Court Slaps IRS for Bulk Crypto Seizures, Demands Wallet-Specific Proof
COURT SLAPS IRS FOR CRYPTO ACCOUNT GRAB
Federal agents can’t keep twenty-four crypto wallets they seized without showing probable cause for each address. In a ruling that quietly rewires the government’s digital dragnet, a D.C. district judge handed the accounts back to their unknown owners and warned that bulk crypto seizures now face the same Fourth Amendment test as cash in a duffel bag.
The case began when IRS agents traced ransomware payments to a mixer, then cast a wide net that swept up two dozen accounts holding roughly $2 million in assorted tokens. Rather than proving each wallet had been used for crime, prosecutors relied on the single fact that the addresses interacted with the mixer. The court rejected that shortcut. Judge Dabney L. Friedrich ruled that “mere association” with a tainted service does not equal probable cause, and the government’s one-size-fits-all affidavit fell short of the particularity the Constitution demands.
The immediate winners are the pseudonymous account holders who now regain access to funds the government froze without individual evidence. The losers are investigators who counted on the sheer volume of on-chain data to justify mass seizures. Going forward, every crypto warrant will need wallet-specific facts, not just a chain-analysis report. That raises the bar for bulk subpoenas and may slow forfeiture actions that rely on mixer adjacency alone.
Translated into plain English, the opinion tells agents: prove the wallet before you grab it. The IRS can still chase ransomware proceeds, but it must now build a separate case for each address rather than sweeping up every hop on the blockchain. The ruling does not block future seizures; it simply forces prosecutors to do their homework one wallet at a time.
For markets, the decision tilts power back toward privacy tools and DeFi. Mixers and decentralized exchanges gain breathing room because traders know random adjacency to illicit funds is no longer automatic grounds for asset grabs. Centralized exchanges, by contrast, may face louder calls to collect more KYC data so the government can meet the new particularity test. Stablecoin issuers and large custodians should expect sharper subpoenas that name exact wallet hashes, not entire customer books.
The bigger message is simple: on-chain evidence is powerful, but it still has to clear the oldest constitutional hurdle—particularity—or the wallets walk free.
