Interpretation

The benchmark read is unambiguous.

USD rails define the market.

At 99.7%, USD-denominated rails effectively are the market right now. Non-USD assets exist, but they remain rounding-error small in aggregate share terms.

This is the FX layer beneath DDD.

DDD tracks USD stablecoin supply against U.S. M2. This board answers a different question: how on-chain fiat supply is split across currencies once it is already on public rails.

Together, the two views separate the stablecoin-to-M2 benchmark from the slower question of whether non-dollar fiat rails are starting to matter on-chain.

Since the on-chain fiat layer is currently 99.7% USD-denominated, U.S. M2 is the relevant denominator for the DDD benchmark. That comparison does not claim stablecoins are part of M2.
