Key Takeaways
- • Stablecoins processed an estimated $46 trillion in transaction volume in 2025, exceeding PayPal volume by 20x, approaching 3x Visa's volume, and nearing ACH network levels, establishing stablecoins as a material payment infrastructure.
- • A new generation of startups is solving the critical on/offramp problem by integrating stablecoins with local payment systems through cryptographic proofs, regional QR code networks, real-time payment rails, and interoperable wallet and card-issuing platforms.
- • Stablecoins enable sub-second settlement for under one cent per transaction, with mature on/offramps expected to unlock real-time cross-border worker payments and merchant acceptance without requiring traditional bank accounts.
- • The convergence of stablecoin infrastructure with mainstream payment systems is positioned to drive behavioral adoption, expanding digital dollar economy participation to underbanked populations and enabling global commerce at dramatically lower friction and cost.
Summary
Stablecoins have achieved substantial scale as a payments rail, with $46 trillion in transaction volume recorded in 2025—a metric that underscores their growing material importance to financial infrastructure. To contextualize this figure: the volume exceeds PayPal's annual transaction volume by more than 20x, approaches three times Visa's volume despite Visa's global dominance, and rapidly approaches the scale of ACH (Automated Clearing House), the core electronic network for financial transactions in the United States. This volume growth reflects accelerating adoption across both institutional and retail market segments.
The fundamental technical advantage of stablecoins—enabling settlement in under one second for less than one cent—has been proven and widely deployed. However, the critical infrastructure gap remains the connection between digital stablecoins and the existing financial rails that consumers and businesses rely on daily. This on/offramp problem has historically limited mainstream adoption by fragmenting the stablecoin ecosystem from traditional payment networks.
According to a16z crypto's 2026 trend analysis, a new generation of startups is directly addressing this gap through multiple technical and operational approaches. Some leverage cryptographic proofs to enable private conversion between local currency balances and digital dollars. Others integrate with regional payment networks that utilize QR codes and real-time payment rails to facilitate bank-to-bank transfers. Additional entrants are building interoperable global wallet layers and card-issuing platforms that allow end-users to spend stablecoins at everyday merchants, effectively bridging digital and legacy payment systems.
The maturation of these on/offramp solutions is expected to catalyze new economic behaviors and use cases. Once stablecoins integrate directly into local payment systems and merchant infrastructure, workers can receive real-time cross-border payments denominated in digital dollars, and merchants can accept global stablecoins without requiring traditional bank accounts. This capability targets underbanked populations and cross-border commerce participants, expanding addressable market participants significantly. The combination of stablecoin velocity, regulatory clarity, and improved on/offramp infrastructure is positioned to accelerate stablecoin penetration into mainstream payments during 2026.
