Who Holds the Funds, Who Bears the Rules: The Regulatory Fight Over Stablecoin Dollar Accounts
A TechFlowPost opinion article by Bitget Wallet researcher Emily Sun argues that the real battle in next-generation dollar accounts is no longer about app design or payment convenience, but about legal ownership of user funds once dollars move outside the banking system. The piece uses the July 2026 controversy over KAST’s terms of service as a case study. Under the structure described in the article, a user’s USDC top-up was defined as a “sale” rather than a deposit, shifting ownership of the funds to the company and leaving users with a claim against KAST instead of direct ownership of assets. Sun says that distinction matters most in stress scenarios such as a liquidity event or bankruptcy, when users may rank as creditors rather than asset owners. The article contrasts that model with structures used by products including Ether.fi Cash, Plasma, Avici and Bitget Wallet, which aim to keep assets under user control while splitting wallet, card-account and payment-network functions across separate regulated entities. It also reviews how the U.S., Europe, Brazil, India, Singapore and Hong Kong approach stablecoin oversight. Across those regimes, Sun’s central claim is consistent: regulators care less about wallet software itself and more about who controls the money and whose balance sheet it sits on. As stablecoin supply expands, she argues, the defining question for digital dollar accounts will be who can aggregate many forms of on-chain dollars into one trusted user experience without quietly taking ownership of customer funds.
