Hey there, my name’s EdRoh. On my channel, you will find common coding algorithms and/or interview questions (with explanations of course). I also provide tutorials and courses on other programming topics in Web Development including Javascript, React, HTML, CSS, TypeScript, Redux, Node, Progressive Web Apps, React Native, Flutter, etc.
No matter what level you are, whether you are already in the software engineering field, or are just beginning coding in bootcamp or being self taught, my first and foremost desire is to help you provide with the best teaching content and learning resource I possibly can. As someone who understands the struggles of switching careers, I hope I can help guide you into this difficult but rewarding journey into engineering.

Really great content!
Slow and steady voice, without making the content feel slow or boring. Pointing out the essentials and some common mistakes 👍
Thanks for creating this video tutorial! Would love to see more of this especially how to create whitelist functions and how to integrate the contract into a mint site (frontend).
I'm a newbie and starting some courses to learn how create NFT's games and Art Collections and your videos are the most easy and professional to learn. Wonderful content!
Pretty under-rated channel, your explanation is just awesome, keep up the good work buddy! Thank you
Thanks for this excellent video !!!
I saw this comment on a reddit thread: "Limiting one mint per wallet address is pointless since anyone can just create another wallet address, claim the mint with that one, and transfer it back to their original address, thus circumventing any measures you put to limit the mint to one per wallet."
Thanks for your feedback!
Absolutely amazing tutorial! Your mic is clear and crisp, and you explain things in depth in a nice simple way. Def throwing you a sub for that one
Can you mint 10k without a contract? I finished my art, but now the hard part. Calculating rarity of each property. Then I'm planning to just mint one at a time until I hit 10k. I have watched many vids and am clueless
@@lmaculate5784 I got same issue mate.
Great tutorial! With clarity and completeness. Keep them coming👍
Dude! I have never understood anything this easily! You are awesome. Keep making more videos. Thanks for the treasure.
First useful video i've found, everyone else just advertise npm libraries. Thank you! looking forward to more content.
Great tutorial! I really liked it. Thank you!
best tutorial on this topic for now, thanks a lot
Thank you so much for giving me this great tutorial!
Excellent tutorial, well above many others
Very useful, teaching is simple and easy to understand.
Amazing and clear description Ed thanks
thanks. was searching for this. will recommend
Thank you for the video, at first I had 2 orange errors from the imports but it still let me deploy the contract and it still worked fine. Will be checking out your over video's!
It is easy to follow - I enjoyed so much!
one of the best videos i have ever seen on youtube.
This is fantastic! Thanks man, also pretty funny, I actually have met you before at UCLA, I'm Pat's friend ;) Pat said wassup
just awesome.. I liked the way you teach.. thank you
Awesome video, really appreciate the explanation and the simplicity of it. I am sure it is more complicated but I wonder how a random nft generator contract would work with this.
Thanks EDROH you have save my day, Thanks a lot
Very informative and easy to follow video - Really enjoyed it! Would really love to hear what testing methodologies you would suggest/propose before deploying a smart contract on mainnet.
This was super simple and helpful video on a simple token minting contract, thank you ☺
super helpful like usual, thanks!
this was my first ever tutorial ive seen for blockchain development :D thank you for the great content
Thanks bro, this is very educating
Salvation ! thank you for this simplified video , in fact before seeing your video, I had a model too long and complicated to understand, but had several options; like: MerkelProof - extensions- Counters- PaymentSplitter- ReentrancyGuard! is this necessary? or can we add them to our basic contract over time? Greetings 🙏🏻
Do a video on how to make a minting website also factoring in the minting button of course
would be very helpful
Yes it will be helpful
amazing tutorial!
great tutorial
it was so interesting how you used a local variable to save gad!
Hi Ed, Thanks for the tutorial. You're an excellent teacher! God bless you
Thanks for the tutorial Ed. What is the relationship between this code and an artwork? I minted a token, my address is in the mapping - great! but, where is the connection with the artwork that I supposedly bought? thanks!
Hi, hope you can do a full tutorial on how to use this smart contract on a NFT on a testnet or something.
Thank you!
hi, so if you want to deploy on main-net what do you do in the contract, also when creating the contract can you specify your ETH wallet address where you can receive payments to? Or do you have to come back to the contract to withdraw your money?
Thank you great content;
I have a question why the constructor is payable? The constructor is just setting the maxSupply.
The best tutorial I ever had encountered , now how Would you do it with and actually NFT image? Thank you
Thank you!!!
