Samsung Wallet and Samsung Pay users in the United States will be able to send cross-border payments in USDC starting in the last week of October, with Solana providing the underlying blockchain infrastructure. The feature will initially reach 82 million U.S. Galaxy devices and will not require a separate crypto application. Integrated fiat on- and off-ramps will let users convert between local currency and stablecoins within Samsung's wallet experience. Samsung plans to expand the service to additional markets subject to local regulatory requirements. Woncheol Chai, EVP and Head of the Digital Wallet Team at Samsung Electronics' Mobile eXperience business, said the partnership is intended to make stablecoin transfers simpler for Galaxy users. The announcement revises the earlier account of Coinbase and Bastion as principal providers for the rollout by naming Solana as Samsung's infrastructure partner. Earlier plans also described wallet transfers, bank-account payouts, identity verification, biometric authentication, access to more than 60 countries and local-currency receipt for bank recipients. Solana's stablecoin supply has increased nearly 20% year over year, while the network processed more than $5.25 trillion in stablecoin volume during 2026. PayPal and Western Union already use Solana for stablecoin activity. Separately, the Solana Foundation joined the x402 Foundation as a founding member earlier in April, and the foundation and Google Cloud launched Pay.sh the following month to let AI agents pay for API services using Solana-based stablecoins. SOL was down around 3% over 24 hours and trading near $115 at the time of writing.
