Definition. The share of Ethereum gas consumed by transactions interacting with non-fungible tokens. The category includes both NFT token-contract standards (ERC-721, ERC-1155) and the NFT marketplaces (OpenSea, Blur, LooksRare, Rarible, SuperRare) where those tokens trade.

Interpretation. A rising share means NFT activity outbid other categories for finite Ethereum blockspace, a falling share means it was outbid or the underlying activity contracted.
