A newly searchable database of New York City property records has drawn criticism from figures within the cryptocurrency industry, who express concerns that it could inadvertently expose wealthy property owners to physical harm. The database, released by the New York City Department of Finance, aggregates publicly available property assessment data into a format that critics argue makes it easier to identify individuals with significant real estate holdings.
The core of the criticism, according to reports, is not that property records are public, but that their organization into a searchable database transforms scattered information into a centralized resource. This, critics argue, effectively singles out affluent individuals. Hayden Adams, associated with Uniswap, described the database as “the worst mass doxxing I’ve ever seen.” Mert Mumtaz of Helius stated that the database “crossed a line by transforming scattered public records into a centralized resource that effectively singled out wealthy individuals.” Nic Carter of Castle Island Ventures warned that “an easily searchable database of affluent property owners could make potential victims easier to identify.”
These concerns are amplified by a documented rise in violent incidents targeting cryptocurrency holders. Security firm CertiK reported 72 verified crypto “wrench attacks” worldwide in 2025, a 75% increase from the previous year, resulting in over $40.9 million in losses. By the first half of 2026, CertiK reported 52 such attacks, with financial exposure surging nearly twelvefold year over year to $124 million.
Recent incidents underscore the severity of these threats. In April, French authorities charged 88 suspects in a crackdown on violent crypto kidnappings. In May, U.S. prosecutors indicted three men accused of armed home invasions in California. In June, two Texas brothers pleaded guilty to kidnapping a Minnesota family and stealing over $8 million in cryptocurrency. These events highlight a pattern of escalating criminal activity linked to cryptocurrency wealth.
The New York City Department of Finance annually releases assessed property values, and the FY2027 assessment roll, supplemental market value data, and property tax guides are publicly available through the city’s Open Data portal. However, critics argue that the aggregation and searchability of this data create a new level of vulnerability. As one critic noted, “Yes real estate records are semi public but this is an easily searchable database and target list.”
Uncertainties remain regarding the exact date the searchable database was made public and whether the New York City Department of Finance has responded to the criticism. The specific year for some of the mentioned legal actions in France and the U.S. also requires clarification. Despite these uncertainties, the situation highlights a growing tension between public access to information and the need for individual security in an era of increasing digital connectivity and targeted crime.
