U.S. prosecutors are using a new tactic: asking digital asset issuers to freeze or blacklist wallets voluntarily, bypassing traditional seizure warrants. This practice, reinforced by the GENIUS Act, allows authorities to freeze first and ask questions later, shifting the burden of proof to asset holders.

Holders often find their funds frozen due to alleged connections to upstream illicit activity, even if they are innocent bystanders. The blockchain's pseudonymity and traceability make it difficult for investigators to distinguish between criminal participants and unwitting recipients. Once frozen, recourse is limited; issuers defer to the government, and holders must prove their innocence to regain access.

Experts recommend engaging experienced legal counsel, documenting transaction histories, and considering proactive communication with authorities. For issuers, establishing clear policies on handling freeze requests and maintaining transparent records can mitigate litigation risks.
