# Smart Contracts

- [Writing Smart Contracts](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts.md)
- [RUST Contracts](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts.md)
- [Phron smart contracts basics](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-smart-contracts-basics.md): Join us on the Phron Testnet to explore smart contract functionalities—this guide will walk you through setting up, deploying, testing, and accessing tools to build secure and scalable dApps.
- [Setting up a Testnet account](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-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.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-smart-contracts-basics/installing-required-tools.md): Before running your first smart contract on Phron, 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.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-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 Phron Testnet](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-smart-contracts-basics/deploying-your-contract-to-phron-testnet.md): In this tutorial, we will go over the some of the ways of interacting with the smart contract environments on the Phron blockchain.
- [Extending your contract](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/phron-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.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/cross-contract-calls.md): This section covers the more advanced topic of calling another contract from your code.
- [Using references](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/cross-contract-calls/using-references.md): The Bulletin Board example uses a reference to the HighlightedPosts contract to delete highlights. In this section, we will take a look at three basic building blocks of cross-contract calls.
- [Using dynamic calls](https://docs.phron.ai/developers/copy/smart-contracts/writing-smart-contracts/rust-contracts/cross-contract-calls/using-dynamic-calls.md): If you find yourself needing more expressive power than the references have to offer, you can use the dynamically constructed calls.
