Verifying Wallets

Before you can interact with a user's blockchain items or associate their in-app identity with their blockchain address, you need a reliable way to confirm they own the wallet they provide. The Enjin Platform's wallet verification process provides a secure method to achieve this.

By verifying a user's wallet, you gain certainty that the public wallet address shared genuinely belongs to them. This verified link is essential for securely accessing their blockchain inventory, delivering items, or granting ownership-based perks within your application.

The verification process typically involves:

1. Your application requests a unique verification code and QR code from the Enjin API.
2. The user scans the QR code with their Enjin Wallet App.
3. The Enjin Wallet App confirms ownership and securely provides the wallet address to the Enjin Platform.
4. Your application retrieves the verified address from the Platform.

Once verified, you can confidently associate this blockchain address with the user's account in your system, enabling seamless blockchain interactions.

tip

If you need to send requests to user wallets, use WalletConnect instead.

What you'll need:

• An Enjin Platform Account.

Verify Wallet with the Enjin API

Step 1. Initiate an Account Request

To initiate the account request process, run the following query:

Query:

GraphQL

query RequestAccount{
  RequestAccount{
    qrCode #Returns a QR code for your user to scan
    verificationId #Save this for next step
  }
}

cURL

curl --location 'https://platform.canary.enjin.io/graphql' \
-H 'Content-Type: application/json' \
-H 'Authorization: enjin_api_key' \
-d '{"query":"query RequestAccount {\r\n  RequestAccount {\r\n    qrCode #Returns a QR code for your user to scan\r\n    verificationId #Save this for next step\r\n  }\r\n}\r\n","variables":{}}'

c# SDK

using System.Text.Json;
using Enjin.Platform.Sdk;

// Setup the query
var requestAccount = new RequestAccount();

// Define and assign the return data fragment to the query
var accountRequestFragment = new AccountRequestFragment()
    .WithQrCode()
    .WithVerificationId();

requestAccount.Fragment(accountRequestFragment);

// Create and auth a client to send the request to the platform
var client = PlatformClient.Builder()
    .SetBaseAddress("https://platform.canary.enjin.io")
    .Build();
client.Auth("Your_Platform_Token_Here");

// Send the request and write the output to the console.
// Only the fields that were requested in the fragment will be filled in,
// other fields which weren't requested in the fragment will be set to null.
var response = await client.SendRequestAccount(requestAccount);
Console.WriteLine(JsonSerializer.Serialize(response.Result.Data));

C++ SDK

#include "EnjinPlatformSdk/CoreQueries.hpp"
#include <iostream>

using namespace enjin::platform::sdk;
using namespace std;

int main() {

    // Set up the query
    RequestAccount requestAccount = RequestAccount();

    // Define and assign the return data fragments to the query
    AccountRequestFragment accountRequestFragment = AccountRequestFragment()
            .WithQrCode()
            .WithVerificationId();

    requestAccount.SetFragment(make_shared<AccountRequestFragment>(accountRequestFragment));

    // Create and auth a client to send the request to the platform
    unique_ptr<PlatformClient> client = PlatformClient::Builder()
            .SetBaseAddress("https://platform.canary.enjin.io")
            .Build();
    client->Auth("Your_Platform_Token_Here");

    // Send the request then get the response and write the output to the console.
    // Only the fields that were requested in the fragment will be filled in,
    // other fields which weren't requested in the fragment will be set to null.
    future<PlatformResponsePtr<GraphQlResponse<AccountRequest>>> futureResponse = SendRequestAccount(*client, requestAccount);

    // Get the platform response holding the HTTP data
    PlatformResponsePtr<GraphQlResponse<AccountRequest>> response = futureResponse.get();

    // Get the result, a GraphQL response, holding the GraphQL data
    const optional<GraphQlResponse<AccountRequest>>& gqlResult = response->GetResult();

    // Write the result data to the console
    if (gqlResult.has_value() && gqlResult->IsSuccess())
    {
        const optional<AccountRequest>& getAccountRequestResult = gqlResult->GetData()->GetResult();

        std::cout << getAccountRequestResult->GetVerificationId().value() << std::endl;
    }

    // Write any error messages to the console
    if (gqlResult.has_value() && gqlResult->HasErrors())
    {
        const optional<vector<GraphQlError>>& errors = gqlResult->GetErrors();

        for (const GraphQlError& error : errors.value()) {
            std::cout << error.GetMessage().value() << std::endl;
        }
    }

    client.reset();

    return 0;
}

Javascript

  headers: {'Content-Type': 'application/json','Authorization': 'Your_Platform_Token_Here'},
  body: JSON.stringify({
    query: `
      query RequestAccount{
        RequestAccount{
          qrCode #Returns a QR code for your user to scan

        }
      }
    `
  }),
})
.then(response => response.json())
.then(data => console.log(data));

Node.js

const axios = require('axios');

axios.post('https://platform.canary.enjin.io/graphql', {
  query: `

      }
    }
  `
}, {
  headers: {'Content-Type': 'application/json','Authorization': 'Your_Platform_Token_Here'}
})
.then(response => console.log(response.data))
.catch(error => console.error(error));

Python

import requests

query = `'''
query RequestAccount{
  RequestAccount{
    qrCode #Returns a QR code for your user to scan
    verificationId #Save this for next step
  }
}
'''`

response = requests.post('https://platform.canary.enjin.io/graphql',
  json={'query': query},
  headers={'Content-Type': 'application/json', 'Authorization': 'Your_Platform_Token_Here'}
)
print(response.json())

Response:

{
  "data": {
    "RequestAccount": {
      "qrCode": "https://platform.canary.enjin.io/qr?s=512&f=png&d=https://platform.canary.enjin.io/proof/MHg3OGFmYWIxYWQxMjk0YzFlZWY4MjdlNmFjNTM1MmJiOTVmNmFmNWJhNmUyNjk5ZGRkOTI3YjAwNmQ3ZDk0MzZjO2Vwc3I6QTIwMTBBSzlM",

    }
  }
}

This will return a link to a QR Code for you to display to your user, and a unique verification id to track the request. In your application, you'll display this QR code to your user and instruct them to scan it with their Enjin Wallet App

.

Step 2: Verify Account

To confirm that the user scanned the QR code and approved the request, you can retrieve the account using two methods.

Option A: GetWallet

Using GetWallet and passing the verificationId from step 1, you will be able to get any information related to his wallet if the verification process succeeded.

Query:

GraphQL

query GetVerifiedWallet{
  GetWallet(verificationId: "0x78afab1ad1294c1eef827e6ac5352bb95f6af5ba6e2699ddd927b006d7d9436c"){ #Set the verificationId from the RequestAccount response
    account{

    balances{
      free
    }
