Blockchain data firm Chainalysis revealed the results of Operation Spincaster, a global initiative to combat “approval phishing” scams in the cryptocurrency space.
These scams have resulted in losses of $2.7 billion in crypto assets since May 2021, highlighting the urgent need for coordinated action against such fraudulent activities.
Background of the Chainalysis Operation “Spincaster”
According to Chainalysis, Operation Spincaster was a global expansion of a collaborative effort that first launched with Canada’s Calgary police in March 2024.
The operation was conducted between April and June and involved a series of “operational sprints” across six countries, spanning 12 public sector agencies and 17 crypto exchanges.
This blockchain data firm disclosed that the concerted effort led to the identification of over seven thousand criminal-linked leads, marking a significant step forward in the fight against crypto fraud.

Approval phishing scams involve fraudsters tricking victims into signing an “approval” message that grants access to their crypto wallets.
These scams can take various forms, from convincing fake crypto apps to sophisticated romance scams where trust is built over time before the scammer requests wallet access.
Chainalysis implemented a “three-pronged” approach in Operation Spincaster, which includes increasing public awareness about approval phishing scams, providing crypto exchanges with proactive surveillance tools to trace suspicious wallets, and enhancing law enforcement capabilities to combat these crimes.
The operation’s success was evident in its outcomes, with Chainalysis able to trace fund flows, leading to the closure of criminal-linked accounts and the seizure of illicit funds.
During one of the sprints, participants contacted a potential victim directly, warning them of an imminent threat.
This timely intervention allowed the individual to revoke approvals and prevent the loss of over six figures worth of cryptocurrency.
Phil Larratt, Chainalysis’ director of investigations, emphasized the importance of their crypto investigations tool in this effort.
He said,
“Exchanges, in particular, use Chainalysis to conduct thorough background checks on transactions, monitor for signs of illicit activity, and prevent fraud.”
The Broader Context of Crypto Scams And Recent Industry Developments
The unveiling of Operation Spincaster comes at a time when various types of phishing scams are on the rise in the crypto space.
According to Chainalysis, since 2019, around $100 billion in funds from known criminal wallets have been laundered through conversion services where cryptocurrencies are exchanged for fiat currency.
Launderers employ various sophisticated techniques to obscure the trail of illicit funds. Crypto mixers, for instance, blend assets from multiple sources, making it difficult to trace their origins.
The rise of sanctioned exchanges, such as the Russian platform Garantex, has also facilitated these illicit activities by providing a means to convert unlawfully obtained crypto into cash.
Despite these challenges, the transparent nature of blockchain technology allows for more accurate tracing of financial flows compared to traditional banking systems.
These challenges have brought regulatory pressure on blockchain-powered financial systems and have seen crypto giants like Tether partnering with Chainalysis to monitor transactions and combat illicit activity.
Tether disclosed that it is launching monitoring and analysis tools with Chainalysis to identify crypto wallets that may pose risks or be associated with illicit and sanctioned addresses.
On May 14, Tether froze $5.2 million in USDT due to phishing links as part of its efforts to enforce strict network controls and combat money laundering.
