Which lists is your wallet on?
Paste a wallet. We check every open drop against OpenSea allowlists and on-chain gates, fold away the copycats, and only tell you what we can prove.
My wallets
Save up to 10 wallets with a label. Check all runs them one after another and merges what closes soon. Each wallet gets a stray as its seat marker; it is decoration, not something you own.
Anyone with the link sees these addresses and labels. Nothing is stored on our side. Opening it never saves them for the other person without a click.CCFF00 holders
Drops with a stage for CCFF00 holders: an on-chain gate, a stage named for CCFF00, or a labelled guess from the gate study.

List drops with a stage open now. Public mints and likely junk are folded below.

A list stage can be checked once it opens. Turn on alerts and we ask for you when it does.
How did it do
Floor against mint price, with on-chain sales. Currencies are never added together. A floor is the cheapest listing, not a trade.
Public mints · Open to all, no list needed. Nothing to check.
Likely junk · Copycats and duplicate launches. The raccoons can have these.

How this works, and what it cannot tell youMethod, limits, and what we store.
How a whitelist works here
There are three kinds of mint whitelist on this chain, and only one is common. Across all the SeaDrop history we can read: 13,249 OpenSea signed stages, 20 merkle allowlists, and 11 on-chain token-gate events on 2 drops (none since August). So watching the chain for an address being added to a list finds almost nothing: for a signed stage the rule lives on OpenSea's server and no block records it.
We ask OpenSea to prepare a mint for your address. If it hands back list calldata (signed, merkle or token-gated), you are on that drop's list. If it refuses and names the stage, you are not. A public mint permit is not a list: anyone gets one, so it is shown as open to all, never as a yes. An "insufficient balance" reply says nothing about the list (OpenSea checks funds first), so it is shown as could not check. "Reached its limit" means the wallet already minted its share: it is shown as already minted, with the count read on chain.
Where the gate guess comes from
The rule is hidden but the result is not: every mint is on chain with the minter and the stage. We take the wallets that cleared a gated stage and check what they hold in common. It is labelled a guess on every card.
How drops are sorted, and what "likely junk" means
- established: at least 7 days old with 150+ holders and real trading.
- has buyers: at least 5 market sales adding up to 0.05 ETH/WETH or 100 USDG. thin trading is a few sales for small change. no trades yet is normal for a drop still minting.
- likely copy: the name matches an established or famous collection after ignoring case, spacing and look-alike letters, from a different contract and creator. duplicate launch: the same name launched twice within a day.
Prices keep their own currency: USDG is never turned into ETH, and volumes are never added up. A floor-vs-mint multiple only appears when both are in the same currency, and the floor is the cheapest listing, not a sale.
What it does not do
- It does not mint, connect, or ask you to sign. "Use my wallet" only reads your address.
- A check is not stored as yours. We keep OpenSea's answer for a wallet until its list window changes, so the next person to check the same wallet does not spend another request. Saved wallets live in this browser only.
- Alerts do store something: the wallets you pick, your settings, your browser's push address and what we already told you. They expire 30 days after you last open this page, and turning alerts off deletes them.
- A push needs your device on. The push service holds it for a few hours; an alert about a list that has closed is dropped, not sent late.
- It does not vet or endorse drops. Anyone can deploy one. Mint only on opensea.io.
Limits worth knowing
- Open stages only. OpenSea answers for the stage that is open now, so a list that has not opened reads "when it opens".
- Bounded. One check asks about up to 30 open list drops, closing soonest first, and the whole site has a small hourly and daily OpenSea budget. When it is used up, a drop reads "could not check", never no.
- The gate list is inference. It needs at least five winners, and a collection can rank because its holders mint a lot.
- Trust signals are signals. No X account is worth noticing, but absence is not guilt. A creator's own site is theirs, not ours: we show its address, not a badge.
