Despite significant growth in tokenized real-world assets (RWAs), a lack of dedicated secondary markets is hindering broader adoption, according to Prometheum CEO Aaron Kaplan. While regulatory ambiguity may impede some projects, the main obstacle lies in creating efficient platforms for buying and selling these securities. 2023 saw a surge in RWA value, driven by applications in private credit and US Treasury debt, although market infrastructure remains limited. Kaplan highlights two potential approaches: using decentralized finance (DeFi) frameworks like those employed by Ondo Finance and Ethena Labs or integrating tokenization protocols into established brokerage platforms with SEC-registered status.
