Batch FX Settlement Layer

Lock the rate.
Settle the batch.

Let companies lock an exchange rate for a bulk cross-border payment run and settle the whole batch at that rate, verified end to end. A rate is fixed the moment a batch is created, giving treasury certainty over costs between initiation and settlement.

The Foundation

The Execution Mechanics

Turn FX exposure between batch initiation and settlement into a locked, verifiable rate.

01.

Rate Lock at Creation

Fix the cost up front. The Oracle Feeds module captures a verified exchange rate the moment a batch is created and binds it to the whole run.

02.

Batch Payment Grouping

Move many at once. Payments to overseas suppliers or employees are grouped into one batch, so a single locked rate applies across every line.

03.

Locked-Rate Settlement

Settle at the fixed rate. The Escrow and Conditional Settlement module settles the entire batch at the locked rate, so a later market move does not change the cost.

04.

End-to-End Verification

Prove the rate held. Each line's settlement is checked against the locked rate, so treasury can verify the batch settled exactly as fixed.

05.

Exposure Elimination

Remove the drift. Because the rate is locked and verified, the exposure between initiation and settlement is closed, giving cost certainty.

06.

Compliance Attestation

Back the treasury record. The Compliance Attestations module attests the locked rate and settlement, supporting audit and internal controls.

The Batch Lifecycle

Follow a single bulk payment run from rate lock through batch settlement to end-to-end verification.

Smart Contract Anatomy

Cerulea decomposes batch FX settlement into modular contracts. Each layer locks a rate, groups the batch, settles at the locked rate, and verifies without exposure drift.

Applicability Across the Spectrum

Locked-rate batch settlement is a horizontal capability. Here is how different actors rely on cost certainty.

Corporate Treasury

Lock a rate for a bulk payment run and settle the whole batch at that rate, gaining certainty over cross-border costs instead of bearing FX drift.

Network & Execution Architecture

Whether you are bridging a treasury system or feeding verified FX rates, Cerulea routes both into one locked-rate batch record.

Track A: Treasury System Bridging

For companies on legacy treasury systems. Payment runs are translated into signed on-chain batches through the API gateway automatically.

Track B: FX Rate Feed

For verified FX rate providers. Signed rate feeds route through decentralized oracles directly into the rate lock at batch creation.

Technical Methodology

The legacy timeline reflects treasury FX integration benchmarks. Building rate locking, batch grouping, locked-rate settlement, and end-to-end verification for an average payment program takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your rate and batch rules into pre-audited WebAssembly binaries and provisions the batch FX ledger and settlement layer instantly.
