Stablecoins get the headlines, but someone has to move them. Polygon's payments stack has now processed more than $1 billion in annualized volume for two weeks running. TRON still carries a big share of everyday USDT spending, mostly because transfers there are cheap and fast. And Visa now settles stablecoin payments across nine blockchains instead of betting on just one. These networks are quietly turning into payment infrastructure, competing on fees and speed rather than hype. For someone paying at a checkout or sending money home, what matters is simple: how much it costs, how fast it lands, and whether the other side can receive it. The next stage of crypto payments may be decided less by which coin you hold, and more by which network moves it. What network do you use most for payments?
