CoinRabbit & ChangeNOW Report Finds Businesses Face Privacy Challenges on Public Blockchains

According to a new study by digital asset management platform and crypto loan provider CoinRabbit and crypto super app ChangeNOW, financial privacy does not undermine regulatory compliance. Written by CoinRabbit & ChangeNOW and presented by Decrypt, the report reframes financial confidentiality as an indispensable shield for both corporate treasuries and individual safety, while law enforcement continues to track illicit funds at regulated gateways.

Key Highlights

  • Transparent wallet addresses function as public net-worth registries, exposing high-net-worth holders to targeted extortion and social engineering.
  • Open blockchains leak proprietary supply chains, vendor contracts, and cash flows to competitors, impacting the 36% of corporate board members who rank internal data exposure as their top operational threat.
  • Law enforcement tackles illicit flows at centralized fiat off-ramps, KYC touchpoints, and stablecoin issuer freezes rather than through continuous public surveillance.
  • The report highlights CoinRabbit's custodial model and ChangeNOW’s private crypto transfers as benchmarks for privacy-preserving infrastructure.

The Real-World Risks of Public Blockchains

While permanent ledger visibility makes protocol audits simple, it introduces severe operational hazards for businesses and individual investors alike.

Unlike standard bank accounts, public crypto addresses broadcast payment histories, vendor lists, and balances to anyone with an internet connection. Citing Statista figures, the report notes that 36% of corporate board members view internal data leaks as their top operational threat, with average breach costs hitting $4.44 million. On an open ledger, competitors can track corporate wallets to map supply chains, estimate payroll, and deduce profit margins in real time.

For individual investors, open ledgers create direct physical and digital threats:

  • Physical Extortion

CertiK tracked 52 verified "wrench" attacks in H1 2026 alone, accounting for $124.1 million in stolen assets. In France, which accounted for 33 of these cases, public data breaches allowed criminals to link residential addresses directly to crypto holders.

  • Targeted Cybercrime

Internal CoinRabbit survey data reveals that roughly 50% of high-net-worth clients faced targeted scam attempts linked to visible wallet activity, prompting 30% to use data-removal services to unlink their identity from on-chain addresses.

"Public blockchain transparency lets anyone audit your net worth in real time, turning private wealth into public information," noted Walter Barrett, Chief Strategy & Growth Officer at CoinRabbit.

Sanctions, Remittances, and Geopolitical Pressure

The study also analyzes how privacy mechanisms preserve financial access during economic instability and geopolitical crises.

When global banking networks disconnect jurisdictions, civilians suffer first. Citing Iran's exclusion from SWIFT, the authors show that while political figures maintained alternate payment channels, ordinary citizens lost the ability to receive family remittances or buy imported goods. While targeted enforcement remains active (as the U.S. Treasury's Operation Economic Fury seizing around $1 billion in illicit crypto, including a $344 million USDT freeze on Tron), base-layer privacy tools allow compliant populations to maintain financial lifelines.

Why Enforcement Target Fiat Off-Ramps

Addressing concerns around financial crime, the report cites TRM Labs data placing total illicit crypto inflows at $158 billion for 2025. Chinese-language laundering networks accounted for over $100 billion, pig-butchering scams caused $75 billion in losses between 2020 and 2024, and 84% of fraud proceeds moved through stablecoins.

However, investigative data demonstrates that raw ledger transparency is rarely what solves financial crimes. Actual enforcement leverage sits at centralized fiat conversion points.

"Successful blockchain investigations rely on the combination of on-chain analysis, behavioral patterns, KYC information, exchange cooperation, stablecoin issuer interventions, and traditional investigative methods," stated Albert Quehenberger, founder of AQ Forensics. “In practice, attribution is achieved by connecting multiple sources of evidence rather than relying on blockchain transparency alone. The objective should therefore not be to eliminate financial privacy, but to ensure that investigators retain lawful access to the critical points where digital assets interact with regulated service providers.”

Moving Beyond "Public by Default"

The study concludes by advocating a fundamental shift in Web3 design: replacing mandatory public exposure with permissioned, targeted transparency.

"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. "Industry architecture should provide access to financial information only when it is justified, targeted, and lawful."

Moving forward, the industry's focus must shift toward architectural design: replacing default public ledger transparency with selective disclosure mechanisms that uphold standard business confidentiality while preserving regulatory compliance.
