Common questions about the decentralized order book.

Common questions about trading on a decentralized order book. Still stuck? Contact us.

Can I cancel an order on a decentralised order book?

Yes. You can cancel any open order at any time from the My Wallet section.

What are the fees?

By default, maker fees are 0.2% and taker fees are 0.5%. Each trading pair keeps its own rates, so a pair can differ from the defaults.

What's the difference between a maker and a taker?

A maker creates an order that sits in the book (a buyer or a seller) — they provide liquidity, so they pay the lower fee. A taker matches against an existing order, taking liquidity out of the book, and pays the higher fee.

Which fee does the UI show before I trade?

The fee is always charged on the token you receive, at the rates of the market you trade on: by default 0.5% for a taker and 0.2% for a maker. A swap is priced to take liquidity from the book, so it shows the taker rate. A limit order is checked against the live book: the part that would match straight away shows the taker rate, and the part that would wait in the book shows the maker rate. Someone might place or cancel an opposing order just before your transaction lands, so the final split can differ. A single order can also match at most 25 resting orders, and anything left over waits in the book as a maker order. The two rates are set separately for each market, so the maker rate can even be the higher one. Whenever the preview cannot tell whether part of your order will be a taker or a maker (the book has not loaded, or it is too deep to see in full), it shows the higher of the market's two rates, so the figure is never lower than what you will pay. Placing your order away from the current price makes it less likely to match as a taker, but another trader's order can still cross it before it lands, so it does not guarantee you will pay the maker fee.

How is an asset's price determined?

By supply and demand. Price tends to rise when there are more buyers than sellers, and fall when there are more sellers than buyers. The displayed price is simply the last completed trade.

Why didn't a suggested price appear when I switched tokens?

The suggested price comes from the last completed trade. If a market has no completed trades yet, there's no price to suggest.

What is a decentralised order book?

It's an order book that lives on the blockchain. Users place buy or sell orders at specific prices; those orders are recorded on‑chain. When a buy and sell match, the trade executes and the asset moves from seller to buyer — with no central operator in the middle.

What are the benefits?
  • Security — no single entity controls the book, so it's far harder to tamper with.
  • Transparency — every order and trade is recorded on‑chain, so the full history is public and verifiable.
  • Lower fees — without intermediaries facilitating trades, costs are typically lower than on traditional exchanges.
What are the risks?

As with any market, prices can be volatile, and a market with less liquidity can move more sharply. Always trade within your means.

Can I place both buy and sell orders?

Yes. A buy order says you want to purchase an asset at a given price; a sell order says you want to sell at a given price. When a buy and a sell match, the trade executes and the asset transfers from seller to buyer.
