What is Sui’s Kiosk?

Kiosk is a native smart contract module on the Sui blockchain, designed to standardize and simplify the way NFTs are stored, managed, and traded. It acts as a programmable NFT storefront—ideal for devs who want to avoid reinventing the wheel for every NFT-related project.

Whether you’re building a marketplace, a game asset exchange, or a digital collectibles gallery, Kiosk offers you secure, customizable building blocks.

🤔 Why Build with Kiosk?

Imagine you’re launching an NFT app. You’ll likely need a way for users to store assets safely. A way to list and buy assets.

Kiosk handles all that for you. Instead of writing all these flows from scratch (and risking bugs 🐛 or exploits), you use Kiosk’s battle-tested API.

🧪 Example App: Building with Kiosk

Let’s get into a real example. You’ll create a basic NFT module, then use the Kiosk module to deposit it, list it, and allow others to purchase it.

Step-by-Step Code Breakdown

module 0xNFT::simple_nft {
    use sui::object::{UID};
    use sui::tx_context::TxContext;

    struct SimpleNFT has key {
        id: UID,
        name: String,
        description: String,
        url: String,
    }

    public entry fun mint(
        name: String,
        description: String,
        url: String,
        ctx: &mut TxContext
    ): SimpleNFT {
        SimpleNFT {
            id: UID::new(ctx),
            name,
            description,
            url,
        }
    }
}
