How fees work

How transaction fees work

Every Ethereum transaction involves a gas fee which is paid to miners on the Ethereum network. On UCURRENCIES DEX, Ethereum transactions are required for depositing, withdrawing, and trading.

If you're using UCURRENCIES DEX with MetaMask, you can lower the gas price when you accept a transaction to pay a lower gas fee. We recommend a gas fee of 4 gwei if you don't mind waiting a few blocks for your transaction to confirm. If you're using UCURRENCIES DEX without MetaMask, the gas price is fixed at 4 gwei.

If you're not using MetaMask, you can set the gas price from the "Gas price" item in the account dropdown (upper right).

Without getting into too much technical detail, a 4 gwei gas price corresponds to the following overall transaction fees:

An important feature of UCURRENCIES DEX is that placing an order doesn't involve an Ethereum transaction. Placing an order involves signing a message, which doesn't cost a gas fee. This means that placing an order on UCURRENCIES DEX is completely free: there's no Ethereum transaction fee and there's no fee if the order trades. The one and only platform fee charged is a 0.3% fee paid by the person executing an order (paid in the instrument being sold). This fee goes directly to external smart-contract operators for providing order-book liquidity and functionality. Currently, UCURRENCIES DEX itself keeps no fees for itself whatsoever.
