CryptoCred is a decentralized platform where:
- 🎓 Students can upload academic certificates, stored on IPFS, hashed and anchored on the blockchain.
- 🏫 Institutions can issue verified certificates directly to wallets.
- 💼 Recruiters can verify the authenticity of certificates without relying on third parties.
All this happens securely on-chain, powered by NFTs and IPFS magic. ✨
Academic fraud and fake degrees are a massive problem worldwide. Recruiters and institutions waste valuable resources verifying credentials.
CryptoCred eliminates these issues by creating a trustless, immutable, and decentralized system for certificate issuance and verification.
This system ensures:
- ✅ Authenticity of documents
- 🔒 Tamper-proof records
- 🌐 Instant and permissionless verification

- Connect Wallet
- Upload PDF Certificate
- Backend hashes file, uploads to IPFS, stores hash on-chain
- View and share verifiable public profile
- Register (pre-approved or admin-set)
- Upload student batch or individual certs
- Sign and issue via smart contract
- Visit student profile link
- View uploaded certificates
- Verify hash + IPFS integrity via on-chain data
- Hashing – File is hashed with SHA-256.
- IPFS Upload – File is uploaded to NFT.storage.
- Smart Contract – Stores metadata: IPFS hash, file hash, timestamp.
- Verification – Recruiters download cert, hash it, and compare with on-chain hash.
✅ Match = legit
❌ Mismatch = tampered
