As a researcher with a background in cryptocurrency and blockchain analysis, I’ve seen firsthand how cybercriminals have been adapting their tactics to evade detection in the rapidly evolving crypto ecosystem. The use of mixers, cross-chain bridges, and intermediary wallets is becoming more sophisticated, making it increasingly challenging for law enforcement and compliance teams to trace illicit funds.


As a researcher studying the evolving landscape of cryptocurrency transactions, I’ve noticed a concerning trend: cybercriminals are becoming more adept at using mixers, cross-chain bridges, and intermediary wallets to obscure the origin and trail of their ill-gotten funds. This sophisticated method of crypto money laundering makes it increasingly difficult to trace and seize illicit proceeds.

In recent times, the business world has been hit by various destructive schemes, showcasing the complex concealment techniques employed to launder illegally acquired money.

Layering in Crypto

In the context of money laundering, the process of concealing ill-gotten gains through complex transactions can take on different forms in traditional banking systems and cryptocurrencies. In conventional financial structures, this may include moving funds through numerous bank accounts and shell companies. Conversely, in the realm of cryptocurrencies, one frequently employed method for layering involves transferring funds through several intermediary personal wallets, often referred to as “hops.”

As a data analyst at Chainalysis, I can tell you that based on our most recent findings, reported to CryptoPotato, this strategy aims to conceal the link between the tainted funds during their initial placement and their subsequent incorporation into the criminal economy.

As an analyst studying on-chain transactions, I’ve observed a significant role played by intermediary wallets in the context of money laundering. These wallets typically handle around 80% of the value flowing through such channels. The increasing number of intermediary wallets suggests that criminals are intentionally adding more hops to their on-chain operations, making their activities more intricate and harder to trace.

Each leap increases the costs for unlawful users, implying that these additional stages are partly driven by the intention to bypass detection by law enforcement and regulatory bodies at crypto platforms. The number of intermediary wallets used between illegal wallets and conversion services is usually proportional to the extent of the illicit activity identified. For instance, the utilization of intermediary wallets reached its zenith in late 2022, a year marked by the highest cryptocurrency value received at addresses with questionable intent.

A growing portion of illicit funds passing through intermediary wallets are stablecoins.

State of Mixers

As a researcher studying the cryptocurrency market trends in 2024, I’ve noticed an uptick in the usage of mixers. In sync with the overall market activity surge, these privacy tools have gained considerable traction. Upon closer inspection of individual mixing services, I identified WasabiWallet, JoinMarket, and Tornado Cash as the ones demonstrating the most substantial growth.

As an analyst, I’ve noticed that Tornado Cash has experienced remarkable expansion over the last year, despite a significant drop in activity post-sanctions in 2022. In contrast, Samourai, which was anticipated to thrive in 2024, has seen a sharp decrease in growth following the Department of Justice’s actions against its key figures in April of the same year.
