# Architecture

- Frontend: Next.js renders issuance and verification views.
- Backend: Express exposes IPFS upload with optional pinning credentials.
- Contracts: ERC-721 certificate and issuer registry.
- Storage: IPFS CIDs pinned by gateway providers.

Data flow: issuer submits metadata -> backend uploads to IPFS -> contract mints token with CID -> verifier reads CID from chain and fetches metadata from IPFS.
