Thanks😊 for sharing it. Your teaching style is very good. I like how you explain in detail each related concept smoothly rather than rushing through topic fastly.

@BlockExplorerMedia Год назад

Thanks Aditya - I appreciate the feedback and glad you liked it.

@alexismollet6751 Год назад

I loved this video very new to coding and got stuck on some coding errors, but your explaining was very detailed and I watched the whole thing anyway

@suryarghyasaha4984 Год назад

I'm new to Blockchain Development and your videos helped me so much to grasp all the concepts so fast. You're an amazing teacher and I look forward to learning more and more from you. And since I recently made my own ERC20 token inspired by this tutorial, I sent some of them to the wallet address you mentioned in the descriptions. Thank You So Much man. Please keep up the good work.🙏🤝

@BlockExplorerMedia 10 месяцев назад

Thanks so much and congrats on your token. May I know the smart contract address so I can import the token in my wallet? Nice work : )

@AroseLove 11 месяцев назад

Amazing great stuff a few additional errors here and there (my own doing as only downloaded visual studio code today so was mainly extension errors) Thank you so much for this tutorial, there isn’t another started tutorial I’ve seen as good as this. 🙏🏻

@serjoka77 Год назад

Great Tutorial, thanks for sharing! One question: just curious why didn’t use the ownable extension of OpenZeppelin instead of creating a custom access modifier?

@andrecastro7817 Год назад

hey thanks alot for your video!! can this be deployed on the Binance Smart chian Network ? im trying to make one that taxes and gives reflections on each transactions.

@REZAZIMohamedabdessamed Год назад

Thanks for the quality explanation. I've a question, on the Transfer method I checked the original ERC20 implementation and they didn't multiply the amount input with the decimals... however it is still working (the balance got updated correctly).. how is that

@elmmacwebmobileapps Год назад

Thanks for teaching master. I appreciate. Question is, how do you give or set a value to the token. say 1000000 tokens, have seen in the tutorial wher it say 1000000 and value $0.00 | so ho do i change or give value to the tokens.??

@MikeDougherty Год назад

It's been a while, so maybe you realized this already, but at 1:10:00 the explorer shows two transfers. One for the 1,000,000 and another to a different address for 50. I assume that is the blockReward you were trying to find toward the end, no?

@ivanlagade Год назад

Continue making valuable content sir. God bless you more.

@galeraonthebeat Год назад

Why do we need ERC20Capped if we created the same function (_mint) inside our token contract? We do not have a function that overrides cap value so we could just use our cap value that we could declare in constructor.

@nosktech7818 Год назад

Can you show or direct me to adding the coding for a “creator reward” for receiving a percentage on every transaction , thank you great walk through 👍

@thatwasgaming6225 Год назад

@telego1151 3 месяца назад

Hey, thank you for the video, super thorough and helpful! One quick question though, is the coding the same for minting and BlockRewards now that Ethereum has moved to Proof of Stake or should we do anything different?

@jhhnadkins5669 Год назад

Hello, thanks very much for video. Process is same for bep20 token too? Can I find out? And can we add halving?

@deekshanayak5688 Год назад

Sir, your explanations have that clarity. Can I print token name,symbol on console like how you've shown the deployed address on console?

@MrPotatoHeadFX Год назад

Thank you for this. I was reading the solidity lang documentation and noticed that for large numbers it is ok to use 10e6 instead of 10000000 but when watching this and other videos no one seems to be using that style. Is there a reason why? my coding background is in matlab so for me its much easier, and cleaner to use the 10e6 notation

@advikmarini 11 месяцев назад

I am getting another error when I try to run "npx hardhat run --network rinkeby scripts/deploy.js" This is the error that I am getting: TypeError: no matching function (argument="key", value="deployed", code=INVALID_ARGUMENT, version=6.6.4) I understand that it has something to do with the ethers version that I am using, but I'm not quite sure what the substitute would be for "deployed" in the current version that I am using for ethers, and I haven't been able to find a substitute on the internet for this function. Thanks!

@williamwallace5707 4 месяца назад

Very in-depth, great tutorial. I was wondering what type of environment you are coding in. Are you using Docker, a VM, cloud or your PC? I am new to coding, very basic understanding and am concerned about installing and experimenting with various scripts/software and blockchain based things.

Derived contract must override function "_mint". Two or more base classes define function with same name and parameter types when I inherited those two contracts.

@24PetrocoinLLC 5 месяцев назад

can you include initial token pricing in the contract before deployment?

@officialjobsdekho5426 Год назад

bro which code editor should I use to install hardhat? I am not familiar with visual code. If you can make a video about visual code for deploying the contract it would be easy to understand.

@dannyellis971 Год назад

Just one question, To deploy my token. Do I just have to pretty much drag my Token.sol file over to Remix and Compile/Deploy in Remix? I tried it on the Goerli Test network and it all seemed to work well I'm just trying to get over the finish line here. Thanks so much

@kevinjurden9114 Год назад

Could you create a video showing how to create a Token, and instead of minting rewards to 'miners'. Create an Liquidity pool, and mint rewards to those who are staking? Could be implemented into a Defi/Dapp video

@hberrios23 10 месяцев назад

do you have any videos on creating a coin on different block chain network or all of the are the same?

@BlockExplorerMedia 10 месяцев назад

So far I've only done Ethereum, but the code would be the same for any EVM-compatible chain (such as Polygon). You would just create a network config specific to that chain in the Hardhat config file and then target that for your deploy. For something like Solana it would be totally different code and process though.

@jaspaw.5473 Год назад

Am getting an "import error" on my code which I don't know how to solve. I downloaded your source code and it is giving me the same error.... I have a feeling that something with my visual code IDE is not right. ,Could someone please help me with this, it's been stressing me out for hours now. Thanks in advance.

@jacektrocinski6337 7 месяцев назад

@47:00 I believe there's no need to duplicate the code in the _mint override of the token. Simply using super should suffice, as it will invoke the capped contract logic, which then triggers the ERC20 logic. This approach should maintain functionality without redundant code.

@ObscureOdysseys 11 месяцев назад

Alright so after a lot of debugging I actually got it to work on sepolia, what a great feeling! But, you never went back and taught us how to deploy on mainnet. Is it simply changing the infura endpoint link to mainnet link?

@BlockExplorerMedia 10 месяцев назад

Yes, exactly. I pinned a comment to the top explaining. A lot of people have been asking this. Thanks!

@shjndohjkaru Год назад

you can using sepolia for same

@BlockExplorerMedia 10 месяцев назад

A lot of people have been asking how to deploy to mainnet. In retrospect, I should have had that in the video! First add a 'mainnet' configuration in hardhat.config.js, under 'networks'. Then add your mainnet endpoint from Infura to the 'url' field. Finally target that configuration when you issue the deploy command, like this: 'npx hardhat run scripts/deploy.js --network mainnet'. Hope this helps.

Other testnets where phased out after the Ethereum 2.0 merge in Sept 2022. The recommendation is to use Goerli going forward.

I am new to Solidity , and I got to the deployment part, where I got this message: TypeError: no matching function (argument="key", value="deployed", code=INVALID_ARGUMENT, version=6.6.4) As I don't understand it fully, any help would be awesome. All files 7 are compiled successfully before that. I tried on Goerli and Sepolia net. I can share full error message. Hope for the best.
