Key Highlights:
- Plume has launched a structure tied to Fidelity’s actively managed FBND exchange-traded fund, aiming to expand real-world asset tokenization beyond short-duration Treasury bills.
- The onchain instrument, dubbed nBND or nFBND, is a receipt token issued by Nest DAO LLC rather than direct registered ownership of Fidelity’s nearly $28 billion fund.
- Despite the massive size of the underlying traditional ETF, DeFi tracking data on DefiLlama recorded an initial onchain balance of roughly $48 shortly after debut.
Plume Expands Real-World Asset Strategy to Active Fixed Income
The onchain fixed-income landscape has long remained tethered to cash equivalents and short-dated sovereign debt. Real-world asset (RWA) blockchain Plume is now attempting to shift that narrative by integrating longer-duration, actively managed funds into decentralized finance infrastructure. The initiative focuses on the Fidelity Total Bond ETF (FBND), a cornerstone product from traditional finance giant Fidelity Investments.
Plume’s leadership contends that institutional participants require more sophisticated instruments than the basic cash management tools currently dominating crypto markets. Highlighting this shift, Plume CEO and co-founder Chris Yin emphasized the demand for traditional portfolio structures onchain. “While the onchain fixed income market was originally concentrated in short-duration Treasuries and money market equivalents, these are the starting points, not the destination. Institutional allocators want duration, and active management, the same building blocks they use offchain,”
Plume CEO and co-founder Chris Yin said on Monday.
Inside the Mechanics: Translating Fidelity’s FBND to Blockchain Plumbing
Originally introduced by Fidelity in October 2014, FBND offers substantial duration compared to typical tokenized cash vehicles. Fidelity’s data from June placed the fund’s net assets at $26.6 billion, with third-party projections rising to near $28 billion by early October. A quarterly review of FBND revealed approximately six years of duration, a 4.74% 30-day SEC yield, and an investment strategy weighted heavily toward investment-grade corporate and sovereign debt.
Rather than developing a synthetic or crypto-native alternative, the initiative connects an established, conventional debt portfolio to decentralized ledgers. Cynthia Lo Bessette, Fidelity Investments’ head of digital asset management, noted the broader institutional vision, stating that Fidelity is working with Plume “to bring financial products on-chain,”
pointing to programmable portfolios, collateral utility, and access to capital.
Receipt Tokens vs. Underlying Reserves: Context Behind the $48 Launch
Despite headlines referencing the multi-billion-dollar fund, the structural reality involves specific nuances. The asset—designated as nBND or nFBND—operates as a vault receipt token issued by Nest DAO LLC. Investors participating in the vault structure do not become direct, registered shareholders of Fidelity’s FBND, nor has Fidelity relocated its underlying fixed-income positions onto the Plume Mainnet.
Early reception prompted scrutiny over circulating metrics. While FBND commands nearly $28 billion in traditional markets, tracking platform DefiLlama classified nFBND as a wrapper and receipt token issued by Nest DAO LLC, logging just about $48 in onchain assets shortly after deployment. While modest, the underlying thesis focuses on utility: turning a diversified, managed bond fund into programmable collateral that can navigate decentralized finance ecosystems while the primary assets remain within conventional custodial frameworks.
Plume continues to draw institutional interest, supported by backing from industry participants including Apollo Global Management, Galaxy, Brevan Howard, and Haun Ventures, while collaborator Nest maintains operational vaults for Treasury bills and private credit instruments.
Why This Matters
The vast majority of tokenized real-world assets have congregated around risk-free, short-term yields, particularly U.S. Treasury bills. By introducing an instrument connected to an actively managed, intermediate-duration ETF like FBND, Plume is attempting to establish the infrastructure necessary for complex institutional portfolio management on blockchain rails. While the initial capital committed onchain stands at a nominal figure, the model could serve as a testing ground for how institutional asset managers employ programmable collateral without dismantling traditional custodial safekeeping.
Frequently Asked Questions
What is the difference between FBND and nFBND?
FBND is an actively managed exchange-traded fund launched by Fidelity Investments in traditional financial markets holding nearly $28 billion in assets. nFBND (or nBND) is an onchain receipt token issued through a vault run by Nest DAO LLC on the Plume network; it does not grant direct shareholder registration in Fidelity’s fund.
Why are Plume and Fidelity focusing on actively managed bond ETFs?
Most existing tokenized fixed-income products offer exposure exclusively to short-term Treasuries. Integrating an instrument linked to FBND introduces duration and active credit management, providing the traditional building blocks institutional allocators typically use in offchain asset strategies.
How much capital was originally committed to the nFBND token?
According to metrics recorded by DefiLlama shortly after the wrapper’s debut, the onchain vault initially recorded approximately $48 in total value, standing in stark contrast to the nearly $28 billion managed by the underlying traditional fund offchain.
