Coinbase is moving deeper into financial infrastructure with a new Samsung partnership that puts Coinbase Prime custody behind the USDC balance inside Samsung Wallet, giving the crypto exchange an institutional role in a mainstream consumer product without requiring users to begin inside Coinbase itself.
Starting in the final week of October, eligible U.S. Galaxy users will be able to access stablecoins directly through Samsung Wallet. USDC will be the first supported stablecoin and will automatically appear as the default dollar-denominated option when users top up their stablecoin balance.
Coinbase said the USDC held through Samsung Wallet will be custodied through Coinbase Prime using its New York Department of Financial Services-qualified custody infrastructure. The underlying framework will operate alongside Bastion, a licensed stablecoin infrastructure and custody provider.
The Coinbase announcement turns what had previously been a distribution relationship with Samsung into something structurally more important: Coinbase is becoming part of the financial plumbing underneath Samsung Wallet.
Galaxy Users Will Not Need to Start With the Coinbase Exchange
The distinction matters because the customer experience is centered on Samsung rather than Coinbase.
Samsung says eligible users will be able to send USDC to compatible wallets and transfer value to eligible bank accounts in more than 60 countries, where recipients may receive local currency. Users do not need to manage private keys themselves.
From the consumer’s perspective, the stablecoin sits inside the same Samsung Wallet already used for cards, digital keys and other services. Coinbase can remain largely invisible even though its infrastructure is safeguarding the underlying USDC.
That is a different model from convincing millions of Samsung customers to download a crypto exchange, complete a separate onboarding flow and actively become Coinbase users.
Instead, Coinbase is moving one layer down the stack.
Samsung owns the consumer interface and distribution. USDC provides the digital dollar. Coinbase Prime provides custody. Bastion helps supply the regulated stablecoin infrastructure, while blockchain partners including Solana and Sui are involved in network support.
The result is closer to embedded finance than a conventional crypto partnership.
Coinbase Prime Is Moving From Institutions Into a Mass-Market Wallet
Coinbase Prime has historically been positioned around institutional clients requiring custody, trading and financing infrastructure.
Putting that custody stack underneath Samsung Wallet expands the role considerably.
The end customer may be an ordinary Galaxy owner holding or transferring a modest amount of USDC, but the assets behind that interface are being held through the same Coinbase institutional platform used to service professional and enterprise customers.
This reflects a wider change in stablecoin adoption. Crypto infrastructure increasingly does not need to appear as a standalone crypto product.
Dave Finances recently examined the same transition when Telcoin embedded on-chain dollars directly into regulated banking and wallet infrastructure. The important shift was not simply another stablecoin balance. It was stablecoin technology disappearing underneath a familiar financial interface.
Samsung takes that concept to a much larger consumer distribution channel.
The Existing Samsung Relationship Already Reaches More Than 82 Million U.S. Galaxy Users
Coinbase and Samsung are not starting from zero.
Coinbase previously added Samsung Pay as a payment option in its own app before expanding the relationship to provide Coinbase One benefits directly through Samsung Wallet.
Coinbase says that broader partnership covers more than 82 million Galaxy users in the United States.
That figure should not be interpreted as 82 million immediate stablecoin users. The new functionality will initially be available only to eligible devices and customers, and actual adoption will depend on how many users choose to fund or transfer USDC.
But distribution matters.
Crypto companies have historically spent heavily acquiring customers and persuading them to install specialist applications. Samsung already controls a wallet surface on tens of millions of phones.
Coinbase can therefore gain exposure to stablecoin transaction flows without owning the front-end customer relationship.
USDC Becomes the Default Rather Than One Token Among Many
The default setting is another significant detail.
When a Samsung Wallet customer chooses to fund the new stablecoin balance, USDC will appear automatically as the default U.S. dollar stablecoin.
Defaults are powerful distribution tools because they remove an active selection step.
The user is not first being presented with a catalogue of dollar tokens and asked to compare reserve structures, issuers or liquidity. Samsung Wallet establishes USDC as the starting point.
