Project Description

Mome is a social 2.5 platform as it serves as the bridge between Web2 and Web3 social apps. It combines the familiar and user-friendly aspects of traditional Web2 social media platforms with innovative Web3 technology and gamification. By doing so, it introduces users to the world of blockchain and decentralized content ownership while providing a seamless and accessible transition from the centralized Web2 social media experience they are accustomed to.

Each day, a new time capsule is opened where users can post and upvote content. At the end of the day, the top 12 moments, determined by user votes, are permanently sealed on the blockchain as a single NFT. Users log in via Worldcoin and Metamask, ensuring a secure and personalized experience. Users have the ability to mint their own posts into individual ERC-6551 NFTs. This feature enables content creators to tokenize their contributions uniquely and have full ownership of their moments.

How it's Made

Our hackathon project is an innovative exploration of blockchain and decentralized technologies. Upon their first login, users can authenticate themselves using either Metamask or Worldcoin, and are prompted to create their own account abstraction wallet with ERC6551 capabilities. They have the option to choose between SAFE and Biconomy for account abstraction solutions, which also allows for gas sponsored transactions, showcasing the potential of this technology.

We've designed our platform to be user-friendly. Images are stored through IPFS and retrieved via Airstack, ensuring quick and efficient access. Additional user information is obtained through Next ID, providing a comprehensive user profile.

Our platform utilizes Chainlink automation to streamline operations and deliver notifications through the push protocol. We have chosen Quicknode as our RPC provider for its reliability and performance.

While we've made efforts to ensure the security of our project, we acknowledge that due to the nature of the hackathon, it may not be as robust or secure as a fully developed product. We encourage users to keep this in mind.

Our contracts are deployed on LINEA, Gnosis Chain, and Polygon Mumbai. We have a project plan in place to ensure smooth implementation and integration of these technologies, and we're prepared to tackle any potential challenges that may arise.

This project is an exciting opportunity to explore the potential of these technologies and we're eager to see how it evolves. We welcome any feedback and suggestions.
