Check It is a free scanner. Paste an address, a token contract, a coin name or an ENS name, and it tells you what the chain actually says about it — before you send anyone money.
It is open to everyone. No wallet connection, no sign-in, and nothing you paste is stored or tracked.
What you can paste in
| You have | What you get back |
|---|---|
| A wallet or contract address | Age, activity, holder count, and the signals that commonly indicate a scam token — no liquidity, a tiny holder set, freshly deployed |
| A coin by name | Which contract genuinely corresponds to that coin, so you can tell the real one from the dozens of copies using the same name and logo |
An ENS name (something.eth) |
Who owns it, its history, when registration expires — and whether it is simply available to register |
Chains covered
Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, Solana, and Flow.
Why we built it
Almost every crypto loss we hear about starts the same way: someone was sent an address and had no way to check it. The information needed to spot the problem is public and sitting on the chain — it is just not in a form a normal person can read. Check It reads it for you.
It is a reading tool, not advice. A clean result is not a guarantee, and you should still be careful with anything you did not go looking for yourself.
