The stablecoin battle has shifted from "who issues the coin" to "who owns the rails." Total fiat-backed stablecoin supply hit $273B in March 2026. Real-world payment volume doubled last year to $400B — 60% of it B2B. Now AWS is embedding stablecoin payment rails into enterprise cloud infra so AI agents can pay for things autonomously in real time. ETH is right around $1,993 here — the settlement layer most of these flows still run through. If the infrastructure race is about compliance, custody, and connectivity, Ethereum has a structural edge. Who wins the stablecoin rails war — banks, fintechs, or native crypto protocols? Just sharing my thoughts. Not financial advice. DYOR. #StablecoinInfraRace #OKXOrbit
