In digital finance, Mei has deep regulatory and market knowledge across the niche areas of payments, cryptocurrency and blockchain, online lending, and other forms of fintech.

In cryptocurrency and blockchain, Mei advises some of the world’s leading cryptocurrency exchanges and US and European-based crypto firms on the regulatory and legal aspects of spot and derivatives trading, stablecoins, tokenization, token use cases, crypto on-ramp and off-ramp, blockchain networks, DeFi, and capital controls. Most recently, she advised OSL Group Limited on its acquisition of KoinSayang, through which OSL secured licenses for both spot and derivatives digital asset trading in Indonesia. She has also advised a widely diversified Indonesian business group on its strategic alliance with an American cryptocurrency exchange.

In other work, she has helped incorporate a number of pioneers in the Indonesian fintech market, including an insurance aggregator, an investment platform for foreign stocks through commodities derivatives, and a robo-advisory.

On the policy front, she assisted the Indonesian Fintech Association (AFTECH), an industry association officially recognized by the Financial Services Authority (OJK), in preparing codes of conduct and policy papers for the OJK.

She has also advised on industry-wide enforceability and close-out netting opinions for a leading global derivatives industry association. Her work also extends to cross-border cash-pooling arrangements, on which she advises international banks and multinational groups as to structuring and enforceability in Indonesia.

For market infrastructure, she helped a UK-based stock exchange establish Indonesia’s first market infrastructure for money markets. In securitisation, she has advised an e-commerce giant on asset-backed securities transactions that rely on “buy now, pay later” (BNPL) loans as the underlying instruments.

In sustainable finance and impact investment, Mei advises development finance institutions and impact investors, including the International Finance Corporation (IFC). Reflecting this work, in 2025 she was selected as one of 13 lawyers from across the Asia-Pacific region for the inaugural Impact Legal Fellows Program, a pioneering collaboration between the IFC and NYU Law’s Grunin Center for Law and Social Entrepreneurship, held in New York. The program, which examines the pivotal role of lawyers in building resilient markets and advancing impact investing, continues to this day.

In fund and investment management, she advises on the regulatory aspects of custodial and collateral management, securities derivatives, shareholding disclosure requirements, securities marketing rules, and financial-institution licensing and ongoing compliance requirements.
