Let’s understand more about OpenSea before we dive into our topics.

OpenSea marketplace

The OpenSea marketplace is similar to another platform which has 𝚜electing, organizing, and looking after the items in digital arts. It is the oldest and most widely appreciated online marketplace with excessive pride and self-satisfaction.

The OpenSea marketplace runs with the Ethereum smart contracts and records transactions on the blockchain. Here, the users do not need to sign up before using the marketplace.

The OpenSea is free for minting, buying, and selling NFTs. However, it charges for clever and indirect methods to achieve service fees, usually between 2.5%-3%, when you sell your crypto art on its marketplace.

Advantages of using OpenSea

  • The OpenSea is secured by smart contracts, Making fraudulent transactions impossible.
  • It charges the lowest commission fees for buying and selling NFT.
  • Here you can quickly start your NFT collection without knowing blockchain or coding.
  • The high-profile digital artist mints multi-edition of his artwork.

 Disadvantages of using OpenSea

  • The Open-sea allows royalties up to 10% for artists.
  • You may note that secondary sellers can keep more profit for themselves.
  • The majority of crypto arts and the multi-edition are unoriginal.
  • The selling point for low-profile artists looking to increase profit margins in the OpenSea.


How to Mint Multiple NFT on OpenSea at Once

When you are trying to mint say 10,000 NFTs at once then you will find it difficult to do it manually. Also, OpenSea does not like when you bulk upload NFTs as most of the time the artwork might be automated. And as OpenSea has mentioned on their Twitter handle bulk upload leads to misuse of their creator tools.

OpenSea is putting effort to stop people from bulk uploading by giving ReCaptcha for verification. Around 27 Jan. 2022, OpenSea had limited the number of items in a collection and the number of collections a creator can open. Previously for some time, OpenSea only supported the creation of up to 5 collections and 50 items per collection. OpenSea will throw you this error whenever you try to exceed the limit – “You have reached the max number of items in this collection OpenSea”.

But as OpenSea received a huge backlash from its community for imposing the limit, it reversed its decision the next day. There was a heated debate on the same topic on this Reddit thread, if interested check it out.

The point that I tried to present is that OpenSea is trying to actively fight off plagiarized works, fake collections, and spam. And in that process, OpenSea is trying to make bulk minting with automation impossible.


How people used Mint Multiple NFTs with Automation

As I had done my research I would like to share it with you about the earlier tactics. The common tactic that people took to mint 10,000 or more NFT is automation.

Although I have discussed this tactic it’s only for your information purpose.

First of all, people generated an insane number of images for their NFT collections by using Hash Lips Git Code. They created like 4-5 layers for the image and each layer had say 10-15 variations. In the code editor people could set the weight or frequency for the variation to occur, making some images unique and others common. Then they ran the code on some code editor like Visual Studio Code and produced like 10,000 or more NFTs in some minutes.

Now comes the uploading part, for automating the upload there exists a mouse activity recorder like Mini Mouse Macro. People used to record their single NFT upload activity and then set a repeat loop for the other 9,999.

People also found a solution by using Selenium which is an Open Source project that contains tools and libraries for web browser automation.

This was the way it was done.

Now it has become difficult to work with the same tactic for bulk minting with automated tools. Read More as we dive into the solution for the same problem.


How can you mint Multiple Multiple NFT with Third Party

The automation technology has been becoming redundant because of the ReCaptcha validation. However, some external websites help you to mint multiple NFTs on OpenSea.

You can bulk mint NFT with the help of Nifty Mints. However, Nifty Mints is a paid solution where you can only mint 30 NFT for free, and then for each NFT to mint, you will require to pay 0.2 USD. 

The way the Nifty Mint works is that it creates a smart contract for each of your collections and assigns you as the owner of that contract, unlike the minting contract on OpenSea which is owned by OpenSea.

Additionally, whenever you mint your NFTs through Nifty Mints it directly goes on the polygon chain. That means assets and the metadata both go to decentralized file storage which is IPFS

Whenever you lazy mint on OpenSea the metadata does not go onto the blockchain, which means your images might be stored on a centralized server like GCP and not on decentralized servers until you freeze the metadata which will again require Gas fees.

If you are trying to bulk mint NFT with Nifty Mints, you can watch this tutorial by Refactored.

Also, there is one other NFT utility tool that can help you to bulk list NFT on OpenSea, but for that, you will require to have NFT in your wallet to bulk list on OpenSea.

We are still looking for free solutions to the bulk minting problem. So, If you have found the solution then do mention it in the comments, we will be more than happy to update this article with a free solution.
