# Common questions

Short, straight answers to what merchants ask most before going live.

## Your customers

**Do my customers need crypto, or a wallet, to take part?**
No. They create a free Frak wallet in about 10 seconds with Face ID or a fingerprint, no crypto knowledge, no jargon, no money up front. See [what your customers see](/guides/customer-journey/).

**Is this really my customers, or strangers?**
It's your real customers and the friends they personally invite. That's warm, trusted word-of-mouth, not cold ads.

**Can customers actually cash out their rewards?**
Yes. They can transfer their earnings to their bank account from the wallet whenever they like.

## Costs and payments

**How much does Frak cost?**
Frak takes a **20% commission** on your campaign budget. The other 80% goes to your customers as rewards. You only pay on real, confirmed sales.

**When are rewards actually paid?**
Only when a sale is confirmed. Until then the reward is held as "awaiting validation", so nothing leaves your budget for an order that isn't final.

**What happens if an order is refunded?**
The matching reward is cancelled automatically. You never pay for a sale that didn't stick.

**Can I control my spending?**
Yes. Set a budget cap (overall, or daily, weekly, monthly), pause a campaign any time, or switch reward payouts off entirely. [Add funds](/guides/dashboard/configure/funds/).

**Which currencies can I use?**
EUR, USD, or GBP via Monerium, or USDC via Circle. Most merchants keep the default (EURe).

## Setup and privacy

**Do I need to write code?**
Not for Shopify, WordPress, or PrestaShop, they all have ready-made apps. A fully custom site needs a little setup. [Pick your platform](/guides/).

**How long does setup take?**
About 5 minutes for most stores: install, connect, fund, and launch.

**Is my customers' data safe?**
Yes. A customer's email is only ever used to recover their wallet, never for unsolicited messages.
**Tip:** Still stuck? Every platform guide has its own troubleshooting section, and the [glossary](/guides/glossary/) explains any unfamiliar terms.
