Pricing and total cost
Makers are not charged trading fees. Taker fees use a market coefficient × P × (1−P), applied to notional with multiplicative discounts. The docs describe rates up to 1%, but also a $0.25 minimum fee, so a small trade’s effective percentage can be higher. Minimum order and withdrawal amounts are listed as $5. Trade match/settlement gas is covered; some other actions have user-paid gas.

What to check
- The $0.25 minimum fee remains even when discounts reduce the curve-based fee.
- Fees are assessed per matched fill, which matters when one order crosses several prices.
- A limit order is not automatically a maker.
- Points are separate from realized trading profit.
