What is Supro?
An institutional-grade settlement layer for maritime private credit — engineered to bypass legacy banking friction while keeping every dollar traceable.
Charter hire, not vessel shares
LPs get vault exposure to contracted charter payments — no fractional vessel ownership, no synthetic wrappers.
Ring-fenced private credit
Every underwrite ties to an active Time Charter contract with vetted borrowers and monitored exposure.
Real yield, not DeFi loops
Returns come from fixed ocean freight distributions — no leverage stacks, no circular lending, no black boxes.

How it works
From stablecoin deposit to programmable clearing.
One inspectable path connects on-chain accounting to offline legal protection.
Stablecoin LP
Deposits USDT into the Supro vault via Lagoon's ERC-7540 async flow.
Vault
Issues shares tracked by NAV. Capital allocated to underwritten receivables only.
SPV lockbox
Bankruptcy-remote account. Charter payments route here before touching borrowers.
Borrower (ShipCo)
KYB-vetted operator with active Time Charter contracts and equity pledge to the SPV.
Programmable clearing
Waterfalls, reserves, and redemptions execute in code — reconciled against every event.
Yield source
Institutional real yield.
Sourced from fixed ocean freight Time Charter distributions — not multi-layer leverage or synthetic loops.
Risk controls
Multi-layer over-collateralization.
Receivables escrow plus corporate equity pledge give the credit structure defensive depth — without the operational weight of asset-heavy funds.
100% locked receivables escrow
- Charter cash flows bypass borrower bank accounts.
- Collection routes directly through a controlled lockbox.
- Every milestone maps to on-chain status.
Corporate equity pledge
- Borrower ShipCo pledges equity directly to the SPV.
- Structural default triggers legal recourse to the vessel-holding vehicle.
- Secondary asset protection without operational drag.
