MastChain is an operator-run network that captures ship tracking data (AIS) straight from the air. Add coverage and earn $MAST for the data you collect.
Messages signed today · 0,000,000Put a receiver where the ships are: coasts and ports, straits and chokepoints, busy rivers and inland waterways, and anywhere commercial shipping runs. That is where coverage counts most.
Ships broadcast their position constantly over AIS. A MastNode listens for those signals straight from the air, so anywhere with a clear view of water works: a coast, a harbour, or an inland waterway. The more vessels that pass within range, the more traffic it pulls in.
Every message is cryptographically signed the instant it is received, right at the receiver that caught it. The signature makes each record tamper-evident and traceable to its source, so spoofed and impossible positions are caught before they ever count.
Operators earn $MAST for the coverage they hold, measured hex by hex. The network rewards most where reception is scarce, so a well-placed receiver on an empty stretch of coast is worth more than another in a crowded port.
Read the rewards guideThe MastNode is a purpose-built AIS receiver, assembled with our hardware partner MonsPro. Plug it in where the ships pass: coastal regions, inland waterways, ports and terminals, or anywhere with commercial shipping traffic. Give the antenna a clear line of sight to the water and it joins the network. Onboarding is seamless, with a simple setup process that needs no specialist knowledge.
Through our partnership with onocoy, a MastNode contributes to two networks at once. It strengthens MastChain's maritime coverage and onocoy's precise-positioning network from the same hardware, so the device is earning across both from the day it comes online.
One MastNode feeds both networks. No second device, no second install.
The device contributes from the moment it is online, while the maritime map is still filling in.

$MAST is the utility token of the network. Operators earn it for the hex coverage they verify, with rewards weighted toward the coasts, straits, and chokepoints where reception is most valuable. Each station also posts $MAST as a security bond, and $MAST is the fee required to transact on the MastChain network.
$MAST is a utility token for participating in the MastChain network. It is not an investment, security, or a promise of profit. Network rewards depend on factors including coverage, placement, uptime, and the emissions schedule, and can change. Nothing on this page is financial advice. Availability may be restricted in some jurisdictions.

On 1 March, we opened a Request for Comment (RFC) on Reward Mechanism 2.0: Performance & Seniority. Your feedback helped shape the updated reward model, scheduled to take effect on 25 September. It recognises reliable operators while encouraging new deployments that strengthen the network’s coverage.

Most DePIN networks build supply and hope demand follows. Maritime AIS data is different. The $2B+ buyer market has existed for decades
