Update: the ManaBuy promo-code rollout for HoYoverse products is currently available for Genshin Impact top-ups only. Players using USD checkout can enter manaup before payment to receive 5% coupon savings on eligible Genshin Impact orders. Honkai: Star Rail and Zenless Zone Zero are not part of the current coupon availability yet, so users should not expect the code to apply to those products until ManaBuy announces a wider rollout.
Quick answer: Use promo code manaup for eligible Genshin Impact top-ups on ManaBuy when checkout is set to USD. Apply the code in the Promo Code field before payment, then confirm that the Promo Code Savings line appears in Payment Details before clicking Pay Now.
ManaBuy now shows a Promo Code field in the checkout flow for eligible Genshin Impact orders. Instead of changing the Genesis Crystal package itself, the coupon is applied after the user enters the code and clicks Apply. This keeps the order flow easy to review: select the Genshin Impact product, enter the correct UID and server, use USD checkout, apply manaup, and check the final total before paying.

The important limitation is product availability. The code should be treated as a Genshin Impact coupon for now, not a general HoYoverse coupon across every ManaBuy product. If a user is buying Honkai: Star Rail or Zenless Zone Zero, they should wait for a separate availability update instead of assuming the same code will work.
| Product | Main paid item on ManaBuy | Current coupon status | Checkout note |
|---|---|---|---|
| Genshin Impact Top-Up | Genesis Crystals and related eligible options | Available now for eligible USD checkout orders | Enter manaup, click Apply, and verify the Promo Code Savings line. |
Open the Genshin Impact Top-Up page on ManaBuy and choose the package you want.
Enter the required account information carefully, including UID and server, exactly as requested by the product page.
Use USD checkout. The current coupon rollout is temporarily USD-only, so the code may not apply in other currencies yet.
Enter manaup in the Promo Code field, click Apply, and check the final Payment Details before paying.

The USD-only rule is a temporary rollout limit, not a permanent statement about every future checkout currency. If users do not see the discount after entering the code on a Genshin Impact order, the first thing to check is the selected currency. They should also confirm that the order is on the Genshin Impact product page and that the code was applied before payment.
This checkout-first coupon design also makes the savings easier to audit. The Genshin Impact package remains the same, while the final payable amount changes only after the code is accepted. That means players can compare the Product Amount, payment fee, Promo Code Savings, and Total on one screen before deciding whether to continue.
Honkai: Star Rail and Zenless Zone Zero are not included in the current manaup availability. ManaBuy may expand coupon support later, but this article will stay focused on Genshin Impact until those products are confirmed. For now, users should not promote or expect the code as a working HSR or ZZZ discount.
If the rollout expands, ManaBuy can update this article again with the additional product pages, paid item names, and checkout notes. Until then, the safest public message is simple: manaup is currently for eligible Genshin Impact USD checkout orders only.
Coupon savings are useful only when the order details are correct. Before completing a Genshin Impact top-up, check the product, package, UID, server or region, payment method, coupon code status, and final USD total. ManaBuy checkout shows the discount before payment, so users can review the amount before deciding whether to continue.
Use this product page for Genesis Crystal top-ups and related eligible options.
Open Genshin Top-UpThe current code is manaup. Enter it in the Promo Code field at checkout before payment.
The coupon gives 5% savings on eligible Genshin Impact USD checkout orders. Always confirm the Promo Code Savings line before paying.
Not currently. The confirmed availability is Genshin Impact only. HSR and ZZZ should be treated as pending until a separate update confirms support.
Not right now. The current rollout is temporarily limited to USD checkout. Other currencies may not show the coupon savings yet.
Check that the code is spelled manaup, the product is Genshin Impact, and checkout is set to USD. If the savings line still does not appear, do not pay until you have reviewed the order.
