Test Example​

This guide will walk you through the fundamental steps to integrate Primus's zkTLS SDK and complete a basic data verification process through your application. You can learn about the integration process through this simple demo.

note

This example demonstrates how developers can create a frontend project and run Primus' proof verification system locally for testing purposes. We strongly recommend not using this method in a formal production environment. For guidance on configuring a production environment, please refer to the Production Example

Prerequisites​

Before you begin, ensure you have the following:

Implementation​

Here’s a basic example of how to use Primus’ zkTLS SDK from the frontend. Note that this implementation is intended for testing purposes only.

import { PrimusZKTLS } from "@primuslabs/zktls-js-sdk"

// Initialize parameters, the init function is recommended to be called when the page is initialized.
const primusZKTLS = new PrimusZKTLS();
const appId = "YOUR_APPID";
const appSecret= "YOUR_SECRET"; // Just for testing, appSecret cannot be written in the front-end code
const initAttestaionResult = await primusZKTLS.init(appId, appSecret);
console.log("primusProof initAttestaionResult=", initAttestaionResult);

export async function primusProof() {
    // Set TemplateID and user address.
    const attTemplateID = "YOUR_TEMPLATEID";
    const userAddress = "YOUR_USER_ADDRESS";
    // Generate attestation request.
    const request = primusZKTLS.generateRequestParams(attTemplateID, userAddress);

    // Transfer request object to string.
    const requestStr = request.toJsonString();
    // Sign request.
    const signedRequestStr = await primusZKTLS.sign(requestStr);

    // Start attestation process.
    const attestation = await primusZKTLS.startAttestation(signedRequestStr);
    console.log("attestation=", attestation);

    // Verify siganture.
    const verifyResult = await primusZKTLS.verifyAttestation(attestation)
    console.log("verifyResult=", verifyResult);

    if (verifyResult === true) {
        // Business logic checks, such as attestation content and timestamp checks
        // do your own business logic.
    } else {
        // If failed, define your own logic.
    }
}

Submit attestation on-chain (optional)​

To submit the verified data result (proof) to the blockchain, you’ll need to invoke the appropriate smart contract method. For detailed instructions, please refer to the onchain interactions.
