Not in the US, or no PayPal? Use the card guide

US PayPal accounts only. PayPal lists transfers to outside wallets for the US only. Open the PayPal app and look under Finances: if you do not see a crypto section with Buy and Send, use the card guide instead.

Buy PYUSD in PayPal

In the PayPal app go to Finances, tap Buy, choose PayPal USD and pay from your PayPal balance or a debit card. Buy your order total, plus a few dollars for the network fee.

1 PYUSD is 1 US dollar. PayPal says there is no fee to buy it.

More details
  • No credit cards: PayPal does not accept them for crypto. Use your balance or a debit card.
  • Paid by debit card, you can send it straight away. Paid by bank transfer, it can take several days to clear first.
  • The smallest amount PayPal sends on Ethereum is 10 PYUSD, and the weekly limit is $25,000.
  • You can start with as little as $1. Fees, limits and screens are set by PayPal. We are not affiliated with PayPal, and this is not financial advice.

Place your order, tap PYUSD

At checkout choose Pay with crypto and place your order. On our payment page tap PYUSD (the first one in the list) and keep the network on Ethereum. It shows the exact amount (20% off already included) and a deposit address.

The page address must be pay.qscpeptidology.com.

More details
  • Our page also shows Solana for PYUSD. Stay on Ethereum, which is the network this guide is written for.
  • The drawing is simplified; the real page may look a little different.

Send it from PayPal

In PayPal go to Finances, tap your crypto balance, then Transfer and Send. Paste our address (or scan the QR code), tap Got it on the network screen, type the exact PYUSD amount, tap Next, check the fee and tap Send Now.

Before you press Send Now

  • The network is Ethereum, the same as on our page (not Arbitrum).
  • You typed the amount in PYUSD, not in dollars.
  • The address matches the one on pay.qscpeptidology.com.

Anything different? Stop and contact us.

More details
  • PayPal works out a dollar amount only roughly, so type the exact PYUSD amount from our page.
  • The network fee is shown before you confirm. If it comes out of the amount you send, go back and send a little more, so that the full amount arrives.
  • PayPal cannot cancel or reverse a crypto transfer. Sending to the wrong network or address loses the money.
  • Send greyed out? Crypto transfers may be off on your account, a bank purchase may still be clearing, or your balance may be negative. PayPal support can tell you which.

Common questions

Can I use this outside the US?

+

Not at the moment. PayPal lists sending crypto to outside wallets for US accounts only. If you are somewhere else, use our card guide: buy USDC at an exchange app and send it to us.

Is there a fee?

+

PayPal says there is no fee to buy or send PayPal USD, but it charges a network fee when you send to an outside address. PayPal shows that fee before you confirm. Your bank may charge its own fees if you pay with a linked bank account or debit card.

Can I pay for the PYUSD with a credit card?

+

No. PayPal does not accept credit cards, or PayPal Credit, for buying crypto. Use your PayPal balance or a debit card. A purchase made by bank transfer can take several days to clear before you can send it.

I sent the wrong amount or used the wrong network. What now?

+

Crypto transfers cannot be cancelled or reversed. If the amount was short, send the difference to the same address. If you used a different network from the one on our payment page, contact us right away with your order number and the transaction ID. We will do what we can, but funds sent on a network we do not use may not be recoverable.
