ChainCatcher live report, HashKey RWA CEO Anna Liu delivered a keynote speech at the 2026 Hong Kong Web3 Carnival. She introduced that Hashkey Chain has deployed 11 tokenized products, with the total value of on-chain RWA assets reaching 2 billion Hong Kong dollars. The exchange has launched seven tokenized products, including Hong Kong's first tokenized gold ETF.She addressed the four major challenges of RWA: first, the authenticity of underlying assets; blockchain cannot guarantee the authenticity of data before it is on-chain, and the oracle problem is a core issue; second, the lack of a commercial closed loop; many projects go on-chain just for the sake of going on-chain, and new value must be created that traditional methods cannot achieve; third, the liquidity dilemma; even compliant STO exchanges in the U.S. often have daily trading volumes of only a few tens of thousands of dollars, requiring high-quality assets, licensed distribution channels, and secondary market infrastructure to be in place simultaneously; fourth, the complexity of cross-border compliance, suggesting that resource planning should be included from day one.She proposed that asset tokenization should first ask three questions: Can it be done? Is it suitable? Why tokenize? She cited data indicating that in the first quarter of this year, the global tokenized RWA market size has approached 30 billion dollars, growing over 260% in the past year, with the IMF characterizing it this month as "a fundamental restructuring of the financial architecture."
