LC Automation Engine

Automate the credit.
Flag every discrepancy.

Move a digital letter of credit through issuance, document presentation, and payment automatically, with discrepancies flagged instantly. Automated checking triggers payment when documents match, cutting discrepancy resolution from days to hours.

The Foundation

The Execution Mechanics

Turn manual document examination and slow back-and-forth into instant discrepancy detection and settlement.

01.

Digital Credit Issuance

Issue the LC on-chain. The Trade Finance Documents module creates the credit with its terms as one authoritative record shared between banks.

02.

Structured Presentation

Present documents as data. Shipping and trade documents are presented on-chain in structured form, so a machine check can compare them to the credit terms.

03.

Instant Discrepancy Flagging

Catch mismatches immediately. The Compliance Attestations module checks each document against the terms and flags any discrepancy the moment it is presented.

04.

Discrepancy Resolution Loop

Resolve in hours. A flagged discrepancy is routed to both banks with the exact field at fault, replacing days of correspondence with a targeted fix.

05.

Conditional Payment

Pay on clean presentation. The Escrow and Conditional Settlement module releases payment automatically once all documents match the terms.

06.

Full LC Audit Trail

Record every step. Issuance, presentation, discrepancy, and settlement are anchored, so any dispute is settled against a complete record.

The Credit Lifecycle

Follow a single letter of credit from issuance through a flagged discrepancy to automatic payment.

Smart Contract Anatomy

Cerulea decomposes LC lifecycle automation into modular contracts. Each layer issues the credit, examines documents, isolates discrepancies, and settles without days of manual back-and-forth.

Applicability Across the Spectrum

Automated LC handling is a horizontal capability. Here is how different actors rely on instant discrepancy resolution.

Issuing & Advising Banks

Examine documents automatically and resolve discrepancies in hours, replacing subjective manual checking and slow correspondence with a deterministic, auditable flow.

Network & Execution Architecture

Whether you are bridging a bank's trade finance system or connecting corporates to present documents, Cerulea routes both into one automated LC record.

Track A: Bank System Bridging

For banks on legacy trade platforms. Document and credit events are translated into signed on-chain LC transitions through the API gateway automatically.

Track B: Corporate Presentation

For exporters and importers on a portal. A corporate wallet signs each structured presentation and routes it directly to the examination engine.

Technical Methodology

The legacy timeline reflects trade finance automation benchmarks. Building digital issuance, structured document examination, discrepancy routing, and conditional settlement for an average corridor takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your examination and settlement rules into pre-audited WebAssembly binaries and provisions the LC automation ledger and settlement layer instantly.
