Sismo

With Sismo, users can create a broad set of attestations that document their reputation and achievements across supported apps and protocols.

These attestations can unlock premium features within gated services or serve as verifiable proof of trust for various interactions across ecosystems.

Attestations are issued as Non-Transferable Token (ERC1155) representations called Badges, and for every attestation generated, an associated Badge is provided to visibly represent that credential.
