Approach: Integrating Lit Protocol with Sign Protocol's SDK

This section outlines the steps and approach I followed to integrate the Lit Protocol with the Sign Protocol SDK for gated access and encrypted attestations. The focus was on ensuring compatibility while enhancing functionality with Lit's encryption capabilities.

Key Steps in the Integration

  • Migration to TSC Builder
  • Replaced the Rollups builder in the sp-sdk with the native TypeScript (TSC) builder.
  • This change resolved compatibility issues between the sp-sdk and Lit Protocol SDK.
  • The migration ensures smoother builds and aligns with the evolving requirements of the SDK ecosystem.

Support for Gated Access

  • Added additional arguments in options like gated, accessControlConditions in create, get and revoke attestations
  • Currently, this feature is limited to on-chain attestations only, with plans for broader support in future iterations.

Handling Encrypted Attestations

  • When an attestation is marked as encrypted the base64 encrypted string and data hash are securely stored on-chain.
  • These encrypted values can only be decrypted using the access conditions specified at the time of creation.
  • The integration with Lit Protocol ensures robust encryption and access control, leveraging its advanced encryption capabilities.

Approach: Integrating Lit Protocol with Sign Protocol's SDK
This section outlines the steps and approach I followed to integrate the Lit Protocol with the Sign Protocol SDK for gated access and encrypted attestations. The focus was on ensuring compatibility while enhancing functionality with Lit's encryption capabilities.
Key Steps in the Integration
  • Migration to TSC Builder
  • Replaced the Rollups builder in the sp-sdk with the native TypeScript (TSC) builder.
  • This change resolved compatibility issues between the sp-sdk and Lit Protocol SDK.
  • The migration ensures smoother builds and aligns with the evolving requirements of the SDK ecosystem.
Support for Gated Access
  • Added additional arguments in options like gated, accessControlConditions in create, get and revoke attestations
  • Currently, this feature is limited to on-chain attestations only, with plans for broader support in future iterations.
Handling Encrypted Attestations
  • When an attestation is marked as encrypted the base64 encrypted string and data hash are securely stored on-chain.
  • These encrypted values can only be decrypted using the access conditions specified at the time of creation.
  • The integration with Lit Protocol ensures robust encryption and access control, leveraging its advanced encryption capabilities.

Instructions
Follow the steps below to clone the repository, set up the environment, and run the demo:
Clone the Repository
  1. Clone the repository to your local machine using the following command:
    git clone https://github.com/DaevMithran/SignxLit.git
  2. Navigate to the Demo Directory
    cd demo
  3. Install Dependencies
    npm i --save
  4. Add a Private Key
  • Create a .env file in the demo directory.
  • Add a 32-seed private key in the .env file as follows:
    PRIVATE_KEY=<your-32-seed-private-key>
  1. Build the Project
    npm run build
  2. Start the Demo
    npm start
