Use cases
One primitive. Four jobs.
Whitelists, airdrops, retroactives, governance — all from a single precise list, on demand.
Distribute tokens however you want
Proportional, capped to fight whales, square-root for softer curves, or a flat unit. Pro-rata splits a fixed budget cleanly.
Reward who held it then, not now
Snapshot any past moment — who held during the window that mattered, even if they sold since. Block-precise, ~30-second accuracy.
Voting power tied to engagement
Based on durable holdings, not last-second speculation. Square-root mode dampens whales while keeping the signal honest.
FAQ
Questions you'd ask if we sat down.
How accurate are historical snapshots?
We resolve the block nearest your chosen timestamp via DefiLlama (≈30-second accuracy) and replay every transfer up to that block. The output reflects ownership exactly as it stood. Block numbers are recorded in the receipt so you can verify externally.
Is my data stored anywhere?
No accounts, no database. CSVs and JSON archives live only on your machine. The Cloudflare edge caches API responses for a few minutes to reduce load — that's it. Shared snapshot links you publish via "Get a shareable link" stay in KV for one year.
What if my collection was deployed via Manifold or Foundation?
Factory-deployed collections are picked up by a secondary pass: we list contracts your wallet appears in, then check whether you're the OpenSea-indexed creator or contract deployer for each. Coverage isn't perfect — if anything's missing, paste the contract address directly.
What contracts get filtered out automatically?
A built-in blacklist removes known marketplace and protocol contracts that hold NFTs but aren't real holders — Seaport/Conduit, Blur Pool, X2Y2, LooksRare, NFTX, gem.xyz, burn addresses, and similar. These would otherwise eat your airdrop while the actual holders (who just listed their NFT on Blur, etc.) get nothing. Multi-sig wallets (Safe, Argent) are kept — they're real owners.
Does it cost anything?
No. The site is free and we don't sell data. Heavy abuse is rate-limited per IP; for sustained high-volume usage get in touch.
