Design implications: show privilege list with individual expiry dates, add 'Share Privilege' action, display privilege holder vs token owner. Design decisions: how to visualize privilege spreading/cloning — referral tree view, privilege inheritance tracking, balance utility discovery with UI complexity.","hasDetailedContent":true,"content":{"id":"EIP-5496","summary":"EIP-5496 lets a single NFT carry multiple distinct privileges. Instead of one NFT = one permission, you can track \"VIP access,\" \"backstage pass,\" \"merch discount,\" and \"meet & greet\" all on the same token. Each privilege can be granted, revoked, or transferred independently. Perfect for event tickets, membership cards, and subscription bundles where users expect multiple perks from one token.","applicability":{"whenToUse":["Your product addresses: nFTs represent only
