What it returns

The total value of every stablecoin on one chain today, in USD, split by the currency each is pegged to, and the single largest stablecoin on the chain with its share. The figures are for 00:00 UTC of the day in timestamp. dominant is null when only the chain total and its split could be read. For a related daily series of the chain's stablecoin supply, which on some chains counts more coins than this total, use GET /stablecoin-analysis/stablecoin-supply-history/{chain}.
