Trade Finance Engine

Digitize the paper trail.
Settle on compliance.

Present and verify letters of credit, guarantees, and financing documents on-chain, with payment released automatically the moment documents comply. A 5-day paper process compresses to same-day, and duplicate-document fraud becomes detectable.

The Foundation

The Execution Mechanics

Turn the most paper-intensive process in banking into an on-chain document and settlement flow.

01.

On-Chain Document Set

Digitize the LC dossier. The Trade Finance Documents module presents every document type on-chain, replacing physical dossiers couriered between banks.

02.

Automated Compliance Check

End manual examination. Presented documents are checked against the credit terms automatically, so both banks confirm compliance in hours instead of days.

03.

Conditional Settlement

Pay on match. The Escrow and Conditional Settlement module releases payment the instant documents comply, so the exporter is paid the same day.

04.

Duplicate Fraud Detection

Kill double financing. Each document's digest is anchored, so the same invoice or bill of lading financed twice across banks is detected instantly.

05.

Digital Document Signing

Bind every party. The Document Signing module captures each bank's and party's signature on-chain, replacing wet-ink endorsements.

06.

Multi-Bank Coordination

Coordinate issuing and advising banks. All banks in the LC share one record, so there is no back-and-forth over which version of a document is authoritative.

The Trade Finance Lifecycle

Follow a single letter of credit from issuance through document presentation to same-day payment.

Smart Contract Anatomy

Cerulea decomposes trade finance into modular contracts. Each layer issues the credit, presents documents, verifies compliance, and settles without couriered paper or unilateral document control.

Applicability Across the Spectrum

Digital trade finance is a horizontal capability. Here is how different actors put the on-chain document flow to work.

Issuing & Advising Banks

Examine and settle letters of credit against one shared document set, cutting a 5-day paper process to same-day while eliminating duplicate financing fraud.

Key Asset Types

  1. 1Letters of Credit
  2. 2Document Sets
  3. 3Settlement Proofs

Exporters & Importers

Present shipping and trade documents on-chain and get paid the same day documents comply, replacing a week of courier and correspondence with an instant flow.

Key Asset Types

  1. 1Shipping Documents
  2. 2Invoices
  3. 3Payment Receipts

Guarantee & Insurance Providers

Attach guarantees to a verifiable document trail, so a claim rests on anchored evidence rather than a reconstruction of paper records.

Key Asset Types

  1. 1Bank Guarantees
  2. 2Anchored Documents
  3. 3Audit Trails

Network & Execution Architecture

Whether you are bridging a bank's trade finance system or connecting corporates directly, Cerulea routes both into one shared trade finance record.

Track A: Bank System Bridging

For banks on legacy trade finance platforms. SWIFT and internal document events are translated into signed on-chain LC transitions through the API gateway automatically.

Track B: Corporate Document Presentation

For exporters and importers on a portal. A corporate wallet signs each document presentation and routes it directly to the shared LC contract.

Technical Methodology

The legacy timeline reflects trade finance integration benchmarks. Building on-chain document handling, automated compliance examination, conditional settlement, and duplicate-fraud detection across multiple banks takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your document and settlement rules into pre-audited WebAssembly binaries and provisions the trade finance ledger and settlement layer instantly.
