A digital wallet is a software that allows you to securely store and manage sensitive information, such as your login credentials, personal information, and financial details. With the help of cryptography and self-sovereign identity (SSI) principles, you can share your information with others without disclosing any sensitive data. It gives you complete control over your data and lets you decide what to share and keep private.
The Polygon ID Wallet is an example of a privacy-focused digital wallet that protects your identity and metadata using zero-knowledge proofs. This wallet interacts with issuers to fetch credentials and verifiers to share proof of these credentials. The Polygon ID Wallet app is built using a Wallet SDK, which allows other web3 wallets to add similar functionalities.
How to use PolygonID with DAO
PolygonID SDK and Wallet
Polygon ID SDK and Polygon ID Wallet App are key concepts to understand when developing the Polygon network. The Polygon ID SDK is a software development kit that provides core functionality for creating identity wallets. On the other hand, the Polygon ID Wallet App is an example implementation of an identity wallet built on top of the Polygon ID SDK.
Developers can use the Polygon ID SDK to create their own custom identity wallets or modify existing identity wallets using the features provided by the SDK. In the following sections, we will explore the Polygon ID SDK plugin and provide an example app to guide developers through the initial setup required for using the plugin. The example app will also illustrate the overall flow of the Polygon ID SDK functionality.

Iden3comm is a protocol that standardizes the communication between an Identity Holder, Issuer, and Verifier. It defines the syntax, rules, and semantics of data exchange to ensure the proper synchronization of all parties involved.
The protocol specifies the structure of messages, requests, and responses necessary for exchanging information. It supports various types of messages, such as authorization requests and responses, zero-knowledge proof requests and responses, credential requests for issuance and fetching, Iden3 messages for message fetch requests, revocation status request messages, and device registration requests.
In summary, Iden3comm provides a common language for exchanging information in the context of identity management, facilitating secure and efficient communication between all parties involved.

Difference between wallets
Polygon ID Wallet is distinct from other crypto wallets such as Metamask, Trust Wallet, Coinbase Wallet, and Ledger due to its focus on identity management rather than on-chain transactions. Unlike other wallets, Polygon ID Wallet is specifically designed to create and store unique identities that can be used for authentication with the Issuer and the Verifier. The Identity Wallet enables an Integrator to obtain and store credentials from Issuers and then present these credentials to the Verifiers as zero-knowledge proofs.
While other wallet encryption allows interaction with Ethereum and other blockchain technology networks using RPCs, Polygon ID Wallet functions solely to store credentials associated with an identity, unlike traditional wallets, which store cryptographic keys, the Polygon ID Wallet stores user identities based on the Baby Jubjub Key. This key generates the Polygon ID Identifier, the unique identifier for the wallet, in contrast to the Ethereum Wallet Address generated using the secp256k1 elliptic curve used in wallets like MetaMask.
