Hi, I moved to ^0.8.0 in order to use the OpenZeplin as is (without specifying the version if I were on 0.6.6)....but it meant instead of 'return' it is 'returns' but I think _setTokenURI was deprecated, but trying to figure out how to do it).....
Import and inherit this instead and everything should be the same github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/extensions/ERC721URIStorage.sol

Hey Patrick! Thank you for the Video! (I am starting to watch).
When you deploy your NFT contract on ETH, can you list that NFT token (or whole contract??) on opensea or rarible? And is than the auction mechanism already given by rarible or do we need to implement the actual method on our solidity contract? THANK you soo much for your response!
If you watch my longer video on this channel, all answers will be revealed!

Good vid bro
Hi Patrick, thanks for your video. I have one quest: if function createCollectible is called multi times at the same time, so these nft have same itemId ?
Nope! We increase the tokencounter each time. I might have forgot to add that in the video (oops), but in the repository of this video it's there!

Hi Alpha ! Thanks for the content ! Quick question ! after creating the token and deploying it to the blockchain. How can I then programatically sell the NFT without any intermediary exchange. Thanks in advance
Without an exchange, you’d have to find a seller and do it the old fashioned way. You’ll have to use some sort of smart contract that can programmatically do the exchange. Otherwise, you could make the exchange on something like opensea
@@PatrickAlphaC Thanks for your reply. Are you open to contractural work?
@@1990Farz nope, I’m flattered though :)

Hi, i have a problem:
When i run "brownie run scripts/simple_collectible/deploy_simple"
This error shows up: "brownie" is not recognized as a command
I responded to your other comment with this.
how do you add the packages to visual studio on mac ??
Which ones?
Hi Patrick! Quick question: any guidance on how to make two small changes: add "NFT_Max : 500" and "price = 0.0025 ether" ? The rest is boilerplate I just don't want to have to add the price to ever listing on OpenSea or wherever once I launch. Maybe I'm wrong about the price thing, am i?
Thank you so much for all you for the community, Bro!! Cheers, mate. Wil
Under your “mint” function do a “require” statement for “msg.value” to be the amount you want. Then, do another require for tokenCounter to always be below 500
at 0:48 what application are you using? I downloaded brownie via command but I dont know what application your using to display the framework
Download visual studio code code.visualstudio.com/
@@PatrickAlphaC awesome. Thanks for your quick response, appreciate it :)
Hi, how much does it cost to deploy 10000 nfts on polygon ?
I want firstly congrats about what you've done, in one week that should be a mess to additionate all these information... I've just a question, how can I set that I don't want any double, like with all my design associated, make the algorithm only do unique one and donc make double like two with the same attributes ? Thank you in advance and keep it up with your video about crypto that's so interesting that's a big Blue Thunbs like always
Appreciate the kind words. To do that depends contract to contract, but for this example you’d just never have a tokenURI set twice, and not allow the same tokeURI across pictures
Can you see the Simple NFT that is deployed or only the advanced one? I guess by see, I mean can you see it on OpenSea or anything?
You have to add the tokenURI for the simple one. I’ll show how to do that in the next video
I might be not familiar with the import itself. But how does the ERC721 get imported? I don't see the contract is downloaded. Thanks.
Brownie goes out to GitHub and download it
mate you are more HYPE then the FUD pump groups....
Thank you very much%!
Do you think I can run the same with the 0.8.7 sol version, please?
VS code tells me it's required.
You should be able to! VS Code is a little touchy with solidity listing, don’t worry about it too much
very useful! love your content mate! keep it up!
Would be keen to know how to add a limit for the amount of NFT's that can be minted.
Say the collection will initaially have 10 NFT's and each can only be minted 10 times (100 NFT's in total)
Is there a way to wrap the above around your code?
Sure! Just add something like “if tokenCounter > 9 then revert”
@@PatrickAlphaC thank you for this, it really helps.
Also, if i'd like to create 10 NFT's as JPG's (therefore using the simplecontract) am i right to think that i need to create 10 x createCollectible functions (1 for each type)?
I actually need to get down to it to see if i understood it right, just want to know if i'm heading the right direction :)
@@rotopercutorash nope! 1 createCollectible function works, just pass in a different tokenURI (pointing to a different image) each time.
Hey @rotopercutorash how did the creation of your code go? Wold yo mind sharing it? I also want to create something like you
Hi Patrick. New subscriber here great content! I see a lot of projects that have a "connect" button on their website to mint directly from their site. Do you have any tutorials or ideas on how to connect this python process with the process they are using via "connect" on websites? Thanks for your help!
Good question! That would be a full stack demo. Nader Dabit and dapp university have some good full stack videos, mine are coming soon!
Amazing Video! Is the best writing platform to download Brownie or is there another?
After i added 0x infront of private key i got an error: "ValueError: The private key must be exactly 32 bytes long, instead of 34 bytes."

