How Do I Mint Gas-Free NFTs On Opensea?

Ethereum is the essential blockchain in the world for NFTs. However, as many already know, the Ethereum experience has been a turn off lately owing to its overloaded network leading to a notoriously expensive gas fee.

Given Ethereum’s current shortcomings, OpenSea’s decided to integrate Polygon to make things less expensive, eventually leading to a cut off in gas fees.

Polygon is a blockchain that makes Ethereum tokens, such as NFTs, fast and cheap to transfer. 

Ethereum founder Vitalik Buterin just urged NFT projects to migrate their tokens to Polygon, having admitted to the poor scalability of the Ethereum network.

Switching between Polygon and Ethereum networks on OpenSea happens with a quick click of a button — a nice user-friendly touch that’s easy for beginners.

Opensea allows artists to group similar art with a feature called a collection. A collection houses a similar piece of art. As an artist, you should ensure orderliness to attract high-value collectors; keeping your artwork scattered makes it challenging to pick.

Make sure you feel up to these fields.

1. Logo Image – This field lets you upload a logo to identify your art.

2. Featured Image – This field lets you upload a featured image to identify your art.

3. Banner Image – This Field enables you to upload a banner image to identify your art

4. Name – This field allows you to enter the name of your collection, make sure this is a generic name because when you go viral, that will be the unique identifier.

5. URL – This field allows you to enter the collection’s website. You might need to show a website to justify your project; it convinces the collector to collect your art.

6. Description- This field allows you to enter a description of your collection.

7. Category- This enables you to categorise your collection on the Opensea platform. There are over 12 categories

9. Royalties – Royalties are the amount you get back when a collector resells your art. This allows you to

10. Blockchain – This section allows you to choose the kind of blockchain to host your NFT. It comes with two options which are Ethereum and Polygon.

Using Ethereum comes with a vast gas fee, while Polygon is gas-free.

If you have the funds to spend on minting with the Ethereum gas fee.

11. Payment Tokens – This section allows you to choose your prefered payment tokens.

Opensea supports more than one token. In addition, it includes additional support for tickets like DAI, USDC and many others. These tokens are part of the Polygon and Eth network.

One step before the final is to begin uploading unique art to the collections you created.
Make sure that you arrange your arts in a particular order of collection. For example, the following fields need to be filled up in a specific order.

7. Levels – This field allows you to add metadata to your art called Levels. If you have no valid option, it can be left blank. However, I recommend you leave it blank.

8. Stats – The same option for this field is also an option to add stats metadata. If you have no valid option, it can be left blank. But, again, I recommend you leave it blank.

10. Explicit & Sensitive Content – You should indicate whether your art contains explicit or sensitive content.

11. Supply – This field allows you to set your token’s total supply on the entire blockchain. This field is in digits, and you should be careful how you put it.

For example, I can create an NFT art and set the total supply on the blockchain to be 1,000,000, meaning that the complete purchasable copies are One million.

12. Blockchain – This field allows you to choose your prefered blockchain to host your NFT; remember that Ethereum is not free, but Polygon is free whichever way.

13. Freeze Metadata – Metadata summarises basic information about data, making tracking and working with specific data more accessible.

You will be presented with this screen as soon as you click the SELL button just after you created your art.

1. Quantity – This Field allows you to list the total amount of NFT that you want to sell out; remember you minted 1 million copies when you recorded your art; this section allows you to set the target number you intend to sell, also make sure you keep some for yourself.

1. Rarible.

How To Mint Gas-Free NFTs On Opensea

Rarible is an NFT (non-fungible token) that allows users to create, buy and sell NFT without needing to code; it also comes secured with blockchain technology.

Rarible was founded by Alex Salnikov and Alexei Falin back in early 2020 back in Russia.

Rarible also acts like an online marketplace where creators can “mint” NFTs and collectors can buy them.

This digital marketplace allows creators to sell everything from their favourite NFTs in the form of audios, music and images to artwork featuring Tupac.

Rarible has a considerably more ambitious vision than merely becoming a platform for securing art and digital collectables using blockchain.

It also comes with Rarible’s ERC-20 governance token, which has continued to attract many investors recently.

I recommend each investor check out Binance. The RARI token is the native token to the Rarible platform, and it Launched in July 2020 as the first governance token in the NFT sBeforeupply of 25,000,000 half; what should you look for? Which is reserved for buyers and sellers.

Rarible enables anyone to mint NFTs at no cost, thereby enabling end collectors to pay for minting once collected artwork on the platform.

Another NFT marketplace everyone should check out is Foundation. app. It makes the auction of NFTs seamless with the help of its intuitive platform. 

Whenever an NFT is traded on the Foundation platform, the artist makes 10% on the secondary transaction carried out. 

This means that when any collector resells an artist’s work, the artist receives 10% of the amount made in sales.

You should also know that Foundation charges 15% as the service fees. The service fees charged by Foundation are the highest, and we do not know any other platform that captures more elevated than 15%. 

Platform fees do not include the Ethereum gas fees, which the Ethereum network requires to process the transactions. 

Foundation. The app makes it easy to accept payments with several options such as deposits, debit or credit cards. A few of them also accept PayPal deposits and withdrawals; also, make sure you hold a tiny ETH so that you can interact with others on this marketplace.

Are you going hardcore into NFTs, then Mintable is one platform not to overlook?

The platform stands out as an excellent entry platform into the NFT space. It is not only easy to use but perfect for beginners.

Also, make sure you hold some ETH to get started with because you will need it to buy and mint NFTs on Mintable. 



The NFT world is changing at speedway more than lightning itself. Non-fungible tokens (NFTs) have changed how we think about digital assets and their sales and ownership.

NFTs symbolise the future for many artists and collectors, allowing financial freedom for creativity and investment potential.

OpenSea, unlike other platforms, does not impose a fee to mint NFTs; you are at liberty to choose a blockchain where you want your NFT to live; Ethereum might be expensive because of its gas fee, while Polygon serves as an alternative because it allows you mint at no cost.

With the OpenSea platform experiencing tremendous success since it launched, the business model looks to be feasible and is an excellent option for young NFT producers to get started.
