On Thursday, January 15, 2026, Mari Terzaghi filed a complaint in the California Superior Court against Electric Solidus, Inc. d/b/a Swan Bitcoin, Fortress Trust, LLC, CRB Group, Inc., and DOES 1-25, alleging multiple damages related to the loss of her Bitcoin holdings.

Terzaghi, a resident of New York, claims that the defendants’ actions and omissions led to the loss of 21.172 Bitcoin, valued at approximately $2.4 million. The complaint lists ten causes of action, including fraud, negligence, negligent supervision, violation of the California Consumer Privacy Act (CCPA), violation of California data breach notification statutes, negligence under the Uniform Commercial Code (UCC), unfair competition, conversion, breach of fiduciary duty, and breach of implied contract.

The lawsuit alleges that Swan Bitcoin provided brokerage and account services to Terzaghi. Fortress Trust, a Nevada limited liability company with its principal place of business in Las Vegas, acted as the qualified custodian of her assets. CRB Group, Inc., a corporation with its principal place of business in Fort Lee, New Jersey, is the parent and controlling entity of Cross River Bank, which processed the unauthorized transfers.

Terzaghi claims that in May 2024, she maintained Bitcoin holdings through Swan Bitcoin and Fortress Trust. She alleges that she relied on the defendants to safeguard her cryptocurrency and IRA-related accounts in accordance with industry and regulatory standards.

The complaint states that in August 2022, Swan experienced a security incident when a third-party vendor was compromised in a phishing attack, exposing client email addresses and other identifying data. In August 2023, Fortress experienced a security incident in which a third-party vendor tool was compromised, resulting in the theft of approximately $14 million in digital assets from customer accounts. Terzaghi alleges that despite these events, neither Swan nor Fortress provided her with effective notification, customer protections, or fraud mitigation measures.

Terzaghi further claims that she contacted Swan through its official online help and support page seeking assistance to transfer her Bitcoin off Swan and secure it in her own Trezor hardware wallet. Subsequently, she received a telephone call from an individual who represented himself as Swan support. Relying on the representations and insider-level knowledge demonstrated by the caller, she followed the instructions provided, which resulted in the caller obtaining control of her wallet and executing unauthorized transactions.

The complaint alleges that Swan failed to coordinate internally and implement an effective account freeze, and showed reckless disregard for Terzaghi’s security after she had already been victimized. The unauthorized transfers were executed and processed through Cross River Bank, under the ownership and control of CRB.

Terzaghi seeks general and special damages, statutory damages, punitive and exemplary damages, restitution, disgorgement of wrongfully obtained monies, a declaratory judgment, injunctive relief, attorneys’ fees, costs of suit, and pre-judgment and post-judgment interest. She has also demanded a jury trial.
