Plume Launches Tokenized Bond Vault Backed by Fidelity ETF

Plume has introduced nBND, a tokenized bond vault backed by Fidelity’s Total Bond ETF (FBND), expanding access to fixed-income assets on the blockchain. This launch represents a shift from the previous focus on short-duration Treasuries, offering investors a broader range of bond exposures, including investment-grade, high-yield, and emerging market debt.

The nBND vault is part of Plume’s growing suite of tokenized assets, designed to integrate traditional financial products with blockchain infrastructure. Fidelity’s FBND, an actively managed ETF, provides the underlying asset for nBND, enabling on-chain investors to access diversified bond portfolios through tokenized formats.

Plume and Fidelity emphasize the potential of this collaboration to merge blockchain technology with traditional investment expertise. Cynthia Lo Bessette, Head of Digital Asset Management at Fidelity, and Plume co-founder Teddy Pornprinya discussed how investment solutions are increasingly moving onto blockchain networks, highlighting benefits such as programmability and expanded portfolio-building capabilities.

The tokenized U.S. Treasury market has seen significant growth, rising from $12 billion in April to $15 billion in June 2026, reflecting increasing interest in fixed-income blockchain products. Despite this growth, tokenized Treasuries remain a small fraction of the global $100 trillion fixed-income market, suggesting substantial opportunities for further tokenization.