That gives Circle’s stablecoin a direct path into consumer mobile-finance infrastructure while giving Coinbase custody and infrastructure exposure to any resulting balances.
Coinbase said USDC circulation increased 72% during 2025 to more than $75 billion, while the number of wallets holding the asset increased 59% to almost 7 million.
The Samsung rollout potentially adds another type of holder: someone who may think primarily in terms of sending digital dollars rather than trading crypto.
Cross-Border Transfers Could Be More Important Than Crypto Trading
Samsung’s announcement emphasizes money movement rather than speculation.
Eligible U.S. users will initially be able to transfer USDC to compatible wallets and send funds toward bank accounts in more than 60 countries. Depending on the destination, bank recipients may receive local currency rather than stablecoins.
That puts the product directly into the remittance and cross-border payments market.
It also resembles the broader infrastructure shift behind SBI’s investment in stablecoin payments provider dtcpay, where the strategic value lies in using stablecoins as settlement rails while allowing businesses and end users to interact through familiar payment products.
Samsung has already pointed toward a further expansion. Future versions could allow eligible users to spend stablecoins online or tap a Galaxy device at physical merchants.
Those features are not part of the initial U.S. launch, so they should not be treated as existing capabilities. But they show the potential direction: USDC moving from a wallet balance to a general-purpose payment asset inside Samsung’s consumer ecosystem.
Coinbase Is Becoming an Infrastructure Company Behind Other Brands
This is the more important development for Coinbase shareholders.
The company’s most recognizable business remains the Coinbase exchange, where customers buy, sell and trade crypto directly.
But Coinbase has increasingly been building services that can sit behind somebody else’s product: custody, wallets, stablecoin payments, developer infrastructure and crypto-as-a-service.
That can change the economics of the company.
An exchange depends heavily on customers choosing Coinbase as their trading venue. An infrastructure provider can generate business even when another company owns the app, brand and customer relationship.
The strategy resembles what payment processors achieved in traditional fintech. Consumers often know the wallet, merchant or banking app they are using without knowing which infrastructure company is processing the transaction behind it.
For Coinbase, becoming less visible could therefore be strategically valuable.
The Custodial Structure Also Changes the User Experience
The Samsung model is notably different from the self-custodial architecture favored by many crypto-native wallets.
Samsung says customers will not need to manage private keys themselves. Coinbase Prime’s custody infrastructure instead sits behind the balance.
That sacrifices part of the self-custody model in exchange for a more conventional consumer experience.
Most mainstream users are accustomed to opening an app, seeing a dollar balance and expecting the provider to handle security and recovery. Asking those same users to protect seed phrases can create a major adoption barrier.
The Samsung-Coinbase design removes much of that friction.
It also concentrates custody risk in regulated intermediaries, making operational controls, asset segregation and the legal structure behind customer balances more important than they would be in a self-custodial wallet.
That contrast is particularly interesting beside self-custodial stablecoin banking models, where the user retains direct blockchain control.
Coinbase’s Biggest Stablecoin Opportunity May Be Outside Coinbase
The Samsung deal ultimately illustrates where stablecoin adoption may be heading.
The first generation of crypto adoption required users to consciously enter crypto: download an exchange, open an account, buy a token and learn new financial terminology.
The next generation may look much less like crypto.
A Galaxy user opens Samsung Wallet. They choose to add dollars. USDC appears automatically. Coinbase Prime handles custody in the background. Bastion and blockchain partners handle other pieces of the infrastructure. The user sends money abroad without necessarily thinking about the underlying stack.
That is considerably more powerful than another logo appearing inside the Coinbase app.
The immediate launch remains limited to eligible U.S. Galaxy users, and Samsung has not disclosed how many customers it expects to activate the stablecoin feature. Its tap-to-pay ambitions also remain future plans rather than launched products.
But the architecture is already clear.
Coinbase is no longer trying only to make Coinbase the place where consumers use crypto. It increasingly wants Coinbase infrastructure to power financial products wherever those consumers already are.
With Samsung Wallet, that means Coinbase Prime could be holding the digital dollars while Samsung owns the screen.
