TL;DR: Pay with USDC in 4 steps: create a wallet, buy USDC, scan the QR code at checkout, receive the PDF instantly.

Step 1: Create a wallet

Choose a wallet that supports USDC on the Polygon or Ethereum network.

Recommended wallets:

  • MetaMask (browser extension + mobile)
  • Trust Wallet (mobile)
  • Coinbase Wallet (mobile + web)

Download the wallet, follow the setup, and save your recovery phrase securely — never share it.

Step 2: Buy USDC

Buy USDC through the wallet or an exchange:

  • Exchange: Binance, Coinbase, Kraken
  • On-ramp: MoonPay, Ramp, Banxa (via your wallet)

Send USDC to your wallet address.

Step 3: Scan the QR code at checkout

At the checkout, choose USDC as your payment method.

Scan the QR code with your wallet app, or copy the address.

Enter the exact amount displayed on the checkout page.

Important: Use the correct network (Polygon or Ethereum) as shown on the checkout.

Step 4: Receive the PDF instantly

Once the transaction is confirmed on the blockchain (usually within minutes), your PDF delivery email is sent automatically.

The email contains a secure download link valid for 7 days and limited to 5 downloads.

Still unsure?

Card payment will be added when the processor approval is complete. Until then, the bankless road is open.

May your money move as freely as your feet.
