# Clique Attestation SDK Attestations are like digital records that act as proof or a stamp of approval on information provided by one party about pretty much anything. In our case attestations are statements made by an issuer-node about a subject. The subject can be an EVM address, or a VC, or an IPFS hash, or even another attestation. We use attestations because they are versatile and designed for composability and interoperability, they can vouch for a multitude of information types. Some great documentation has been done already by our friends over at [EAS](https://docs.attest.sh/docs/welcome) and [Verax](https://docs.ver.ax/verax-documentation/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
