Problem Statement

BackgroundWhenever I, as a Web3 technology expert, am approached by community friends for help, someone always asks, "Could you help us issue an NFT for this event?" I usually reply, "Isn't that pretty easy? You can go to POAP or find a 721 contract, upload an image, and publish it." Their typical response is, "Oh, okay," and then nothing happens. It wasn’t until I participated in issuing NFTs for Wamao, the largest self-organized Web3 event in China, that things weren’t that simple. If we could have community tools like a Markdown editor that caters to programmers, writers, and students with different products, there would be so many scenarios and demands to address.ProductThis time we took it seriously! We built a seamless login system based on email, automatically creating Ethereum OP Mainnet accounts, allowing users to set up their communities and publish events with a single click. Participants can register on-chain with just one click; and the process for issuing event NFTs doesn’t require Excel to tally wallet addresses anymore. 😄 Thanks to the embedded Paymaster mechanism, there are no gas fees involved, and it's incredibly smooth. You can clone it for free to run locally or use the online version at: https://cos72.aastar.io.On SuperChain, as long as you join the community and receive a community member card, you can perform operations on any chain without gas payment awareness! This system also supports the automatic deployment of your AA account, allowing seamless transitions from the OP Mainnet to any SuperChain!Future ExpansionThe biggest issue for communities is the constant influx and outflux of people, making it difficult to accumulate engagement. However, with rapid user registration and community joining, followed by event sign-ups and on-site check-ins, users can earn more community points and redeem community benefits. This is a win-win for both the users and the community!

Solution

It is built based on ERC4337 and Superchain universal tech stack so that we can get an address consistency for the same account. We use a paymaster mechanism and an NFT gas card to determine who pays the gas seamlessly.We use ETHPaymaster and AirAccount which AAStar built. We use ENS V1 resolver to allocate the ENS to each account address. We are trying to use the Push Protocol, EPNS to help the community send some notifications to their membersWhish community be diversity and vitality, don't like a company!
