How payment works

New to paying with crypto? It takes about two minutes. You only need a wallet or exchange account holding USDT, Bitcoin or Ethereum.

Pay in crypto

Choose USDT, Bitcoin or Ethereum at checkout. Prices are in dollars and converted for you.

Confirmation is automatic

We watch the network for your payment. It usually confirms within five minutes — nothing to send us.

Download right away

Your private download link appears on screen and is emailed to you. It opens once, so save the file.

  1. 01

    Pick your title and enter your email

    On any product page, type the email where your download link should go, then choose the coin you want to pay with. No account is created.

  2. 02

    Copy the address and the exact amount

    The next screen shows our wallet address for that coin and the exact amount to send, locked to the dollar price at that moment. Copy both with one tap.

  3. 03

    Send it from your wallet or exchange

    Paste the address into your wallet or exchange withdrawal screen and send the amount shown. Send that amount or a little more — a smaller amount can't be accepted. For USDT, use the network named next to the address (TRC-20 or ERC-20).

  4. 04

    Tap “I've sent the payment”

    You get a transaction reference for your records and a five-minute countdown while the blockchain confirms. You can close the tab — the link is emailed either way.

  5. 05

    Your download unlocks by itself

    As soon as the coins arrive at our address, the page turns into a download button and the same link reaches your inbox.

  6. 06

    Save the file

    The link works once and stays valid for 24 hours. If anything goes wrong, reply to the email with your transaction reference and we'll re-issue it.

We never ask for a seed phrase, private key or card details — only a payment sent from your own wallet.
