The concept of RWA (Real World Assets) was very popular recently, but licensed exchanges have not expanded their RWA products, which are limited to the RWA cases of U.S. Treasury collateralized yield-bearing assets in DeFi. Recently, after BlackRock's deep involvement in Bitcoin spot ETFs, it also entered the RWA space, reigniting interest in RWA. However, since RWA is more focused on the B2B institutional market, how to design it for the B2C retail market? This issue still limits the expansion of RWA.
