Check a crypto wallet address before you send to it or accept from it
Sending to the wrong address can't be undone, and accepting funds from a hacked or sanctioned wallet can get your own account frozen. A risk screen takes seconds and costs $0.005.

What a wallet screen looks for
A risk screen checks an address against public lists of known bad actors and gives a verdict: high-risk, suspicious or clean. Ours looks for:
- Sanctions: addresses on the US OFAC sanctions list.
- Theft and hacks: wallets linked to exploits and stolen funds.
- Phishing and scams: addresses reported for draining wallets, fake giveaways and fraud.
- Mixers and laundering: addresses that route funds through mixing services.
- Malicious contracts and fake tokens: contracts built to trap whoever interacts with them.
When to check
- Before sending a large payment, especially to an address you were given in a chat or email.
- Before accepting a payment or an over-the-counter trade from someone new.
- Before approving a contract that asks to spend your tokens.
- When a wallet suddenly sends you tokens you didn't ask for (a common phishing lure).
How to check a wallet in one call
The wallet risk check ($0.005) covers Base, Ethereum, Solana, BNB Chain, Arbitrum, Polygon, Optimism and Avalanche. For a fuller picture, the wallet profile ($0.01) shows balances and holdings, and the wallet report ($0.10) also screens the wallet's top counterparties and describes how it behaves.
- Copy the full address. Check every character, or paste it straight from the source. Address-poisoning scams use look-alike addresses that share the first and last characters.
- Add the checker to your AI app. Get a free key on the set-up page and paste the connector URL into Claude or Cursor.
- Ask. "Is this wallet safe to send to on Ethereum? 0x…" Your assistant runs the screen and explains the verdict.

Questions people ask
Is a clean result a guarantee?
No. A screen only knows about addresses that have been reported or linked to known incidents. A brand-new scam wallet can look clean. Treat "clean" as "nothing known against it", not as proof it is safe.
Is this a legal sanctions compliance check?
No. It is a quick screen of public data to catch obvious problems. Businesses with legal screening duties should use a regulated compliance provider.
Does it show who owns the wallet?
No. It reports what is publicly known about the address's activity. We don't identify or return data about private individuals.
How much does it cost?
$0.005 per check, charged only when the check succeeds. In Claude or Cursor the first 20 calls a day are free, with no sign-up.
