DynamicNFT & Static (Foundry)

This project demonstrates two ERC-721 implementations with full test coverage and deployment scripts using Foundry:

• StaticNFT: A minimal NFT with baseURI management and sequential token IDs.
• DynamicMoodNFT: An on-chain SVG NFT that can switch between HAPPY and SAD states, controlled by the token owner or an approved address.

---

Features

• ✅ StaticNFT

  • Sequential token IDs starting at 0
  • Metadata hosted off-chain (IPFS), referenced via baseURI
  • Configurable baseURI
  • Minting restricted from minting to zero address
  • Ownable with baseURI updates
  • Includes ERC721Burnable

• ✅ DynamicNFT

  • Fully on-chain metadata and SVG images (Base64 encoded in tokenURI)
  • Default mood = HAPPY
  • Token owners/approved accounts can flip the mood to SAD or back
  • Custom mint and burn functions
  • Tracks totalSupply
  • Token metadata includes attributes reflecting current mood
  • Includes ERC721Burnable

• ✅ Scripts

  • DeployStaticNFT.s.sol – Deploys StaticNFT
  • DeployDynamicMoodNFT.s.sol – Deploys DynamicMoodNFT
  • DynamicNFTFlip.s.sol – Script to flip the mood of a DynamicMoodNFT
  • InteractionSimple.s.sol – Example interaction: mints a StaticNFT
  • DynamicNFTMint.s.sol – Example interaction: mints a DynamicMoodNFT

• ✅ Tests

  • 100% coverage across all contracts
  • Covers constructor logic, minting, burning, reverting conditions, access control, URI generation, totalSupply, and flipping mood
  • Systematic test implementation for dynamic on-chain metadata URI checks using helpers

🔒 Security Notes

• Minting to zero address is prevented

• flipMood restricted to owner or approved addresses only

• Contracts use OpenZeppelin's battle-tested ERC721 and ERC721Burnable implementations

• Precise custom detailed errors and custom logics are implemented to ensure safety over the Openzeppelin Imports
