Payment options for china peptide orders, including the methods we accept and why.
Standard methods are PYUSD on Solana, USDC on Solana, and USDT on TRC-20 (TRON).
Phantom Wallet — recommended for beginners
Phantom is our most user-friendly option for USDC on Solana. Use a suitable purchase provider when available, or receive USDC from a compatible service. Send the exact order payment to the order-specific address on your Peptides of China page. Phantom is not a USDT / TRC-20 wallet.
Buy crypto with a debit card through Mercuryo
Expand the detailed debit-card guide
Mercuryo is an external cryptocurrency purchase service. For card purchases, use a debit card. You pay Mercuryo using an available payment method and receive cryptocurrency at the address you specify. Peptides of China receives cryptocurrency, not a direct card payment.
Recommended: PayPal debit card
Use a debit card — not a credit card.
Peptides of China recommends a PayPal debit card for this crypto on-ramp.
Availability and payment approval depend on your region, card issuer and Mercuryo. This recommendation is not a guarantee of approval.
Currencies, payment methods, fees, limits, and verification requirements depend on your country and Mercuryo’s current offering. Mercuryo lists a Texas restriction for USDC. This Peptides of China card route uses USDC on Solana only. Confirm this exact pair in the widget before purchasing; if it is unavailable, do not substitute another asset or network. This guide covers the purchase Widget, not Mercuryo Wallet. USDT, PYUSD and native coins are not included in this Peptides of China card route.
The illustrated route: USDC on Solana
USDC → SOLANA
Select both USDC and SOLANA. SOL is a different cryptocurrency. Do not choose USDC on Ethereum, Base, Polygon, or another network. These illustrations apply only when your order’s current payment uses USDC on Solana.
Before you start: prepare for identity verification (KYC)
Mercuryo uses identity verification (Know Your Customer, or KYC). Be ready to complete the checks it requests before your purchase can proceed; requirements depend on your country and transaction.
- Valid government-issued ID Have the original document accepted for your country ready: a passport, national ID card, or driving licence where supported. Mercuryo’s current guide requires at least three months before expiry. US users must use a valid US driver’s licence or state-issued ID, not a US passport.
- Camera and a well-lit space Use a phone or computer with a working camera for document photos and a selfie/liveness check when prompted. Allow camera access. Keep all document corners visible and your face unobstructed; do not use edited photos or filters.
- Personal details and email access Have your full legal name, date of birth, and any address or additional details Mercuryo requests ready. They must match your ID. Keep access to your email for the verification code. US users should also be ready to provide their SSN to Mercuryo during its verification.
- Debit card and bank authentication Use a debit card. Keep the card details and access to your bank’s app or other authentication method ready for any payment confirmation it requests. Check that your balance covers the card charge, including Mercuryo’s fees.
Provide ID, selfies, card details, and other sensitive verification information only through Mercuryo’s official flow or its verification provider reached from that flow. Do not send them to Peptides of China. The demo below does not submit a purchase, card details, or KYC.
Real Mercuryo interface captures and the actual Peptides of China payment page rendered with demonstration data. The side-by-side examples show copying from Peptides of China and pasting into Mercuryo. The 350.00 USDC and illustrated wallet address are examples only: use your own order’s current amount and address. No purchase or personal data was submitted. The interface, fees, and availability may change.
- Open the payment details for your Peptides of China order
Use the payment currently due, not the full order total
For a deposit, copy USDC advance to buy from the Mercuryo order page, not the ordinary $10 deposit. Example: buy 25 USDC, cover a $10 unpaid deposit, and apply the remaining 15 USDC to the final balance. For final payment, use the exact remaining balance; do not add another deposit advance.
Open your individual order page using the order link provided after you submitted your request. Find the payment section for the payment currently due: the processing deposit or the remaining balance.
Check the required cryptocurrency, network, exact amount, and receiving address. Use the details currently shown for this order; do not reuse another order’s address or an earlier payment amount.
Choosing Mercuryo fixes the route to USDC · Solana and prepares your individual order wallet. Read this guide, then press Show my payment details. For a deposit, the card route uses an advance of at least 25 USDC: the unpaid deposit is covered first, and the rest reduces your final balance. The standard crypto deposit is unchanged. Only the amount and address have Copy buttons. Use your own order details, not the demonstration values.
Your Peptides of China payment form: one fixed asset/network pair, the current amount due, and the full address. Copy only the amount and address.
After reading the guide, reveal your payment details and use the Copy buttons. The illustration uses demonstration data, not your order amount. View animation (new tab)
- Open Mercuryo and select USDC on Solana
USDC → SOLANA
Choose the highlighted USDC row labelled SOLANA. USDC on a different network will not match a USDC / Solana order.
Open Mercuryo in a separate tab and keep your Peptides of China payment page open beside it. Mercuryo may initially select BTC; replace it with the pair required by your order.
Open the cryptocurrency selector beside You get and choose the USDC entry labelled SOLANA. Mercuryo lists the same cryptocurrency separately for different networks. This Peptides of China card route uses USDC on Solana only.
USDC is not SOL. Do not select USDC on Ethereum, Base, Polygon, or another network, or substitute USDT or another cryptocurrency. If USDC on Solana is not offered, stop and use another supported payment method.
