The On-Chain Settlement Protocol for Maritime Receivables.
Transforming underwritten ocean freight time-charter cash flows into programmatic, ring-fenced private credit vaults.
Charter hire
Receivables, not vessel shares.
Private vault
Structured and monitored exposure.
Lockbox path
Subject to legal documentation and controlled escrow before funds reach the vault.
What is Supro?
An institutional-grade alternative debt settlement matrix engineered to bypass legacy banking friction for maritime private credit.
Decentralized clearing for maritime private credit
Supro functions as a clearing interface between stablecoin LPs, the vault, SPV-controlled lockbox accounts, borrowers, and programmable settlement logic.
- Stablecoin LPs receive vault exposure instead of vessel ownership claims.
- Underwriting stays tied to active Time Charter cash flows.
- Capital movement is structured through legal documentation and controlled accounts.
The underlying asset
Underwritten strictly against active Time Charter cash flows.
- Contracted cash flows: charter hire payments create the receivable base.
- Contract quality and payment behavior determine eligibility.
- No fractionalization or tokenization of vessel ownership.
Institutional real yield, not DeFi arbitrage
Supro avoids multi-layer leverage, synthetic loops, and circular lending. Yield is sourced from fixed, active ocean freight Time Charter hire distributions.
- Zero black-box loops.
- Direct contract transparency.
- 100% cryptographic traceability across charter agreements, payment milestones, and capital routing events.
Multi-layer over-collateralization
Receivables escrow plus corporate equity pledge give the credit structure deeper defensive safety without traditional asset-heavy operational drag.
- 100% locked receivables escrow through controlled lockbox routing.
- Corporate equity pledge from borrower ShipCo to the SPV.
- Title and asset-control recourse in structural default scenarios.
Audit-ready architecture for third-party verification
Programmatic waterfalls, cash reserves, and active marine telemetry data are designed to remain open to third-party accounting and verification systems.
100% locked receivables escrow
- Future contract cash flows bypass borrower bank accounts.
- Collection events are routed directly through a controlled lockbox.
- Each payment milestone can be mapped to transparent on-chain status.
Corporate equity pledge
- The borrower executes a corporate equity pledge directly to the SPV.
- In structural default, the pledge creates legal recourse to the vessel-holding corporate vehicle.
- Investors receive secondary asset protection without operational drag.
Boundaries
- No fractionalization or tokenization of vessel ownership
- No principal guarantees or synthetic fixed-return promises
- No pooling of unconfirmed or unvetted maritime assets
- No reliance on a single charterer narrative or counterparty

Common questions
Not yet. The Supro vault interface is in a controlled pilot phase. Use Contact to join the waitlist and be notified at launch.
The LP side is designed to be publicly accessible for stablecoin depositors once live — there is no gatekeeping on the investor side.
Yes. Borrowers go through strict KYB and physical asset vetting before any charter hire receivable is accepted into the credit engine.
Monthly transparency reports are paired with continuously updated on-chain share, NAV, and redemption data.
Funds move through a controlled lockbox / escrow path confirmed by financing documentation and a bankruptcy-remote SPV before any disbursement.
