FAQ
Questions about top-ups.
How credits, payments, and promo codes work.
What's the difference between Stripe and FreeKassa?
Both charge the same price in USD. Stripe handles standard card payments. FreeKassa adds more methods — Russian cards (Mir, SBP) and crypto (USDT, BTC and others). Pick whichever suits you at checkout.
How fast do credits arrive?
Credits are added to your balance as soon as the payment confirms — usually within a few seconds.
Is it safe to pay?
Yes. Your card or wallet details never touch this site — Stripe and FreeKassa handle the payment pages, and every payment is verified server-side before credits are added.
What does an affiliate code do?
Applying a friend’s affiliate code gives you their discount on this order. Promo codes from giveaways are redeemed on the Redeem page instead.
