Clear as usual, thanks Greg. Note: If anyone gets an error as I did at 21:12 ~ "Error: ENS name not configured (operation="resolveName" . . . it's because double quote are needed around the contract address instead of single quotes. It's a # not a string.
Thanks Greg. There are quite a number of great tutorials focused on MetaMask and Web3 but that presents a challenge. It's been tough to understand how to directly interact w/the contracts on the blockchain without a web browser. This clarified things quite a bit.
Incredibly helpful. Thank you. Moving to become a web3.0 Developer, and this is exactly what I needed. Multiple frameworks, overwhelming docs, etc made it intimidating. Your methodological approach is a testament to the strong fundamental knowledge you have,
i swear everytime i look for some help when i get stuck with code i end up with gregory teaching me, thank you gregory yet again you save me :) :) :) legend
On lessons 3 (51:03), what's the point of having `account1` variable (sender's address) if you'd never "use" the variable on the computation process? I mean we use our own PK and create the wallet based on our signing key then all is done. Do we really need the sender's account1?
Dear Gregory, I have got a question, How do you zoom into your screen without reducing the quality? ( on 16:41 ) do you use a special application or something? I need to know this, could you help me?!
Open a new terminal window, navigate to your project folder and run "npx hardhat node". You will have the network running in background while you perform your tests.
Hey Greg! Awesome content man!! I have a question, when trying to run the transaction (lesson 3) I get a processing error for insufficient funds. I do have the 0.1 ETH in the Kovan network so I'm at a loss. Do I have to specify anywhere in the script to look for the funds in the test network, not the mainnet?🤔
Thank you so much. Im able to connect and pull data from my smart contract ie. totalSupply. How do I format the output to display in html on my page instead of the console?
Hi Greg, nice video for ethers js. At lesson 4 when I run the app I am getting this error - Error: missing revert data in call exception. Please help. Thanks
in the video for example, you get an Error and you fixed it in the video, but didnot mention how to fix, i am getting the same error. can you please help me fix it.
hello, in the 4 exercice, we use contract.connect(wallet) to send Link from account 1 to account 2, we don't need it in 3 exercice cause it's ETH ? i'm right ?
Just experimenting. Can anyone let me know why the following 2 lines return different values for tx? console.log(tx); console.log("Raw tx after tx.wait():" + tx); The first produces exactly what Gregory is showing. The second line produces: "Raw tx after tx.wait():[object Object]" Thanks!
is there a way to make this transactions using truffle dashboard? i just got hacked after doing this copy and paste private key stuff, it seens very outdated, if we can do trasactions by signing them with metamask withou exposing the private key would be nice
is the infura id just the key that infura makes you? I substituted the "My First Key" value in and got Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.5.3)
You don't need 2 switch. At the end of the day it's just preference. People that are newer and often hardhat users tend to use ethers. Old folks which may still use truffle tend to use web3js.
Hi Gregory, thanks for the great videos! I have a question... The Private Key should not be exposed. I know we can use dotenv and .gitignore to hide .env files. But eventually, they make their way to the browser in the JavaScript where they can be inspected with developer tools. So, how can we protect the Private Key??? Thanks Gregory!
Hey Greg, great tutorial. After the merge, test networks like kovan, rinkeby are not working, so will be helpful if you can update the tutorial. Thanks!

THNX for your slogan turning people into blockchain masters ...
Def one of my first motivational pushes ... Great One Liner !
I cant belive this content is free! 10/10
Literally I am searching for this from past few days and today you make a crash course, thanks a lot 🔥💯🙏
Thanks, Greg. This is the best tutorial available on the internet about ethers js.

