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.

Why it matters

This is the FX layer beneath DDD.

DDD tracks digital-dollar dominance against U.S. money supply. 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 dollar dominance as a macro benchmark from the slower question of whether non-dollar fiat rails are actually starting to matter onchain.
