Crypto’s Insider Problem: 56% of ERC-20 Token Listings Since 2021 Show Signs of Insider Trading

A Solidus Labs study, examining tokens listed on major crypto platforms, also shows how serial insider traders have systematically taken advantage of token listings and announcements

NEW YORK–(BUSINESS WIRE)–#blockchain–In a new study, Solidus Labs, a category-definer for crypto and DeFi-native market surveillance and risk monitoring, has found that insider trading in crypto is far more prevalent than previously reported. Data from Solidus HALO’s DEX-based insider trading detection tool shows evidence that insiders have traded against more than half of all ERC-20 token listing announcements on major centralized exchanges since 2021.1

In total, Solidus has identified more than 100 entities – individual cryptocurrency wallets, or groups of connected wallets – that have executed over 400 suspected insider trades since January 2021.

51 “serial insiders” have used decentralized exchanges to buy and then sell soon-to-be-listed cryptocurrencies on two or more occasions, with certain serial insiders trading against more than 25 distinct listings apiece. Of the 234 ERC-20 token listings announced by the centralized exchanges examined in the report since January 2021, 131 have shown signs of insider activity, in some cases netting individuals over $200,000 in profits within minutes.

The report – which is the first part of Solidus’ Crypto Market Manipulation Report Series – provides extensive data on the challenge of crypto insider trading, with case studies and walkthroughs of the methods used by crypto insiders.

“Our study affirms that DEX-based insider trading is a major market integrity problem — but one with a clear solution,” says Chen Arad, CXO and co-founder of Solidus Labs. “The permanent, public, and traceable nature of blockchains means that we can detect and deter this phenomenon with unprecedented transparency. With this technology, we can help regulators and exchanges enable safe crypto trading.”
