Plume has launched nBND, a tokenized fixed-income vault backed primarily by Fidelity Total Bond ETF (FBND). The product expands onchain access beyond short-duration Treasuries and cash equivalents, targeting institutional allocators seeking broader exposure to traditional fixed-income assets through blockchain infrastructure.

Plume, an Open Finance platform focused on institutional assets, has launched a new tokenized vault that uses Fidelity Total Bond ETF (FBND) as its primary reserve asset. Called nBND, the product is designed to expand the range of traditional fixed-income exposure available through onchain financial infrastructure.

The launch marks another step in the development of tokenized real-world assets (RWAs), but its significance is less about creating another blockchain-based yield product and more about broadening what can be represented and used onchain.

Early tokenized fixed-income markets have largely focused on short-duration U.S. Treasuries and money-market equivalents. Those assets have provided a relatively straightforward entry point for investors and financial institutions exploring tokenization. Plume argues that institutional markets will eventually require a wider range of fixed-income instruments, including assets with greater duration and active management.

The nBND vault is intended to address that demand by providing access to a tokenized structure backed by an established bond ETF. Fidelity Total Bond ETF invests across the U.S. investment-grade bond market, giving the product exposure to a broader fixed-income portfolio rather than a single category of short-term government securities.

That distinction matters as tokenized asset infrastructure moves beyond experimentation. Institutional investors typically manage diversified portfolios containing government bonds, corporate debt and other fixed-income instruments. If blockchain-based financial markets are eventually expected to replicate a meaningful portion of traditional capital markets, tokenization will need to support more than the simplest and most liquid instruments.

Plume CEO and co-founder Chris Yin described short-duration Treasuries and money-market assets as an initial stage for onchain fixed income, arguing that institutional allocators also require duration and active management.

The opportunity is substantial. According to data cited by Plume from RWA.xyz, the tokenized U.S. Treasury market grew from approximately $12 billion in April 2026 to $15 billion in June. Even at that level, tokenized Treasuries represent only a small portion of the global fixed-income market, which Plume cites at more than $100 trillion in assets.

The growth of tokenized government debt has attracted banks, asset managers, fintech companies and blockchain infrastructure providers. Firms including BlackRock, Franklin Templeton and other large financial institutions have already helped push tokenized funds and securities into mainstream financial-market discussions.

The next phase could involve bringing increasingly complex financial products onchain while retaining the governance, asset management and risk controls expected by institutional investors.

That requires cooperation between traditional financial institutions and crypto-native infrastructure providers. Asset managers bring portfolio-management expertise, regulatory experience and established investment products, while blockchain platforms can provide programmable ownership, automated settlement and composability.

Fidelity’s involvement illustrates that convergence. Cynthia Lo Bessette, head of Digital Asset Management at Fidelity Investments, said the company sees collaboration around tokenized assets as part of the development of mainstream market infrastructure. She also highlighted the potential for programmable financial products to support customized portfolios and new forms of collateral utility and access to capital.

Those potential use cases extend beyond simply allowing investors to hold a token representing a bond portfolio. Tokenized fixed-income assets could eventually become programmable collateral for lending, trading or other financial applications, although the practical deployment of such use cases depends on regulatory, liquidity and infrastructure considerations.

For GlobalFinTechEdge’s financial technology landscape, the development sits at the intersection of Blockchain Financial Technology, Digital Assets, Open Finance and Banking Technology Innovation. It also reflects the increasing overlap between traditional asset management and decentralized financial infrastructure.

There are still important limitations. Tokenizing an asset does not automatically create deep secondary-market liquidity, eliminate investment risk or make an underlying fund permissionless. Access, custody, regulatory treatment and the legal relationship between an onchain token and its underlying assets remain important considerations for institutional participants.

The nBND launch nevertheless demonstrates how the tokenization market is broadening its ambitions. The initial wave focused heavily on bringing cash-like instruments onto blockchains. The next challenge is creating infrastructure capable of supporting the diversity of assets found in conventional capital markets.

If that transition continues, tokenized fixed income could become less of a standalone crypto niche and more of a building block connecting traditional portfolios with programmable financial infrastructure.

Market Landscape

Tokenized real-world assets are moving from relatively simple cash and Treasury products toward broader fixed-income and capital-market instruments.

The market is increasingly attracting established asset managers, banks and blockchain infrastructure companies. The key challenge is now moving beyond token issuance toward deeper liquidity, institutional custody, regulatory clarity and practical collateral use.

Plume’s nBND launch fits this evolution by combining a traditional bond ETF with an onchain investment structure. It also illustrates the growing convergence between Open Finance, Digital Assets and conventional asset management.
