How It Works
Trademarks NFT anchors proof of creation on Polygon by combining local hashing, IPFS storage, and an immutable on-chain registry record.
1) Hash locally (SHA-256)
Your file is hashed in your browser. The hash is a unique fingerprint used for verification.
2) Store file + metadata on IPFS
The file and its metadata are pinned to IPFS so the record can reference a permanent content address (CID).
3) Register on-chain
The registry stores the IP type, SHA-256 hash, timestamp, and metadata URI on Polygon Mainnet. Once written, the record is immutable.
4) Verify publicly
Anyone can verify the record using the on-chain data (and optionally IPFS). This provides an objective timestamp and reference.
