The payment industry may seem "old," but it has always been the earliest and most easily restructured part of the financial system through technology.
While the market continues to debate whether "cryptocurrency is an asset," the two payment giants—Visa and Mastercard—have reached a consensus on a more fundamental engineering question: Is there a more efficient settlement layer that can be embedded into the existing payment system, rather than starting from scratch?
The answer is stablecoins.
Recently, Visa announced the use of Solana to open USDC settlements to banks in the United States. Prior to this, Mastercard partnered with Ripple to test RLUSD-based transaction settlements on the XRPL.
This is not a short-term pilot but rather a clear signal of the global payment infrastructure beginning to migrate toward a new generation of settlement layers.
Visa: Turning Stablecoins into a "Settlement Plugin"
Visa's moves may seem cutting-edge, but their logic remains highly restrained.
It did not choose to build a closed blockchain system but instead directly integrated the Solana network and USDC stablecoin into its settlement backend as an available option within the existing clearing process.
Key data: In the United States, institutions like Cross River Bank have already begun using USDC for settlements via Solana. Visa disclosed an annualized settlement run rate exceeding $3.5 billion.
Seamless experience: For consumers, the card-swiping experience remains unchanged.
For banks, the change is highly intuitive: the traditional T+1/T+2 clearing cycle, limited to weekdays, has been compressed into 24/7 continuous settlement, significantly reducing funds in transit and liquidity occupancy.
Notably, Visa has not packaged this capability as a "financial paradigm shift" or "disruptive innovation." It repeatedly emphasizes standardization and productization—treating stablecoin settlement as a deployable, replicable foundational capability.
This also explains Visa's recent launch of stablecoin consulting services: its goal is not to push banks "toward crypto" but to help them understand and integrate next-generation settlement tools.
In this system, stablecoins are not standalone financial products but rather foundational modules embedded within the payment network.
Mastercard: Building a "Compliant Connectivity Layer"
Unlike Visa's "direct connection to public chains," Mastercard has chosen a more complex path of "alliances and partnerships."
Multi-chain collaboration: It has not bet on a single path but has instead worked with Ripple (XRPL), Gemini, and institutions in the Middle East.
Compliance puzzle: It prefers to build a "pluggable compliant connectivity layer."
Mastercard's self-positioning is very clear: it does not seek to become an extension of any single public chain but instead places itself at the interface between the traditional financial system and on-chain settlement networks.
The core advantage of this architecture lies in its flexibility—regardless of which stablecoin or technical path becomes mainstream in the future, Mastercard can quickly integrate through connection and adaptation. This model is particularly suitable for cross-border payments, B2B settlements, and RWA scenarios that are structurally complex and require high compliance.
The Battle for the Settlement Layer Points to a $40 Trillion Redistribution
Despite their different paths, Visa and Mastercard are highly aligned on one key judgment.
What they are truly focused on is not the growth of a single stablecoin's scale but whether future settlement activities will break away from the existing payment network and complete closed loops on new technological layers.
Once fund flows can achieve peer-to-peer settlements on-chain, the intermediary value of traditional clearing networks will be reassessed. This is precisely why the two major card networks must intervene early and define their positions clearly.
Visa's latest report mentioning that "stablecoins could reshape the global $40 trillion credit market" is not merely a narrative of scale but a structural judgment: when settlement tools become programmable, the underlying logic of credit issuance, risk control, and fund allocation will adjust accordingly.
Whoever controls the settlement layer is closer to defining the rules of next-generation fund flows.
This is a revolution happening outside the public eye.
It is not a user-facing celebration but a technical migration occurring in backend systems: quiet, gradual, but once completed, almost irreversible.
When the world's largest payment networks begin to view on-chain settlement as a foundational capability, blockchain is no longer an external variable of the financial system but is becoming part of its internal engineering.
Payments may still look the same, but the underlying settlement logic is entering a new technological phase.
