NFT Snapshot

A script to scrape owners of a given NFT. Helpful for snapshots for airdrops, white lists, etc.

How To Use

1. Install dependencies (ethers and csv-writer) with npm install.
2. Open nft-snapshot.js and fill out the options at the top of the script:

• TOKEN_ADDRESS: Address of the token on the chain in question, formatted as "0x..."
• STARTING_TOKEN_ID: The script will start checking owners at this ID (defaults to 0).
• HIGHEST_TOKEN_ID: The script will check owners of IDs up to this number (inclusive).
• PROVIDER_ENDPOINT: A URL from Infura or Alchemy to create a JSON RPC provider.
• CHAIN_ID: The ID for the chain the NFT lives on (defaults to Ethereum Mainnet, ID: 1).
• FORMAT: The format that you'd like the final data organized by (see section below).

3. Run from the terminal with npm run start. It should check approximately 200 owners per minute.

Formats

There are two options for output formats for the data:

• tokensByOwner: Lists each owner, the count of the number of NFTs they own, and the specific IDs they own.
• ownerByTokenId: Lists all token IDs in order and the owner associated with each.
