Solidity Workshop - Migrate a Smart Contract from ERC20/721 to LSP7/8

Join Jean Cavallera, Smart Contract team lead at LUKSO, as he delves into how to refactor the Solidity contract code of an ERC20 and ERC721 token to transform it into the LSP7 and LSP8 token standards on LUKSO. Discover how these new standards enhance security, flexibility, and functionality for digital assets. 🌐 Visit our website: 👉 https://lukso.network/ 💬 Join our Discord: 👉   / discord   📚 Technical Documentation: 👉 https://docs.lukso.tech/ 0:00 - Introduction and Workshop Overview 0:13 - Workshop Title: Transitioning from ERC20/721 to LSP7/8 0:19 - Importance of Refactoring Solidity Contracts 0:30 - Features of LSP7 and LSP8 Standards 0:42 - Introduction of the Speaker, Jean 1:00 - Introduction to the Hands-On Workshop 1:08 - Setting Up the Workshop Environment 1:46 - Using OpenZeppelin Wizard for ERC20 Token 2:24 - Explanation of LSP7 Contract Package 2:43 - Importing LSP7 Contract Packages 3:03 - Refactoring ERC20 to LSP7 4:08 - Setting Up GitHub Repository and GitPod Environment 5:43 - Starting the Refactoring Process 6:03 - Creating a Sample Token with OpenZeppelin 7:04 - Overview of ERC20 to LSP7 Refactoring Steps 9:09 - Detailed Explanation of Refactoring Steps 10:14 - Force Parameter in LSP7 11:18 - Mint Function in LSP7 12:01 - Specifying Token Types and Divisibility 13:10 - Differences Between ERC20 and LSP7 13:54 - Code Example: Refactoring Mint Function 15:01 - Using Constants in LSP7 17:22 - Transfer Function in LSP7 19:03 - Data Parameter in LSP7 20:05 - Notification Mechanism in LSP7 22:09 - Practical Example of Receiving Tokens 24:07 - Using Universal Receiver Contract 26:09 - Spam Protection and Custom Rules 27:28 - Switching to Practical Code Examples 28:09 - Completing Mint Function Refactoring 30:11 - Name Parameter Feature in Solidity 31:01 - Code Clarity and Readability Tips 33:05 - Handling Non-Divisible Tokens 34:04 - Single Transfer Function in LSP7 35:03 - Gas Usage and Efficiency in LSP7 36:09 - Burn Function in LSP7 38:00 - Using Preset Contracts in LSP7 39:19 - Overview of ERC721 to LSP8 Refactoring 40:02 - Example Code for LSP8 Contract 42:04 - Token ID Formats in LSP8 43:04 - Practical Examples and Use Cases 45:00 - Differences in Transfer Functions 47:09 - Summary of Refactoring Process 48:17 - Conclusion and Next Steps
