$USDC Coinbase officially launched Coinbase Payments on June 18, a three-layer platform that enables commerce providers to add USDC checkout without running their blockchain infrastructure.

The stack begins with Stablecoin Checkout, a wallet-native interface that supports hundreds of wallets, delivers gas-free transactions, and records payments in USDC.

Beneath it, an E-commerce Engine exposes application programming interfaces for authorization, capture, refunds, ledgering, and subscriptions, allowing payment service providers to integrate stablecoin flows into existing merchant dashboards.

At the base, the Commerce Payments Protocol executes smart contract escrow and settlement on Base, Coinbase’s layer-2 network, in sub-second blocks.

The company stated that the modular design eliminates the need for “crypto-native teams” and can settle global transactions at a lower cost than traditional card networks.
