VeriCred+ 🎓

Delegated, Tamper-Proof Credential Management with AI Oversight

The Problem

Credential fraud is a $16 billion annual crisis:

• 60% of employers encounter fake credentials

• Traditional verification takes weeks and costs $50-200 per check

• Web3 complexity prevents mainstream adoption

• No standardized infrastructure for verifiable credentials

  ---

  Our Solution

  VeriCred+ combines AI-powered fraud detection, MetaMask Smart Account Delegation, and Monad blockchain to create instant, trustless credential verification. By leveraging Envio's real-time indexing, we transform credential management into a seamless, consumer-friendly experience.

ARCHITECTURE

How It Works

Set Up Delegation

Credential Issuance Flow

1. Issuer enters credential details - Recipient address, credential type, and metadata

2. AI Agent analyzes fraud risk - Queries Envio for recipient's on-chain history

3. GPT-4o generates risk score - Low/Medium/High risk assessment with recommendations

4. Delegation signature - Issuer grants permission to backend wallet (one-time setup)

5. Backend wallet mints credential - Executes transaction on Monad with ISSUER_ROLE

6. Real-time dashboard update - Envio indexes event and updates all dashboards

Key Innovation: Issuers never pay gas fees and never sign minting transactions - the backend wallet executes on their behalf using MetaMask Delegation.

Credential Verification

Instant verification in 3 steps:

1. Enter credential token ID

2. Query MongoDB + Envio for dual verification

3. See complete credential details with expandable history

Results: Sub-second verification with full audit trail of who verified when.

Holder Experience

Holders can:

• View all their credentials in one dashboard

• Share credentials on Farcaster with verifiable frames

• Access IPFS metadata and blockchain transaction links

• See credential status (Active/Revoked) in real-time

  Blockchain Integration

  Monad Testnet Transactions

  

  All credentials are minted as Soulbound NFTs on Monad Testnet:

  • Chain ID: 10143

  • Performance: 10,000 TPS, 400ms blocks, 800ms finality

  • Transaction Type: Legacy (EVM-compatible)

  • Gas Model: Backend wallet pays, issuer doesn't

    ---

    IPFS Metadata Storage

    

    Every credential's metadata is stored on IPFS for permanent, decentralized access:

    • Credential type and details

    • Issuance and expiration dates

    • Issuer and recipient information

    • Cryptographic proof of authenticity

      Envio Integration

      Real-Time Event Indexing

      

      Envio HyperIndex powers VeriCred+ with GraphQL queries for:

      • AI fraud analysis (queries recipient on-chain history)

      • Dashboard statistics (real-time credential counts)

      • Verification lookups (instant credential status)

      • Farcaster Frames (social media verification)

        ---
