Interpol dragnet exposes $122.5m cross-chain laundering wallet in 5,800-arrest sweep

An Interpol-coordinated operation spanning multiple jurisdictions has resulted in more than 5,800 arrests and uncovered a sophisticated crypto laundering network that relied on cross-chain swaps to obscure the movement of illicit funds, according to The Block. Investigators identified a single wallet that processed $122.5 million over a ten-month period as part of the scheme.

The scale of the crackdown underscores how deeply digital assets have become embedded in transnational fraud operations, and how law enforcement agencies are increasingly building forensic capacity to trace funds across multiple blockchains rather than treating each network in isolation.

Cross-chain swaps as a laundering typology

According to The Block’s reporting, the network at the centre of the operation used cross-chain swaps as its principal method of concealment, moving value between different blockchain networks to break the transactional trail that on-chain analytics tools typically rely on. This technique has become a growing concern among compliance specialists, who note that assets routed through multiple chains and bridges can be significantly harder to track than transactions confined to a single ledger.

The $122.5 million wallet identified during the investigation illustrates the scale that such networks can reach within a relatively short window of ten months, according to the report. For regulators, the case adds to a body of evidence suggesting that cross-chain infrastructure, while designed to improve interoperability for legitimate users, is also being exploited as a laundering conduit.

Scale of the enforcement operation

The more than 5,800 arrests reported mark one of the larger coordinated fraud enforcement actions involving crypto-linked activity in recent memory. Interpol’s involvement points to the cross-border nature of the network, with the agency typically acting as a coordinating body for national police forces pursuing suspects and assets across multiple countries.

For European and UK observers, the operation reinforces a pattern regulators have flagged repeatedly: that crypto-enabled fraud increasingly operates through international networks rather than isolated domestic schemes, requiring cooperation between financial intelligence units, exchanges and law enforcement bodies across jurisdictions.

Implications for forensic standards

The case is likely to feed into ongoing debates among regulators and industry bodies about tightening forensic standards for tracing crypto assets across chains. As cross-chain bridges and swap protocols proliferate, authorities have repeatedly called for stronger cooperation between blockchain analytics firms, exchanges and law enforcement to close the gaps that laundering networks exploit.

The Block’s report did not detail further specifics on the identities of those arrested, the jurisdictions involved beyond the coordinated nature of the operation, or the exact protocols used to execute the cross-chain swaps. PoundToken will update this story as further details emerge from Interpol or participating national authorities.
