Recently, DBS Bank in Singapore announced the launch of tokenized structured notes operating on the Ethereum public blockchain, expanding the public's access to blockchain financial products. This is an important extension of DBS Bank's Project Guardian pilot program, transitioning from a permissioned blockchain to a public blockchain architecture, offering greater transparency and potential for global liquidity. This initiative may facilitate further integration between traditional banks and the digital asset market, thereby attracting a wider range of institutional and retail investors to participate in blockchain innovation.
