Lit Credential Store

ℹ️ Introduction to the External Data Access Control & Credential Module

Today, diverse teams building in Web3 require access to third-party off-chain data. This data is often personal in nature and touches various regulatory frameworks including GDPR. Authenticity, access control and encryption of this data is necessary - currently there are no standard methods for enabling this.

The External Data Access Control & Credential Module is a framework and developer toolkit for…

• Connecting to existing decentralized identity (DID) systems
• On-ramping third-party off-chain data and creating an attestation of authenticity for said data, associated with a specific DID
• Managing access control to the third-party data

Problem:

• Many teams need to bring in off-chain personal data for use in their DAPP
• Off-chain information often includes sensitive personal data that must be accessed and controlled for regulatory compliance and privacy reasons
• There is no accessible method for teams to import off-chain personal data and natively gate access control

Solution:

• A tool and standard framework that lets developers create diverse access-controlled off-chain data attestations
• A system that can be configured to pull in data from any third-party source
• A system that can be compatible with existing DID and user identity solutions

Getting Started

First, copy/paste and fill the .env.example as .env.

You can then run the development server:

bun install && bun run dev

ps: bun is needed because yarn, pnpm and npm generates an error with the contracts-sdk package. See this issue for more info.

Open http://localhost:3000 with your browser to see the result.

File structure

ps: it's a nextjs project created using create-next-app.

Key files:

• src/app/credentials/[credId]/CredentialPage.tsx: Main react component for credential management.
• src/services/CredentialService.ts: Interface for credential services.
• src/services/GitHubService.ts: GitHub integration implementation (our example).
• src/utils/: Utility functions for IPFS, encryption, and signatures.
• src/utils/lit-utils: Utilities for interacting with LIT
