Buy Robux with a crypto card

Roblox sells Robux in packs and through the Premium subscription. On the website the payment is a card charge at Roblox prices; in the mobile apps it goes through the app store, which sometimes costs more and always uses the store's payment methods. Crypto is not accepted on either.

A prepaid Mastercard in US dollars is accepted on roblox.com. Fund it with USDT, add it at checkout and buy the pack.

What Robux costs

Packs start around $4.99 and the price per Robux improves with larger packs; Premium is a monthly subscription that includes a Robux allowance. Roblox prices in the currency of your account country. In US dollars the card is charged the exact price plus the $0.10 service fee; in other currencies the Mastercard rate plus 2.5% applies.

Buying on the website

Open the Robux page on roblox.com, choose a pack, pick card as the payment method and enter the card details with the name from your CryptoCardex account and the billing address from sign up. Roblox may ask for a postal code. Buying on the website also avoids the app store route on your phone.

If a payment is declined

Roblox uses the billing address for fraud checks, so a mismatch between the address and the account country is a common cause. Second is balance: the pack price plus a small hold. Retry once after fixing the one that applies; repeated attempts can block the card at Roblox for a day.

What the card itself costs

The card costs $49.99 once and nothing per month. A top up is 3% plus the network fee. A purchase in a currency other than US dollars costs 2.5% of the amount, every approved purchase over $1 carries a $0.10 service fee, and the issuing bank's fee on a purchase is passed on at cost. All of it is in one table on the pricing page; if a charge is not there, we do not take it.

How to get the card and pay

1. Open the card. Sign up with an email address and pay $49.99 once for the virtual Mastercard. The card number, expiry date and CVV appear in your account about two minutes later. No passport and no selfie.
2. Top it up with crypto. Send USDT or USDC on TRON, BNB Chain, Polygon or Ethereum to the deposit address shown in the account. The top up costs 3% plus the network fee, and the balance is held in US dollars.
3. Pay at the checkout. Enter the card like any other Mastercard: number, expiry, CVV, the name from your account and the billing address it asks for. The merchant sees an ordinary card payment, not crypto.
