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.
Turn manual document examination and slow back-and-forth into instant discrepancy detection and settlement.
01.
Issue the LC on-chain. The Trade Finance Documents module creates the credit with its terms as one authoritative record shared between banks.
02.
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.
Catch mismatches immediately. The Compliance Attestations module checks each document against the terms and flags any discrepancy the moment it is presented.
04.
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.
Pay on clean presentation. The Escrow and Conditional Settlement module releases payment automatically once all documents match the terms.
06.
Record every step. Issuance, presentation, discrepancy, and settlement are anchored, so any dispute is settled against a complete record.
Follow a single letter of credit from issuance through a flagged discrepancy to automatic payment.

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.
Automated LC handling is a horizontal capability. Here is how different actors rely on instant discrepancy resolution.
Examine documents automatically and resolve discrepancies in hours, replacing subjective manual checking and slow correspondence with a deterministic, auditable flow.
Key Asset Types
Present documents in structured form and see exactly what to fix when a discrepancy is flagged, getting paid the moment a clean presentation is accepted.
Key Asset Types
Trace an LC's full lifecycle from issuance to settlement in one anchored record, settling any dispute against complete evidence.
Key Asset Types
Whether you are bridging a bank's trade finance system or connecting corporates to present documents, Cerulea routes both into one automated LC record.
For banks on legacy trade platforms. Document and credit events are translated into signed on-chain LC transitions through the API gateway automatically.

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.
