Create Addresses

Introduction

In this tutorial, we will cover how to create addresses for Polygon, Binance Smart Chain, Ethereum, and Tron using Chaingateway. We will provide examples in various programming languages, including Shell (cURL), PHP (Guzzle), Python (Requests), and JavaScript (Axios).

For obtaining an API key and learning about authorization, please refer to the Quickstart section of the Chaingateway documentation.

Creating Addresses

When creating a new address for an EVM based blockchain, we need to create a keystore. This is a security mechanism to keep your information safe. The keystore will be encrypted with a password. With this mechanism, you do not need to send your private key within your transaction payload but only your password. A person that has only the keystore file or only the password cannot access the address.

To create the address, send a request to the Chaingateway API.

Parameters

• password: This is a user-defined password for the new address. It is used to secure the address and will be required for performing transactions with this address. It is essential to store this password securely as Chaingateway does not store or have access to it. If the password is lost, the address cannot be accessed.

Password-less wallets creation

If you do not provide a password, we will create the wallet and send you the private key directly in the response. This approach should only be used for single-use addresses because it is an unsafe approach to provide the privatekey in every single transaction request

Authorization Header

Replace YOUR_API_TOKEN with your actual API token.

Example Code (Password Protected Wallet)

Usage for other Blockhains and networks

This code example is using /ethereum in the route as an example. feel free to just replace it with /bsc or /polygon for creating it on other networks.

you can also replace https://api.chaingateway.io with https://testnet.chaingateway.io to switch to the testnet networks.

curl

curl --request POST\
    --url https://api.chaingateway.io/v2/ethereum/addresses\
    --header 'Accept: application/json'\
    --header 'content-type: application/json'\
    --header 'Authorization: YOUR_API_TOKEN'\
    --data '{"password":"test123"}'

python

import requests

url = "https://api.chaingateway.io/v2/ethereum/addresses"
payload = {"password": "test123"}
headers = {
        'Accept': 'application/json',
        'content-type': 'application/json',
        'Authorization': 'YOUR_API_TOKEN'
}

response = requests.post(url, json=payload, headers=headers)
print(response.json())

javascript

const axios = require('axios');

const url = 'https://api.chaingateway.io/v2/ethereum/addresses';
const payload = { password: 'test123' };
const headers = {
    'Accept': 'application/json',
    'content-type': 'application/json',
    'Authorization': 'YOUR_API_TOKEN'
};

axios.post(url, payload, { headers })
    .then(response => {
        console.log(response.data);
    })
    .catch(error => {
        console.error(error);
    });

php

<?php
require 'vendor/autoload.php';

use GuzzleHttp\Client;

$client = new Client();
$response = $client->post('https://api.chaingateway.io/v2/ethereum/addresses', [
        'headers' => [
                'Accept' => 'application/json',
                'content-type' => 'application/json',
                'Authorization' => 'YOUR_API_TOKEN',
        ],
        'json' => ['password' => 'test123']
]);

echo $response->getBody();
?>

Response

{
    "status": 201,
    "ok": true,
    "message": "Address created",
    "data": {
        "adderess": "0x7d3bC832A0860fD882FF4C2359e10268f4E5CCf8"
    }
}

Example Code (Non Protected Wallet)

curl

curl --request POST\
  --url https://api.chaingateway.io/v2/tron/addresses\
  --header 'Accept: application/json'\
  --header 'content-type: application/json'\
  --header 'Authorization: YOUR_API_TOKEN'

python

import requests

url = "https://api.chaingateway.io/v2/tron/addresses"
headers = {
    'Accept': 'application/json',
    'content-type': 'application/json',
    'Authorization': 'YOUR_API_TOKEN'
}

response = requests.post(url, headers=headers)
print(response.json())

javascript

const axios = require('axios');

const url = 'https://api.chaingateway.io/v2/tron/addresses';
const headers = {
  'Accept': 'application/json',
  'content-type': 'application/json',
  'Authorization': 'YOUR_API_TOKEN'
};

axios.post(url, {}, { headers })
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

php

<?php
require 'vendor/autoload.php';

use GuzzleHttp\Client;

$client = new Client();
$response = $client->post('https://api.chaingateway.io/v2/tron/addresses', [
    'headers' => [
        'Accept' => 'application/json',
        'content-type' => 'application/json',
        'Authorization' => 'YOUR_API_TOKEN',
    ]
]);

echo $response->getBody();
?>

The response should look like this:

{
    "status": 201,
    "ok": true,
    "message": "Address created",
    "data": {
      "privateKey": "59f1c6200e01a2ca9471411f10198bfa63678d0e87cc2ca30f9c4a68dee78edc",
      "publicKey": "040fe6e677442c36f7fdd5535ba3ff1cef0110d78363420f7e24b65298990e3467aed68b9a67e1396d84753db25b32a2fa3e1fc0a673f01638e9bcfab2d8f4ceb5",
      "hexAddress": "41a56a6505ffbee78eb916dd44f4846874deddaebd",
      "address": "TR3qx91smURF3R455V1ubqtoUsZbgqikfg"
    }
}

You should store the privateKey and address on a secure place in your app

Important Information

For creating transactions, users need to provide the password of the address or the private key . Chaingateway does not store these sensitive pieces of information. Therefore, users must store them in a safe place. If these are lost, Chaingateway cannot assist in recovery as it does not have access to this information.

For obtaining an API key and learning about authorization, please refer to the Getting Started section of the Chaingateway documentation.
