Summary of Changes

Hello @Rahul-Lashkari, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a valuable new example notebook that integrates the Gemini API with Solana smart contract development using the Anchor framework. The addition aims to provide developers with practical demonstrations of how AI can streamline various aspects of Web3 development, from code generation to understanding complex blockchain concepts, thereby enhancing the utility of the Gemini API for blockchain engineers.

Highlights

• New Solana Anchor Development Notebook: A new example notebook, 'Solana_Anchor_Development.ipynb', has been added to demonstrate how the Gemini API can assist with Solana smart contract development using the Anchor framework.
• Notebook Functionality: The notebook showcases several capabilities, including generating boilerplate Anchor (Rust) program code, visualizing and auditing Program Derived Address (PDA) seeds, generating TypeScript client tests, and explaining advanced Solana concepts such as Token-2022 extensions.
• Documentation Update: The examples/README.md file has been updated to include an entry for the new Solana Anchor Development notebook, making it discoverable alongside other examples.

Code Review

This pull request introduces a new notebook, Solana_Anchor_Development.ipynb, which is an excellent example of using Gemini to assist with complex development workflows like Solana smart contracts. The notebook is well-structured and covers code generation, security analysis, and test generation. The corresponding README.md has also been updated correctly. My review focuses on aligning the new notebook with the repository's style guide. The main points are using sentence case for titles and headings, employing a Colab form for model selection to enhance maintainability, and running the notebook formatting script to clear execution counts. These are mostly stylistic changes to ensure consistency across the cookbook. Overall, this is a valuable addition.
