Chambers & Partners Recognizes Fintech and Crypto Assets Practice, Co-Chairs Laurel Loomis Rimon and Kayvan Sadeghi in 2026 Fintech Guide

Chambers & Partners has again ranked Jenner & Block as a leading firm for Crypto-Asset Disputes in their 2026 Fintech Guide. Laurel Loomis Rimon and Kayvan Sadeghi, Co-Chairs of the firm’s Fintech and Crypto Assets Practice, also continue to be recognized individually for Crypto-Asset Disputes. This annual guide highlights the top fintech firms, advisers, and litigators in the United States and is based on thousands of in-depth interviews with clients.

In the guide, Chambers highlighted Jenner's strong white-collar criminal defense capabilities and our success advising blockchain and crypto-asset clients on securities class actions, fraud allegations, government investigations and litigation matters. Clients praised Jenner’s skill in highly technical litigation, noting that the firm is “communicative, great advocates, and work in very technical litigation." The guide also highlighted client feedback that the team has “extraordinary preparation for testimony and representation in government interview, and a strong perspective on what matters."

Laurel is a former federal prosecutor with deep experience in the financial regulatory and enforcement sector. She offers clients practical advice when facing compliance or enforcement challenges involving anti-money laundering, consumer protection, federal or state oversight, fintech, and payments. Laurel has been a leading practitioner and thought leader in the blockchain ecosystem for many years, having handled the first federal digital currency litigation. Clients noted that "Laurel is a terrific strategist and partner throughout a complex engagement. She is practical, responsive and kind, which are all important qualities in a sticky situation."

Kayvan serves as lead counsel for defendants and sophisticated plaintiffs in complex commercial and securities litigation nationwide, often involving nine- or 10-figure damages. He also advises a broad spectrum of clients throughout the crypto industry, helping them navigate the ever-changing legal landscape. Clients noted that "Kayvan is very deep in crypto and he understands technology and the market. He gets the nuances that are important and he has the depth and expertise," and that "Kayvan is a brilliant crypto litigator and adviser."
