Welcoming Diana Miller as Global Head of Litigation, Regulatory Enforcement & Investigations
Today, we are pleased to announce that Diana Miller has been appointed OKX's Global Head of Litigation, Regulatory Enforcement and Investigations. Diana brings extensive experience at the intersection of financial services, regulatory enforcement, and complex investigations. She most recently served as Managing Director and Head of US Litigation, Regulatory Enforcement, and Investigations at HSBC North America. Before that, she was Head of North America Regulatory Investigations and Enforcement for Citi’s institutional businesses, where she oversaw high-stakes matters across multiple regulatory regimes. Diana began her legal career at a premier global law firm that specializes in finance, capital markets, and financial regulation. She holds a J.D. from the University of Michigan and a B.A. from the University of Pennsylvania. Her appointment reflects something fundamental about who we are and where we are going as a company.
Building Trust Through Discipline
At OKX, we have made a clear choice: to build for the long term. That means governance, accountability, and a zero-tolerance approach to misconduct are not peripheral functions. They are core to our operating model. As digital assets continue to scale globally, scrutiny increases. Compliance with regulatory inquiries, and collaboration with law enforcement on cross-border investigations are part of operating responsibly in a complex financial ecosystem. Diana’s role is to ensure that OKX approaches these matters with rigor, transparency, and discipline. She will lead our global strategy across litigation, regulatory enforcement matters, and help manage our relationships with global law enforcement agencies, working closely with our Legal, Compliance, Risk, and Executive teams to ensure consistent standards across jurisdictions.
A Proven Leader in Complex Regulatory Environments
Diana has built and led litigation and investigations teams inside two of the world’s largest financial institutions. She understands what it means to operate under intense regulatory supervision, manage multi-agency enforcement matters, and uphold the highest standards of governance. Her experience across banking and the global financial system brings valuable perspective to the digital asset industry as it continues to mature and integrate with traditional financial institutions.
Strengthening Law Enforcement Partnerships
OKX works closely with law enforcement agencies around the world. We respond to tens of thousands of law enforcement requests annually, cooperate with authorities across more than 100 jurisdictions, and maintain dedicated teams focused on supporting investigations. Our approach is simple: when credible risks are identified, we act swiftly. We restrict accounts, freeze assets when appropriate, and provide information in accordance with the law. We invest heavily in transaction monitoring, on-chain analytics, and partnerships with leading intelligence providers to detect and deter illicit activity.This commitment has made a real difference. In 2025, OKX played a critical role in what became one of the largest crypto scam recoveries to date. Through proactive monitoring and close coordination with partners and law enforcement, approximately $225 million in illicit proceeds linked to a coordinated scam network were identified and ultimately seized. Our teams provided timely intelligence and data that helped authorities trace complex laundering patterns across dozens of accounts and intermediary wallets. Cases like this underscore a broader truth: digital assets can be misused, but they are also traceable, transparent, and recoverable when platforms and authorities work together. And OKX's collaboration with global law enforcement is only increasing, as we continue to build out not only our bench of talent with leaders like Diana, but also through a meaningful commitment of resources to develop cutting-edge, AI-driven technology, enabling us to investigate scams faster and more comprehensively than ever before.In the past 12 months alone, OKX has been integral in identifying or tracing more than $275 million in illicit funds, and responding to over 27,000 requests from law enforcement agencies from across the globe.
$47M Seizure by APAC LE. OKX identified victim deposit addresses, scam-controlled wallets, and a consolidation point where $46.9 million in USDT was pooled, to lead to a successful seizure of $47M (see https://www.okx.com/en-gb/learn/our-commitment-to-security for more).
$3.7M Seizure by Bangladesh LE. Our collaboration with the Bangladesh Criminal Investigation Department led to the freeze and seizure of approximately $3.7M USDT connected to Metaverse Foreign Exchange Group, a Ponzi scheme flagged by financial regulators around the world (including the UK FCA, Canadian OSC). It is believed to have affected more than 500,000 victims across the globe. (see How money laundering probe led to seizure of Tk45cr cryptocurrency for more information).
$17M Seizure by Ghana LE. OKX also proactively assisted the Economic and Organised Crime Office of Ghana and the UK National Crime Agency with freezing and seizing approximately $17M worth of virtual assets connected to the Chymall Ponzi scheme. This case is the perfect exemplar of what cross-border private-public cooperation can achieve.
Under Diana's leadership, our investigations team will further strengthen this collaboration. Her background in regulatory enforcement and cross-border investigations will enhance our ability to engage constructively with global agencies. And her extensive procedural experience will ensure that our internal processes - and the teams that manage them - meet the highest standards.
Part of a Broader Commitment to Security and Integrity
Diana joins at a time when OKX continues to deepen its investment in governance, risk management, and security.We have built a layered compliance framework combining experienced professionals, real-time transaction monitoring, advanced analytics, and global partnerships. We maintain a strong culture of cooperation with law enforcement and a clear stance against the misuse of our platform. We also continue to invest in transparency measures such as Proof of Reserves, robust custody architecture, and continuous improvement of our financial crime controls.This is not about checking boxes. It is about building an institution that can endure.
Looking Ahead
As the digital asset ecosystem evolves, so too must its legal and governance frameworks. We believe the future of crypto belongs to platforms that operate with discipline, respect the rule of law, and build trust with regulators, partners, and users alike.Diana’s appointment reinforces that belief. Please join us in welcoming Diana Miller to OKX. Her experience, judgment, and commitment to integrity will play a central role in helping us continue to build a secure, trusted, and globally respected digital asset platform.
