Zalman Kass is an experienced commercial litigator with a specific focus on the financial industry and cryptocurrency. He is currently representing Dr. Craig Wright in a lawsuit that alleges he is the inventor of the crypto currency Bitcoin—and the blockchain itself— and that he has stolen half of the $22 billion fortune thus created. He is also representing 14 former bank directors, including the former chairman and president, in FDIC v. Galan-Alvarez, et al., a dispute in federal court for $257 million, arising from the FDIC’s takeover of R-G Premier Bank of Puerto Rico.

Zalman graduated from the Boston University School of Law and earned his undergraduate degree from Yeshivas Lubavitch. While in law school, he participated in both the Stone Moot Court Competition and the BU Civil Litigation Clinic. As a member of the clinic, he successfully represented indigent individuals in housing and employment disputes. He also interned at the Kings County District Attorney’s office prosecuting misdemeanor offenses on behalf of the county. Between undergrad and law school, he taught Judaic studies in Ukraine.

Prior to joining Rivero Mestre, he was awarded a public interest fellowship. As a legal fellow at the Legal Aid Service of Broward County, he represented clients facing eviction and the termination of their federal housing benefits.
