Fees

The DEX charges a fee when an order fills, and that is the complete list. There is no fee to open an account, no Quanta fee to deposit, no overnight charge for holding a position, and nothing stacked on top of funding. Traders who know other venues will want to hold that claim up against the small print, so this page is the small print.

Taker and maker

Each fill on the orderbook joins two orders. One was already resting in the book at a stated price; the other arrived and matched it. The resting order made the market and the arriving order took it. The side you were on sets the fee you pay.

Side	What your order did	Fee charged
Taker	Matched orders already in the book: a market order, or a limit order priced to fill straight away	Taker fee
Maker	Rested in the book as a limit order until someone else matched it	Maker fee

Both fees are a percentage of each fill's value, counted in USDC and deducted from your trading account at the moment of the fill. Opening and closing are both fills, so both are charged the same way, and the days in between carry no fee. Funding can run during those days, and the next section explains why it is not a fee. Makers typically pay less than takers on an orderbook, since resting orders are what give everyone else a price to trade against, and the schedule lists both rates side by side so you can compare them before picking an order type. A liquidation is a forced close; any charge for it is listed in the schedule and comes out of that position's margin, never beyond it.

What is not a fee

Funding is a transfer between longs and shorts, sized by the gap between the market and the index. Every unit one side pays, the other side receives, and none of it goes to Quanta (Funding covers how it accrues and why it matters on a collectors' market).

Network fees belong to the network. A deposit moves USDC from your Solana wallet into your trading account in a single transaction, with no separate approval. Its network fee, together with the fee for the message that carries the deposit to the trading infrastructure, is paid in SOL from your wallet, so keep a little SOL there. The deposit form shows an estimate before you confirm. Quanta charges nothing to deposit or withdraw. The trading infrastructure takes a fee on each withdrawal, and the withdrawal form shows it, along with the amount you will receive, before you sign. If you bring funds to Solana from another chain first, whatever the bridge or the origin network charges belongs to them (Getting started walks through the deposit).

Spread and slippage are trading costs rather than fees. The spread is the gap between the best bid and the best ask; slippage is how far a large order moves the price as it works through the book. You can see the spread on the market page before you trade, and the book shows the depth your order will pass through. Both go to the traders on the other side of your fill. Quanta neither earns them nor adds to them.

So nothing is hidden. A charge that is not in the table above and not in the published schedule is a charge Quanta does not make.

Where the fees go

Fees are how the indexes fund their own markets. One part goes to the index treasury: the two-sided liquidity a new market needs to open, and the insurance fund behind each market that absorbs losses beyond a liquidated position's margin (Margin, leverage and liquidation). One part funds operations: the index engine, the oracle and the people who run them. One part buys back and burns the Quanta token (The Quanta token).

Fee flow shows how the three parts connect and how the treasury feeds back into new markets.

The schedule

The taker and maker rates are market parameters. They are shown on each market page, next to the market's other parameters, and in the fee schedule. The schedule is versioned: every version carries a number and the date it takes effect, each new version is announced before it applies, and earlier versions stay readable, so any past fill can be checked against the rate that applied to it.
