How Crypto USDC Checkout Works

June 1, 2026

Paying with USDC is straightforward, even if you are new to crypto. Here is the full process from start to finish.

First, at checkout you select Crypto USDC and choose a network. We support Base, Polygon, and Arbitrum — Base is the cheapest (around one cent in fees) and the one we recommend for most buyers.

Next, the payment page shows you a wallet address and an exact USDC amount. Open your wallet (MetaMask, Coinbase Wallet, Trust Wallet, and others all work), switch to the network you chose, and send exactly that amount to the address shown. Sending the exact amount matters — it is how we automatically match your payment to your order.

Important: send only USDC, and only on the network you selected. Sending a different token, or sending on a different network, can result in lost funds.

Once your payment lands, we confirm it and deliver your CDK code to your order email. Be sure to check both your inbox and your spam folder.
