Plume Brings Fidelity’s Total Bond ETF Onchain Through nBND

Plume has launched nBND, a tokenized vault primarily backed by shares of Fidelity Total Bond ETF (FBND), extending onchain fixed income beyond the Treasury and money-market products that have dominated tokenized markets. FBND is an actively managed U.S. bond ETF investing across government debt, investment-grade and high-yield credit, mortgages and emerging markets, with an expense ratio of 0.36%. Plume says the structure gives investors access to duration and active management through blockchain-based infrastructure. The widely cited $28 billion figure refers to FBND’s total assets, not assets deposited into nBND, and Plume has not disclosed the vault’s launch size. The company said nBND is the first step in a broader Fidelity collaboration, with additional assets potentially moving onchain over time.
