Häufig gestellte Fragen — Wallets & Exchange QR
Can customers pay an XPayr invoice without MetaMask or a Web3 browser extension?
Yes! Every XPayr Dualer Checkout session includes both Web3 1-Click Pay (for MetaMask, Phantom, Rabby, Coinbase Wallet, Tonkeeper, TronLink, and 350+ WalletConnect apps) and Direkter Börsen-QR Mode — allowing Binance, Bybit, OKX, Kraken, and Coinbase exchange users to pay via standard QR withdrawal.
How does XPayr prevent stuck orders when Binance or Bybit deducts a withdrawal fee?
XPayr features configurable Underpayment Tolerance (default 1%, capped at $0.50 USD). When an exchange deducts a small $0.15–$0.30 network fee from the buyer withdrawal, XPayr automatically marks the order completed and dispatches a signed payment.underpaid_accepted webhook.
Does XPayr support hardware wallets and corporate Safe{Wallet} multisigs?
Yes. Ledger Live, Trezor, Keystone, and Safe{Wallet} corporate multisigs connect seamlessly via WalletConnect v2 (/wallets/walletconnect) or settle via Direct Address QR across 12 supported blockchains.
Does XPayr ever custody buyer or merchant wallet private keys?
Never. XPayr is 100% non-custodial infrastructure: Web3 1-Click Pay executes an atomic 99.5% / 0.5% smart-contract split straight to your wallet, and Direkter Börsen-QR routes 100% on-chain to your own address.
