FAQ

Short answers to the questions a treasurer asks before committing collateral. Each links to the page that owns the detail. For orientation — Sandbox, custody, what a taker trades — see the General FAQ (~2 min).

1What are the risks, and how is collateral protected?

The trade is opened against the CRX Network, and the risk engine locks collateral on both sides in one transaction — the taker's margin and the other side's lock together, or nothing opens. No one trades on credit. The collateral sits segregated in the on-chain vault, never on CRX's balance sheet, never lent or reused. If the other side's collateral no longer covers its book, the risk engine closes it out at the oracle mark and pays the taker from the closed-out party's locked collateral, never from the taker's own.

Sandbox environment. CRX runs today in a Sandbox on Base Sepolia, where balances carry no production value, and an independent security review is underway; treat every property as a stated design property until its report publishes. The full list, risk by risk: Risk Disclosures (~4 min).

2Will it be straightforward for an accountant to handle?

Yes. An NDF is a cash-settled forward: nothing is delivered, no local currency moves, and every flow is in the position's stablecoin, USDC or EURC. The books carry three kinds of entry — the margin posted (the firm's own asset, returned when the trade ends), the variation margin that clears P&L into the balance, and the settlement payment at maturity. Every one is a timestamped transaction on a public chain, and the app lists trades and settlements under History, each backed by a timestamped transaction on a public chain.

Tax treatment depends on the jurisdiction. CRX does not give tax advice.

3Can CRX plug into a firm's own systems?

Yes. There is no private data layer to integrate against: every position, margin move, and settlement is a public on-chain record that can be read or indexed directly, and the relayer exposes a REST API for quoting and trade history. A treasury system that can call an API or read a chain can carry CRX positions alongside everything else. Start at Quick Start (~5 min).

4How are funds accessed if CRX disappeared?

Directly, with the firm's own key. The collateral is held by the smart contract on Base, a chain CRX does not operate — it is never on CRX's balance sheet. Two paths stay open with no operator:

• An open position still ends. Settlement and the co-signed close are direct contract calls: the signatures land on-chain and free both sides whole, even with the relayer and every bot offline. See Closing Early (~2 min).
• The free balance is still withdrawable. The contract carries a direct withdraw call that pays the firm's own address. The gasless route in the app is a convenience, not the only door.

5How long does a withdrawal take?

One signature, no waiting window. The taker signs a withdrawal intent in the app — no gas — and the relayer releases the collateral on-chain to an approved recipient. There is no banking cut-off, no business-day window, no settlement queue.

Only the free balance is withdrawable: margin locked under an open position returns when that position settles or closes, and pending variation-margin gains are realized into the balance first. Profit comes out with the rest. The click-path: Withdraw (~1 min).

6What are the fees?

There is no platform fee. The firm price accepted is the whole cost of the trade: the rate carries the spread, and nothing is charged on top.

• Margin is not a fee. It is the firm's own collateral, segregated and returned when the trade ends.
• Requesting a quote costs nothing. An unsigned quote simply expires.
• Withdrawals are gasless. The taker signs; the relayer pays the gas.