Do we really need the sender's account1?
Just really solid content. Nice work! Keep it up!
THATS MY BOYYYYYY, exactly what i needed, thanks gregory
I have been waiting for this.
The 'A' in ABI does not stand for abstract, it's
A - application
B - binary
I - interface
Brilliant to see you doing a vid on ethers, Greg! Superstar! I'm still missing the Tele on the wall, I hope yer finding some time to play it!!
man this is so gold. Thanks a lot for that
❤❤❤
👏👏🤝
thank you Greg! you made it easy to grasp etherjs
Dear Gregory, I have got a question,
How do you zoom into your screen without reducing the quality? ( on 16:41 )
do you use a special application or something? I need to know this, could you help me?!
zooming via laptop's touchpad
❤❤❤
🤝🤝🤝
the hardest part of programming is learning all these dependencies
A really helpful video, thank you so much about this
@33:03 How did you fix that error? I'm getting hte same thing. Can anyone help??
did you got the solution for that? I'm getting that same error.
hey did you get solution?
Open a new terminal window, navigate to your project folder and run "npx hardhat node". You will have the network running in background while you perform your tests.
Amazing tutorial!, thanks you so much for simplifying the complex.
Do I need to connect Wallet if you are not using transfer function?
Really great video! Learned so much from this!
Hi Error : I get the error @33.01 as Gregory shown but he not revealed to solve that, any help might be appreciated. Thanks in advance!!!
you rock G! keep up the great work! thank you again and again youre the GOAT for coding tuts bro!
Awesome tutorial! Thank you, man

Nevermind, I found it! Cheers!!
@@minipirate888 hey mate, I have the same problem. Can you tell us how did you resolved it ? Please.
@@DamageSoftware in your infura id, kovan should replace mainnet
Is there a more detailed ethers.js paid course?
can anyone tell me the name of editor he is using for coding
Thank you so much. Im able to connect and pull data from my smart contract ie. totalSupply. How do I format the output to display in html on my page instead of the console?
thank you so much for being born in this world!! :) love your work ❣
For those doing this tutorial now, use sepolia network for Lesson 4
Could I use a ganache instance instead of Infura and access the smart contracts I created ?
Great Video Greg, Thanks
Thanks a lot, Greg. This is priceless!
Hi Greg, nice video for ethers js.
At lesson 4 when I run the app I am getting this error - Error: missing revert data in call exception. Please help. Thanks
"your fan on your computer might start spinning so fast, and bad things are gonna happen" 😂such a mild humorous caution
How to solve error at 33:04
can you tell me what terminal you use?
Great tutorial - I found it very useful!
Sir what is the terminal used for this operation
Thanks Greg It was helpful
Sensei Gregory, thanks.
Doubt: we add await since we want that particular line of code or whatever to finish executing before moving onto the next. Am I correct?
Correct!!
in the video for example, you get an Error and you fixed it in the video, but didnot mention how to fix, i am getting the same error. can you please help me fix it.
How do I fix that NETWORK_ERROR I keep having? Can someone help me please?
Passing your "INFURA_ID" sholud work.
I've filled out the dap university boot camp form for years...I've yet to get an email on entry or pricing or anything
hello, in the 4 exercice, we use contract.connect(wallet) to send Link from account 1 to account 2, we don't need it in 3 exercice cause it's ETH ? i'm right ?
Just experimenting. Can anyone let me know why the following 2 lines return different values for tx?
console.log(tx);
console.log("Raw tx after tx.wait():" + tx);
The first produces exactly what Gregory is showing. The second line produces:
"Raw tx after tx.wait():[object Object]"
Thanks!
because you're concatenating string + object, and js
JSON.stringfy(tx)

the address he provided in this video no longer works. This one does 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2
Hi Friend, How we get all the imported account of metamask by ethers js
thanks Greg!
its still unclear to me why I would use ethersjs over web3js
You don't need 2 switch. At the end of the day it's just preference. People that are newer and often hardhat users tend to use ethers. Old folks which may still use truffle tend to use web3js.
@@nutz2599 i see thanks! I'm definitely more acquainted with truffle and web3js
Hi Gregory, thanks for the great videos!
I have a question... The Private Key should not be exposed. I know we can use dotenv and .gitignore to hide .env files. But eventually, they make their way to the browser in the JavaScript where they can be inspected with developer tools. So, how can we protect the Private Key??? Thanks Gregory!
Use metamask
is there a way to get contract abi automatically, without using the explorer?
How should I solve the JSON RPC internal error on metamask
How to Bulk transfer？
Hey Greg, great tutorial. After the merge, test networks like kovan, rinkeby are not working, so will be helpful if you can update the tutorial. Thanks!

Why dont you just use process.ENV.INFURA_ID and hide .ENV file. or Just create a test INFURA_ID and delete after video.
