Europol, the European Union's law enforcement agency, has its eyes on the popular bitcoin privacy tool Wasabi Wallet, documents verified by CoinDesk show.

Marked for “law enforcement only,” a two-part report by Europol's European Cybercrime Centre (EC3) analyzed the privacy tool’s impact on using the Bitcoin blockchain to investigate crimes.
"Things are not looking good" for law enforcement thanks to this relatively new software, the EC3 warned, citing data from leading blockchain analysis company Chainalysis estimating how much money is filtering through Wasabi for criminal purposes.
"According to [Chainalysis], over the last three weeks, BTC in the amount of nearly 50 million USD were deposited into Wasabi with almost 30% coming from dark web markets,” says the first part of the report, circulated to law enforcement members in April. “This is a significant amount, relatively speaking, given the dark web transactions are estimated to have only 1% share of total transactions."
Europol’s observations highlight a long-simmering tension between governments around the globe and Bitcoin privacy advocates. The blockchain is transparent, making it a useful tool for the former to thumb through accounts and transactions to track down criminals.
Privacy advocates, on the other hand, want to make bitcoin transactions harder to trace, partly so that more people will want to use the payment system, but also as a matter of principle.
EC3 is in the business of "combating crime in a digital age" – often online financial crimes. Its report mostly just outlines what Wasabi is: A wallet that tries to get around Bitcoin's radical transparency, giving users more privacy by scrambling transactions together and confusing the trail. The second part of the intelligence briefing, published in May, dives into how a law enforcement officer can try to detect Wasabi transactions on the blockchain, and how to use the wallet to make a transaction.
The report was leaked on Telegram recently, and Europol’s press department confirmed its authenticity.
It was written "only for a law enforcement audience," Europol's press department told CoinDesk, adding that "the report does not contain any operational information."
Reports like this one "are regularly sent out from the Cybercrime Centre at Europol to the EU Law Enforcement Community and our partners in those countries with which we have working arrangements in place," a spokesperson added. "Europol has a number of different kinds of strategic reports and operational, analytical reports. The report at hand falls in the category strategical report."
Still, it offers a peek into the law enforcement agency’s thinking.
"How popular is the service?" the guide reads, answering: "Clearly popular enough to spark our interest."
It asks whether law enforcement can "demix" these transactions, answering that "realistically speaking, in most cases the answer is negative," though if a user messes up, there are ways to do it.
zkSnacks, the company behind the Wasabi wallet, did not respond to a request for comment by press time. A six-figure equity investment last year by publicly traded Canadian firm Cypherpunk Holdings valued zkSnacks at $7.5 million.

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

What to know:
- Ukraine has no legal framework for Web3 prediction markets, and current legislation provides no recognition for such platforms.
- Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.
- Legal changes are unlikely in the near future, as Parliamentary revisions to gambling definitions are extremely improbable during wartime, leaving prediction markets in a legal deadlock.
