# BUILD

- [Aleph Zero smart contracts basics](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics.md): We invite developers to explore the smart contract functionalities on the Aleph Zero Testnet. This guide will explain how to get started!
- [Setting up a Testnet account](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics/setting-up-a-testnet-account.md): All you need to know about navigating the Testnet can be found here as we go over the two crucial components necessary to take advantage of this test environment.
- [Installing required tools](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics/installing-required-tools.md): Before running your first smart contract on Aleph Zero, you will first need to prepare your computer for development in Rust and ink!. Here's a handy guide to get you started.
- [Creating your first contract](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics/creating-your-first-contract.md): As now your machine is ready for development, it's time we build our first smart contract. The example contract we are going to develop in this tutorial is a simplified version of the ERC20 token.
- [Deploying your contract to Aleph Zero Testnet](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics/deploying-your-contract-to-aleph-zero-testnet.md): In this tutorial, we will go over the some of the ways of interacting with the smart contract environments on the Aleph Zero blockchain.
- [Extending your contract](https://docs.alephzero.org/aleph-zero/build/aleph-zero-smart-contracts-basics/extending-your-contract.md): Here you will find a collection of "how to" on various topics related to writing smart contracts in ink!
- [Cross contract calls](https://docs.alephzero.org/aleph-zero/build/cross-contract-calls.md): This section covers the more advanced topic of calling another contract from your code.
- [Using references](https://docs.alephzero.org/aleph-zero/build/cross-contract-calls/using-references.md)
- [Using dynamic calls](https://docs.alephzero.org/aleph-zero/build/cross-contract-calls/using-dynamic-calls.md)

- [Aleph Zero Signer integration](https://docs.alephzero.org/aleph-zero/build/aleph-zero-signer-integration.md): Learn how to integrate Aleph Zero Signer into web apps.
- [Front-end app: smart contract interaction](https://docs.alephzero.org/aleph-zero/build/front-end-app-smart-contract-interaction.md): Learn how to query a contract's state and send signed transactions in your front-end application.
- [Security Course by Kudelski Security](https://docs.alephzero.org/aleph-zero/build/security-course-by-kudelski-security.md)
- [ink! Developers Security Guideline](https://docs.alephzero.org/aleph-zero/build/security-course-by-kudelski-security/ink-developers-security-guideline.md): This guide aims at supporting ink! developers who want to deploy their project on the Aleph Zero blockchain. It has been developed as part of the partnership between Aleph Zero and Kudelski Security.
- [Lesson 1 - Getting started with ink!](https://docs.alephzero.org/aleph-zero/build/security-course-by-kudelski-security/lesson-1-getting-started-with-ink.md): In this lesson, you will learn how to install the necessary tools and deploy a simple smart contract.
