Public NFT Emote Repository

Ethereum
ERC-6381FinalAccepted and stable

Users can react to any NFT with emoji (like social media reactions) — reactions are stored on-chain in a public repository, enabling social signals around NFT value and desirability. Design implications: show emoji reaction counts on NFT cards, design emoji picker for reacting, display top reactions and total counts, show 'you reacted' state for user's own reactions, enable bulk reactions across multiple NFTs. Design decisions: which emojis to feature prominently, whether to show who reacted (privacy vs transparency), handling presigned reactions for gasless UX, reaction count display (exact vs abbreviated), emoji display consistency across platforms.

Public NFT Emote Repository V2

Ethereum
ERC-7409FinalAccepted and stable

Users can react to any NFT with full Unicode emoji support including skin tones and variations — supersedes ERC-6381 with string-based emoji encoding for future compatibility. Design implications: same as ERC-6381 but with full emoji picker including skin tone variants, handle variable-length emoji rendering, show diverse emoji options. Design decisions: whether to group emoji variants or show individually, handling emoji that render differently across devices, search/filter in expanded emoji set, backwards compatibility display for collections using both standards.
