Swisstronik SDI Contracts

Overview

Contracts to interact witht the compliance module.

It's designed for managing issuer records and verifying user compliance based on various criteria. It leverages the OpenZeppelin library for secure contract upgradeability and ownership management. The contract interacts with the compliance module/bridge to verify user data against issuer records.

Features

• Issuer Management: Add, update, and remove issuer records securely.
• User Verification: Verify users based on compliance criteria such as AML (Anti-Money Laundering) checks and humanity verification.
• Data Retrieval: List issuer records and verification data for users.
• Upgradeability: Utilizes OpenZeppelin's upgradeable contracts for future improvements without losing state.

Integration

In your solidity repository, run npm i @swisstronik/sdi-contracts

pragma solidity ^0.8.24;

import {ISWTRProxy} from "@swisstronik/sdi-contracts/contracts/interfaces/ISWTRProxy.sol";

contract Sample {
    ISWTRProxy public swtrProxy;
    
    constructor(ISWTRProxy _swtrProxy) { swtrProxy = _swtrProxy; }

    function isUserVerified(
        address user,
        ISWTRProxy.VerificationType verificationType
    ) public view returns (bool) {
      return swtrProxy.isUserVerified(user, verificationType);
    }

}
