When you start building on Sui, the first thing you’ll notice is how different it feels from EVM-based chains like Ethereum. Instead of a global state, Sui works with objects — and these objects can represent tokens, NFTs, accounts, or even entire applications. Your smart contracts are written in Move, a language designed for safety and asset management.

Steps:

1. Install Sui CLI and check version: curl -s https://get.sui.io | sh sui --version

2. Create a new Move package: sui move new hello_sui

3. Example contract: module hello_sui::hello { use sui::tx_context;

   public entry fun say_hello(name: vector<u8>, ctx: &mut tx_context::TxContext) {
       tx_context::log_utf8(ctx, name);
   }
   

   }

4. Build and deploy: sui move build sui client publish --gas-budget 10000

5. Call function: sui client call --function say_hello --module hello --package <PACKAGE_ID> --args "Hello Sui!"

Pro Tip: Start small, test your publishing pipeline, then build more complex apps.
