  • PrimeNft.sol: Basic NFT with custom URI
  • VibeNft.sol: On-chain SVG NFT with switchable states
• test/:
  • unit/: Unit tests for contracts
  • interactions/: Tests for deployment and interaction scripts
• script/: Deployment and interaction scripts
• img/: SVG images used for the VibeNft

• Simple ERC721 implementation
