Trading on StellarX is totally free. We charge no fees and take no percentage.
In fact, while the Stellar network charges a flat per-transaction fee as an anti-spam measure, the fee is so low (0.00001XLM) that we refund it out-of-pocket for every trade made on StellarX. Network fee refunds are bundled into a single payment and issued each week.
However, when you deposit into StellarX via one of our deposit partners, they may charge a fee for the service. We don’t, but they might. We will always let you know about those fees in the interface.
