A financial platform that earns trust before it trades.

HELENA is being built in five controlled phases. Phases 1–2 — the security, data and operational foundation, and the market intelligence & quant engine — are delivered. Phase 3 (paper trading, portfolio accounting and the Risk Firewall) has begun: every order is simulated and never sent to an exchange. Live trading remains structurally locked.

Identity & access

Database-backed roles from OWNER to VIEWER, server-side permission checks, hardened sessions.

Secrets & audit

AES-256-GCM envelope encryption for exchange credentials and an append-only audit trail.

Market intelligence

Real exchange data, quality scoring, regimes and deterministic strategies that produce evidence — never orders.

Paper trading & risk

Simulated fills against real order books, an immutable ledger and a Risk Firewall that vetoes before anything is recorded.
