[@CITYBOY5950]

I love how you don’t waste our time and keep the lessons succinct Great channel and explanations

[@TheHummChannel]

Halfway to flash loan

[@hernanphillip334]

HAHAHHAa how it turned out?

[@Bruhne]

Got it! I had been avoiding it for awhile because I didn’t feel I was ready for it. I’ll go back over it later or tomorrow, or both.

[@yellemonster]

This is the exact, specific tutorial I have been searching for! Thank you sir :D

[@kotlaarunkumar4251]

very informative n precise

[@videowizards1]

YOU ARE THE MAN

[@DeepKulshreshtha]

You kept it simple. That was helpful .. thanks.

[@matteotambussi]

great educational format!

[@jonyrambo8326]

easy to understand good to be teacher,,

[@NishantSingh-zx3cd]

Good work brother!

[@Bruhne]

I enjoy this payable stuff much more than working with arrays lol.

[@MrPrajyod]

We can also create Interface and invoke other contracts.

[@alidadgar445]

Hello. Thank you for your good tutorials. Please provide a tutorial on how to split a source file into smaller pieces of code in separate files. Thank you

[@TheVicj92]

Great video!! Question. What argument are you passing in when you use the contract type as parameter instead of contract address?

[@smartcontractprogrammer]

contract type is same as address

[@TheVicj92]

@@smartcontractprogrammer Got it. Thanks!

[@d.s.5690]

Very informative videos, thank you. I have a question, inside the getX method you say: TestContract(_test).getX(); This doesn't mean that you call the constructor of the TestContract? I'm a java dev and this looks like a constructor. I know that in Solidity a constructor is called only when you deploy a contract, and you cannot call it later.

[@ZAHID543]

Good work sir. Kindly make a video on call and delegate call .

[@sdfsfsfd437]

Great videos!

[@Ts2pc]

Very Good! It took me much time to compare this and the solidity 0.5 one.

[@masaa2906]

How about the encoding method? Could you do a video on that?

[@santiagoviana2671]

Good, thanks. Question: can I call deployed contract on mainnet or some testnet?

[@smartcontractprogrammer]

Yes

[@santiagoviana2671]

​ @Smart Contract Programmer Haha, thanks. But how? Is there an example? I would to use a deployed contract function for do a validation.

[@Xeway]

Thanks for this video, but I don't understand the difference with Interfaces :/

[@smartcontractprogrammer]

use call to call other contracts without declaring an interface

[@smnt]

What do you do if you're calling a method that is not defined in your code, e.g. the safeMint() method of an external NFT contract? Presumably those types won't work then

[@smartcontractprogrammer]

use interface

[@pitt8221]

Nice vid, is it possible to call contract function created by other people? If I have the contract address, function name and args. Thank you.

[@smartcontractprogrammer]

yes

[@crypto_peng]

what is the diff between this "Call Other Contracts" and using "Interface"? Thanks

[@smartcontractprogrammer]

Interface does require you to have the code of the contract that you're calling. Syntax is the same

[@Ts2pc]

Do we need to define a fallback function in Testcontract contract?

[@unaiiglesias9901]

is it possible to create a function in contract A, that only can be call by contract B? Thanks

[@smartcontractprogrammer]

Yes, require(msg.sender == contract B)

[@sql7002]

Thankssssss🙏🙏🙏🙏

[@karich21]

How do I call an existing contract using remix? The existing contract was deployed 3 days ago on remix's Javascript VM (London) environment. I have the contract's address. Thanks for your help.

[@smartcontractprogrammer]

Use interface and load the contract on remix

[@tnyamwanza]

How can you be contacted, I have some questions

You do awesome work, I love your channel, can you do another video like this using ethers js, especially the part about calling a payable function with arguments, thanks
