Coinbase and Samsung Partner to Make USDC the Default Stablecoin for Samsung Wallet

Coinbase is integrating USDC as the default dollar stablecoin within Samsung Wallet, leveraging its institutional custody infrastructure to reach millions of Galaxy users. This move, launching in late October 2026, marks a significant step in embedding regulated digital assets into mainstream mobile hardware, providing a bridge between traditional finance and the on-chain economy.

What was announced

Starting the last week of October 2026, Samsung Wallet users in the U.S. market will see USDC automatically as their default dollar stablecoin when topping up balances. This integration is powered by Coinbase in collaboration with Bastion, a licensed stablecoin custodian and infrastructure provider overseen by U.S. financial regulators. The technical framework relies on Coinbase Prime, the firm’s flagship institutional platform, to provide subcustody for the USDC held within the wallet through its NYDFS-qualified custody services.

The partnership builds on a series of integrations between the two firms designed to lower the barrier to entry for digital asset adoption. In July, Samsung Pay was added as a payment option within the Coinbase app, and in October, Coinbase One benefits were extended to over 82 million Galaxy users in the United States. This latest update moves the relationship from simple payment connectivity to native asset management within the Samsung ecosystem.

The move comes amid significant growth for USDC, which is designed to be redeemable 1:1 for U.S. dollars and backed by cash and short-dated U.S. Treasuries. In 2025, USDC circulation grew by 72% to exceed $75 billion, while the number of wallets holding the asset increased by 59% to nearly 7 million. By making USDC the default option in a major mobile wallet, the companies aim to streamline cross-border money movement and 24/7 financial participation for a broad consumer base.

The companies involved

Coinbase is a central pillar of the global cryptocurrency market, operating as a publicly traded exchange and a major provider of institutional infrastructure. Beyond its retail trading platform, the company has increasingly focused on its institutional suite, Coinbase Prime, which offers custody, trading, and financing services to professional investors and corporate partners. Its role as a subcustodian in this partnership highlights its pivot toward becoming a foundational layer for broader fintech applications, moving beyond its origins as a simple brokerage.

Samsung is a global leader in consumer electronics and mobile hardware. Its Samsung Wallet serves as an all-in-one digital hub for payments, identification, and digital keys, competing directly with other major mobile wallet ecosystems. By integrating blockchain-based assets directly into its native wallet software, Samsung is positioning its Galaxy devices as secure gateways for the digital economy. The company maintains a significant footprint in the enterprise and consumer sectors, and this collaboration allows Samsung to leverage regulated crypto infrastructure without managing the underlying blockchain complexities directly.

What FF News has reported before

FF News has closely followed Coinbase’s aggressive expansion into the global payments and banking sectors. Recently, the firm announced a partnership with Thunes to bridge fiat and stablecoin global payments, aimed at streamlining international transfers. This followed a collaboration with Marqeta to launch stablecoin-backed cards, allowing users to spend digital assets at traditional merchant terminals.

Furthermore, Coinbase has been active in regional expansions, working with Gennius to launch regulated digital dollar services for banks across Latin America. These moves, alongside institutional developments like Marex’s launch of institutional QIS indices on digital assets, suggest a broader trend of crypto infrastructure being woven into the fabric of traditional financial services.

What this means

This announcement signals a shift in the stablecoin sector, moving from exchange-based liquidity to hardware-level distribution. By becoming the default dollar stablecoin on millions of Samsung devices, USDC gains a massive distribution advantage over competitors in the U.S. market. It puts pressure on other mobile wallet providers to clarify their own digital asset strategies or risk losing users to more crypto-native hardware ecosystems. The reliance on a regulated subcustody model also highlights that the future of mainstream crypto adoption likely rests on "invisible" infrastructure, where the user experiences the benefits of blockchain speed and 24/7 settlement without needing to navigate the complexities of private keys.
