Most blockchains are designed to maximize activity. More transactions, more competition, more variables interacting in unpredictable ways. That model works well for markets, where volatility and flexibility are features rather than liabilities. It becomes far less comfortable when the primary asset being moved is money. Stablecoins already behave like currency, yet the infrastructure beneath them often behaves like a trading environment. Plasma XPL is built around a different constraint. Gasless stablecoin transfers remove unnecessary exposure. Sub-second finality removes settlement ambiguity. Bitcoin-anchored security removes long-term drift. The objective is not speed or hype, but predictability. Markets reward motion. Infrastructure rewards dependability.
