Phantom-Wallet Checkout — Häufig gestellte Fragen

Why does Phantom show clean transaction previews on XPayr checkouts?

XPayr constructs deterministic, single-purpose payment instructions verified against Phantom simulation rules so buyers see the exact USDC/USDT/SOL amount leaving their wallet before signing.

How fast do Phantom Solana-Zahlungen trigger my XPayr webhook?

Solana finality and XPayr RPC verification typically complete within 1–3 seconds, firing your HMAC-SHA256 payment.completed webhook immediately.

Can Phantom users also pay Base or Polygon USDC through XPayr?

Yes. Phantom announces both Solana Wallet Standard and EIP-6963 EVM providers, allowing seamless checkout across Solana, Base, Polygon, and Ethereum.
