Glad you found it helpful. Good luck and happy building!

Super useful thanks 🎉

@ninjanick5769 Год назад

This video needed to at least be an hour, you rushed the entire process.Coming up with generative art with IPFS support and deploying your own Smart Contract needs you to be more detailed about it than a 21 min crash course tutotial Or maybe your method is quicker,I dunno

@QuickNode Год назад

You're right, that's a huge topic that deserves much more coverage. More will be coming, for sure.

IPFS nice to meet you I write you from Czech Republic why I can not go into page - IPFS there is some countries when can not working is there some addresses which works only in Czech Republic or Austria thank you!

Any input on how to setup the mint process for a buyer to get a random token ID?

@QuickNode Год назад

For that, you need to add a function to generate random IDs. You can do it by using a hash function, such as SHA-256, on a combination of random input parameters, such as the block timestamp and the buyer's address. Then, in a mint function, take the buyer's address as a parameter, generate a random token ID using the previous step, and mint the new NFT with that token ID.

@@QuickNode thanks so much, I can't wait to go through all your video and learn all this stuff. Are you affiliated with any certificate programs or anything like that?

@Oliver-wi9mt Год назад

Hello One question for you, If using your methods to deploy the NFT, Would i have to do the process of uploading the jpeg 10,000 times if i want to mint 10,000?

@hayyt 6 месяцев назад

I've done all the sequences but somehow transaction beeing confirmed after that I cant see the images on testnet opensea. I've tried a lot but couldn't be succesful.

@dayansflores611 4 месяца назад

hello using these smart contracts can you Edit Drop Settings in opensea studio to schedule delivery and presale?

@PapiWilson_ Год назад

Hey, amazing video. Had a couple questions though. Is there any way i can modify the metadata for the NFTs after it is minted? Also, if I wanted to have for example multiple collections, lets say for example one for sharks, one for clown fish, etc. can I use the same contract or do i have to create new ones?

@AntiMatrixGlobal Год назад

After uploading the metadata json file in Deploy, my collection in opensea will be in the form of a photo icon. It seems that the files could not be loaded. I have edited the cid of the photos in Jason's file many times in different ways. But I managed to fix them only once, but it doesn't work anymore.

i dont know about coding, how can i make my ERC721 contract for selling my NFT, kindly help me out

@crazycuts6891 Год назад

Even though I don't have any idea of the smart contract lingo, nice tutorial. I'm a complete layman in this smart contracts realm, but I'm also an admirer of the over 360 species of sharks as well.

Also upload the video how to mint this nft from frontend react.Thanks this video is Also awsome learned aLot❤❤

@imoto123 10 месяцев назад

thank you so much. This tutorial is the simplest and easiest to understand. I really needed this ❤

@maxcrypto1156 Год назад

Very good tutorial bro, but I 've a quesiton: when I try to Verify&Deploy the contract on ETHSCAN seem that miss the "contructor arguments ABI-encode". Can you help me to understand?

@QuickNode Год назад

There are a few options to solve this: 1. You can have the ABI generated by Hardhat 2. You can have it generated by Remix, if you use Remix 3. Or you can use a specialized tool for that, for example: abi.hashex.org

@maxcrypto1156 Год назад

@@QuickNode I used Remix but seems miss the last 0000xxxx part 🤔. Anyway thanks for replying me very useful guide!

@haldous2 Год назад

When you deployed that to mainnet, how much were gas fees per NFT? Nobody is talking about prices, and I am weighing the pros and cons of lazy minting + paying for freeze costs vs minting costs.

@QuickNode Год назад

This collection wasn't deployed to mainnet, it's on testnet. The gas fees for contract deployment transaction were 2,737,618. It should be about the same for mainnet. Depending on the gas prices, you can estimate the cost to deploy a similar collection to mainnet.

Who do you create json metadata? I have problem catching up that up that one. Please help. Apart from that Your video is very informative and quite understandable even for a person who start from the scratch. It's a very helpful stuff 👍

@Уважаемыйпользователь-ю9к 8 месяцев назад

Greate tutorial! Thank you very mush. I have one question. When i mint my nft, i cant find it on opensea. You have this problem? How to solve it?

@kryptokowboy2995 8 месяцев назад

Thank you. Very short and sweet. How did you prepare the .json metadata files? That was the only thing you kinda skipped over. I am just learning. Much appreciated!

@fawcetttattoo Год назад

I am stuck on 14:40 ... where did that screen come from. It's not a screen in Remix... so how do I finish this project if I don't what other app/software is being used. Can you help me out and tell me what/where to find this

@QuickNode Год назад

You need to store artwork somewhere. The screen you're taking about is for an NFT storage solution: nft.storage

@fawcetttattoo Год назад

@@QuickNode Thank you for the reply. I mean...The screen right after the NFT Storage... what screen is that? It's not Remix, right? Is it another coding website or program I should have?

@QuickNode Год назад

@@fawcetttattoo Oh, that's just my local development environment. I'm using VS Code. Using local instead of Remix because I need all the images, json files, etc.

@fawcetttattoo Год назад

@@QuickNode great thank you! I have downloaded the VS Code ... but now how do I do what you did with creating the json files in the VS Code? Do you have another video tutorial on that?

@pete275 10 месяцев назад

But how does the wallet know what NFTs I own? I see the get balance method only returns the number, but it there a way to get a list owned by a wallet? And how to retrieve the metadata of a token? I don't see that method either

@ayushkathayat1744 Год назад

hey isn't there any other way like i could batch mint all the nfts on metadata file without doing this much manual work

How do I mint 100 without doing it one after the other

@QuickNode Год назад

For batch minting, look into ERC721A. It's a variant of ERC721 specifically optimized for that. In fact, the more you mint at once, the larger gas savings. One of the parameters in a mint function in ERC721A is a number of NFTs to mint. You can read more here: www.quicknode.com/guides/smart-contract-development/how-to-mint-nfts-using-the-erc721a-implementation
