NumTrade FinTech & Research Labs LLP is a research-driven financial technology studio.
We design and operate low-latency trading services, skill-based prediction engines, and
non-custodial payment infrastructure with escrow segregation, deterministic accounting,
and verifiable audit trails.
NumTrade is funded by Bayesrock Corporation. Bayespark DAO operates as a NumTrade subsidiary focused on non-custodial wallets and programmable settlement.
Legal scope
We develop and serve financial technology solutions exclusively for
Bayesrock Corporation and its subsidiaries, including
bayespark.com, shivpe.org, and projecthalley.org.
- Strategic backer: Bayesrock Corporation
- Operating entity: NumTrade FinTech & Research Labs LLP (Mumbai, India)
- Subsidiary program: Bayespark DAO — non-custodial payments, multi-chain rails
-
Skill-based prediction / contest engines
Deterministic scoring, provably-fair allocation, Merkle proofs, RBI-aligned escrow segregation, live odds and liability control. -
Low-latency trading & market services
Streaming order ingestion, idempotent state transitions, durable queues, position & P&L accounting, explicit recovery semantics. -
Non-custodial payments (Bayespark DAO)
Wallet orchestration, signed transactions, webhook/queue settlement, chain adapters with strict boundary contracts. -
Data & research pipelines
Tick/event ingestion, columnar storage, reconciliation rollups, reproducible research notebooks and model evaluation.
We do not ship monoliths. Systems are constructed as small, testable services with stable contracts.
- Determinism first — every state transition is reproducible from logs and inputs.
- Strong boundaries — ingest, score/match, settle, and audit are isolated services.
- Idempotency & replay safety — all mutations carry dedupe keys and versioned schemas.
- Typed interfaces — Protobuf/gRPC and JSON APIs are versioned and migration-driven.
- Observability as a requirement — metrics, traces, SLOs, cardinality budgets, red/black-box probes.
- Defense in depth — escrow segregation, immutable/WORM logs, policy KMS, least-privilege runtime.
We use multiple languages intentionally, chosen for their strengths on each layer.
- Go — realtime services, WebSocket hubs, engines, workers, gRPC APIs.
- Rust — proof/verification kernels, high-safety adapters, cryptographic primitives.
- C++ — latency-critical computation and simulation where metal-level control is required.
- Python — research pipelines, data tooling, ETL, statistical testing, notebooks.
- Haskell / OCaml — specification, property-based testing, and correctness-oriented components.
- TypeScript / React — client applications, admin consoles, and internal ops UIs.
- Node.js — API gateways, edge adapters, signing services.
- PostgreSQL, Redis, S3/Parquet — ledgers, queues/caches, archival lakes.
- Nginx, CloudFront, WAF — ingress, shielding, and distribution.
- Prometheus, OpenTelemetry, Loki — metrics, tracing, logging.
- GitHub Actions, Terraform, rsync — CI/CD and infrastructure automation.
| Layer | Responsibilities | Illustrative technologies |
|---|---|---|
| Edge / Ingress | TLS termination, WAF, rate limits, circuit breakers, request shaping | Nginx, CloudFront, WAF |
| API Gateways | AuthN/Z, quotas, request signing, schema routing | Go / Node.js gateways, JWT, HMAC |
| Realtime Svcs | WebSocket hubs, pub/sub, fan-out, presence, live odds | Go, Redis Streams, NATS |
| Core Engines | Matching/scoring, deterministic state machines, liability/escrow orchestration | Go, Rust, C++ (where latency demands), property-based tests in Haskell/OCaml |
| Settlement | Escrow disbursal, bank rails adapters, chain writers | Go workers, gRPC, chain SDKs, signed jobs |
| Data Plane | OLTP ledgers, append-only audit, analytics lake | PostgreSQL, Redis, S3/Parquet |
| Batch / Jobs | Rollups, reconciliation, backfills, simulations, model runs | Cron, Airflow or Temporal, Python pipelines |
| Observability | Metrics, traces, logs, anomaly detection | Prometheus, OpenTelemetry, Loki |
| CI/CD & Ops | Build, sign, deploy, config promotion, secrets | GitHub Actions, Terraform, rsync, KMS |
| Frontends | Client UIs, consoles, dashboards | React/TypeScript, Tailwind, CSR/SSR where appropriate |
| Web Apps / Portals | Informational pages, ToS, admin tools, light dynamic content | PHP, Django, simple SSR sites |
Technologies are indicative; exact stacks vary per product and regulatory context.
- Escrow segregation with policy-bound disbursals and explicit human-in-the-loop where mandated.
- Merkle-audited rounds and append-only internal logs; reproducible state from event streams.
- PII minimisation and encryption for customer and financial data.
- Key management via policy KMS and multi-stage signing for infrastructure and on-chain operations.
- Immutable snapshotting and versioned deployments for full traceability.
Core repositories are private to protect proprietary engines, market logic, and compliance artefacts.
We selectively publish public interfaces, SDKs, and documentation as needed.
