The service is expected to launch in the last week of October 2026, with USDC as the default dollar stablecoin. Coinbase will provide subcustody through Coinbase Prime, alongside licensed infrastructure partner Bastion, Zacks reported.

Samsung’s broad consumer reach could help Coinbase introduce USDC to users beyond its existing crypto customer base. Integrating stablecoins into a familiar digital wallet could encourage adoption for payments and cross-border transfers, strengthening Coinbase’s position in the digital payments ecosystem.
The opportunity is supported by rising adoption. In the second quarter of 2026, average USDC balances held in Coinbase products reached a record $20 billion, up 44% year over year. More than 30% of circulating USDC was held in Coinbase products at quarter-end.
Wider adoption could create opportunities across custody, payments and other stablecoin-related services. It may also support activity on Base, Coinbase’s Layer-2 blockchain network, if users transact through services connected to the network.
However, greater adoption will not automatically translate into higher earnings. The financial impact will depend on customer activity, transaction volumes, operating costs and revenue-sharing arrangements. If the partnership generates sustained usage, it could broaden Coinbase’s distribution and support revenue diversification beyond trading fees.
