A sleepdrop is a fraudulent cryptocurrency scheme where scammers send unsolicited tokens to users' wallets, falsely suggesting these tokens originate from a legitimate source. This airdrop does not directly endanger user funds, but serves as bait by impersonating tokens from popular DeFi protocols. Recipients are then directed to a phishing website through the seemingly innocuous free tokens. Once on the site, users are vulnerable to ice-phishing attacks, where they are misled into signing transactions that appear legitimate. These transactions, however, are designed to transfer the user's assets to the scammer's wallet, resulting in financial losses.

Similar to an airdrop, sleepdrops aim to take advantage of the network effect by engaging existing holders of a particular blockchain-based currency, such as Bitcoin or Ethereum in their currency or project

An initial investigation by Forta Network and Blockfence revealed that sleepdropping, particularly targeting Ethereum users, has caused over $11.5 million in losses since its discovery in December 2022. These operations utilize sophisticated methods, including social media and fake websites, to lure victims. The prevalence of sleepdrops has sparked discussions on wallet security measures and highlights the need for increased vigilance among cryptocurrency users.
