Grab is one of the most popular superapps in SE Asia and has a huge presence in payments – Taxi, Food, Wallet, P2P, P2M, Online Acceptance, Lending, Insurance, and Wealth. With bad actors, there is the potential loss of millions of dollars due to chargebacks, legal and reputational harm, potential loss of wallet licence, fines, and user trust loss.
