Ever wondered how people manage to upload a large collection to Opensea? We tell you how.
First of all it’s important to understand the two different ways people put collections on Opensea. There is the lazy mint way, and smart contract method.
Lazy Minting on Opensea
This is when you upload an image to Opensea using the Opensea website. You will notice I used the word image rather than NFT. People who are new to NFTs assume the piece of art becomes an NFT as soon as its uploaded to Opensea, but it is not. Did you know it only becomes an NFT when someone buys your art? You can only upload one image at a time using this method, which has to go through a captcha check. This prevents people from uploading massive collections. Many people claim they can overcome the captcha check using bots or python programs. However, this can require a lot of effort which is not guaranteed to work.
Smart Contract Method
The best way is to create a smart contract (see our guide here). Then mint as many tokens (NFTs) as you like via that contract. A smart contract can be deployed from an online coding editor software called Remix IDE. Once the smart contract has been created and tested, it is then deployed to the Main Testnet network, and sent to your wallet address. The cool thing about Opensea is that it displays this NFT data in your wallet, so it can be viewed on the Opensea website. This means that visitors can view your collection and buy NFTs from it.
The Bottom Line
Now you know how to upload a large collection to Opensea the professional way. Smart contract creation is always the best way to go in the NFT world. This is because it ensures the contract unique to your collection, and you can set precise rules for how your collection will be transacted on the Ethereum blockchain.
