We recently launched [Loopring Pay](https://loopring.org/#/post/loopring-pay-is-live-zkrollup-transfers-on-ethereum) - fast, free, and completely self-custodial ETH and ERC20 transfers on our zkRollup.
We've been blown away by the reception of this tool by the Ethereum community, and beyond. However, right now, the experience basically feels like an "internal transfer" on the [Loopring Exchange](https://loopring.io). You can see a 30 seccond video [here](https://twitter.com/loopringorg/status/1270397971667001344?s=20) of what it looks like.
We are hoping to give Loopring Pay it's own, purpose-built flow, that feels much more like simple payments, and less like an exchange environment. So we give the community that task.
This bounty is to build a Loopring Pay UI with the following requirements:
1. Responsive design (right now Loopring.io isn't mobile compatible, so mobile-friendly is important).
2. Have a Layer-2 balance page to display all layer 2 token balances
3. Have deposit/withdrawal/transfer history pages
4. Support deposit/withdrawal/transfers
5. Support a generic, configurable Web3 provider, and support Metamask as default.
6. The compiled code should be really tiny for mobile integration.
7. Use React as the frontend framework, no server-side rendering.
We are awarding 25,000 LRC (~$2.5k) to the winning bounty. We will give 3 weeks for the task.
zkRollup is a new (and very promising) technology for Ethereum. This is a great way to cut your teeth on the tech, and provide users a nice experience when they enter the Loopring zkRollup to escape main chain congestion.
We have just open-sourced the Loopring Exchange frontend (this very repo), so you will be able to see how to interact with the protocol and APIs from this. You can also have a look at the API [here](https://docs.loopring.io/en/).
Thanks, and good luck!
