You need an NFT contract address (or more) to test this. Contract Drawer should open automatically, but you can open it on the contracts button at the lower left.
About
Snapshooter allows non-technical web3 users, such as creators and marketers, to extract and visualize information from multiple NFT contract holders and export address lists for practical uses like airdrops and discounts. As more brands, communities, and merchants adopt NFTs as collectibles, tickets, products, invoices, discount tokens, etc., it becomes necessary to build the right tools to visualize and explore relationships between multiple contracts. For instance, how can we find out that 6,000 of the Wu-Tang NFT album holders also collected the Adidas OnChain Summer NFT? How can Base Frens determine how many of their holders participated in this hackathon (Supabald NFT)? Snapshooter is designed to discover these relationships and export the addresses of those holders-in-common for uses like discounts, airdrops, whitelists, or even messaging.
