Plume (PLUME)

cryptobriefing.com reports that Plume has launched the Nest Fidelity Total Bond ETF Vault, known as nBND, to give institutional investors onchain access to Fidelity’s actively managed FBND bond fund. The vault operates on Nest, Plume’s protocol for packaging real-world assets, and issues a receipt token that serves as proof of claim on the underlying FBND shares. These tokens trade on Plume’s modular Layer-2 blockchain, allowing users to deposit stablecoins for programmable exposure without traditional brokerage routing.
Fidelity’s FBND ETF, which manages approximately $28 billion in assets, carries a 0.36% expense ratio and offers a yield of around 4.88%. The product emerged from a June 2026 partnership between Plume and ether.fi to build the Etherfi Liquid RWA vault, which started with $25 million and targets $100 million. Its holdings include allocations to BlackRock’s iShares AAA CLO ETF alongside Fidelity’s FBND.
Plume’s public mainnet, Plume Genesis, launched in June 2025, and the company obtained SEC transfer-agent registration in October 2025 to support tokenized securities. This registration helps maintain the official record of security ownership on the blockchain. The receipt token structure introduces smart contract and platform risks alongside standard bond market risks. Interest rate movements will continue to affect FBND’s value regardless of the chain hosting the token.
How the market reacted
Whalio's own Binance spot order flow for PLUME, measured when this story was written up on 5 October 2026. Not the outlet's figures.
Whalio data shows PLUME trading at $0.01886 with a 24-hour buy ratio of 56.0%, indicating that buying pressure has dominated the day. However, short-term sentiment has shifted, with the 1-hour buy ratio dropping to 26.5% and the 4-hour ratio at 40.6%, suggesting that immediate buying momentum is fading compared to the daily average. The 24-hour volume delta is positive at +$242,597, meaning net buying has outweighed selling over the full day. In contrast, the 1-hour and 4-hour volume deltas are negative, showing that recent trades have seen more selling than buying. The cumulative volume delta (CVD) for the 24-hour close stands at +$75,947, confirming that buyers have been in control for the majority of the session. Despite the recent dip in short-term ratios, the coin has seen net buying for 18 of the last 24 hours.
The latest daily buy ratio of 55.9% sits at the 96th percentile of the last 322 days, against a median of 49.4% - among the strongest buying days it has had.
Was that an ordinary day?
The same Binance spot measurements for PLUME, averaged over the days leading up to the story.
Over the preceding week, PLUME maintained a consistent buy ratio of 55.4%, which is nearly identical to the current 24-hour reading of 56.0%. This indicates that today’s trading activity is ordinary and aligns with the weekly average rather than representing an unusual spike. Volume remains subdued, with today’s spot volume of $2,029,147 sitting at 0.40x the weekly average, suggesting lower participation than usual. Despite the lower volume, the coin has experienced net buying for all seven days of the week. The total volume delta for the eight-day period is +$4,305,676, reflecting steady accumulation over time. Price has risen by 0.5% over the eight days, showing minimal but positive movement alongside the consistent buying pressure.
