Turning My 2021 Hashnode Tech Awards into NFTS - A walkthrough of how I did it

Merry Christmas from unclebigbay

So, After reading How To Mint an NFT - A Step-by-Step Guide To Creating Your First NFT by @Favor Onuoha, I decided to Mint my Hashnode award badges as my first NFT and I will be showing you how I did it.

I don't know if that's actually a good idea, but who cares, that's what I feel like minting.

Minting simply means to create something new on the blockchain, so in this article, you will experience how I created my first ever NFT on the blockchain.

Let's get started.

I will be making use of metamask and opensea

What is Metamask


In case you are hearing about MetaMask for the first time, MetaMask is basically a cryptocurrency wallet holder that allows you to interact with your Ethereum blockchain wallet account and can be used to connect to other blockchain applications.

Meta mask is available for iOS/Android devices and browser extensions, click here to get yours up and running.

Keep your security phrase and password safe like your life depends on it, there's no reset phrase (password) like web2.

What is OpenSea

OpenSea is an online marketplace for non-fungible tokens (NFTs). It was founded by Devin Finzer and Alex Atallah in New York on December 20, 2017.

OpenSea has been around for a very long time, thanks to the Web3 and NFTs popularity explosion, we get to know about it now.

It is where buying and selling of NFTs take place, this is the Alibaba of web3, you can upload your images, music, documents, and any other thing you wish to mint on the blockchain.

Super happy to be minting my badges there, maybe someone will actually buy them, but I am not selling ðŸĪŠ

Setting up OpenSea Account

I head to and click on the create button.


There are several wallet options to connect with, but MetaMask is the most popular and that's what I already installed.


The MetaMask browser extension pops up immediately after selecting the MetaMask provider option.

Click on the Next button.


Now you can be authenticated on the OpenSea marketplace, hit the connect button.


Sometimes you will see the sign button instead.


And that's it, I'm in, we're in the OpenSea market.


This is my OpenSea dashboard.


But I'm unclebigbay and not unnamed, it makes sense because my blockchain wallet doesn't carry a username in my profile object for OpenSea to retrieve from, web3 only cares about my wallet address.


Hover on the user profile avatar on the navbar and select the setting link to update your profile on OpenSea.


Fill in your profile details and hit the save button.


Profile updated.


Minting My Badges

The business of the day, which is to mint my hashnode badges, you can check out the awards on LinkedIn if you haven't seen them yet.

Create NFT

Click on the create navigation link on the navbar.


NFT profile

The two required detail of the new NFT you want to mint is the document you want to upload, check the supported document first, and the name of the NFT.



I will be providing an external link to redirect to my hashnode badge page and a short description of the awards.



I will be skipping the rest of the forms since I won't be selling my award badges ðŸĪŠ.

Click on the create button to submit the NFT.

Done and Dusted

Congratulations to me and you, we just successfully minted my very own first NFT together.


You can view my Hashnode award NFT badges HERE on OpenSea Marketplace.


Minting your awards, documents, or any asset that you own as demonstrated in this walkthrough article guarantees ownership of a unique digital asset. You can mint-supported digital assets such as JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, GLTF, with a max size of 100 MB on OpenSea.

Sounds cool, right? You can go ahead and mint yours using the step-by-step guide in this article.


I will be minting one of my articles very soon.

Wow, what a journey, I am glad you made it to the end of this article, if you enjoyed and learned something new from this article, I will like to connect with you.

Let's connect on

See you in the next article. Bye Bye 🙋‍♂ïļ
