Description
Meta ID is a Proof of Card Protocol leveraging the MetaMask card details to issue a Soulbound NFT (SBT) as a verified on-chain proof of KYC. It links the user's MetaMask Wallet and card to create a reusable, privacy-preserving identity layer. Meta ID provides utility across platforms for:
KYC Verification
Quick and secure verification of a user's identity without needing to repeat KYC across multiple platforms on multi-chain.
The SBT acts as a decentralized credential, proving the user has completed KYC.
Unlocking Rewards
Integrated loyalty programs using the card spending history.
Rewards or premium access for verified users on partner platforms.
Spending-Based Benefits
Tailored perks (e.g., cashback, discounts) based on specific spending thresholds tied to the MetaMask card.
Key Features
MetaMask Card Verification
Verifies the user's MetaMask card details, ensuring card ownership.
Soulbound NFT Issuance
Creates an SBT linked to the user’s wallet as a unique proof of identity and KYC.
Privacy-Preserving
Uses Zero-Knowledge Proofs (ZKPs) using Semaphore to verify the NFT without exposing sensitive KYC data.
Interoperability
Integrates with existing loyalty and identity systems across various platforms, enabling cross-platform rewards.
Reputation System
Tracks user behavior (e.g., spending patterns) and builds on-chain reputation, enabling advanced use-cases like exclusive access tiers or incentivized offers.
Progress During Hackathon
The complete project is build during last week. Our primary focus during the hackathon was centered around delivering a well-functioning MVP by combining rapid prototyping and integration. Here’s an outline of what we achieved: Back-End Infrastructure: Built and tested the card verification module using MetaMask SDK. Deployed a prototype of the smart contract for minting Soulbound NFTs. Front-End Progress: Developed UI for MetaMask wallet connection, card verification flow, and SBT minting. Created a basic rewards dashboard to showcase benefits unlocked using spending-based logic. Design Improvements Future-Focused Planning: Crafted detailed plans for enhancements, including: Privacy-preserving Zero-Knowledge Proof architecture. A scalable API layer for partner platform integration.
