We are thrilled to have you join us in building unique discoveries with Scroll Canvas, a new product designed for ecosystem projects to interact with users in a more tailored way.
Try Canvas at scroll.io/canvas
Scroll Canvas allows users to showcase on-chain credentials, status, and achievements called Badges issued and collected across the Scroll ecosystem. Users can mint a non-transferable and unique personal persona to collect and display their Badges.
- Canvas: Each Canvas is a smart contract minted through the
ProfileRegistrycontract by the user on Scroll’s website. - Badges: Attestations of achievements and traits verified through the Ethereum Attestation Service (EAS), issued by different projects and the Scroll Foundation. Badges are wallet-bound and non-transferable.
Differences between attestations and NFTs:
| Attestation | NFT |
|---|---|
| Witness Proofs | Tokenized Assets |
| Non-transferable | Transferable |
| Recorded on disk (blockchain history) | Recorded in memory (blockchain states) |
| Prove ownership at a point in time | Exercise custodianship of an asset |
