Must swap ETH for WETH.

ETH and WETH are worth the exact same amount. 1 ETH = 1 WETH. The only difference is that WETH is “Wrapped Ether” —  a simple change which makes it tradable with all the other ERC20 tokens. Thus before using LoopringDEX, you need to simply swap some ETH for WETH. You can always change back whenever you’d like. Switching between the two happens through an on-chain transaction.

Note: above I did not have enough ETH to wrap into WETH

What are “tasks”? When should I take care of them?

Tasks (“To-Do’s”) pop up if your wallet’s token balance or WETH is insufficient for completing the order after your order is submitted. A notification will be shown on the “tasks”. Your order will be processed only if you solve the required tasks.
