Verifying Wallets

The Enjin Platform offers a Wallet verifying process that you can use to verify the authenticity of a user's blockchain address.

tip

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

What you'll need:

• An Enjin Platform Account.

By using wallet verification, you can receive the user's wallet address with 100% certainty that this wallet is owned by the user.

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

fetch('https://platform.canary.enjin.io/graphql', {
  method: 'POST',
  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
          verificationId #Save this for next step
        }
      }
    `
  }),
})
.then(response => response.json())
.then(data => console.log(data));

Node.js

const axios = require('axios');

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

      }
    }
  `
}, {
  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",
      "verificationId": "0x78afab1ad1294c1eef827e6ac5352bb95f6af5ba6e2699ddd927b006d7d9436c"
    }
  }
}

This will generate a linking code from the Enjin Platform, which the user can scan with their Enjin Wallet. The wallet will then send their address to the Enjin Platform, allowing you to retrieve it

Step 2: Verify Account

Once the user has scanned the QR code using the Enjin Wallet, 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
