Resonix FinancePricing · Risk · Settlement

Computational infrastructure for pricing, risk, and settlement.

A PDE pricing engine that doesn’t time-step. Arithmetic that’s bit-identical across every desk. Single-solve uncertainty quantification for the overnight risk run. And an evidence base built to survive model validation.

Finance capabilities

One computational engine. Six domains it changes.

The same deterministic solver, evidence-based tooling, and audit-grade research platform show up across derivatives pricing, overnight risk, card authorization, reconciliation, model risk, and regulatory capital.

Derivatives Pricing

PDE pricing without time-stepping

Every options library reduces to integrating a linear PDE in time - and every library time-steps it. SolvLRDE computes the answer as a single contour integral in the Laplace domain, independent of maturity and stiffness. One LU factorization, reused across every strike, every maturity, every scenario in the same vol bucket. 5–40× faster than scipy BDF on benchmark workloads, with sub-basis-point agreement.

SolvLRDE

Overnight Risk & xVA

The batch that finishes before the bell

Overnight portfolio valuation, VaR, Expected Shortfall, and xVA fan-outs all bottleneck on the same inner loop: re-price every instrument under every scenario. SolvLRDE’s LU amortization across scenarios makes the fan-out structurally cheaper than any time-stepper. Paired with SolvSRK-UQ’s single-solve uncertainty quantification, the entire risk run - prices and confidence intervals - lands before the opening bell.

Card Authorization & Payments

Bounded intelligence on the auth message

Card networks compress a rich upstream picture into twenty standardized fields before the issuer decides. Moridain sits on the network, extracts ten bounded intelligence signals from the full picture, and delivers them alongside the standard message. Banks running rules engines outperform banks running machine learning - with a tenth of the regulatory exposure.

Cross-Desk Reconciliation

Bit-identical arithmetic across every desk

The front-office pricer, the risk engine, the back-office settlement system, and the regulatory report all compute on different hardware and produce slightly different numbers. SolvNum is a deterministic real-number primitive that produces bit-identical arithmetic across x86, ARM, GPU, and WebAssembly. One SHA-256 receipt proves every desk agrees.

Model Risk & Audit

Solver decisions that survive SR 11-7

Model risk management requires knowing why a particular solver was chosen and whether it is appropriate for the system it solves. SolvScout fingerprints your ODE/PDE system and benchmarks every candidate solver against it - dead zones called out, not hidden. SolvJump study runs and SolvSRK proof bundles archive the decision for replay. “Why this solver?” has a defensible answer at model validation.

Regulatory Infrastructure

Basel III/IV, FRTB IMA, deterministic replay

Regulatory capital calculations under FRTB IMA require reproducible risk numbers across systems and time. SolvNum’s cross-platform determinism means the approved model, the production run, and the audit replay produce the same bits. SolvJump and account release bundles provide the replayable evidence trail. The combination gives model-risk and compliance teams a turnkey argument for regulatory acceptance.

The product line

The finance product line on top of one computational engine.

Each product brief below opens with a scenario your team will recognize, then walks through what it is, who uses it, why it’s defensible, and how the claims survive model validation.

SolvLRDE - PDE Pricing Without Time-Stepping

Answer at time T without paying for every micro-step in between.

Long horizons and stiff linear structure punish time-marching solvers — you pay in steps, in stiffness, and in repeated factorizations across scenarios. SolvLRDE targets the linear response directly so scenario grids, strike ladders, and EMTP-style studies scale with factorization reuse, not with horizon length.

Open product brief
Single trajectory with a calibrated uncertainty envelope, fast enough for overnight risk.

SolvSRK-UQ for Financial Risk

Uncertainty bands without a Monte Carlo farm.

Certification, risk, and autonomy teams need error envelopes — but thousand-run Monte Carlo grids miss program milestones. SolvSRK-UQ delivers calibrated uncertainty alongside the trajectory in one pass, fast enough for control loops, overnight risk batches, and evidence packages that auditors can reproduce.

Four financial systems - front office, risk, settlement, audit - hashing to the same SHA-256.

SolvNum - Deterministic Arithmetic for Finance

Plan, flight, and audit replay agree — provably.

When three teams run the same mission math on three platforms and get three different answers, the argument is never about physics — it is about arithmetic. SolvNum gives you bit-identical reals across CPU, GPU, and WASM with a cryptographic receipt, so V&V, coalition replay, and capital models stop fighting floating-point drift.

Moridain for Card Authorization

Decisions get context the wire was never designed to carry.

Standard messages throw away the upstream picture before your rules engine or fusion node sees it. Moridain puts bounded intelligence back on the rail — so fraud, fusion, and operator queues rank on signal, not on whoever shouted loudest in the compressed feed.

SolvScout

Stop guessing which solver your model actually needs.

The wrong integrator costs months of false confidence before a stiff cell or noise case fails in review. SolvScout fingerprints your system, benchmarks every serious candidate on your problem, and shows a ranked table — including when a competitor wins — so model validation starts from evidence, not habit.

SolvJump

Shortlist integration candidates in minutes; confirm in hours—not weeks of sweeps.

Integration programs bleed calendar on hand-rolled parameter marathons and configs that only survive until the next variant. SolvJump ranks plausible integrator settings in minutes on the bench, then drives SolvSRK proof runs on finalists so you sign off in hours—not days or weeks babysitting sweeps.
