Supported Pairs
CRX lets the taker lock a future rate on the pairs below. Every pair is cash-settled in stablecoin, USDC or EURC. The taker never takes delivery of the foreign currency.

When does a pair trade?
Only in its session, and every pair has its own. There is no network-wide schedule: each pair carries an on-chain calendar holding a timezone, per-weekday windows, and holiday overrides, and the desk's open/closed gate reads that calendar and nothing else.
The hours derive from the market behind each pair's price feed. CRX reads every rate from Pyth, an oracle network where exchanges and market makers publish their prices first-hand (Oracle (~3 min)). Marking and settlement both read that feed, and the network cannot mark or settle on a price the market is not making. A windowed pair trades only while its local market is open and printing live rates, and each market keeps its own hours.
What happens to a position overnight?
In session, a pair carries a live mark; out of session, it freezes against the last EMA mark. The calendar is the per-pair source of truth for both, and the same machinery runs either way; the only difference is which price it reads.
- In session: the pair carries a live mark. Variation margin and close-out both run at the fresh oracle price, and a close-out resolves at that price.
- Out of session (nights, weekends, holidays): the pair freezes against the last EMA mark. The position stays margined, and a shortfall that surfaces overnight still resolves through the risk engine.
A position is never left unmargined while its local market is closed for the night. See The Risk Engine (~3 min).
