SQR
SQR is a platform for embedding invisible watermarks into product images, creating digital twin records, and optionally minting ERC-721 NFTs for on-chain provenance.What you can do
Embed watermarks
Encode invisible identifiers into any product image — surviving print, photo, and compression.
Register records
Create digital twin records with structured metadata tied to a unique watermark ID.
Mint NFTs
Anchor records on-chain with ERC-721 tokens on Ethereum Sepolia.
Scan & verify
Decode watermarks from photos to look up provenance and ownership instantly.
How it works
- Upload an image and provide product metadata
- SQR encodes an invisible watermark into the image and stores the record
- Distribute the watermarked image on packaging, labels, or digital assets
- Scan any photo of the label to decode the watermark and retrieve the record
- Optionally mint an NFT to anchor ownership on-chain
