Is Nansen safe? How to verify you are on the real site
The real Nansen
The official Nansen address is nansen.ai (Research, multi-chain). Any other domain claiming to be Nansen — with extra words, swapped letters, or an unusual ending — should be treated as a phishing risk.
Why Nansen gets cloned
Because Nansen asks you to connect a wallet and sign transactions, it is a target for phishing. Attackers copy the site pixel for pixel, then trick you into signing an approval that hands them your assets. The clone often ranks in ads or is shared as a link in Discord and Telegram.
How to stay safe on Nansen
Verify the domain is exactly nansen.ai. Never reach it through a random link or ad. Read every signature request before approving. Never enter your seed phrase. Use a tool that blocks known fakes and explains dangerous signatures before you sign.
