Each team will record a short video in English, demonstrating their project and showcasing their development and learning. A post will be made for each team, presenting a total of 8 unique projects. Lets give them Exposure. **Projects:** - 1. Merkle Tree Airdrop - 1. Web3 Affiliate Marketing - 1. Web3 Grades manager - 1. Fitness Dapp - 1. Web3 Bets - 1. Decentralized WAZE - 1. Superchain Donations - 1. Web3 Game **Submission Guidelines:** - **Title of the Post/Project:** Clearly state the name of the project. - **Brief Description:** Provide a concise description of the project’s goals and objectives. - **Team Members:** Include the names and blockchain addresses used during the course for each member.

**MAFI - Introducing the Web3 Brand Ambassador** **Team:** [Kenneth Walker](https://github.com/WalkerKenneth): 0x8A7Bb4Bd34c3E6906EfbCd3515551c0F4658e80f [Ricardo Bonilla](https://github.com/richbm10): 0x9E17D83De550DFD4585632E725fD92E72b9C3f4a [Oscar Astua](https://github.com/OscarAstua29): 0x7Bd09a8Ec7411Ca0C2Da67eD5797eb08e01Ab0a1 [Joseph Poveda](https://github.com/josephpdf): 0x0b25521dFa86D6dda99eDbd65f383ED6051891a6 **Video:** [MAFI - Web3 Project](https://youtu.be/BrHR9xDJc1o) **Problem** : There is a lack of transparency in conversions and attribution between multiple marketing parties, leading to mistrust and ineffective tracking of results across various marketing channels. **Solution:** Utilize the security and decentralization of the Optimism L2 Blockchain to transparently record and audit attributions and conversions of Brand Ambassadors in Affiliate Marketing campaigns. This creates a transparent network accessible to any party, enhancing trust and tracking efficiency. **Project Overview:** Mafi is a Web3 Affiliate Marketing solution that mirrors the goals of traditional web2 affiliate marketing but leverages the Optimism blockchain for transparent conversion tracking. Our solution involves three key roles: Client Brand Manager, Brand Ambassador, and Customer. **Platform Implementation:** 1. Client Brand Manager: - Create Affiliate Marketing campaigns. - Include Brand Ambassadors from our platform’s network. - Validate the MVP using account abstraction by creating a web3 wallet to minimize barriers to entry. 2. Brand Ambassador: - Access the Mafi platform to send affiliate requests or respond to client requests. - Authenticate by connecting their web3 wallet to our platform. 3. Campaign Process: - Once a campaign reaches the minimum number of affiliates, it is submitted to the blockchain. - We use an ERC1155 NFT collection and the MafiBrandAmbassador contract to track conversions and affiliates. - Each Brand Ambassador receives a unique deep link to share across marketing channels, attributing sales to their efforts. 4. Customer Interaction: - Customers click on the link, download the Mafi mobile app, authenticate, and purchase the NFT. - The purchase involves the MafiBrandAmbassador contract, splitting the payment: 5% commission to the Brand Ambassador, the remainder to Mafi. **Benefits:** - Public, decentralized records of conversions and attributions. - A global ranking system for Brand Ambassadors based on performance. **Contracts:** [MafiBrandAmbassador](https://sepolia-optimism.etherscan.io/address/0xe59cd0252a9b5298779ca53bcc6dba19d1662a6f) [SaprissaCentenoCollection](https://sepolia-optimism.etherscan.io/address/0xa192E5EFa6372B91cc04Bc31FC001a309D6adfd1) **Codebase:** [web3\_brand\_ambassador](https://github.com/richbm10/web3_brand_ambassador) ---
