Fourth Amendment Shield: Court Blocks IRS Bulk Seizure of 24 Crypto Wallets

COURT CRUSHES IRS CRYPTO ACCOUNT SEIZURES — FOR NOW

A federal judge just blocked the government from grabbing 24 crypto wallets in a single stroke, ruling that blanket warrants violate the Fourth Amendment. The decision doesn’t end the IRS’s pursuit of hidden crypto wealth, but it forces agents to prove each account is tied to a specific crime before they can seize it. Markets exhaled; traders who thought every wallet was fair game now have breathing room.

The case began when IRS investigators used a John Doe summons to Coinbase, then asked a magistrate for warrants to seize 24 accounts allegedly controlled by U.S. taxpayers who failed to report foreign income. Rather than show probable cause for each wallet, prosecutors relied on statistical likelihood that some of the addresses held unreported assets. Judge Dabney L. Friedrich rejected that shortcut, holding that the Fourth Amendment still demands individualized suspicion even when the target is digital cash.

The ruling hands an immediate win to privacy-focused holders and to exchanges wary of fishing-expedition subpoenas. It also hands a setback to the IRS Criminal Investigation unit, which had hoped to scale the Coinbase precedent into routine bulk seizures. Nothing in the opinion shields criminals; it simply insists the government meet the same constitutional bar that applies to houses and bank accounts.

In plain English, agents can still chase tax cheats, but they must build a case wallet-by-wallet instead of vacuuming up addresses in bulk. That raises the cost and slows the tempo of enforcement—an implicit check on the agency’s reach into self-custodied assets.

For crypto markets the decision tilts the balance slightly toward decentralization: self-custody wallets now enjoy clearer constitutional shelter, reducing the chilling effect of mass data grabs. Stablecoin issuers and DeFi protocols that custody user keys face less immediate seizure risk, while traders gain negotiating leverage if exchanges are later asked to freeze funds on thin evidence. SEC authority is untouched—the case was tax, not securities—but the logic may bleed into future token-classification fights where the government tries to treat entire blockchains as evidence lockers.

The government can appeal, tighten its affidavits, or shift to grand-jury subpoenas; each path is slower and noisier than the shortcut the court just closed.
