In recent years, courts worldwide have been looking for new ways to handle the unique challenges of blockchain technology. A recent example comes from Brazil, where a court decided to use NFTs to serve legal notices on anonymous defendants in the BWA Brazil bankruptcy case.

Rather than sending paperwork by mail or email—usual methods that require knowing someone’s physical or digital address—this approach leverages the transparency of NFTs and blockchain. By targeting wallet addresses directly, the court aims to ensure individuals who might otherwise remain hidden are still informed of ongoing legal proceedings.

BWA Brazil Case Overview

The BWA Brazil situation involves allegations that the company operated as a pyramid scheme and acquired about 11,200 Bitcoins (BTC) using creditor funds prior to bankruptcy. At current prices, that amount of BTC is worth more than $900 million. To protect creditors’ interests, the court-appointed trustee petitioned for permission to interrupt the statute of limitations on potential claims tied to those crypto assets.

Because many of these assets were traced to wallet addresses without identifiable owners, traditional service methods were impractical. In response, the trustee asked the court to mint NFTs embedding the relevant legal documents and send them directly to the wallet addresses in question. This step was made possible by Bitcoin’s public ledger, which allows anyone to track transactions from one address to another.

Although pseudonymous, these addresses still offer a traceable path for blockchain-based notifications. The Brazilian Public Prosecutor’s Office supported the trustee’s request, indicating a growing willingness among legal authorities to recognize new technological methods in pursuing due process.

Other Notable Instances of NFT-Based Service of Process

Celsius Network Bankruptcy Case (October 2024)

During the Celsius Network LLC bankruptcy proceedings in the United States, the litigation administrator needed to recover assets that had been transferred to unidentifiable cryptocurrency wallets. The U.S. Bankruptcy Court for the Southern District of New York approved the use of NFTs to deliver summonses and complaints, considering it “reasonably calculated” to reach the unknown defendants.

U.S. District Court for the Southern District of Florida (March 2023)

In a separate case involving the alleged theft of nearly $1 million in cryptocurrency, Judge Beth Bloom allowed the plaintiff to serve process via NFTs. This decision was primarily driven by the anonymity of the defendants and the impracticality of using conventional methods, signaling the court’s openness to new digital tools for legal procedures.

Legal Considerations and Challenges

Due Process Compliance

Courts are tasked with ensuring that any method of service is sufficient to alert defendants to pending legal actions. NFT-based service can satisfy this requirement by being “reasonably calculated” to reach the intended party.

Defendant Anonymity

Even when an NFT summons reaches a specific wallet, there’s no guarantee that the individual responsible for that wallet will respond. Continued anonymity makes enforcing judgments and collecting potential damages more complex.

Jurisdictional Variations

Each country or region has its own rules for acceptable service of process. While some courts see NFT-based notification as a viable option, others have not yet clarified their stance.

Implications and Future Outlook

The use of NFTs in legal proceedings highlights how rapidly courts are adapting to the realities of digital assets and decentralized finance. By approving blockchain-based methods for serving process, judges and trustees acknowledge that many defendants in crypto-related cases may never be found using conventional methods.

As illustrated by the BWA Brazil case, Celsius Network bankruptcy proceedings, and other examples, these adaptations are gaining acceptance as a means to protect the rights of both creditors and plaintiffs. Moving forward, continued exploration of NFT-based notifications could shape how global legal systems handle cryptocurrency disputes.

While there are still questions about enforceability, privacy, and cross-border compliance, the trend suggests that blockchain technology could keep playing a significant role in the evolution of legal practices—and that courts will continue seeking new ways to reach participants in an increasingly decentralized financial landscape.
