Every certificate and timestamp created with EMOZ is recorded on Polygon, a public blockchain. The smart contract that powers this process is open, verified, and inspectable by anyone in the world — including you, your legal team, or any independent technical expert.
The contract
EMOZ uses a single smart contract for all certificates and timestamps. Its source code is publicly available and verified on Polygonscan:
"Verified" on Polygonscan means that the source code has been independently confirmed to match the deployed contract — what you read is exactly what runs on the blockchain.
Soulbound NFTs: immutable by design
Each EMOZ certificate is a soulbound NFT. Soulbound means the token is non-transferable and non-deletable by contract: it cannot be sold, moved to another wallet, or destroyed. This is enforced at the smart contract level — not by EMOZ's policies, but by code that runs autonomously on the blockchain.
Once your timestamp is created, it is permanent. EMOZ cannot alter it, delete it, or modify the record — and neither can anyone else. The blockchain timestamp is the proof.
How to audit the contract
You do not need to be a blockchain expert to understand or verify the contract. Here are three options depending on your technical comfort level:
Read it directly: visit the Polygonscan link above and read the Solidity source code under the "Contract" tab. If you or your team have Solidity or general programming knowledge, the logic is straightforward.
Ask an AI: copy the contract source code and paste it into ChatGPT, Claude, or Gemini with a prompt like "explain what this smart contract does in plain language". You will get a clear, plain-language explanation of exactly what the contract can and cannot do.
Engage a third party: any blockchain or smart contract auditor can review the contract on your behalf and provide a formal written assessment. The contract address and verified source code are all they need.
Full transparency
EMOZ's approach to transparency is structural: the rules that govern your certificates are written in publicly verifiable code, not in terms of service that can change. The blockchain record is independent of EMOZ as a company — it exists and is verifiable regardless of us.
