TS-GMRI-ETF™
What it tracks
Filter. Tokens that wrap an existing exchange-traded fund (ETF) holding physical metals or metal-economy equities, rather than a single equity or a unit of physical metal.
Weighting. Market-cap weighted with 40% single-issuer cap.
A registered methodology slot for tokens that wrap an entire ETF rather than a single share or a gram of metal. The wrapper is a derivative-on-derivative (token → ETF share → underlying basket). Structurally distinct from both TS-GMRI (commodity-backed) and TS-GMRI-MEQ (equity), so it earns its own slot. Live example at registration: Backed Finance bGLD (wrap of SPDR Gold Shares GLD). Slot reserved 122 June 2026 for prior art; no value is published until N≥3 eligible constituents from ≥2 distinct issuers and ≥2 distinct underlying ETF strategies.
Tokenized ETF wrappers are a structurally new wrapper class with no conventional TradFi analog — existing commodity-ETF indices track underlyings, not derivative wrappers. Issuer pipeline visible: Backed Finance (additional wraps for GDX, SLV, URA planned), 21Shares + Securitize tokenized-ETF programme, Swarm Markets ETF tokens. Registering the slot now establishes prior art before the category becomes contested.
Constituents
0 / N≥3 eligible constituents from ≥2 distinct issuers and ≥2 distinct underlying ETF strategiesAwaiting tokens meeting eligibility (Section 3 of the methodology: physical-metal backing, on-chain claim, issuer transparency, ≥ USD 1M market cap, public price feed, no double-counting). Currently 0 eligible constituents.
The rules are fixed and the slot is registered for prior art. No value is published and no constituents are listed until the threshold is met — we do not invent numbers from sparse data.

The index is recomputed daily at 00:00 UTC from CoinGecko closing-day market caps. Let MCi,t be the circulating market capitalisation of constituent i on day t, and MCi,0 its value on the base date (22 June 2026, base value 100).
where ŵi are cap-weights after the iterative 20% single-issuer cap.
Both cap-weighted and equal-weighted variants are rounded to 2 decimal places for display. New constituents are chained in at the next monthly review using a continuity multiplier so the historical series is not distorted. The full rules are fixed in the methodology document below.

Disclaimers & notices
- Information product, not investment advice. TS-GMRI-ETF is a proprietary index published by TrueSource Metals for informational purposes. Nothing here is a recommendation to buy, sell or hold any token or instrument.
- Liquidity caveats. Liquidity in the underlying tokens is uneven; cap-weighted values are sensitive to large moves in the dominant tokens (e.g. XAUT and PAXG). Small-N cuts can swing on single-name moves.
- Short history. The series is live since 22 June 2026 — only a handful of days of history exist. Volatility, drawdown and risk statistics are not yet statistically meaningful and are deliberately omitted.
- Unaudited. The index is unaudited at v1.0.
