Holders
Token & NFT holders snapshot
Rebuild ERC-20 balances or ERC-721 ownership from Transfer events on any supported L1, L2, or testnet — then download CSV, JSON, or TXT for airdrops and classroom labs.
Mainnet selected — use a short block window on busy contracts.
Scans in ≤1000-block chunks (public RPC limit) and auto-splits if a chunk is still too large. For NFTs, widen the range to cover mints; transfers before fromBlock are not visible.
Results appear here with download actions. Tip: deploy a practice ERC-20 or NFT on or Sepolia, transfer to classmates, then snapshot.
