Mastercard’s crypto partner push is actually a plan to keep stablecoins within its network
Mastercard is trying to ensure that the stablecoin era still needs its card services.
On Wednesday, the company launched a program with more than 85 crypto-native companies, payment providers, banks, compliance vendors, custodians, exchanges and infrastructure groups. At first glance, that reads like yet another ecosystem announcement.
However, let’s take a look at what the list entails. Mastercard is gathering the counterparties it needs so that when stablecoins, tokenized deposits and other digital dollar instruments become meaningful payment rails, these flows can still pass through Mastercard’s underwriting, trust and settlement layers rather than around them.
The affiliate program is essentially a public index page for infrastructure already under construction. Mastercard has spent years working on crypto card issuance, merchant acceptance tools, compliance checks, digital asset services, and tokenized settlement rails.
The new program bundles these pieces into a clearer field: digital assets can move faster and on more programmable rails, while regulated money movements and merchant access can still run through the existing network.
The real battle here is over who controls digital money once it starts moving in the form of fund transfers, seller settlements, payouts, government bond transfers, and flows from issuers and buyers. Stablecoins create the possibility of a cheaper or faster bypass around the traditional card economy. Mastercard’s answer appears to be to incorporate that side road into its own managed routes.
Additionally, on March 3, Mastercard and SoFi said they would enable SoFiUSD settlement through the Mastercard network. That was a more operational proof point than the broader partner rollout on March 11. It linked a so-called stablecoin to network settlement, which is much closer to real payments than an open-ended ecosystem explanation.
Taken together, the two announcements suggest that Mastercard is moving from “we support digital assets” language to specific settlement use cases with branded tools and defined network paths.
The new announcement is a wrapper around an older build
Mastercard’s latest move makes more sense when viewed as strategic packaging around an existing build. The company has been laying this foundation for years. In 2021, it rolled out a card program for cryptocurrency businesses, aiming to simplify issuance and launch more crypto-linked payment products.
That was an early sign that the company saw the risk of treating crypto as an external market to observe from a distance. It wanted to be the network used when crypto hit consumer payments.
Since then, Mastercard has expanded its stack of digital assets across multiple layers of the transaction chain. The broader overview of digital asset services highlights work in underwriting, card programs, settlement, identity and compliance. The networking materials describe a system intended to connect financial institutions and businesses in tokenized transactions.
In plain English: Mastercard has built payment systems for a world where some bank money and transaction settlements take place in blockchain form.
Therefore, the partner grid looks like a map of dependencies. A network trying to stay central to digital dollar flows needs blockchains to host assets, custodians to hold them, compliance firms to screen them, banks to issue or support them, processors to route them and a merchant-facing infrastructure to keep them operating in commerce.
The companies in Mastercard’s new program include these categories, making the list less of an indication of breadth and more of a feature map. It outlines the minimum coalition needed to keep money within the chain connected to trade outside the chain.
Mastercard is building the rails so that digital dollars can be settled, moved and reconciled behind the scenes, while merchants, banks and users continue to interact with familiar payment experiences. The visible consumer experience will therefore change little, even if the underlying financial flows become more blockchain-native.
A customer can still tap a card or approve a wallet transaction. A merchant can still see the normal payment flows. The real change happens at settlement: when the money actually lands, how fast it moves, whether it can move on weekends, and which intermediary controls the layer of trust around that transfer.
Stablecoins are the real prize because settlement is the real battlefield
Recent reporting from Mastercard itself points in that direction. In 2025, the company enabled stablecoins including USDC, PYUSD, USDG and FIUSD on its network. It also announced end-to-end capabilities for stablecoin transactions, from wallets to cash registers, in a release focused on the movement of value through the payments chain rather than crypto as an investment story.
That push included enabling wallets, merchant acceptance, and settlement functionality. Taken together, these materials indicate a company is trying to make the movement of the digital dollar useful within the network, not just off it.
The short-term usage scenarios follow from that design. Transfers are one thing. Cross-border payouts are another. B2B transfers, supplier payments, cash movements and merchant settlements all fit into the model. These are areas where 24/7 transfer capabilities, faster finality, and programmable terms can have practical value, even before consumers see a major change at checkout.
Tokenized deposits become relevant for the same reason. They are bank deposits issued in blockchain form, making them easier to route through programmable systems while remaining tied to regulated institutions.
A crypto exchange can help distribute or interact with digital assets. A custodian can hold them. A compliance vendor can screen counterparties and transactions. A banking partner can issue the money or support the fiat leg. A processor or network layer can move instructions and place them in the existing trading universe. Mastercard appears to want a seat at that intersection, where blockchain-native assets meet the familiar controls, rules and acceptance footprint of traditional payments.
Visa’s recent actions are in line. In late 2025, Visa announced a US stablecoin settlement in a release aimed at integrating the settlement. That suggests both major card networks have come to a similar conclusion: stablecoins are becoming credible rails for back-end money movement. Neither network seems willing to leave that area open to banks, fintechs or crypto infrastructure companies.
Still, the chance is real, but not yet completely mainstream.
The strongest reporting measure in this article is separating gross on-chain volume from actual payment usage. A McKinsey review, citing data from Artemis, estimated “actual stablecoin payments” at around $390 billion annually. That’s a meaningful base, but it’s much smaller than the most inflated values of raw stablecoin transfer volume.
So stable coins have not replaced card networks in commerce. Instead, they have become so important in settlement and money movement that card networks are now building up to contain the threat and reap the benefits.
DefiLlama estimated the total stablecoin market capitalization at approximately $309.0 billion. BVNK reported that 77% of crypto users surveyed would open a stablecoin wallet if their bank or fintech offered one, while 28% would convert or spend stablecoins within days. And a16z’s stablecoin estimate of $46 trillion in transaction volume last year should be treated as leading evidence of dollar movement on-chain, rather than as a pure payments number.
Taken together, these numbers paint a clear picture: the market is already big enough to matter, but it’s still early enough that control of the rails is still up for grabs.
If major retailers, large fintech stacks, processors, or banking consortia can move more value through stablecoin or tokenized-money systems, they can ultimately reduce dependence on the traditional card settlement economy. Reporting from the Journal on Walmart and Amazon examining stablecoins captured the direction of travel. Mastercard’s affiliate program can be read as a defensive response to that possibility. There is no panic or turning. It’s network defense.
The following proof points are simple.
- Look out for more issuer settlement announcements, merchant settlement implementations, bank stablecoin launches, tokenized deposit pilots, and case studies related to Mastercard’s Multi-Token Network.
- Look for processors and acquirers to move recurring production settlement flows to these rails. Pay particular attention to the published volume.
That’s where we’ll see things harden into a measurable shift in payments infrastructure, or fade back into branding.
For now, Mastercard’s crypto affiliate program looks less like a broad endorsement of crypto and more like an attempt to shape where digital dollars go.
The company has published the ecosystem map. The more difficult question is whether the next wave of stablecoin settlements will continue to use Mastercard’s network layers, or whether parts of the market will decide they no longer need them.
