Learn Move 101

Want to learn Move with real examples? Start building today!

Here you’ll find hands-on Move examples covering smart contracts, asset management, and on-chain logic. Learn by doing with clear, practical guides.

The modules on these pages are snippets that show one concept each. They are declared at the literal address 0xcafe, which only the holder of that address can publish to. To build or publish one, create a package with supra move tool init, put the module in its sources directory, and replace 0xcafe with your account address or with a named address that you define under [addresses] in Move.toml. The functions are public fun, not entry fun or #[view], so they are meant to be called from other Move code and cannot be called with supra move tool run or supra move tool view.

Getting Started with Move

Learn Move with step-by-step example—building a strong foundation for smart contract development on Move.

Unsigned Integers in Move

Learn how Move's unsigned integers affect storage, performance, and gas efficiency.

Math Operations in Move

Move supports basic math operations with integer precision, requiring typecasting for different unsigned integer types.

Using Vectors in Move

Vectors in Move are dynamic lists that adjust in size, ideal for managing data collections, including structs.

Reading Resource Data with borrow_global

borrow_global reads a resource struct from a specific address without a signer, but the function must declare acquires ResourceName.

Pass-by-Value vs. Pass-by-Reference

Move uses pass-by-value for copies and pass-by-reference (& for reading, &mut for modifying) to data handling.

Adding Elements with vector::push_back

vector::push_back adds elements to a vector using a mutable reference (&mut), allowing dynamic storage updates.

Emitting Events with event::emit

Events let smart contracts send signals that external apps can track in real time.
