Cryptocurrency privacy tools serve "essential protective functions" that restore a degree of financial privacy long taken for granted in traditional finance, according to a new report from non-custodial crypto platform ChangeNOW and digital asset management platform CoinRabbit.

The report, titled "Financial Privacy in the Digital Age," arrives amid an intensifying policy debate over crypto privacy. The U.S. Treasury's OFAC sanctioned mixer Tornado Cash in August 2022, and Dutch courts convicted its developer, Alexey Pertsev, in May 2024, signaling that privacy-preserving infrastructure itself can become a regulatory target. Against that backdrop, the report argues that privacy and regulatory compliance are not a zero-sum trade-off. Drawing on data from TRM Labs, Chainalysis, RAND Corporation, and the authors' own internal research, it contends that enforcement leverage is concentrated at fiat off-ramps rather than within upstream transactional privacy infrastructure.

Sanctions, Corporate Exposure, and Personal Safety

The report identifies three primary areas where privacy tools offer protection: financial access under economic sanctions and authoritarian regimes, corporate confidentiality as firms migrate to blockchain infrastructure, and individual security against scams and so-called "wrench attacks."

Sanctions, the report argues, disproportionately affect ordinary citizens who have little influence over the conduct being punished. When Iran was cut off from SWIFT, everyday citizens lost the ability to receive foreign payments, purchase imported goods, or collect family remittances, while the country's political class retained access to alternative channels. U.S. Treasury Secretary Scott Bessent has stated that Operation Economic Fury seized approximately $1 billion in Iranian cryptocurrency, including a single freeze of $344 million in USDT on the Tron network. That freeze, executed at the stablecoin issuer level rather than through transaction-level surveillance, illustrates the report's central claim about where enforcement capacity actually resides.

Corporate treasuries face a distinct set of vulnerabilities. Anyone possessing a company's wallet address can reconstruct its vendor relationships, payment frequencies, estimated payroll, and supply chain dependencies—information that would remain strictly confidential within traditional banking, where bank secrecy laws and correspondent banking relationships create layers of statutory and practical privacy. Statista research cited in the paper found that 36% of board members are concerned about internal data becoming public, with the average data breach costing $4.44 million.

For high-net-worth crypto holders, public blockchain transparency introduces direct physical risk. Walter Barrett, Chief Strategy & Growth Officer at CoinRabbit, said: "Public blockchain transparency lets anyone audit your net worth in real time, turning private wealth into public information."

According to CertiK, 52 verified wrench attacks occurred in the first half of 2026, exposing $124.1 million—nearly 12 times the figure from the same period in 2025. France alone accounted for 33 of these incidents, following data breaches at France Travail and ANTS that enabled attackers to match home addresses to suspected crypto holdings. French prosecutors have since charged 88 individuals, more than 10 of them minors.

Blockchain transparency also enables scammers to identify high-value targets. Internal CoinRabbit research found that roughly half of surveyed high-net-worth holders had experienced a targeted social engineering attempt within three years, and that 30% use data-broker removal services to sever the link between their identity and their on-chain activity.

Illicit Flows and the Enforcement Debate

The report acknowledges that crypto privacy is a double-edged sword. TRM Labs estimates total illicit crypto inflows at $158 billion for 2025, a 145% increase, with Chinese-language escrow and laundering networks accounting for more than $100 billion. Pig-butchering scams caused $75 billion in losses between 2020 and 2024, and 84% of verified fraud and scam inflows now move over stablecoin rails.

The dominance of stablecoin rails in illicit flows has drawn legislative attention. The U.S. GENIUS Act, signed into law in July 2025, established federal oversight of stablecoin issuers including reserve, redemption, and disclosure requirements, while the EU's Markets in Crypto-Assets regulation (MiCA), fully effective since December 2024, imposes its own issuer-level controls. Both frameworks operate at the points where crypto intersects with fiat—precisely the off-ramp layer the report identifies as the effective enforcement chokepoint.

Nevertheless, the authors argue that the decisive enforcement vulnerability "lies at the fiat off-ramps" where cryptocurrency becomes spendable currency, "not within the upstream transactional privacy infrastructure."

Albert Quehenberger, founder of AQ Forensics, echoed this view. Privacy "may increase the complexity of an investigation" but "rarely determines whether a criminal can ultimately be identified," he said, noting that attribution typically results from on-chain analysis, KYC records, exchange cooperation, and stablecoin issuer intervention rather than "relying on blockchain transparency alone."

The report's authors highlighted their own platforms as examples of privacy-preserving architecture, citing ChangeNOW's private transfer routing and CoinRabbit's custodial model.

"The privacy debate starts from the wrong assumption that ordinary users must prove they have nothing to hide by exposing everything," said Pauline Shangett, Chief Strategy Officer at ChangeNOW. She called on the crypto industry to "build systems where access is justified, targeted, and lawful, not universal by default."
