How do I bulk upload 10,000 or large nft collection in opensea in 5 minutes using smart contract

When I first discovered about NFT marketplace Opensea and scared about how azuki , bored ape , world of womes bulk upload 10,000 nfts in the marketplace

Several questions strike my mind did they pay millions of dollars while uploading 10k nfts, how many days does it takes for them to upload their large collection, cost of uploading large all the nfts etc. All these questions are common for every beginner who just entered this new NFT space

So, In order to get the answer to this all questions, I researched a lot read articles saw youtube videos, asked for help from the developer community, etc

After all these hardships Finally, I got my answers for all the above questions also a very amazing way to bulk upload 10k NFTs in the opensea also in this way you can :

• Save your time and efforts ( you no need to sit in front of your pc / laptop for uploading 10k NFTs in the open sea )
• It is a very simple and fast way of uploading bulk NFTs
• It will save you lots of gas fees for uploading

ok, so let’s start learning and implementing it

Step 1)  Go to ERC721A github repository :

if you scroll down you will get a usage section where some solidity code is written, you just need to copy that code

Step 2) Go to Remix Ide :

Create a new File give a beautiful name and Paste the source code which you have copied from ERC721A github repository

Step 3) In the above image :

you can clearly see that at the end of the source code I have added 2 new line of code so you need to add that and remember you need to add the metadata CID of your nft collection in the last line of the source code

Step 4) Setting up smart contract :

Next , you need to deploy the smart-contract by selection injected WEB3 then select your smart contract and deploy to your blockchain network

• But remember you can deploy it in testnet before deploying to mainnet

• Choosing Injected web3 option

• Selecting my smart contract as remix has lots of custom contracts but we need to choose ours and click on that deploy button and after that pay the gas fees and your smart contract will deploy in your blockchain network

Step 5) Final steps :

Deployed contract then click on the mint button and add the amount of nfts you want to bulk mint in opensea let say I will mint 10k so I will write 10000 in the input section and click on the transact button after that I need to pay the gas fees for minting the NFTs and after that it will display 10k nfts in opensea

Try it by your own and comment below it is working for you or not and if you face any problem then let me know I will solve it , Also for better understanding I am pasteing a youtube video covering all the steps written above hope it will help you to understand in better way
