Stablecoin adoption has a measurement problem. A token moving between addresses does not necessarily mean a business payment occurred.
One supplier payment may create several onchain transfers as funds pass through wallets, networks, liquidity providers, and local settlement partners. At the same time, many customer payments may be grouped into a single transfer. Raw volume therefore shows movement, not purpose.
The better question is what economic task was completed: payroll, supplier settlement, treasury, remittance, or checkout. We should also look at repeat business usage, settlement time, failure rates, reconciliation, and conversion into local currency.
Stablecoins become real financial infrastructure when they complete useful work reliably—not simply when onchain volume reaches a larger number.
