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.
Turn FX exposure between batch initiation and settlement into a locked, verifiable rate.
01.
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.
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.
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.
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.
Remove the drift. Because the rate is locked and verified, the exposure between initiation and settlement is closed, giving cost certainty.
06.
Back the treasury record. The Compliance Attestations module attests the locked rate and settlement, supporting audit and internal controls.
Follow a single bulk payment run from rate lock through batch settlement to end-to-end verification.

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.
Locked-rate batch settlement is a horizontal capability. Here is how different actors rely on cost certainty.
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.
Key Asset Types
Receive batch payments settled at a fixed, verifiable rate, so overseas suppliers and employees are paid predictably and on time.
Key Asset Types
Attest that each batch settled at its locked rate, backing treasury controls and audit with verifiable end-to-end evidence.
Key Asset Types
Whether you are bridging a treasury system or feeding verified FX rates, Cerulea routes both into one locked-rate batch record.
For companies on legacy treasury systems. Payment runs are translated into signed on-chain batches through the API gateway automatically.

Building a batch FX system with rate locking, batch grouping, locked-rate settlement, and end-to-end verification from scratch requires treasury and FX engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

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.
