How to pay with crypto
Four steps, written for people who have never done it. It is the fastest way to pay, with no ID check from us, and it saves you 10%.
Two checks before you send. The payment page address must be pay.qscpeptidology.com, and the network must be Ethereum (ERC-20). Anything else, stop and contact us.
1. Get some USDT or USDC
Buy it from a crypto exchange or app that works in your country (for example Coinbase, Kraken or Binance; we are not affiliated with any of them, and this is not financial advice). The exchange asks you to verify your identity once, and lets you pay by bank transfer or card. USDT and USDC are dollar-linked coins, so the amount does not move while you are sending it. Buy a little more than your order total to cover the exchange's withdrawal (network) fee.
2. Place your order and choose Pay with crypto or card
You land on our payment page at pay.qscpeptidology.com. Under "Pay with crypto" pick USDT or USDC (ETH, PYUSD and cbBTC are listed too). Every coin on this page is sent on the Ethereum network. The page shows the exact amount to send and a deposit address with a QR code. It also gives you 10% off.
3. Send the exact amount on the Ethereum network
In your exchange or wallet, choose Withdraw or Send, paste the deposit address, and select the network "Ethereum (ERC-20)". Enter the exact amount shown. If your exchange takes its fee out of the amount you enter, add that fee so the full amount still arrives. Check the address and network twice before you confirm: a transfer on the wrong network can be lost for good.
4. Wait for confirmation
The payment page watches the network and updates by itself, usually within a few minutes (longer when the network is busy). Once it confirms, you are brought back to our site with your order marked paid, and we pack and dispatch it right away. Keep the transaction ID (TxID) your exchange shows you, in case you need to contact us.
Prefer a card? See how paying by card works. Not comfortable with either? Place your order and use the link in your confirmation email to ask for a PayPal or Revolut payment link.
Common questions
I have never used crypto. Is this hard?
+
The first time takes longer because you set up an account with an exchange and verify your identity there. After that, paying is a copy, paste and send. If you would rather not, you can pay by card (one-time ID check) or ask for a PayPal or Revolut payment request at the regular price.
Do I need to verify my identity with QSC?
+
No. Paying from your own crypto wallet has no ID check on our side. Your exchange will ask for ID once when you open the account, which is the exchange's rule, not ours.
Which coin should I use?
+
USDT or USDC. They are dollar-linked, so the amount stays the same while you send. ETH and cbBTC prices move, so the amount shown can change if you wait.
I sent slightly less than the amount shown. What now?
+
The order stays unpaid until the full amount arrives. Send the missing amount to the same address, or contact us with your order number and the TxID and we will help.
I used the wrong network or the wrong coin.
+
Contact us right away with your order number and the TxID. We will do what we can, but funds sent on a network we do not use may not be recoverable. Our payment page uses the Ethereum network for every coin.
How long does it take?
+
Usually a few minutes after you send. When the Ethereum network is busy it can take longer. The payment page updates on its own.
Can I pay another way?
+
Yes. Card (with a one-time ID check) is on the same payment page under Card & wallets; see our step-by-step card guide. Or place the order and use the link in your confirmation email to request a PayPal or Revolut payment link. Those are charged at the regular price, without the 10% discount.
