Coinbase Partners with Samsung, USDC Becomes the Default Stablecoin on Samsung Wallet

On October 8, Coinbase's official blog announced that Coinbase will provide stablecoin services for Samsung Wallet, with USDC set to launch as the default USD stablecoin in the U.S. market during the last week of October 2026. When users top up their stablecoin balances, USDC will automatically display as the default option, and related assets will be held by Coinbase Prime Vault through NYDFS-compliant custody services, operated in partnership with licensed stablecoin infrastructure provider Bastion. Currently, USDC circulation has grown 72% in 2025 to over $75 billion, and the number of holding wallets has increased 59% to nearly 7 million.
