Upgrading Smart Contracts with the Diamond Standard in Solidity

As decentralized applications grow, the ability to upgrade smart contracts without changing their deployment address or losing state is crucial. This text-based course guides you through the core concepts of the Diamond Standard (ERC-2535) for modular and upgradeable Ethereum development. You will transition from writing rigid, single-use smart contracts to designing highly flexible, multi-contract systems. You will read through clear explanations of proxy patterns, understand how delegate calls work, and learn how to add, replace, and remove functions dynamically within a single address. What you'll learn: Understand the fundamentals of smart contract upgradability and proxy patterns; Master the ERC-2535 Diamond Standard architecture, including diamonds, facets, and loupes; Configure function routing and state variables to prevent storage collisions; Apply function replacement and removal techniques using Solidity code snippets; Analyze security best practices and access control for upgradeable contracts; Practice writing modular, gas-efficient smart contract code through written exercises. This course starts with key terminology and foundational proxy concepts before diving into the mechanics of the Diamond Standard. You will study step-by-step code walkthroughs that demonstrate how to safely modify contract behavior post-deployment. This course is designed for beginner Ethereum developers with a basic familiarity with Solidity who want to learn upgradeability patterns. No prior experience with proxy standards is required.
