Learn to develop Solidity smart contracts by building 5 smart contracts, of increasing difficulty. Uses Remix, the online IDE for Solidity. Works on Windows, Linux and Mac, no need to install anything.
It will cover the basic Solidity features & syntax: declare variables, functions, visibility specifiers. After you watch this series you will feel comfortable coding beginner to intermediate smart contract in Solidity.
I am new to all this, felt to learn during free time of Covid Lockdown. Browsed many sites videos and found all beyond my learning comprehension. But this found to be very useful, step by step teaching is so fine and easy to understand. Kudos to the crisp and clean tutor. Thank you, I started to understand Solidity! Getting interested in.
Hey, thanks. I've tried following other tutorials, you explain everything in detail, like why am i typing, public, pure, returns, memory etc... Many people skip this basic stuff, but that is what i want to know. Thanks.
I agree with you man , the reasoning and explanation of each line of code is in detail Very helpful!
Thank you very much! Pretty well explained! I would say that Solidity is more similar to C (because its syntax, structures and compiling) but I have enjoyed a lot!
Good point!
Very well done. Thank you for sharing your knowledge in such an easy to follow and understand process.
Thanks for watching!
Great tutorial, worked perfectly for me, great explaining. Congrats.
Thx!
@j demitro it's not a mining tutorial. Its a blockchain smart contract development tutorial. You can create your own ICO with what you learn from the PRO course.
@j demitro if you want to create your own coin you need an ERC20 token and an ICO smart contract. I teach this in the advanced section of Smart Contract 30 on pro.eattheblocks.com
i realize it is kinda off topic but does anyone know a good website to stream newly released tv shows online ?
@Brock Kobe Try FlixZone. Just google for it :)
Thanks man, this tutorial is great, I learned a lot of information
Thank you so much.
You got so involved with solidity you even forgot to shave. Loved your videos and aI have learnt a lot from watching your videos.
Thank you so much man. you have great explaining
thats really nice support , gonna check this out. Thanks
Very useful for the beginners
awesome!
I'm a newbie. If you are too, this is worth following to give you a feel.
Hi dear Admin, could I ask you how to change Metadata in solidity 0.4.24 in order to compile a new contract with a different name, symbol, total supply? I have just got stuck. I do really appreciate it if possible kindly instruct me to sort out the problem and compile the file. Thank you, sir ☺
You are a excellent teacher.
thanks :)
Nice beared . i love it
There's a slight error with the last part I believe. Setting `nextId` to 1 is not enough. If we were to call `destroy 1`, it would set the id of `users[0]` to 0, which means that we can then find this id. This is also an issue because it appears `length` is not updated by `delete`.
To reproduce: `create 'one' -> destroy 1 -> read 0`. Since `delete` sets the default value of `id` to 0, we now have a valid `id=0` at position 0.
Are you talking of the crud smart contract?
I see your point. You are not supposed to read the users array directly, and also not supposed to read an id of 0, only from 1. We could add a require(id > 0) in the read function
@@EatTheBlocks yes. Calling read without arguments defaults to 0, so setting `nextId` to 1 isn't enough to ensure read is used correctly.
Thank you,very useful
function read(uint id) view public returns(uint, string memory){
for (uint i=0; i
< users. length(): it+)
{
if(users(i].id==id)
return(users(il.id, users[i].name);
I have an compile time error on for loop it’s says operator < is not compatible.
Amazing. Became a fan. I don't know if you are enough experienced on blockchain stuff to answer this question, if you are, please let me know: Can I (and if I can, how to do so) create a cryptocurrency that is backed on a wallet's eth balance?
hi julien how to get in touch with you ? i am interested for taking the training on how to become a blockchain developper
Great video as always dude
Appreciate it!
thank you and thank you with a lot of thank you. i can learn a lot from you vdo
You are the best. Thanks tons.
Hello there. I have a school project in which I am required to create my own blockchain using python. Pleases advise me on how TO MODEL THE DATABASE USING FLASK-SQLALCHEMY. Thanks.
Do you know how to create alphanumeric in solidity,using given characters and digits.
Thank s
I notice that in your video a users function is not automatically created when you create the users struct, is this a new feature that eliminates the need for the read function?
your videos and tutorials helped me learning so much... i created a lot of contrcts based on your videos... But now, i like to create a staking pool fo an existing token. A pool i can fill with f.e 1 mio token and running for 1 month.... can you make a tutorial for this? the token is not mintable
Great, Thank you
Welcome 😊
Thank you for explanations! Really good tutorial.
Do you have Test.js files? How do you even test your sol contract if test is not shown ?
Thx
sir
Thanks
Awesome man, thanks.
Glad to help!
Hi, is this the same content as the Blockchain Developer course on your Pro site? If different, how so? Thanks! I am struggling to find content that is up to date with changes in Solidity. I noticed this tutorial is a few years old now. How relevant is it still?
How do I benefit from this making a contact?
Hello, I'm building a contract right now and I was wondering if it is possible to trigger the swapAndLiquify with a Buy order. I've only seen this swap feature being triggered whenever someone sells the token. Would be nice to have it trigger after a Buy order so the chart will look healthier.
very helpful, thank you.
Glad it was helpful!
Which city is this?

