Service on the Blockchain — When Traditional Service Isn't an Option

Cryptocurrency fraud presents a problem that traditional litigation was never designed to solve. The assets are digital, the transactions cross borders in seconds and the people behind them often exist only as a string of characters on a blockchain. No name, no physical address, no obvious jurisdiction. So how do you serve a court writ on someone who, for all practical purposes, exists only as a wallet address?

Our partner, Yezdi Karbhari, recently handled a matter facing that exact question. A client had been defrauded of cryptocurrency, and the wallet holder responsible was overseas and anonymous. Personal delivery, registered post, and email service were all essentially rendered unavailable. Without valid service, the proceedings could not advance, and the wrongdoer would have escaped any legal consequence at all.

Service by tokenisation

Rather than allow the matter to stall, we successfully applied to the court for an order for substituted service by way of tokenisation. In practical terms, this involves delivering a digital token containing the sealed legal documents directly to the defendant's cryptocurrency wallet, the one verifiable point of contact available. The court granted the order accordingly and the case was allowed to proceed. This approach builds on the precedent set by the Hong Kong High Court in Worldwide A-Plus Limited HCZ 88/2024; HCA 2417/2024, which has opened the door to creative but legally sound methods of service in the digital asset context.

A legal system catching up with the technology

These developments reflect a judiciary actively adapting to the realities of modern fraud. Where a defendant operates exclusively in the digital space, the courts have shown they are willing to meet them there, whether through tokenised service of process or freezing injunctions over on-chain assets. These are not experimental workarounds. They are legitimate procedural mechanisms that ensure due process is upheld and victims are not left without a remedy simply because the wrongdoer chose to hide behind a wallet address.

What this means for victims of crypto fraud

The key takeaway is that anonymity and distance are not the shields they once were. The legal tools to pursue fraudsters across blockchains and borders now exist in Hong Kong but deploying them effectively requires solicitors who understand both the underlying technology and the procedural law that governs its use in litigation. Speed also matters; the sooner steps are taken to trace assets and apply for injunctive relief, the better the prospects of recovery.
