Holders.at
Holders.at is an NFT platform created by Jack Quack that enables users to copy wallet addresses containing NFTs from a selected collection, export them, or share them via a link. With Holders.at, developers of NFTs can capture snapshots of every wallet holding NFTs in any collection on Polygon and Ethereum. Even novice NFT creators can collect wallet addresses that contain their own or other widely-recognized NFTs without requiring any coding. Developers can subsequently focus on these wallets to airdrop their NFTs or establish white lists.
