Crypto-fraud, injunctions against persons unknown and the cost of Exchange non-cooperation Facts Freezing injunction Disclosure Costs Conclusions

In the recent English High Court decision in Wilden v Person Unknown, DHCJ Guy Vassall-Adams KC continued a proprietary and worldwide freezing order against an unknown cryptocurrency fraudster, reaffirming that crypto assets are property to which rights can attach and that exchanges which refuse to cooperate with fraud victims risk adverse costs orders.
The Court also granted a Bankers' Trust disclosure order against the cryptocurrency exchange, HTX, on which the assets were held. While Harneys does not advise on the law of England and Wales, this judgment may be considered in other common law jurisdictions such as the BVI, Cayman Islands, Bermuda and Cyprus, where freezing injunctions and disclosure orders in crypto-fraud cases are increasingly common.
Mr Wilden, a German businessman, was the victim of a targeted cryptocurrency fraud. A person unknown, using the alias "Brian Smith", contacted Mr Wilden about Bitcoin he considered lost following the closure of the EuropeFX platform. Smith claimed to be a UK-based investment adviser working for a company called LedgerLock, which he said was working with EuropeFX to recover lost Bitcoin and transfer it to new wallets.
The person unknown demonstrated detailed knowledge of Mr Wilden's EuropeFX transactions, including specific dates of purchase, account balances, trades, credits and withdrawals. Mr Wilden's forensic investigators subsequently concluded that this information may have been obtained from publicly available blockchain data or purchased databases. Believing the person unknown to be legitimate, Mr Wilden was persuaded to make a series of Bitcoin payments said to be necessary to satisfy technical and regulatory requirements. Between December 2025 and January 2026, Mr Wilden paid approximately EUR 2.5 million, converted into 32.46 BTC. Person unknown transferred a small amount back before locking Mr Wilden out of the LedgerLock platform and ceasing all contact.
Forensic investigators traced the funds to the HTX exchange (owned by Huobi Global SA, a company incorporated in Panama). The judge noted that HTX was on the FCA Warning List for operating in the UK without proper authorisation and is the subject of FCA enforcement proceedings for communicating financial promotions contrary to s21 of the Financial Services and Markets Act 2000.
The judge held that HTX responded to Mr Wilden's lawyers in a dismissive and formulaic manner, recommending Mr Wilden contact the police. The judge characterised HTX as "unwilling properly to engage with a legitimate request for the return of stolen cryptocurrency and is thereby providing a safe haven for the proceeds of crime".
The applicant for a freezing injunction must persuade the Court that:
the claimant has a good arguable case on the merits against the defendant;
there is a real risk that a judgment or award will go unsatisfied by reason of the unjustified disposal by the defendant of his assets; and
it is just and appropriate for the Court to grant the injunction.
The Court did not separately assess the requirements for a proprietary injunction although as is well known such injunctions are governed on a justice and convenience test usually applying the American Cyanamid guidelines and do not require risk of dissipation to be proved.
England and Wales, like the BVI, treats crypto assets as property to which rights can attach. The judge was satisfied on the basis of Mr Wilden's expert report that the identity of the crypto assets had been preserved. Importantly, following the principle established in D'Aloia v Persons Unknown, it was held that not only the remedy of tracing but also the remedy of following is available where the identity of the crypto asset is preserved despite mixing – a significant point for practitioners.
It was held to be self-evident that there was a risk of dissipation, as Mr Wilden's expert evidence showed that person unknown had already attempted to dissipate the funds through "pooling transactions" in whic...
