Imagine the power of knowing the trustworthiness of every DeFi user. This project lets you do exactly that! First, a user needs to verify they are a unique person through their World ID. The user then needs to connect their wallet and Lens profile. After the user finishes signing the agreement, the platform will receive all the relevant information related to the wallet and run through a credit evaluation algorithm where relevant criteria are selected by the community. The user will then get a credit score and an NFT to prove their trustworthiness to DeFi protocols and other users. The core of this project is to provide proof of a user's trustworthiness without revealing the person's real-world identity. This system will also provide incentives for good behaviors on DeFi protocols and social media.

This project can be divided into two main layers, (1) the algorithm that is used to calculate the credit score; (2) the on-chain data retrieving layer using the subgraph on Polygon. We used WalletConnect's React native client, Lens API for authentication on the frontend. All the data including the credit NFTs are stored on IPFS.
