Important – AIS Data Usage & Third-Party Streaming
MastNode is a purpose-built AIS + GNSS DePIN device designed primarily for operation within the MastChain network. It is not marketed as a general-purpose standalone AIS network receiver.
References to TCP/IP and UDP/IP in the specifications describe the device’s network communication capabilities and do not indicate user-configurable AIS data output or streaming.
MastNode does not provide, as a standard feature, AIS/NMEA/AIVDM output over TCP/UDP, a user-accessible AIS TCP/UDP server, or unrestricted forwarding of received AIS data to third-party servers or applications.
Any future external AIS data output or third-party streaming functionality is subject to MastChain firmware capabilities, network policies, and authorization.
Important – Returns After Onboarding
Once a MastNode is onboarded to the MastChain network, its integrated secure element is permanently and irreversibly paired to your operator account. The cryptographic chip cannot be re-provisioned or reset for another user, so an onboarded (activated) device cannot be restocked, resold or returned.
Pre-orders can be cancelled for a full refund at any time before the device ships. After delivery, the statutory 14-day right of withdrawal applies only to devices that have not been onboarded to the network. Your statutory warranty rights for defective products are not affected. See our Refund and Returns Policy.
