4. Introduction to IPFS

Learn about the Interplanetary File System (IPFS), a decentralized data storage system, and its use in NFT development. Understand the concept of hashing data, pinning it on IPFS nodes, and the global network of nodes, differentiating it from blockchain in terms of data storage and access. Duration: 8min

5. Upload and use IPFS data (token URI)

This section explores using IPFS for hosting NFT images and metadata, focusing on OpenSea for practical demonstration. It also covers the customization of NFT appearances by allowing users to choose their Token URI, thus determining the look of their tokens. Duration: 7min

6. Writing the deployment script

Learn how to write a deployment script for NFTs. This includes using Forge script for deploying Basic NFTs and understanding the contract deployment process, highlighting the importance of testing and compiling before deployment. Duration: 2min

7. Test the NFTs smart contract

Focuses on testing the basic NFT contract using Solidity. It includes detailed steps for conducting tests like confirming the NFT name and testing the mint function, emphasizing the importance of testing for successful smart contract deployment. Duration: 11min

8. Quiz: NFTs Collection Intro Quiz

Questions: 9

9. Interact with a smart contract

Teaches how to interact with Solidity smart contracts, particularly for minting NFTs. It includes setting up the necessary environment and scripts, and deploying NFTs using tools like Foundry and IPFS. Duration: 3min

10. Deploy your NFTs on the testnet

Guides on deploying NFTs to a testnet and importing them into MetaMask. It covers the use of Anvil for deployment, extracting contract data, and using MetaMask to interact with the deployed NFTs. Duration: 7min

11. IPFS and Pinata vs HTTP vs on chain SVGs

Discusses the pros and cons of using IPFS, HTTP, and on-chain SVGs for storing NFT data. It covers the pitfalls of each method and introduces services like Piñata Cloud for securing digital assets on IPFS. Duration: 4min

12. What is an SVG?

Explains Scalable Vector Graphics (SVGs), their advantages, and how to create them. The lesson includes coding snippets for SVG creation and highlights their use in NFTs for on-chain storage. Duration: 8min

13. Create a dynamic NFTs collection

Focuses on creating dynamic SVG NFTs, particularly a mood-changing NFT that alternates its appearance. It includes detailed instructions for setting up the NFT project, minting the NFTs, and defining their appearance. Duration: 5min

14. Encoding SVGs to be stored onchain

Teaches encoding SVGs in Base64 format for on-chain storage in NFTs. It covers the process of encoding and testing SVG NFTs, ensuring their proper functioning and appearance Duration: 17min

15. Modify the NFT image onchain

This section is about adding functionality to change the NFT's appearance on-chain. It includes creating a function to flip the mood of an NFT, ensuring only the owner can modify it Duration: 3min
