Identity
Overview
Identity is at the core of Polymesh. All network participants must have an on-chain identity to interact with the blockchain and its assets.
Each identity:
- Is created through a Customer Due Diligence (CDD) process
- Is referenced by a pseudo-anonymous decentralized identifier (DID) e.g.,
0xfc0d2fc058d02c0a89c2cc2ff11726971dd39886a0b80ecfaa80fa3f196d65ce - Can hold assets in associated portfolios, claims, and permissioned roles
- Is controlled by a primary key and optional secondary keys

Key Concepts
Identity Creation & Verification
Identities are created through permissioned CDD service providers who verify user information, create an on-chain DID and issue CDD claims required for network access.
Asset Management
Native assets (excluding POLYX) held by users are associated with their identities and can be organized into portfolios. Each identity can hold multiple assets and manage them through different portfolios. Identities can also be granted agent permissions to perform specific operations on behalf of asset issuers.
Claims & Compliance
Identities can receive claims from other identities, which are used to enforce on-chain compliance rules for assets. Claims have specific scopes and can be used to represent various attributes like KYC status or accreditation.
Key Management
Each identity has:
- A single primary key with full control
- Optional secondary keys with configurable permissions
- Support for multisig keys as either primary or secondary keys
- Support for smart contracts as either primary or secondary keys
- The ability to create child identities
Keys can also enter into a subsidized relationship with another key to have it pay transaction fees on its behalf.
Access Control
Polymesh provides robust authorization and permission frameworks to manage access between identities and their keys.
