How Stablecoins Are Replacing Payment Rails - Emilio Rivero Coello | ATC #591

Stablecoins have moved from niche experiments to a core component of global payments. In 2025, on‑chain stablecoin transactions exceed the daily volume of traditional card networks, with total market capitalization above $250 billion. Latin America, led by exchanges like Bitso, demonstrated early regulatory engagement, shaping frameworks that now guide institutions worldwide. This surge reflects growing confidence that stablecoins can provide fast, low‑cost settlement while maintaining fiat backing, positioning them as a viable alternative to legacy rails for both consumers and enterprises.

Aptos differentiates itself by delivering institutional‑grade performance: sub‑second finality, millions of transactions per second, and minimal gas fees. These metrics enable the network to support high‑volume stablecoin flows such as USD1, the native Aptos stablecoin, and integrations with major issuers like Tether, Circle, PayPal’s PayYUSD, and Paxos. Product teams focus on expanding transaction count, market‑cap supply, and diverse use cases, ranging from cross‑border B2B settlements to remittance services. By providing a scalable, low‑cost layer, Aptos allows financial institutions to bypass traditional correspondent banking, achieving faster settlement and lower operational costs.

Regulatory clarity is accelerating stablecoin adoption. The U.S. Stablecoin Act, Europe’s MiCA framework, and Singapore’s progressive guidelines define AML, reserve‑backing, and reporting standards, reducing compliance uncertainty for issuers and users. This environment encourages banks and fintechs to launch proprietary stablecoins tailored to specific markets, while tokenized real‑world assets—such as digitized deposits and money‑market funds—rely on stablecoins as the liquidity bridge. Emilio Rivero envisions a future where every financial asset is tokenized, enhancing capital efficiency and enabling seamless on‑chain and off‑chain flows, with stablecoins serving as the foundational money layer.
