GDX token vs the real share
GDXx on Solana against the ordinary GDX share, sampled every 15 minutes.
Read this one carefully. The GDXx price did not change once across the window — an AMM quote only moves when somebody swaps, so this is the price of the last trade, not a live market.

The perps on GDX price off the ordinary share — marks sit within about 0.10–0.15% of it — while the long leg of the carry is bought as a token on Solana. So this gap is not a curiosity: it is the entry cost of the position, charged in full on the way in. Buying at a discount is a rebate if the gap closes before you exit and a loss if it widens, which is precisely the question this series was started to settle. "Distinct token prices" is the quickest sanity check available: if the count is 1, nothing traded and the number above is a leftover quote.
Samples land every 15 minutes and are kept 90 days. Readings beyond ±20% are never recorded — past that it is a broken pool quote, not a basis.