USDC example: select the row explicitly labelled SOLANA. A matching ticker alone is not enough.
Open the selector beside You get, search for USDC, and select the SOLANA row. This is one selection step; the network is not copied or pasted. View animation (new tab)
- Enter your order amount
Peptides of China amount due → Mercuryo You get
Example: Remaining balance 350.00 USDC → You get 350 USDC on SOLANA. You pay is a different field and includes the card charge. Always use your own order’s current payment amount.
After reading the guide, show your order payment details. For a deposit, press Copy beside USDC advance to buy; for final payment, copy Current amount due. In Mercuryo, replace the amount in You get with this value. The illustration’s 350.00 USDC is only an example. For a $10 unpaid deposit, the card-route page instead shows a 25 USDC advance, including 15 USDC toward the final invoice.
You get is the quantity of cryptocurrency for the receiving address. You pay is the fiat amount charged to your debit card; it is calculated separately with Mercuryo’s fees. Do not enter 350 into You pay and assume that 350 USDC will arrive.
Send the purchase directly to your individual order wallet on USDC Solana. For deposits, use the advance shown on the Mercuryo order page. Peptides of China credits all USDC actually received: the unpaid deposit is covered and the additional funds reduce the final balance. The card charge and provider fees are not credited.
Wait for the quote to refresh, then expand the order summary and compare You get and the final cryptocurrency received with the exact amount due on Peptides of China. Review the rate, fees, and total card charge. If fees reduce the amount received, adjust the purchase before continuing.
The 25 USDC deposit advance is Peptides of China’s card-route amount, not a guarantee of Mercuryo’s minimum in every region. Check the quote before purchasing. If Mercuryo cannot quote the amount shown, use another supported method. For a final balance below 25 USDC, use the standard crypto method instead of overpaying the final invoice.
Peptides of China on the left: Copy your current amount due. Mercuryo on the right: replace the amount in You get with that value. 350 is an example, not the amount of your order.
Follow Copy on Peptides of China, then paste into You get on Mercuryo. The two screens stay visible together on larger displays and stack on phones. Use your own amount; 350 is demonstration data. View animation (new tab)
- Copy and paste the full receiving address
Click Buy to open Enter wallet address. Receive the cryptocurrency directly in the individual wallet assigned to your order. Use the current order address shown on your Peptides of China payment page.
Paste the complete receiving address into Mercuryo’s wallet-address field. Check the first and last characters against the source, and confirm the asset and network again. An order number, transaction hash, or order-page link is not a wallet address.
Read Mercuryo’s address-ownership notice and follow its verification requirements. Continue only after checking the destination. Enter your email, confirm the verification code, and complete any identity or payment checks Mercuryo requests. For card payment, use a debit card and review the payment details before confirming the purchase.
Directly to your individual order wallet
Peptides of China creates an individual receiving wallet for your order. Open that order’s payment section for the current deposit or remaining balance. Check the cryptocurrency and network displayed there, then press Copy address beside the wallet address or QR code.
Paste this full address into Mercuryo as the receiving address. It is the address from your order’s payment block, not your personal wallet address, an address from another order, the order number, or the order-page URL.
Compare the first and last characters with the Peptides of China page. Make sure Mercuryo’s selected asset and network match the order and that You get matches the exact amount currently due. If the order does not yet show a receiving address, wait or contact support before purchasing.
For the direct order-wallet route: Copy the full address on your Peptides of China page, then paste it into Mercuryo. The illustrated address is demonstration data, not an address to pay.
The animation demonstrates the direct order-wallet route using a sample address. Compare the first and last characters on both screens. Use your own order address, not this example. No purchase is submitted. View animation (new tab)
- Wait for delivery and return to your order
Wait for Mercuryo to send the cryptocurrency directly to your order’s individual wallet; do not make a second transfer for the same payment.
Return to your Peptides of China order page and follow the payment-check instructions shown there. A Mercuryo purchase confirmation does not by itself mean the blockchain transfer has arrived or that your Peptides of China order has been marked paid.

PYUSD via PayPal or Venmo
For eligible users, PayPal and Venmo may be sources or senders of PYUSD. They are not Peptides of China checkout processors. Use the provider’s external-transfer feature to send PYUSD on-chain to the order-specific PYUSD/Solana address displayed on your order page.
- Copy the PYUSD address and exact amount from the order page.
- In PayPal or Venmo, choose PYUSD external transfer.
- Paste the address and explicitly select Solana.
- Review the amount, address, network, and any fee before confirming.
Other standard methods
Send USDC only on Solana, or USDT only on TRC-20 (TRON), to the address shown for your order. For SOL on Solana, first select SOL on your order to get its unique wallet and a 60-minute quote including +5%.
Important transfer reminders
Availability can vary by region, account, and provider feature. Identity verification, transfer limits, and network fees may apply. Phantom is a compatible self-custody Solana wallet, not a guaranteed PYUSD on-ramp. Crypto transfers are irreversible: a wrong asset, network, address, or amount can result in permanent loss. ETH, BTC, and other unlisted assets remain support-approved alternatives. Do not send SOL against a USDC payment instruction.
