Check an address before you send
Address poisoning tricks people into copying a lookalike address from their own history. Paste the recipient and we compare it with everyone you have really paid.
FAQ
Frequently asked questions
What is address poisoning?
Scammers create an address whose first and last characters match one you really use, then send you a $0 or fake-token transfer from it so it shows up in your history. Next time you copy an address from your history, you copy theirs. Losses from this scam run into the hundreds of millions of dollars.
How does Send Check catch it?
Paste the recipient and, optionally, your own address. We compare the recipient against everyone you have actually sent to and flag lookalikes, addresses that only ever sent you $0 or fake tokens, token contracts and burn addresses that would swallow your funds, and first-time recipients.
Do I need to connect my wallet?
No. Send Check only reads public blockchain history. It never asks you to connect, sign or share a recovery phrase.
What else should I do before a large transfer?
Compare the full address, not just the start and end. Save trusted addresses in your wallet address book. Send a small test amount first and confirm it arrived.
