Castle says tokenization is only the start as RWA competition shifts to onchain utility
Castle Labs Research argues that the next phase of real-world asset adoption will be decided less by how many assets a network can list and more by whether those assets can function as productive capital onchain. In its latest report, the research team says tokenized treasuries, stocks, credit products and funds no longer stand out simply because they exist on a blockchain. What matters now is whether they can move across venues, tap deep liquidity, serve as collateral and plug into strategies that give users more than a digital wrapper of a traditional instrument. Using Mantle as its main case study, the report maps out how an RWA ecosystem can be built in stages: starting with infrastructure, then expanding asset listings, then improving execution quality and composability, and only after that leaning harder into user acquisition and distribution. Castle says Mantle currently carries more than $225 million in RWA assets, with over 60% in Mantle Index Four Fund, 21% in syrupUSDT, 15% in Ondo USDY and 2% in xStocks. The report also highlights changing market structure. With tokenized assets now available from platforms including Kraken, Robinhood, Crypto.com, xStocks, Backed, Securitize, Ondo, Franklin Templeton and BlackRock, simple issuance is no longer enough. Castle says the sharper test is whether RWA can become usable, mobile and yield-generating capital across CEXs, DeFi venues and wallets.