Hi Patrick, i recived a nft from bakeryswap nft, but i don't know how yo see it o how to send, i just can see it on bscscan a it said si bep 721, but a i can see it un My metamask, can You help me plis? :(
You can call the tokenURI on the contract… although I’m not familiar with bakeryswap
Hi, can I hire you to make an nft for me? My mmorpg character can craft items forged with my account id making it unique compared to the same item that others can buy without though without my signature.

Say if someone mints from your contract paying a fee, do you have an example how you'd split the amount between multiple owners of the contract? I'm assuming the owner object only represents the one owner that deployed the contract so I'm curious how dev teams split between themselves via contract.
I don’t have an example, but you’d add a “withdrawable” amount for each address owner that tracks how much they can withdraw
@@PatrickAlphaC doesn't that involve hard coding all these addresses in the contract?
@@echadesi you could do it that way. But you could also have a “addowner” function that does it for you
@@PatrickAlphaC That sounds more elegant. Except I'll pay gas each time I call anything through the interface.

How can i run brownie without "brownie run script/create_collectible.py" , just i call "python create_collectible.py "?

@@PatrickAlphaC yea, i messed up during that part, thanks alot, will try again and see how it goes!
Hello, good video, how can I sell them with metamask on my page after creating them?
Like on your own website? You'd have to code that functionality into a front end. Basically have a function called "buy" where they can send you value and then you transfer them the NFT
please can you do a video on dapps for THETA, considering its EVM compatible with Solidity
ill try!
@@PatrickAlphaC Similar to the BinanceSmartChain and Matic/Polygon Ecosystem growth Theta is set to explode and itd be great if you could facilitate a part of it
Quick question do opensea automatic do this?
What do you mean? Do what?
What is the program that you used to write the code?
Visual studio code
Anyway we could mint these directly on open sea without having to pay for gas fees?
No, to deploy to a chain you need to spend fees
@@PatrickAlphaC So how does opensea do it with their collections? Their collection only requires a one-time gas fee and the rest of the mints are free. Is it because their collection is deployed on the ERC1155 chain? If so, is there a way we could deploy multiple NFT's on an 1155 chain and only paying a one-time fee? What is the best way to avoid high gas fees if I was to mint multiple NFTs at once? Maybe Integrate on the matic testnet?
Lastly, would it be possible to change the metadata on the NFTs that we've sold if the item was minted manually through opensea's website and not deployed by ourselves?
Please let me know and thank you for your amazing videos!
@@radripper9398 Erc1155 isn’t a chain. It’s a token standard. You have to pay fees everytime you mint a new unique NFT. The 1155 standard allows you to mint a thousand of the exact same token, not unique tokens, that’s the difference
there is no _setTokenURI function in openzeppelin ?
In the v4 versions, they have a different setup. You can still use the v3 contracts though!
@@PatrickAlphaC np i wrote the most stuff myself now just was wondering and searching
Fuck yes!
Bro I don't know anything about coding, if I do exactly what you do will the be good or should I have experience with coding first?
Do exactly what I do here: czcams.com/video/M576WGiDBdQ/video.html
@@PatrickAlphaC thanks bro
can anyone tell me please, what is the difference between creating an NFT here from scratch and creating it using Opensea??
Utility.
If you do it on opensea, it’s just an image. If you code it, you can give it unlimited customization. You can create a game like axie infinity or gods unchained. You can have true randomness and scarcity.
Doing it like this allows you to have it be more than a jpeg, and allows it to live forever
@@PatrickAlphaC Thank you so much, I have subscribed to see your content! just amazing man!
@@PatrickAlphaC one more question please, are there any fees to be paid when submitting the nfts?
@@MajdSukkar gas fees!
@@PatrickAlphaC sure, but I mean like how much. Or if you have a video on that topic, it would be great
Please remake this video on how to deploy with remix editor
It’s way harder in remix. I highly recommend learning hardhat, truffle, or brownie. This is going to make your life 50x better I promise
@@PatrickAlphaC ok I will learn it, we want more tuts please ...love your vids
But where are you coding,
I mean best app info please
What if you wanted to have 100 unique images as separate tokens under the same token tracker ?
Every time you call "createCollectible" they will be under the same "token tracker".
The NFT contract we deploy is known as the "factory contract", every NFT we "mint" in there will be of that collectible type.
So yes, if you called "createCollectible" 100 times here, they would all be under the same token tracker.
@@PatrickAlphaC how do you add a unique image to each of the NFTs we've minted?
@@PatrickAlphaC excellent response, and your videos extremely helpful and well made.
@@lukej7283 This video will show you how
@@PatrickAlphaC ah I see.
So in that json file I noticed there was multiple ID, 0, 1, 2 etc, so you would set tokenURI to one of these and it would assign the image that's in that file linked to that ID number as a function of this contract once its deployed.
Do you have a video on creating a tokenURI contract ?
Can you do a new video, the open zeppelin contract got rid of setTokenUri
You can still use 3.4!
