Hardware Ledger y Bóveda Fría Empresarial Checkout — Preguntas frecuentes

Does my Ledger hardware wallet need to stay connected for my store to accept crypto?

Never. Receiving on-chain funds only requires your public deposit addresses. Your Ledger hardware device remains powered off in your physical safe while XPayr verifies blocks and notifies your backend via webhooks.

Can buyers also pay XPayr checkouts using their own Ledger device?

Yes — buyers connect Ledger Live via WalletConnect v2 (/wallets/walletconnect) or pair their Ledger with MetaMask, Rabby, Phantom, or TronLink for 1-click hardware-signed checkout.

What about Ledger Enterprise institutional vaults?

Ledger Enterprise multi-approver governance vaults work seamlessly as destination payout addresses across EVM, Bitcoin, Solana, and TRON.
