Markets, agents and cross-chain settlement share one QRX identity layer.

QRX combines a native order book, delegated automation identities, BTC Light/SPV and Quantum Swap foundations without pretending an external-exchange balance is native QRX liquidity.

Native Markets

QRX-native limit orders, candles, trades, order-book state and order controls instead of embedding an exchange widget as the market itself.

Agents

Automation identities can be constrained by market allowlists, trade values, daily limits, expiry and explicit permission classes.

Kraken gateway

Optional external execution uses separately configured credentials/permissions and opt-in live trading paths. Paper analysis is not silently turned into a live order.

Quantum Swaps

QUB/BTC cross-chain settlement is built around HTLC and Bitcoin-SPV foundations with explicit deadlines, funding transaction binding and refund/redeem paths.

order / session → hashlock + refund conditions → BTC funding → SPV verification / confirmations → QUB-side settlement → redeem OR timeout/refund

BTC Light

The wallet uses a separate Rust BTC light service rather than embedding a full Bitcoin Core node. QUB keys, Bitcoin keys and the respective synchronization paths remain distinct concepts.

Reorg handling and Bitcoin header/retarget validation belong to the SPV security path — not to a GUI timer.
