Building DeFi Smart Vaults on Arbitrum

In this course, we will explore how to use the Rust and the OpenZeppelin ERC4626 standard to create DeFi (Decentralized Finance) smart vaults. Through this course, we aim to enable students to: 1. Understand the logic of smart vaults and their applications in DeFi projects. 2. Acquire the skills to develop smart contracts using Rust.

Syllabus

Unit 1 - Course Objectives

This chapter will cover Arbitrum Stylus Smart Vaults Concept

Unit 2 - Configuration and Environment Setup

This unit discusses how to prepare a Rust project to make it suitable for running in a smart contract environment.

Unit 3 - Import Modules

This section introduces how to import several basic tools and modules to help us build our own smart contracts.

Unit 4 - Define VaultParams Struct

This section discusses setting up the basic parameters for smart contracts, especially the necessary steps when constructing Vaults token contracts that adhere to the ERC20 standard.

Unit 5 - Define Struct

This part introduces how to create a structured storage system for smart contracts and how to set up the contract's basic functionalities.

Unit 6 - Implement Vault Struct

This section covers how to implement the basic functionality of the Vault struct.

Unit 7 - Implement Deposit Function

This section introduces how to add a deposit function to a smart contract, allowing users to deposit assets and receive token shares in return.

Unit 8 - Implement Withdraw Function

This section introduces how to add a withdraw function, allowing users to withdraw assets from the contract.

Unit 9 - Retrieve Asset Address and Total Assets

This section introduces how to implement two basic query functions within a smart contract, allowing external users and contracts to access core information about the contract.
