Key Concepts

Move Language Basics

Abilities - Type capabilities:

• copy - Can be copied
• drop - Can be dropped (destroyed)
• store - Can be stored in objects
• key - Can be used as a key in global storage (objects)

public struct MyStruct has key, store {
    id: UID,
    value: u64
}

Object Model:

• Every object has a unique UID
• Objects can be owned (address), shared, or immutable
• Transfer functions: transfer::transfer, transfer::share_object, transfer::freeze_object

Common Patterns

Create and Transfer Object:

public fun create(ctx: &mut TxContext) {
    let obj = MyObject {
        id: object::new(ctx),
        value: 0
    };
    transfer::transfer(obj, tx_context::sender(ctx));
}

Shared Object:

public fun create_shared(ctx: &mut TxContext) {
    let obj = SharedObject {
        id: object::new(ctx),
        counter: 0
    };
    transfer::share_object(obj);
}

Entry Functions:

public entry fun do_something(obj: &mut MyObject, value: u64) {
    obj.value = value;
}

CLI Commands

# Create new project
sui move new my_project

# Build
sui move build

# Test
sui move test

# Publish
sui client publish --gas-budget 100000000

# Call function
sui client call --package <PACKAGE_ID> --module <MODULE> --function <FUNCTION> --args <ARGS>

# Get object
sui client object <OBJECT_ID>

Workflow

When answering Sui/Move questions:

1. Search references first:

   rg -i "topic" {baseDir}/references/move-book/book/ -l
   

2. Read relevant files:

   cat {baseDir}/references/move-book/book/<path>/<file>.md
   

3. Provide code examples from the references

4. Link to official docs when helpful:

   • Move Book: https://move-book.com
   • Sui Docs: https://docs.sui.io

Notes

• Move 2024 edition introduces new features (enums, method syntax, etc.)
• Sui uses a unique object-centric model different from other blockchains
• Gas is paid in SUI tokens
• Testnet/Devnet available for development
