What is an NFT certificate?

An NFT certificate is a blockchain-verified digital credential that proves course completion and cannot be altered, duplicated, or tampered with.

Which blockchain does Blockready use?

Blockready issues all its NFT certificates on the Polygon blockchain, a fast and eco-friendly Ethereum Layer-2 network.

Do I need MetaMask to receive my certificate?

Yes. Students need a MetaMask wallet to receive the NFT certificate. Wallets provide the public address required for minting.

Can employers verify my certificate?

Yes. Employers can verify ownership on the Polygon blockchain, on OpenSea, or through any supported crypto wallet.

Is the NFT certificate transferable?

No. NFT certificates are soul-bound credentials tied to your wallet and are not intended to be transferred or resold.

What happens if I lose access to my wallet?

If you lose your recovery phrase and lose access to your wallet, the NFT certificate stored in that wallet cannot be recovered. Always store your recovery phrase safely.

How It Works

How Students Claim Their NFT Certificate

Follow these quick steps to generate your blockchain-verified NFT certificate after completing your course.

Set Up a Crypto Wallet (MetaMask)

Download the MetaMask app and create your wallet. Write your secret passphrase on paper and store it securely — losing it means permanently losing access to your wallet.

Create an OpenSea Account

Using the browser inside MetaMask, visit opensea.io and connect your wallet. Your NFT certificate will appear there once minted.

Add the Polygon Network

Add Polygon PoS by entering:
RPC URL: https://polygon-rpc.com Chain ID: 137 Currency: MATIC

Send Us Your Wallet Address

Copy your public wallet address from MetaMask and provide it to us. We will mint and deliver your NFT certificate directly to your wallet.

For Employers

Directions for Employers

Verify a candidate’s NFT certificate quickly and accurately using the Polygon blockchain.

Ask the applicant to share their public wallet address (MetaMask or any crypto wallet).

Search the address in the Polygon PoS Explorer to view their NFT credentials.

Confirm the presence of the official Blockready NFT Certificate in their wallet.

Ensure the NFT has been transferred from the Blockready issuing wallet to the applicant.

The certificate is valid if the NFT is visible, immutable, and belongs to the candidate.
