But Tornado Cash co-founder Roman Semenov later <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/twitter.com\/semenov_roman_\/status\/1514949386865893380\">clarified<\/a> that the instrument only blocks access to the decentralized application, or DApp, interface and not the underlying smart contract.\u00a0<\/p>\n<p>There have been traces of Tornado Cash in several controversial decentralized finance activities. In February&#8217;s $375 million Wormhole exploit, hackers experimented with Tornado Cash using stolen funds. The same month, the LooksRare team also partly used Tornado Cash to cash out over $30 million in crypto. A recent Rare Bears Discord phishing attack that nabbed $800 thousand in nonfungible tokens (NFTs) also involved hackers funneling the stolen funds through Tornado Cash.\u00a0Reports also emerged that funds from a $33 million Crypto.com exploit were being laundered via the DApp.\u00a0<\/p>\n<p>However, it appears that Semenov has had enough of the protocol&#8217;s association with alleged illicit activities, discussing the potential consequence of jail time for noncompliance with regulators in blocking access to blacklisted individuals.\u00a0<\/p>\n<blockquote class=\"twitter-tweet\">\n<p lang=\"en\" dir=\"ltr\">Now do the &#8220;Jailed&#8221; list for ones that are not bending backwards to be compliant<\/p>\n<p>\u2014 Roman Semenov in Dubai\ufe0f  (@semenov_roman_) <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/twitter.com\/semenov_roman_\/status\/1514954838651674625?ref_src=twsrc%5Etfw\">April 15, 2022<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><br \/>\n<template data-name=\"subscription_form\" data-type=\"defi_newsletter\"><\/template><\/p>\n<\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
