Every Harbor deposit does two jobs.
Half the yield goes to you.
The other half funds Sea Verity, the network verifying the ocean in real time.
One deposit. Two products moving forward.

Ethra Ship is more than just a single product.
Here's how it all breaks down.
Ethra Invest has operated three dry bulk carriers since 2021, moving cargo and generating revenue years before either product below existed. Sea Verity and Harbor both sit on that operating history.
Sea Verity turns it into maritime intelligence: proof of presence, identity, and port activity, confidence-scored by a network of reporters, AI, and independent controller nodes rather than asserted outright. Tracking the type of signals that may be missed by legacy systems.
Harbor is your way to participate.Deposit USDC or USDT on Base into carefully selected Morpho vault strategies.
The eligible yield is then split 50/50:
50% goes to you.
50% goes directly toward building Sea Verity.
Your deposit earns yield while helping fund the next stage of Sea Verity.
One fleet, two products, moving forward together.
AIS anomalies are becoming an increasingly serious challenge for maritime operators.
In Q1 2026 alone, nearly 978,000 GPS jamming events were recorded globally, with 98% concentrated in the Middle East Gulf, affecting more than 1,100 vessels.
When GPS interference compromises AIS reliability, the signal may no longer tell the full story.
That’s the exact maritime environment Sea Verity’s pilot is built to address.
Before a vessel departs to sea, it must chart a path.
But charting a path and seeing the route ahead are two different things.
Your yield deserves the same kind of visibility.
No hidden currents. No obscuring fog.
That's what the next leg of Ethra's journey is built for.
Tomorrow, the map is revealed.
Nearly 80% of everything the world trades moves by sea.
Almost none of that activity has ever been something an everyday person could participate in.
The path towards open participation in Ethra's maritime network is being charted.

Most of it just floats. Capital adrift.
No anchor. No dock.
Every ship needs its harbor.
Capital is no different.