Hello Julien (from the past). That is some beard you had on you.
you are teaching BSC smart contracts also or its the same ?
Recently I have done a couple of videos specifically about BSC, but its 99.99% the same. The only difference is the coin you use to deploy to mainnet (BNB tokens) and the url of the network.
Hey is the code still available for free on your website? I didn't see it there :(
i love you
haha thx!
@@EatTheBlocks i subscribed, i love how you break down everything in layman terms. Ill be sure to sign up for your classes very soon. I haven't checked out your other videos yet but i hope you can show us potential dapps that you can make on ethererum :)
@@miya7525 awesome, thx for the kind words:) I will upload some dapp tutorial this year as well :)
how can i deploy compile and run on vs code
You can't deploy on vs code. You need either to deploy with Remix (remix.org, shown in the video) or use the Truffle framework. I have a video to introduce the truffle framework here: czcams.com/video/M-w6dDDhu6w/video.html
And a full series on how to build a todo list dapp (smart contract + frontend) using Truffle, here:
czcams.com/video/-1c5hb_Y2MM/video.html
Says this course has been discontinued. You mind releasing the other 25?
You can still get it here:
eattheblocks-pro.teachable.com/p/dapp-30
if the parameter inside function set is string, we have to specify memory location, but for integer we don't have to. That's strange, even stranger than javascript, lol, need to dig deeper into solidity I guess
yes, Solidity can be tricky... strings have notoriously bad support in Solidity, so we try to avoid them.
Similarly in C, a string cannot be stored on the stack, since a string is a pointer to a series (string) of characters, thus they reside on the heap and have to be allocated for. In contrast to integers (and other primitives) that can be stored on the stack. I guess that's also the case in solidity because of it's constrained nature.
Hi Julien, I can't find "smart contract 30" on your website...did you remove it ? thanks
Yes, it's an old program. Was replaced by this one: eattheblocks-pro.teachable.com/p/dapp-30
@@EatTheBlocks Thank you, can I get an discount for this course ? I'm ready to buy it right now. Thank you.
i need to know if the "Full Smart contract 30 course" is part of the entire training course?
Smart contract 30 is an old course.
I updated it into Dapp 30:
eattheblocks-pro.teachable.com/p/dapp-30
But in the meantime, I released an even newer course:
eattheblocks.com/6-figure-blockchain-developer/
@@EatTheBlocks Is the dapp-30 still up to date and relevant or should I only consider the new blockchain developer course? I noticed that the blockchain course does not have the portfolio of the 30 dapps.
can we see the blockchain in remix
Remix is not a Blockchain explorer. Etherscan is a Blockchain explorer.
is the code the same if i want to make a bsc token?
Yes
@@EatTheBlocks could you also possibly make a video on how to burn tokens and add liquidity lock bro?
is this course updated?
soon!

next video ?
whats your question?
@@EatTheBlocks are there other video ?
@@zineelabidine6689 Other video... about which topic? I have a ton of video on my channel:

To be honest, this is a bad tutorial because it is too, even for beginners. It is artificially stretched to the length to force users to buy the other courses, which are more valuable I aussme... not good pratice. Everything you teached here could be teached in 30 minutes. And most of this stuff is just basic programming. The important stuff like mapping, events and imports you didnt even mention.
