Accept crypto payments without turning XPayr into your wallet.
XPayr é construído como uma infraestrutura de pagamento sem custódia. Os comerciantes mantêm o controle da carteira enquanto o XPayr lida com sessões, registros de status, contexto de roteamento e webhooks.
Non-custodial settlement means XPayr does not hold merchant funds as an internal balance, store merchant private keys, pool merchant assets, or operate a withdrawal wallet. Payment behavior follows the configured wallet, network, token, and route settings.
