Must exchange 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 exchange some ETH for WETH. You can always change back whenever you’d like. Switching between the two happens through an on-chain transaction.

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.

Build your own DEX with Loopring H5DEX

H5DEX is not only for crypto-wallets. Other companies and services can implement the solution to offer exchange functionality. This includes but is not limited to news platforms, stock/chart monitors, social communities, and WeChat public accounts. Even centralized exchanges can build a DEX on Loopring H5DEX and share orders, depth and liquidity among all Loopring protocol partners.

H5DEX is developer-friendly. At the functional level, the development cost of the partner can be greatly reduced, and the visual UI level supports simple and fast customization.
