Samsung Wallet: USDC Transfers on Solana and Sui for U.S. Galaxy Devices

What Samsung Announced

Samsung Electronics America said on October 7 that Samsung Wallet will add stablecoin features in the last week of October for eligible Galaxy users in the United States. The first supported asset is USDC. At launch Samsung says the feature will be available on 82 million Galaxy devices in the U.S. that are compatible with Samsung Wallet. That is a device count from the release, not a user count.

Woncheol Chai, EVP and Head of the Digital Wallet Team at Samsung Electronics, describes the aim this way: sending money abroad should feel as familiar as the wallet already on the phone. Users should be able to start USDC transfers without installing another app or managing private keys themselves.

What Works at Launch

USDC to compatible wallets: eligible users can send USDC from Samsung Wallet to wallets or exchange accounts that accept USDC on a network Samsung Wallet supports. Samsung does not charge a fee for that. The recipient’s provider may. Speed depends on the network. Transfers to sanctioned jurisdictions are prohibited.
To bank accounts: users can also send funds to eligible bank accounts in more than 60 countries, paid out in local currency. The country list appears in the app. Fees apply, vary by country and amount, and are shown before confirmation. Not every bank or account type is supported.
Not at launch: paying with stablecoins in a store or online is described only as a possible later capability, not as part of the initial release.

Requirements in the footnote: eligible U.S. residents aged 18 or older, a Samsung account, identity verification, biometric authentication set up, a Galaxy device compatible with Samsung Wallet, and Android 13 or higher. Transfers require biometric approval on the registered device.

How stablecoins work on Solana is covered in Stablecoins on Solana.

Who Holds the Coins

This is not a self-custody model. Samsung’s footnote says accounts, custody, and money movement are provided by regulated partners, not by Samsung. Samsung is not a bank, money transmitter, or digital-asset custodian and does not hold customer funds.

Stablecoin accounts run on Bastion. Coinbase is the official sub-custodian and safeguards all USDC in Samsung Wallet via Coinbase Prime Vault. In the Samsung release, Bastion says it holds a New York trust charter (Bastion Platforms Trust Company, LLC) and preliminary conditional approval from the U.S. regulator OCC for a national trust bank charter. When users select “Buy Stablecoin,” USDC appears as the default dollar stablecoin.

Solana and Sui, Not Solana Alone

Samsung’s text says separate partners provide infrastructure and blockchain support, including Solana and Sui. Samsung does not describe this as an exclusive Solana partnership.

The Solana Foundation, in its own release, describes USDC transfers on Solana, integrated fiat on- and off-ramps, and also Samsung Pay. It mentions further markets only subject to local regulation. The Foundation also says stablecoin supply on Solana is up nearly 20 percent year over year and that the network has processed more than $5.25 trillion in stablecoin volume in 2026 — Foundation figures, not an audited statement.

Sui, in its own post, describes USDC transfers on Sui inside Samsung Wallet, initially in the U.S. as well, and says the SUI token itself is not supported in the wallet. Samsung’s release does not spell out which transfer uses which network. The partner list that governs is Samsung’s: Solana and Sui.

Not Available in the EU

For readers in Germany, Austria, and Switzerland, the service is not usable at launch. Samsung limits it to eligible U.S. residents. Samsung ties any expansion to regulation in each country; the Solana Foundation speaks of further markets only subject to local requirements. Neither release gives an EU timeline.

In the EU, the framework is the Markets in Crypto-Assets Regulation (MiCA, Regulation (EU) 2023/1114). Under Article 59, a person shall not provide crypto-asset services within the Union unless authorized as a crypto-asset service provider — or, for certain already supervised financial firms, via the route in Article 60. That is the rule in force, not an announcement by Samsung. Switzerland is outside MiCA; the service is still not offered there, because eligibility is limited to the United States.

What to Watch

Whether the feature appears on the stated devices in the last week of October, as announced
Whether Samsung later names further countries or follows through on in-store payments
