Ethra is a protocol for digital participation in the global maritime industry, covering everything from ecosystem governance to regulated real-world asset exposure. Built by Ethra Invest, a team of seasoned dry bulk operators running an owned-and-operated fleet since 2021, Ethra bridges maritime real-world assets and decentralized finance through a two-layer architecture: an open, permissionless $SHIP ecosystem token and a separate, eligibility-gated regulated investment layer. Unlike concept-stage projects, Ethra is a real operator, not a marketplace, with actual ships, real cash flows, and in-house commercial and technical management.
