Spot trading
Order books, swaps, how a swap picks its venue, and slippage.
Every pair of native tokens, and any token against native QRDX, can trade in two venues at once: an order book and one or more pools. Both are part of the chain, so a trade is final when a block includes it.
Markets
trade.qrdx.org lists every market with a pool. A market's URL names it: verified assets by name (/trade/btc/usdc), anything else by token address. Anyone can create a token with any name, so the site marks unverified tokens and the wallet always shows a token's address next to its symbol.
Native QRDX trades directly; there is no wrapping. Its side of a trade settles in your QRDX balance.
Limit orders
A limit order rests on the book until it fills or you cancel it. While it rests, its funds are escrowed: a buy holds the quote amount (price × size), a sell holds the base amount. Cancelling refunds the escrow.
- Pick a market and the Limit tab.
- Enter a price and a size; the form shows the total and your available balance.
- Press Buy or Sell and approve in the wallet.
The order appears in Open orders once a block includes it. Several orders can be placed before the first is included: the wallet tracks the nonces it has submitted.
Managing open orders
- Edit (the pencil) changes an order's price or size. On a network with the 2026-10 trading features it changes in one step (
MODIFY_ORDER), and a smaller size at the same price keeps its place in the queue. On an older network the order is replaced: cancelled, then placed again at the new terms, one signature each; the new order joins the back of the queue, and if the cancel lands but the new order is refused, no order is left. - Cancel all cancels every open order on the list. With the 2026-10 features it is one approval and one transaction, all or nothing; before them each cancel is its own transaction, so the wallet asks for each.
Stops, time in force and hidden orders
Where the network runs the 2026-10 trading features:
- The Stop tab places a stop-loss or take-profit that waits for the pair's last trade to reach its trigger, then trades as a market order (at most 10 % through the trigger) or a limit at the price you give. Its funds are locked when you place it and come back if you cancel it (the Stops tab).
- Limit orders take a time in force (GTC, Post only, IOC, FOK), and can be hidden or an iceberg.
- A buy can carry a TP / SL: one sell trigger that holds exactly what the buy bought, the first of the two to fire cancelling the other.
The same works for perps orders.
Swaps and market orders
A swap spends a fixed amount and receives whatever the best venue pays:
- each of the pair's pools, and
- the book, walking the bids when you sell the base asset or the asks when you buy it.
The swap settles entirely with the venue that pays the most. A pair with no market of its own is routed through up to three others; on a network with the 2026-10 features that is one swap through the whole path, delivering at least the minimum or nothing. Before you sign, the site asks the node for an exact quote and sets minimum received to the quote less your slippage tolerance (0.5 % by default). If the price moves past that before the block, the swap fails and nothing changes, except the small transaction fee.
Every operation is all-or-nothing
A swap that would receive less than its minimum, an order you cannot afford, or a cancel of someone else's order is refused whole. The chain records the failure; your balances do not change except for the fee.
Alerts
The bell next to a market's name sets a price alert: above or below a price in the market's quote asset (USD for perps). The site checks it against the last price while a QRDX Trade tab is open and tells you once, with a browser notification if you allow them, and then removes it. You are also told when one of your resting orders fills.
Fees
- Pool fees depend on the pool's tier: 0.01 %, 0.05 %, 0.3 % or 1 %. 70 % go to the liquidity providers in range, 30 % to the protocol.
- Transaction fees are paid in QRDX and burned: about 0.00004–0.00015 QRDX per operation, whether it succeeds or fails. On networks with the 2026-10 release, trading operations (orders, cancels, edits, stops, swaps) go free while your account has free actions left (10,000 to start, more as you trade; it needs 0.025 QRDX or 10 of perps equity to use them).
- Book fees follow your 14-day perps volume: 0.05 % taker and 0.02 % maker at first, lower from 5M.
Charts and data
Prices, candles, trades and 24-hour statistics come from the chain's own fills and pool swaps. The order book's Depth view draws the book as cumulative size against price; click it to use a price in the order form. Where a token has an outside market, the site also shows its USD index price from public exchanges, labelled as reference data. Nothing is generated or padded.
