Plume Launches nBND Vault: Bringing Fidelity’s Total Bond ETF Onchain for Institutional Allocators

Plume has launched its nBND vault, the first tokenized investment vehicle backed by the Fidelity Total Bond ETF (FBND) as its primary reserve. This move signals a shift from simple treasury-backed tokens to complex, actively managed fixed-income products on-chain, offering institutional allocators the duration and professional management they require for sophisticated portfolio construction.

What was announced

The nBND vault is a product of Plume’s flagship asset management protocol, Plume Nest Vaults. It is designed specifically for institutional allocators who seek to move beyond short-duration instruments like Treasuries and money market equivalents into more diverse, battle-tested assets. By using the Fidelity Total Bond ETF (FBND) as the underlying reserve, the vault provides exposure to a broader spectrum of the fixed-income market while maintaining the technical advantages of blockchain infrastructure, such as programmability and 24/7 accessibility.

The launch comes at a time of rapid expansion for the tokenized real-world asset (RWA) sector. Data indicates that the tokenized U.S. treasuries market surged from $12 billion in April 2026 to $15 billion by June 2026. However, this represents only a small portion of the global fixed-income market, which is valued at over $100 trillion. Plume aims to bridge this gap by offering compliant, non-custodial vaults that allow institutional capital to access yield-bearing assets. The nBND vault functions as a building block for a robust on-chain fixed-income market, rather than an isolated yield opportunity. It leverages Plume's status as an SEC-registered transfer agent, via Kimber Transfer Agency LLC, to ensure that these digital representations of traditional assets meet necessary regulatory standards for institutional participation.

"As tokenized assets and on-chain applications become more integrated into mainstream market infrastructure, a collaborative ecosystem is essential to expanding investment access. We're excited to collaborate with Plume to bring financial products on-chain, providing a broader set of investors with access to greater programmability to build custom portfolios, alongside investment solutions that unlock new forms of collateral utility and access to capital."

Cynthia Lo Bessette, Head of Digital Asset Management at Fidelity Investments.

The companies involved

Plume, also known as Plume Network, positions itself as an Institutional Open Finance platform. It currently serves more than half of all real-world asset holders by facilitating the transition of institutional assets from closed financial systems into open, globally accessible markets. The company’s Plume Nest Vaults protocol already features assets from major firms including Apollo, WisdomTree, and Hamilton Lane. Plume is backed by significant industry players such as Apollo Global Management, Galaxy Digital, and Brevan Howard, providing it with a strong foundation in both the crypto-native and traditional financial sectors. It maintains a regulatory foothold through an SEC transfer-agent registration via Kimber Transfer Agency LLC.

Fidelity Investments is one of the world's largest asset managers, with a long-standing reputation in traditional finance that it is now extending into the digital asset space. Through its digital asset management arm, the firm is increasingly involved in bridging the gap between legacy financial products and blockchain technology. The collaboration with Plume represents a significant step for Fidelity in making its established ETF products available as on-chain collateral and investment vehicles, reflecting a broader institutional trend toward the tokenization of traditional securities.

What this means

The tokenization of a Fidelity ETF marks a pivot point for the RWA sector. For years, "tokenization" was synonymous with stablecoins or short-term T-bills, which offered safety but lacked the duration and active management required for complex institutional strategies. By bringing a total bond fund on-chain, the industry is finally addressing the "duration gap" that has kept significant institutional capital on the sidelines. This puts pressure on other major asset managers to either provide their own on-chain vehicles or risk losing out to early movers who are defining the standards for digital collateral. The move suggests that the technical infrastructure of blockchain is finally being viewed not as a separate asset class, but as a superior delivery mechanism for traditional financial products.
