Session

Consumable Interface

Ethereum
ERC-2135FinalAccepted and stable

Users hold NFT tickets/passes that can be 'used' or 'consumed' — once consumed, the token is burned or marked used (like tearing a concert ticket). Design implications: show clear 'consumable' badge on eligible NFTs, design prominent 'Use/Redeem' button, display consumption history and remaining uses, show who can consume (owner vs delegated consumer). Design decisions: whether consumption is reversible (affects undo UI), how to visualize partially consumed multi-use tokens, confirmation flow strength for irreversible consumption, showing consumed tokens in wallet (grayed out vs hidden).

Stages: Specialized Interactions

Session

Consumable NFT Extension

Ethereum
ERC-4400FinalAccepted and stable

Users can assign a 'consumer' to their NFT who can use it without owning it — like lending your metaverse land to a builder while keeping ownership. Design implications: show separate 'owner' and 'consumer' roles on NFT detail pages, design 'Assign Consumer' action distinct from transfer, display consumer address/ENS with clear role label, show 'You are consumer' vs 'You are owner' states. Design decisions: whether to show consumer history, how to handle consumer permissions expiration (if implemented), UX for revoking consumer access, visualizing the owner-consumer relationship in collection views.
