DPP · POLYGON · WEB3 IDENTITY

Publish the DPP on blockchain.

Connect a wallet, verify a Freename Web3 domain such as bag.digitalproduct, and register the cryptographic fingerprint of the user-created Digital Product Passport on Polygon.

What is registered: DPP SHA-256 hash, DPP ID, optional public URI and essential metadata. The full document can remain on your storage/IPFS. Blockchain proves integrity, timestamp and issuer wallet; it does not by itself certify regulatory compliance.

01 · DPP

Load the passport

The app tries to read the latest DPP created with the Web3Domain generator. You can also import JSON.

Signing remains in your wallet. Web3Domain never receives seed phrases or private keys. The app uses Polygon Mainnet.

03 · IDENTITÀ WEB3

Verify the wallet domain

Enter, for example, bag.digitalproduct. Freename resolver returns the token ID and the app verifies ownerOf(tokenID) on the Polygon FNS contract.

05 · PUBBLICAZIONE

Register the DPP on-chain

If you have a public URL or IPFS CID for the full document, add it. It is optional: the hash alone can still prove that a specific file matches the registered DPP.

Document URI / IPFS (optional)

I understand that blockchain registration is public and permanent. I confirm that I have the right to publish this data and that Web3Domain does not automatically certify ESPR compliance of the content.
