Purchasing Mars4 NFTs via WalletConnect and Metamask - A How-To Guide

Purchasing Mars4 NFTs is easy to learn and simple to do via your own browser wallet. Mars4 supports two different protocols for NFT purchases: WalletConnect and Metamask.

1. WalletConnect: What is it?

WalletConnect is a widely supported web3 protocol to connect blockchain wallets with decentralized apps. It is able to be used via web browsers, android and iOS and supports a large variety of mobile wallets. 

To make use of the Wallet Connect protocol, you simply need to install and make use of any one of the supported mobile wallets as found here.

Using WalletConnect

Step 1: Click on ‘Connect Wallet’ to connect your Wallet

IMPORTANT! Always use your personal wallet for NFTs!


Step 2: Using one of the mobile wallets that are compatible with WalletConnect, open their app, scan the QR code of the Mars4 NFT sales page, and click ‘Connect’ in your wallet.

2. Metamask: What is it?

MetaMask is a software cryptocurrency wallet that works in conjunction with the Ethereum blockchain. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications.

Using Metamask

Making use of Metamask requires a Metamask account. In addition to this, you will need the Metamask extension to make the purchase (Chrome, Firefox, or Edge). The Metamask App allows you to view the NFTs held in your wallet, but is optional and works with Android and iOS.

Installing Metamask

Install the extension in your preferred web browser (Chrome, Firefox, or Edge). Once installation is complete, an icon in the shape of a fox will appear in the top right-hand corner of your browser or under your installed extensions.

Creating a Metamask account

To create a Metamask account, follow the sign up instructions as provided by Metamask. Remember to save your backup keys!


Once you have signed up, you should be able to see your Metamask wallet as seen in the example below.

Adding funds to your Metamask account

To make a purchase via Metamask, you will need to add funds to the Metamask wallet using any method you prefer (such as from an exchange directly or from another wallet). Metamask has the following guide to help walk you through the process.


NOTE: If purchasing Mars4 NFTs with USDT or USDC, make sure to have at least a minimal amount of ETH in your Metamask to cover the ERC20 transaction fees!

3. Purchasing your Mars4 NFTs

Once you have either a funded Metamask account or a mobile wallet supported by WalletConnect, you can now head to our NFT sales page. On the sales page, you can browse the available NFTs and purchase the quantity you desire with your currency of choice. The available currencies can be found in the dropdown menu.

If you have not yet connected a wallet, you will be prompted to do so via either of the two options. 

Purchases through Metamask are automatically prepared and will cause a new window to pop up. An example is prepared below.

All that is left to do is click ‘confirm’ and if payment is successful, the NFT minting process takes place automatically and will complete within 15 minutes of the transaction.

4. Finding your NFTs

NFTs are minted within 15 minutes of your purchase and will appear on Etherscan at the same time.

To see when your NFT arrives, you can click on ‘view transaction’ or visit https://etherscan.io/ and paste your Metamask wallet address into the search bar.

You can additionally view your NFTs via your Metamask account.

Purchasing Mars4 NFTs directly

The alternative to using Metamask is to make your NFT purchase through direct transfer to the Mars4 wallet. To do so, click on ‘direct transfer to Mars4 wallet’ instead of choosing the other payment options.

Copy the Mars4 wallet address or scan the QR code and make payment to this address. You should transfer the exact amount of USDT, USDC or ETH which will be displayed on the checkout panel.



Do Not pay from an exchange wallet directly! The NFT will be minted to the payment address and you will not have access to it.


If the payment is successful, the NFT minting process starts automatically. Usually, purchased NFTs show up on EtherScan in no less than 15 minutes.
