Popular ways to top up
These are the most used methods. Every one feeds the same credit balance, and checkout may offer more depending on your region.
Apple Pay & Google Pay
One-tap checkout on your phone or browser; your wallet stores the card details, not us.
PayPal
Check out with your PayPal balance or a linked card or bank, without entering card numbers on a new site.
Alipay 支付宝
Scan and confirm in the Alipay app. A familiar option if you are paying from mainland China.
USDT (TRC-20)
Send USDT over the TRC-20 network and your credits are added once the transfer confirms on-chain. Useful where cards are inconvenient.
