First of all, you should know that trading on ETHERC or any other decentralized exchanges  incurs two types of fees:

  1. Trading fee: charged by ETHERC on all Market Taker trades.
  2. Gas fee: charged by the Ethereum network on all smart contract transactions.

Please note that order creation doesn't require paying a gas fee as it happens off-chain. However, order cancellation happens on-chain, so requires a gas fee. You can avoid this by setting your order to expire sooner rather than later.

ETHERC charges trading fees:

  • 0.3% for the market takers.
  • 0% for the market makers.
