replacement.

Can I learn Move without prior blockchain experience?

Move is designed to be accessible, but prior knowledge of Rust or general systems programming helps. The language introduces unique concepts like resources and modules that differ from traditional object-oriented programming. If you are new to coding, start with Rust basics first. This foundation will make understanding Move's strict ownership model much easier.

How does Move compare to Solidity in 2026?

Move prioritizes security through a resource-oriented type system, while Solidity focuses on flexibility and widespread adoption. Move’s approach prevents common vulnerabilities like reentrancy attacks by design. For new projects where security is the primary concern, Move offers a safer starting point. Solidity remains the standard for existing ecosystems with massive liquidity.

What is the job outlook for Move developers?

Demand for Move developers is growing alongside the adoption of blockchains like Aptos and Sui. These networks require high-performance, secure smart contracts, creating a niche market for specialists. While the total number of jobs is smaller than for web2 roles, the competition is also lower. Developers with formal verification skills often command higher rates.