Bro, I love you, this tutorial is absolutely amazing, wish you best wishes and saying hi from Ukraine
This video taught me a lot and appreciate all you put into it but how does one determine how many one should allow to be minted? How do I determine what is best 2, 10, or 100?
Awesome Video. Can you make a Video about how to connect Metadata with the nft
Great video.. Can you tell us how this contract compares with real contracts in terms of complexity? How much difficult/complexed would be writing nft contracts for real projects?
Hey thanks for the video. I had a doubt that how we can make a digital art and post it on opensea testnet by remix, i will be eagerly waiting for your reply thanks
Thank you for making the difficult easy. I have a doubt, how do I put in the smart contract the address of the nft metadata? I mean the .json file where it says where is the image and the attributes of the nft.
So how are different nfts on the collection differentiated on this Smart contract You Made? I have to pay extra gas to add each 10.000 nfts from max suply to this Smart contract? And how can i add this to Open sea marketplace? Good video btw
solid!!! :)
Thank you for this, will you place make a playlist for making smart contract beginner course? thank you
So with this, will I be able to create an nft collectible for my collective?
Bro thanks your very much for this masterclass., really apreciate it. Question: Al this functions and variables works on the ERC115 contracts?, Another would be which is the function to neither thw owner or any one can change the max supply of the contract? , thanks n adcvanced
Thank you for this video, subscribed! I'm launching my first collection and trying to figure my first ever smart contract. Would you recommend to use this code for fixed price collection of 20? Am I correct saying is that the only thing I need to change in this code is the maximum supply and the price? Do you have any recommendations for collection of 20. I also don't have 5 wallet's to test, I have 2. I'm sorry for my very nubby questions 🙂
I’m trying to mint an NFT series of 10 on a smart contract like this. I wish there was a general code we could copy and paste for this basic idea
Can i ask what code environment do you use? Do i have to use the same because of environment requirements? Or i can use any code editor i want?
Is there a good reason for downgrading compiler version from 0.8.7 to 0.8.4? Thanks
Great to start. Is there any simple/minimal dev on this contract to add visiable NFT images/metadata?
I think it should be "baseURI". I will look into that.
So to be precise. The "is mint enabled" function when I set it to be true that is when the NFTs that are on opensea are available for sale right?
Well to be fair shape of you lody softs just like the first random notes that popped into Nice tutorials head
what would I have to change to test on the BSC or Polygon network?
Thanks for this, somehow I tried it and msystem won’t compile it, it’s saying I currently have no contract instances to interact with. Please help me, how do I solve that?
How can you add any metadata file and "Icon" or media thing to this smart contract?
Where does the token data come from that references the actual nft content?
How do you connect it to your website along with your NFTS
is it common to have a func to change maxSupply, which dilutes values of an NFT token?
I didnot understand the part at 14:05. Does it mean, every user should have only one wallet?
Great video. Thank you for making it super easy to follow. Can we get touch?
i haded a problem with a require code require(msg.value == mintPrice, 'wrong value'); its giving me error and can not compile an smartcontract
Pls sir number 33 totalsupply++; is showing error when I try to compile it
Where do they go? What token does it mint? Where does the mint appear?
dope
How can i add a lazy mint function to a ERC 115 contract? thanks sir
Pardon my ignorance but shouldn't you be minting from the same wallet? Thanks.
How can I learn how to write contracts? Where did you learn?
Do you offer any paid work like checking contracts ?
TDD guys, TDD will make your life easyer
Now How to make frontend after doing all this..Please make a video on that
can this be use on avalanche network?
thanks
I am not able to make this contract, syntax error shows up, kindly help me out!!!
Wait, so ur the one who did the phishing attack on opensea?
Super easy to understand tutorial. Do you have a tutorial on how to connect this contract to a minting website too?
I also suggest that you make your own discord, so that your follower can form a community that will help each other. 😁
but how pay in BUSD instead of eth?
And do you have a telegram solidity group I can join to get more of these 😊
😍
my code won't compile something to do w/ the totalSupply, weird
I got it
Make video how to make minting button
Like button count: 721
Now let's make it 1155
brrrr
How do you verify the contract on etherscan. When I tried to verify I get an error every time
Lol, developers write good comments
hi
my friend is playing with this cheat
12:10 why are you teaching
people how to make rug smart contracts HAHAHAH
5 lines in and I got an error => from solidity:
TypeError: Contract "SimpleMintContract" should be marked as abstract.
--> contracts/mintContract.sol:8:1:

8 | contract SimpleMintContract is ERC721, Ownable {

Any ideas why?
