The recent @coinbase and Shopify partnership announcement means that millions of merchants will be able to seamlessly accept USDC payments on @base.

The integration used CDP Wallets’ Smart Wallet API and CDP Paymaster to enable a seamless, gasless payment flow tailored to Shopify’s operational and compliance needs—without adding friction.

CDP’s Smart Wallet infra provided:

→ Nonce management: fee sequencing via CDP’s Bundler
→ Built-in gas management: no need for custom relayers
→ Transaction simulation: failed operations are caught before submission
→ KYT enforcement: compliant with transaction screening requirements

Key integration components:

→ Operator Wallets: programmable transaction flows + buyer profile reuse
→ Custom Signing: our own signing keys, keeping full control of wallet operations
→ Gas Sponsorship: Paymaster covered gas fees on Base
→ Streamlined UX: wallet operations and gas handling fully abstracted

CDP Wallets' Smart Wallet API is used to create a new Smart Wallet for each Operator.

These wallets are ERC-4337 compatible and enable programmable transaction logic—without requiring end users to handle wallets, keys, or gas management directly.
