1) If you are facing an error - "Migrations" hit an invalid opcode while deploying visit below
stackoverflow.com/questions/76377136/migrations-hit-an-invalid-opcode-while-deploying
2) If you are seeing the data in the form of 1n,2n then it is a Big Number object just convert it to String. You can use chatGPT as well to know more about it.
thanks dude i was litrally struggling on this since 2days

This is the best tutorial on the internet. I’m not exaggerating, I struggled to deploy my contract for two days straight following other tutorials. Thanks
How did you solved this problem ?? Can you please help me
A short, crisp and wonderful introduction to Blockchain development locally. At this point, everything is making sense w.r.t development 🎉
underrated. as hell need much more appreciation nice channels and videos
tried many videos on web3 coding, however this was the only one that gave me a clear view of the tools I could use and how i could use them effectively! :) finally got unstuck, thank you
Thank You so Much! I am new to Web 3.0 Development and this video really helped me setup a local environment for smart contracts with Truffle! Well Explained & Easy Tutorial!

Thank you so much bro. This helped to understand fundamentals really well! You're really underrated.
Clear, concise yet detailed... This is the tutorial I was looking for! Thank you so much!
Bro, your lessons realy help me in the study of blockchain technologies. Thank's a lot for you work.
Greetings from Estonia.)
That's great 😃

bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)
Error: *** Deployment Failed ***

Thank you. Solved.@@codeeaterweb3971
thank you so much you are the best in blockchain ;really the best one
I am not getting any value in the screen as well as on console.log (data shows 0n), Can you please help me on this?
When I debug and involing getter function, I can see below error

bhaiya tussi great ho....bahut help kardi aapne
Great Tutorial Sir
Learnt a lot
Thank You♥
y bro u have stoped making videos this video helped a lot man
kudos to your lucid explanation of concepts via code implementation!
I always get this error:
"SimpleStorage" hit an invalid opcode while deploying. Try:
* Verifying that your constructor params satisfy all assert conditions.
* Verifying your constructor code doesn't access an array out of bounds.
* Adding reason strings to your assert statements.
how do I fix this?

@@codeeaterweb3971 What if we add metamask as the wallet on the picture? How? Can you make a video for this? ToT
@@franclloyddagdag8900 metamask at the wallet?
@@codeeaterweb3971 Yes, instead of using the send({from("0x. . . . . . .. ")}) we could just put it in the metamask wallet, then use that. How should we do it, maybe you could do some tutorial for it.
Alchmey not offering goreli testnet, only sepolia testnet? Just stuck there how to go through it please
Yes go through it
pls how can we change it form goleri to sepoial or etherum because of alchemy it does not show sepolia

Thank You bhaiya
can you make a video on dapp making for P2P network?
Great job, very useful. Thank you very much! Although I have a question:
In case of deployment on a testnet, how function writedata should look like? I think account must be dynamically passed, right? I mean: methods.....send({from:....}); Also how can I update the value without refreshing the page? And one more question, how can I read an error message resulted from calling a function? (in case I have a function with a require statement that is triggered)
1) We can dynamically pass accounts by fetching accounts in a variable and then passing it as a parameter.
You can read the error message on the browser console or use a try catch block
I am getting this error while deploying. Please help. Stuck on here fro long.

Great video, very helpful thank you very much for great tutorial. If I may say, would it be possible to have full window showing the tutorial without the small window in the corner showing you teaching us. I am very very very sorry for this comment. I don't want to be rude but I am kinda distracted with small window i the corner. Other than that this tutorial is very very helpful. Thank you very much for making this video. But if no one else bothered, then please don't worry about my comment.
Thanks for the feedback;)
Hello Sir, This is really great tutorial. I have reached upto the last line of the code and my react JS is running fine. Both the getter() and setter() are working. Only a small problem is - the data I fetch is not being displayed on web page. I have tried to setdata for a constant value and it will be displayed after making setData(). Even the value returned from contract is displayed in Console But it is not going to be displayed on web page. What should I do?
Please the data convert it to a string
Done. Really Happy. Thank You So much@@codeeaterweb3971
Awesome sir 🤎....
sir!... could you please create videos for Decentralized Network Storage part (Pinata & IPFS ) .... 😊
I already have . See Decentralized gdrive project
@@codeeaterweb3971 Thank you Sir ... I will check it 😍
In Console, contract data it is showing data like 0n 10n 34n but it is not showing inside div, so please provide some Solution....
This is a big number notation. Just convert it to String.
@@codeeaterweb3971 How ??
Thank you for explaining every required thing in detail, but i am facing a problem regarding the value. Whenever i open localhost i am not able to see the initial value of (a) as zero and even after setting the value to 10, the space after smart contract remains blank. The problem which i am facing is at 1:22:13 in the video. Please help me to solve this problem.
Check your react part
On the localhost?? If yes, there are no message regarding error. And if you are talking about the code App.js then can you please tell me in more detail about which part of code i have to edit.
Thank you.
@@codeeaterweb3971 ??
you need to convert data to string: Contract Data : {data.toString()}
Migration hit an invalid opcode while deploying
See the pinned comment
You should make us a new video in 2024, I am new and I am trying to watch videos of blockchain and they are all old and I get a lot of errors. They are using old versions also.
Sure
thanks
Great tutorial! However, I had one question, when we migrate the contract, isn't the ETH for the first account supposed to be reduced? But it stays the same, 100 ETH, in the ganache. I would really appreciate if anyone could explain this.
Actually ganache does not show minute changes in eth. So if you will console the balance of account on terminal then it will show that balance is deducted.
@@codeeaterweb3971 I did tried console the balance on terminal, and it shows! But I am still not sure what do you mean by minute changes, does it mean I can actually see the changes after a long time? Also, thank you so much for the reply, I appreciate it!
@@studynowlah if there is a small deduction from the account like 0.01 eth kind then it will not show you. But if you do a transaction greater than 1 eth then it will be visible.It's about precision of ganache
@@codeeaterweb3971 I see, thank you so much for the explanation!
Delicious
how to input form data like user , age, number in a class instead of only one variable?
In the next dapp... I will show that
@@codeeaterweb3971 great. please add image or document to it with ipfs also
@@decadewgame9802 I have already. Please see decentralized gdrive video.

Plz do how we can add data into blockchain using ganache. Then we display it into table plzzzzzz
