Deal With Claim Sign Scam

The Claim Sign scam is part of a growing wave of crypto wallet drainer campaigns that impersonate real blockchain services. In this case, scammers mimic the Sign Protocol platform, deceiving users with a fraudulent token reward offer. Victims are prompted to connect their digital wallet to the site—an action that quietly grants access to their funds via malicious smart contracts.

If you’ve seen a pop-up promising token airdrops from “Sign Protocol” or were redirected to a site resembling sign.global, you may be a target of this dangerous crypto scam.

In-Depth Threat Analysis

How the Attack Works

Victims typically come across a misleading link via Twitter, Discord, or Telegram—posing as an airdrop for early supporters of Sign Protocol. Once on the spoofed site, users are asked to connect their Web3 wallet (such as MetaMask). The action appears harmless but authorizes a smart contract embedded with commands to transfer your funds out.

What Happens After You Connect

As soon as you approve the smart contract request, the attacker gains the ability to move funds from your wallet. There are no warnings or confirmations—everything is automated and legally “signed” by your consent to the contract. Unlike traditional malware, this scam leaves no files behind, which makes detection more challenging.

Should You Be Concerned?

Yes. The “Claim Sign” scam is a silent financial weapon. If you engage with the site and sign any transactions, there’s a high risk of your cryptocurrency portfolio being emptied. This scam doesn’t require you to download anything—it exploits wallet permissions granted by the user.

Scam Interaction Example

This scam does not rely on email or traditional phishing text. The deception occurs through a fake website interface resembling a legitimate blockchain project. Here’s an example of the lure used:

“Claim your $SIGN tokens for supporting Sign Protocol! Connect your wallet to receive your airdrop. Limited-time event!”

This message is typically seen on the fraudulent site or embedded in a social media post linking to it.
