Coinbase and Major Networks Expand Stablecoin Payment Infrastructure

Major payment networks and infrastructure providers are accelerating their integration of stablecoins into global financial systems, with Coinbase evaluating participation in a new joint stablecoin platform alongside Stripe, Visa, and Mastercard [1]. This shift follows a period of significant industry investment, including Stripe’s $1.1 billion acquisition of Bridge and Mastercard’s purchase of BVNK [1, 3].

Key takeaways

• Coinbase is currently evaluating whether to join a joint stablecoin platform being developed by Stripe, Visa, and Mastercard [1].
• Mastercard has announced plans to support multiple regulated digital dollars, including USDC, PYUSD, and USDG [1].
• Coinbase has expanded its strategy to include reserve management, recently investing in ProShares’ IQMM ETF to align with GENIUS Act requirements [2].
• While stablecoins currently represent less than 1% of global cross-border payment volume, the total addressable market is estimated at over $17.9 trillion [3].

Building the Full Stack for Digital Assets

The push toward stablecoin adoption involves more than just payment processing; companies are now focusing on the underlying infrastructure required for reserve management and settlement [2]. Coinbase is positioning itself to provide a "full stack" of services, ranging from developer tools and distribution to the management of assets backing stablecoins [2]. By investing in ProShares’ IQMM ETF, which holds short-term U.S. Treasuries, Coinbase aims to support the liquidity and reserve standards mandated by the GENIUS Act [2].

Simultaneously, traditional payment giants are vertically integrating blockchain solutions to bridge the gap between fiat and digital currencies [3]. Mastercard’s acquisition of BVNK is intended to integrate blockchain-based settlement into the Mastercard Move network, aiming to make the transition between fiat and digital assets seamless [3]. These developments are occurring as corporate compliance officers become increasingly comfortable with stablecoin technology, though businesses remain cautious about holding digital assets directly on their balance sheets [3].

Why it matters

The industry is moving from theoretical discussions toward practical implementation, driven by the need for faster, around-the-clock settlement in cross-border B2B payments [2, 3]. While the GENIUS Act provides a regulatory framework that encourages the use of high-quality liquid assets for reserves, the path forward remains tied to ongoing legislative efforts like the Clarity Act [2, 3]. As Coinbase and its peers continue to build out these rails, the focus remains on mitigating reputational and compliance risks to ensure stablecoins can function as a reliable component of mainstream financial infrastructure [2, 3].
