Walkthrough

The pull request introduces a new section to the NFT tutorial, specifically for creating a universal ERC-721 NFT. This section includes an embedded YouTube video within a responsive <div> element, designed to maintain a 16:8 aspect ratio. The core tutorial content remains unchanged, focusing on NFT contracts on ZetaChain and EVM chains, including their minting and transferring functionalities. Existing explanations regarding cross-chain transactions and gas fee handling are preserved, ensuring the tutorial's technical integrity is maintained without altering any contract logic.

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Line range hint 1-24: Enhance tutorial with additional security considerations

While the tutorial is comprehensive, consider adding the following security-related information to make it more production-ready:

1. Gas Limit Configuration:

   • Explain why the gas limit is hardcoded to 700000
   • Recommend implementing an owner-controlled function to adjust gas limits
   • Discuss gas estimation strategies for different chains

2. Front-running Protection:

   • Add a section about potential front-running risks in cross-chain transfers
   • Suggest implementing mechanisms like commit-reveal schemes or minimum confirmation blocks

3. Event Monitoring:

   • Emphasize the importance of emitting events for critical operations
   • Provide examples of monitoring cross-chain transfers using events

Would you like me to provide code examples for these security enhancements?
