Interacting with Smart Contracts in WordPress: A Guide

As a developer, you’re likely no stranger to deploying smart contracts on the blockchain. However, once your contract is live, interacting with it from within your application can be a significant challenge. In this article, we’ll explore some of the best tools and ways to interact with a deployed smart contract from within a WordPress website.

1. Blockchain APIs

Blockchain platforms like Ethereum, Binance Smart Chain, and Polkadot offer APIs that allow developers to interact with their blockchain networks from external applications. These APIs typically require authentication and permission tokens to access your account data.

To use the API in WordPress, you can:

• Install a plugin like
  WP-Blockchain

  or
  Blockchain API (free) that provides an API interface for various blockchain platforms.

• Use the curl command-line tool from your operating system’s terminal to send HTTP requests to the blockchain API endpoint.

For example:

curl - X POST \

  

  -H 'Content-Type: application/json' \

  -d '{"data": "your_data"}'

2. Smart Contract Interface Libraries

Some smart contract platforms, such as OpenZeppelin and Solidity, provide libraries that allow developers to interact with their contracts from external applications.

WordPress has plugins like
Solidity-Wrapper

(free) that enable you to interface with deployed contracts using the Solidity language.

To use this plugin:

• Install and activate the plugin.

• Create a new solidity contract and deploy it on a testnet.

• Use the WordPress shortcode wp-blocks or wp-soldier to interact with your deployed contract:

$block_name = 'YourContractName';

$contract_address = '0xyour_contract_address';


$soldier_args = array(

    'contract' => $contract_address,

    'arguments' => array(array('data', "your_data")),

);

?>


    < input type= 'text' name='block-name' value="">

3. Web3.js and JavaScript

For more advanced use cases, you can use Web3.js to interact with your deployed contract using JavaScript.

WordPress has plugins like
WP-Web3-Js (free) that provide an interface for interacting with smart contracts from within WordPress.

To use this plugin:

• Install and activate the plugin.

• Create a new Solidity contract and deploy it on a testnet.

• Use web3.js to interact with your deployed contract:

const Web3 = require('web3');

const web3 = new Web3(new Web3.providers.HttpProvider('


const contractAddress = '0xyour_contract_address';


const instance = new web3.eth.Contract(contractAddress, 'YourContractName');


instance.methods.yourFunction().call()

  .then((result) => console.log(result)) .

  .catch((error) => console.error(error));

4. GraphQL

GraphQL is a query language for APIs that allows you to define queries and mutations in a single request.

WordPress is a free app that allows you to interface with smart contracts using GraphQL.

To use this plugin:

• Install and activate the plugin.

• Define your contract’s schema using GraphQL syntax:

“`graphql

type Contract {

data: String!
