Restricting Access to a WordPress Website

Oct 13, 2025 by wbrum.org 95 views

Introduction

In the world of web3 and blockchain technology, securing access to websites and applications is becoming increasingly important. One way to achieve this is by restricting access to a website based on the contents of a MetaMask wallet. In this article, we will explore how to achieve this using a WordPress website as an example.

What is MetaMask?

MetaMask is a popular browser extension and mobile app that allows users to interact with the Ethereum blockchain. It provides a secure way to store, send, and receive cryptocurrencies, as well as interact with decentralized applications (dApps). MetaMask wallets are unique in that they can be used to store a wide range of digital assets, including NFTs (non-fungible tokens).

The BAYC Bathroom Example

The BAYC (Bored Ape Yacht Club) bathroom is a popular example of a website that restricts access based on the contents of a MetaMask wallet. When users try to log in, they are redirected to a "bathroom" page that displays a unique message based on the contents of their wallet. This message is determined by the wallet's balance, the presence of specific NFTs, or other factors.

Restricting Access to a WordPress Website

To restrict access to a WordPress website based on the contents of a MetaMask wallet, we will need to use a combination of WordPress plugins and custom code. Here's a step-by-step guide to achieve this:

Step 1: Install the Required Plugins

To restrict access to a WordPress website based on the contents of a MetaMask wallet, we will need to install the following plugins:

MetaMask Wallet Checker: This plugin allows us to check the contents of a MetaMask wallet and retrieve specific information.
Conditional Logic: This plugin allows us to create conditional statements based on the contents of the MetaMask wallet.

Step 2: Create a Custom Function to Check the MetaMask Wallet

To check the contents of a MetaMask wallet, we will need to create a custom function that uses the MetaMask Wallet Checker plugin. Here's an example of how to create this function:

function check_meta_mask_wallet() {
  // Get the MetaMask wallet address from the user's session
  $wallet_address = get_user_meta(get_current_user_id(), 'meta_mask_wallet_address', true);

  // Check if the wallet address is valid
  if (!$wallet_address) {
    return false;
  }

  // Get the MetaMask wallet contents using the MetaMask Wallet Checker plugin
  $wallet_contents = get_meta_mask_wallet_contents($wallet_address);

  // Check if the wallet contents meet the required conditions
  if (!check_conditions($wallet_contents)) {
    return false;
  }

  // If the wallet contents meet the required conditions, return true
  return true;
}

Step 3: Create a Conditional Statement to Restrict Access

To restrict access to the website based on the contents of the MetaMask wallet, we will need to create a conditional statement using the Conditional Logic plugin. Here's an example of how to create this statement:

if (!check_meta_mask_wallet()) {
  // Redirect the user to a restricted page
  wp_redirect(get_permalink(123));
  exit;
}

Step 4: Add the Conditional Statement to the Website

To add the conditional statement to the website, we will need to add it to the website's theme or a custom plugin. Here's an example of how to add it to the website's theme:

function restricted_access() {
  // Check if the user is logged in
  if (is_user_logged_in()) {
    // Check if the user's MetaMask wallet meets the required conditions
    if (!check_meta_mask_wallet()) {
      // Redirect the user to a restricted page
      wp_redirect(get_permalink(123));
      exit;
    }
  }
}

add_action('wp_head', 'restricted_access');

Conclusion

Restricting access to a website based on the contents of a MetaMask wallet is a complex task that requires a combination of WordPress plugins and custom code. By following the steps outlined in this article, you can create a website that restricts access based on the contents of a MetaMask wallet. This can be useful for a wide range of applications, including membership sites, exclusive communities, and more.

Future Development

In the future, we can expect to see more advanced features and plugins that allow us to restrict access to websites based on the contents of a MetaMask wallet. Some potential features that could be developed include:

Multi-condition checking: This would allow us to check multiple conditions in the MetaMask wallet, such as the presence of specific NFTs or the balance of a specific cryptocurrency.
Customizable messages: This would allow us to display custom messages to users based on the contents of their MetaMask wallet.
Integration with other blockchain platforms: This would allow us to restrict access to websites based on the contents of wallets on other blockchain platforms, such as Binance Smart Chain or Polkadot.
