The expansion signals a shift in strategy for on-chain finance, aiming to provide allocators with the duration and active management capabilities standard in traditional markets. By integrating FBND, Plume is positioning its infrastructure to support more complex, yield-bearing assets rather than isolated, short-duration instruments. The move comes as the tokenized U.S. Treasury market climbs toward $15 billion, a figure that remains a tiny fraction of the $100 trillion global fixed-income sector.

Cynthia Lo Bessette, head of digital asset management at Fidelity Investments, emphasized that integrating tokenized assets into mainstream infrastructure requires deep collaboration. The vault offers investors increased programmability, allowing for the creation of custom portfolios and new methods of utilizing collateral. Plume, which already serves a significant portion of real-world asset holders, continues to build its ecosystem alongside established firms like Apollo Global Management and WisdomTree to bridge the gap between traditional institutional trust and blockchain efficiency.
