 In this tutorial, we'll walk you through building an old-timey [internet guestbook](https://en.wikipedia.org/wiki/Guestbook)! (Trust me, they were all the rage back in the day.) We'll be examining how the project is constructed, starting with the smart contract. Then, we'll turn that deployed smart contract into a "bindings package," allowing us to seamlessly integrate it into our frontend project. To get our users authenticated, we'll be using Stellar's new passkeys capability and giving each of our users their very own smart wallet. As a bonus, this guestbook is _already_ a usable project (on Testnet) you can experiment with and use **right now**! After this tutorial, you'll have a solid understanding of how smart contracts and web applications can work together in harmony. You'll also have practical tools and examples for how you might integrate passkey-powered smart wallets into your own projects.

 To build this guestbook application, we'll need a few pieces.
 
 - **Application framework:** we're using SvelteKit, opting for a type-checked project using TypeScript. SvelteKit (and Svelte on its own) is quite a capable framework, and we'll be using some of its features in this project. However, we will not be diving into those Svelte-specific areas very heavily in this tutorial. The source code of the project is freely open and available and has some decent informational comments throughout if you would like to peruse it for those purposes.

 - **A way to interact with the network:** this is a TypeScript application, and we're using the `@stellar/stellar-sdk` for this. You could make traditional `fetch` requests if you wanted to, depending on your deployment decisions. In either case, we'll need the SDK to interact with keypairs and transactions. We'll also be using a data indexer to access historical network events, and we'll cover more of this at a later point in the tutorial.
-- **A way to interact with a user's account:** we're foregoing the traditional wallets here, and we'll use `passkey-kit` to give our users a smart wallet to interact with. They can interact with this smart wallet (via passkey-kit) through methods they're already familiar with (thumbprints, face ID, etc.).

 With the move to smart contract development, a newly emerging utility in the Stellar ecosystem is the "[Soroban template](../../guides/dapps/soroban-contract-init-template.mdx)." These templates can help alleviate the burden of writing boilerplate code, and can help adapt typical Stellar development workflows into framework-specific reference templates. We've created [just such a template](https://github.com/ElliotFriend/soroban-template-sveltekit-passkeys) that can help you get started developing with SvelteKit and passkeys from the very beginning. You can either use the template on the GitHub website:

 Or, you can (fork and) clone the template repository locally, and start working that way:
