Perguntas Frequentes — Switching From Stripe Pay with Crypto
Do we have to rip out Stripe for credit cards to use XPayr?
Not at all. Most SaaS and e-commerce teams keep Stripe for domestic credit cards and offer XPayr as the dedicated "Pay with Crypto (USDT / USDC)" button — capturing global buyers whose cards decline and saving 66% vs Stripe 1.5% crypto fee.
Can non-US SaaS companies in Europe, UK, APAC, or LATAM use XPayr?
Yes. Unlike US-restricted crypto rails, XPayr serves global merchants across 24+ priority corridors (/global-coverage) subject to standard Acceptable Use boundaries.
How do we handle SaaS subscription renewals without vaulted cards?
Use XPayr Cobrança Recorrente (/recurring-billing) smart renewal links and ES256 wallet-bound Kit de Licenças entitlements (/license-kit). Model your MRR uplift at /tools/subscription-churn-recovery-calculator.
