Stablecoins are better suited for AI agent payments than credit cards. They mitigate the security risk of sharing card details and enable the programmatic creation of countless wallets for agent swarms. This allows for a future where every API call could be a micro-transaction paid with stablecoins.

The recent explosion of stablecoins wasn't due to a new financial innovation, but the maturation of underlying blockchain infrastructure. Cheaper and faster transactions on Layer 2 solutions and improved Layer 1s finally made large-scale, low-cost payments practical for real-world use.

The US government's backing of stablecoins is a strategic financial maneuver, not just a nod to crypto innovation. By promoting stablecoins backed by US Treasuries, it creates a new, frictionless global distribution channel to sell its debt at attractive rates to a worldwide audience.

Instead of funding another stablecoin protocol, the more viable investment is in the tooling layer. This includes payment systems, SDKs, and accounting software (like triple-entry bookkeeping) that enable small businesses globally to integrate stablecoin payments into their existing fiat workflows.

The primary, world-changing use case for stablecoins isn't cheaper domestic payments. It's providing global, frictionless access to the U.S. dollar. This allows citizens in countries with unstable currencies or untrustworthy central banks to opt-in to the U.S. financial system, effectively exporting America's most powerful product.

By embedding stablecoin wallets, companies can move beyond simple payouts. They can maintain an ongoing financial relationship, offering services like savings or credit directly to their user base (e.g., drivers, creators). This effectively allows any platform to build its own neobanking arm.

Before stablecoins, launching financial services in N countries required N² unique integrations. Now, companies can build on a single dollar-stablecoin standard and instantly operate globally. Adding other local stablecoins becomes a simple N-style addition, radically simplifying global expansion.

The primary strategic reason for a large platform to issue its own stablecoin isn't just yield, but control. Relying on an external stablecoin creates platform dependency, making the business vulnerable to changes in fees or strategy, much like Zynga's reliance on the Facebook platform.

Stablecoins will likely enter the US market not through domestic retail payments, but via international network effects, similar to WhatsApp. Initial US users will be those interacting with the global economy, and adoption will spread inward as these cross-border connections become more common.
