Cross-Chain Crypto Laundering Surges to $21.8B in 2025

Cross-chain crypto laundering is exploding. Criminals are rapidly shifting stolen digital assets across multiple blockchains, pushing illicit flows to a record-breaking $21.8 billion, according to a new report by blockchain analytics firm Elliptic.

That figure more than triples 2023’s total of $7 billion—and dwarfs the $4 billion seen in 2022. The sharp rise highlights how threat actors are using advanced techniques to cover their tracks in an increasingly fragmented crypto landscape.

How Criminals Are Hiding Crypto

Criminals aren’t just swapping tokens. They’re deliberately confusing the trail.

Elliptic found that:

• 33% of cases involved activity across more than 3 blockchains
• 27% used over 5 blockchains
• 20% spanned 10 or more

They use decentralized exchanges, cross-chain bridges, and anonymous swap services to move funds undetected. These swaps are often done through shady websites or Telegram channels and involve multiple rapid transactions to obscure origins.

North Korea and Industrial-Scale Scams

One of the most active players? North Korea. DPRK-linked hackers are behind 12% of the $21.8 billion estimate, using cross-chain methods to launder stolen funds from crypto hacks.

The Bybit exchange hack in February 2025—where $1.5 billion was stolen—is a textbook example. The attackers moved the stolen crypto across several blockchains using structured, multi-hop transactions to hide their tracks.

But it’s not just state actors. The rise in industrial-scale scams, memecoin rug pulls, and even gambling proceeds laundering shows that cross-chain tactics are spreading fast.

When a Crypto Swap Becomes Suspicious

Not all swaps are illegal—many are routine trading actions. But Elliptic warns that multi-hop and chain-hopping activity, especially when it incurs high fees and offers no financial benefit, is a clear red flag.

These tactics aim to confuse blockchain forensics and make recovery harder, if not impossible.

Conclusion

The rise of cross-chain crypto laundering signals a new phase in crypto crime. As criminals grow more sophisticated, simply watching one blockchain won’t cut it. Law enforcement and compliance teams must adapt—fast. The blockchain wild west just got a lot wilder.
