Introduction

An attestation or claim is the on-chain evidence that an attribute of a user's identity (e.g. residency; accreditation) is true. Attestations enable issuers to ensure prospective token holders meet their compliance rules. When an issuer sets compliance rules, their token automatically checks that the right attestations are in place for token transfers to occur.

In order for a prospective token holder to be able to hold a token, they need to meet all the compliance rules set by the issuer. To do this, attestations are added to their account that confirm they meet the token’s compliance rules. These are given by attestation providers, who may either be the issuer or other approved third parties. 

Through rules and attestations, Polymesh enables an issuer to automate the compliance framework applicable to their security tokens.

Attestations can be configured in two ways: on the Token Studio or the Polymesh Portal.

Scope types

• Identity: This scope is applied to a specific identity. This can allow an issuer to reuse the identity claims across multiple assets they have issued.
• Asset: This scope is applied to a specific asset. This is the most restrictive scope as claims must specifically be created for this asset, but provides the most granular control of identity claims.
• Custom: This is a custom scope type. A value is required.
