Gas is ETH that is consumed to perform any on-chain transaction on the Ethereum network. This includes trades, cancelling orders, enabling token allowances, and wrapping ETH. This fee is calculated by multiplying the gas price and gas required. This fee does not go to RADAR RELAY, but to the network miners. Please note that gas prices are typically suggested by the application, but can also be set by the user.
The price you set for gas directly correlates with the speed of your transaction. Orders with higher gas prices (relative to the rest of the network) are generally mined faster. Network gas prices are dependent on how busy the network is.
