FAQ

Questions, answered.

What is NYX Suite?

NYX Suite is the operating system for emerging fund managers, crypto and multi-asset. It connects to your exchanges, wallets, and brokers, runs a real double-entry shadow ledger alongside your fund administrator, strikes deterministic NAV, accrues fees, monitors risk, and generates LP reports automatically. Your administrator stays the official book of record; what Nyx compresses is the internal back-office tooling and workload around it: a stack that typically runs well over $300,000 a year, starting at $2,500 a month, banded by fund AUM.

Who is NYX Suite for?

NYX Suite is built for solo and small-team fund managers running roughly $1M to $50M in AUM, crypto-native funds and multi-asset managers with a crypto sleeve, who need institutional-grade accounting, reporting, and risk monitoring without building an internal finance and operations team around their existing fund administrator.

How much does NYX Suite cost, and how does that compare to a fund administrator?

NYX Suite is banded by fund AUM: $2,500/month under $25M, $4,000/month from $25M to $100M, and negotiated (from $6,000/month) above $100M, plus a $3,500 one-time implementation fee, with a 10% discount for annual prepayment the only discount offered. Billed by invoice, net 30, via bank transfer: no card checkout and no self-serve signup. No per-seat fees and every feature is included at every band: the ledger, risk desk, reports, and compliance tools are not separate add-ons. Your price never changes mid-term; re-banding happens only at the 12-month renewal, using your fund's own reported AUM. For context, a comparable fund's operating stack (a finance hire, a fund administrator with a $25K–$60K annual minimum, and a compliance advisor) runs over $300,000 a year. Nyx does not displace the administrator, who remains your official book of record; it compresses the internal tooling and month-end workload built around them.

What is "shadow accounting," and does NYX Suite replace my fund administrator?

No. NYX Suite runs a genuine double-entry ledger (append-only, balanced, audit-traceable) that reconciles against your exchange and wallet data in real time. It is a shadow book that sits alongside your official administrator, not a replacement for one. The value is that you (and your LPs) get an institutional-grade, always-current NAV and audit trail between the administrator's periodic statements, and a second set of numbers to catch discrepancies early.

Is NYX Suite secure, and does it have trading access to my funds?

NYX Suite is read-only and never places trades or moves funds. You connect read-only exchange API keys and public wallet addresses; keys are encrypted with AES-256-GCM, accounts support TOTP two-factor authentication with backup codes, and Nyx never requests withdrawal or trading permission. Your capital stays entirely under your control.

What asset classes does NYX Suite support?

NYX Suite prices 13 asset classes inside one shadow ledger. Digital assets (crypto and stablecoins) are live-priced across 95 exchanges and 21 blockchains. Equities, ETFs, and funds price end-of-day via a market-data feed. FX, commodities, and futures price against a registered symbol. Bonds, options, private holdings, and real assets price from a manager-entered fair-value mark, timestamped with provenance and approved through maker-checker before it can move NAV. Every class books into the same double-entry ledger and the same NAV strike, alongside stock brokers: Alpaca, Tradier, Interactive Brokers, and SnapTrade (which reaches Robinhood, Schwab, Fidelity, and more).

Can my investors see their own numbers or ask questions directly?

Yes. Every fund gets a read-only LP portal where each investor sees their own capital account, isolated at the database level so one LP can never see another's numbers. Investors join by invite-only magic link (no password to manage) and can optionally ask questions through bots on Telegram, Slack, or Discord, with dollar figures shared only when you enable full disclosure for that channel.

Does paper trading affect my real NAV?

Nothing from a paper or simulated account ever touches your real NAV. If you connect a TradingView or Alpaca paper-trading feed, Nyx keeps it in a completely separate, clearly labeled statement. It cannot post to your real positions, AUM, LP reports, alerts, or ledger under any circumstance.

Can NYX Suite build and backtest trading strategies?

Yes. NYX Suite's Strategy Lab lets you build a trading strategy with a visual node-graph builder or a sandboxed JavaScript code node, then run it through a deterministic backtest engine. The same strategy and the same data always produce the identical result. You can test long and short positions with up to 3× leverage and realistic costs (margin interest, funding, a modeled liquidation path), validate with walk-forward out-of-sample folds, and run portfolio backtests across multiple strategies as one book. An AI improve loop (strategy_improve missions) has the Analyst critique a strategy against a benchmark library and propose revisions you approve. Backtests are simulation, strictly segregated from your fund: they never touch real NAV, positions, or LP reports, and Strategy Lab, like the rest of NYX Suite, remains read-only and never places a trade.

Does NYX Suite help with Form PF, K-1s, or tax reporting?

Yes. NYX Suite exports a Form PF data-readiness package (a structured summary plus monthly series covering the categories the form requires), tracks tax lots under your elected cost-basis method (average, FIFO, or HIFO), and generates tax-gains and tax-capital CSVs alongside a K-1 data package. These are data-handoff exports for your preparer, not a filing service.

Can I try NYX Suite before paying?

NYX Suite does not offer a free trial. Instead, it offers a paid parallel-run pilot: Nyx runs alongside your existing fund administrator for three month-end closes, and you get a full refund if it doesn't reconcile. The pilot runs for three consecutive month-end closes at your band's normal monthly rate, and the $3,500 implementation fee is deferred until you convert to the annual agreement, not waived.
