Binance.US, the American arm of the world's largest cryptocurrency exchange by trading volume, has named a new chief compliance officer.

Binance.US said it hired Lesley O'Neill, who most recently served as chief compliance officer at Prove Identity, a digital identity verification platform that serves banks, financial services companies, and e-commerce merchants, among others.

Lesley O'Neill replaces Tammy Weinrib

O'Neill joined Binance.US this week and replaced Binance.US's previous compliance chief, Tammy Weinrib, a company spokesperson told The Block. Weinrib left Binance.US in November, according to her LinkedIn profile. In that month, Binance and its founder Changpeng "CZ" Zhao pleaded guilty to anti-money laundering and sanctions violations and agreed to pay $4.3 billion and $50 million in fines, respectively. While Binance.US was not part of Binance's settlement, it faces an enforcement action by the Securities and Exchange Commission for allegedly offering unregistered securities to U.S. investors. The case, involving Binance and Zhao, is ongoing. Additionally, the SEC is reportedly still also investigating whether Binance and Zhao may have a backdoor to control assets stored on Binance.US.

O'Neill brings to her new role more than 15 years of experience related to regulatory and privacy compliance, information security, and identity verification and authentication to Binance.US., the company said. Before Prove, O'Neill worked at Ernst & Young, Milbank and Bloomberg.

O'Neill's experience "partnering with crypto companies to enhance their AML and KYC processes at Prove, as well as her work in traditional financial services at Ernst & Young, will be exceptionally valuable as we continue to uphold the highest standards of compliance, safety, and security on our platform," Norman Reed, Binance.US's interim CEO said in a statement.
