Checkout that can be tested
Start with payment links or an embedded widget, then move into API checkout when product or finance automation is ready.

XPayr compared with a manual wallet-only flow
| Need | Manual wallet address | XPayr |
|---|---|---|
| Payment confirmation | Manual chain checks or screenshots. | Payment session status, transaction logs, and webhooks. |
| Fee story | Often unclear across tools and manual processes. | Flat 0.5% XPayr gateway fee, before network gas or external route costs. |
| Supported routes | Depends on what the merchant manually monitors. | EVM routes, TRON USDT, Solana SOL/USDC/USDT, and published token availability. |
| Operational scaling | Difficult once invoices, users, or deposits grow. | Links, widgets, API/webhooks, recurring records, Payout Hub, and settlement policies. |

How much does XPayr charge?
