Snapshot Tool ### Introduction The **D3fenders Snapshot Tool** helps NFT founders and project teams clearly understand who holds their NFTs - and what those holders are doing with them -at the exact moment decisions need to be made. Whether you are preparing an **airdrop**, building a **reward system**, creating an **allowlist**, or protecting your community from abuse, accurate holder data is essential. The Snapshot Tool provides a fast, reliable way to generate that data across multiple blockchains without requiring custom scripts or deep technical knowledge. At a glance, teams can see: * Who currently holds NFTs * How many tokens each wallet owns * Which NFTs are actively listed on marketplaces * How ownership is distributed across the collection *** ### Why Accurate Snapshots Matter In Web3, many issues around airdrops and rewards don’t come from bad intent — they come from incomplete or misleading data. Without a reliable snapshot, teams risk: * Rewarding wallets that are actively flipping NFTs * Missing loyal holders due to indexing gaps * Over-distributing tokens or rewards * Creating confusion or distrust within the community The D3fenders Snapshot Tool removes this uncertainty by combining **on-chain ownership data** with **real-time marketplace listing awareness**, giving teams a clearer and more actionable view of their community. *** ### Built for Real-World Conditions Most snapshot tools assume ideal infrastructure: perfect indexers, single-chain collections, and marketplace-only visibility. D3fenders Snapshot was built for real environments: * Multi-chain collections * Collections identified by contracts or update authorities * Marketplaces with delayed or partial data * Founders who need clarity, not black-box automation Manual verification and explicit workflows are supported by design, not treated as failures. *** ### Designed for Founders and Community Teams While the Snapshot Tool is production-grade under the hood, its purpose is simple:\ **give non-technical teams the same clarity developers rely on.** You shouldn’t need to write scripts, manage APIs, or stitch together CSV files just to understand your holders. The Snapshot Tool is built to be: * Easy to use * Repeatable * Transparent * Export-friendly --- # Agent Instructions This documentation is published with GitBook.
