Where can in the repo can i participate in the after lesson challanges to mint the nfts??

[arod12345]

i am a little confused in where can i find these after lesson challanges,and thank you in advance

[EngrPips]

In the image above, I marked the section on the course repo where you can see the links to different chains to which the challenge contracts are deployed to

When you click any of those, it will take you to the etherscan page of the contract, click on the read contract tab and you will see a getter like that which i have marked.

When you click on the getter it will allow you to input the challenge number for which you want to solve and it will return to you the challenge contract address for that section. You can take that address look it up on etherscan and interact with it to solve the challenge.

Please ask questions if anything is confusing

thanks very much appreciate it

[EngrPips]

You are welcome.

Hi,
I've completed Sections 1 and 2, but I'm having trouble understanding what is the challenge. Is my understanding correct that I should be able to finalize the challenge after finishing each section? I'm not sure how to approach it or what exactly the challenge entails. For example, in Lesson 1, I don't see the getChallengeContract. Are there any videos or documents that provide more context on this?

[EngrPips]

The challenge is simply you interact with a deployed contract to mint an NFT to your wallet address. You can refer to my post above on how to get the smart contract address for the challenge of each section of the course

[ahpoh1349]

how to get the smart contract address please, sorry am still very very new tho i completed from start till section 2 and next is section 3 but still abit confusing on it as no exp in coding at all

but now all good ,managed to do it already

[EngrPips]

Hey @ahpoh1349, You successfully solved the challenge already.

[jodzares]

Thank you for the quick reply. I may have missed something, so I'm going back to the basics. In Lesson One, where is the getter?

Did I skip something? It's frustrating because this seems completely out of context after successfully completing Sections 1 and 2 with all tasks managed after each lesson. This feels entirely disconnected. Sorry if this is a stupid question, but I really want to understand how to proceed.

So, for Lesson One, what should I do to find out what the challenge is?

[EngrPips]

Did you provide the needed argument?

[jodzares]

Well actually it cannot be blank, you would have to put some char (although contract allows seems so based on code). Other reason could be if you havent connect your wallet (check my screenshot there is green - connected)

[EngrPips]

Good heads-up.

[umarusman5]

Did you provide the needed argument?
It asked twitter Handel, I just typed in that but the button didn't work

[EngrPips]

Check that you have connected your wallet.

[umarusman5]

Yes, I have connected

[EngrPips]

Thats weird. Show us a screenshot of what you are doing.

[umarusman5]

[jodzares]

Press that red button connect wallet :). Look, for example when I finally got it right, it was actually done correctly day before. I am out now, but when I come back I can send each step. Essentially solution would be connect wallet (you need metamask extension for your browser) and execute writecontract transaction.. Then you will get token and erc for NFT to be imported

[EngrPips]

Hey @umarusman5, Please do as suggested by @jodzares, and let's know how it plays out.

[codex-scribe]

I feel that @PatrickAlphaC should give a walkthrough of how to do this because I was trying to write contracts in remix to solve these challenges.

[umarusman5]

But I didn't receive the nft, do I need to do something more, in my metamask wallet I have the option to import tokens and when I click it, it prompts me for token contract address

[jodzares]

I mean it is real ether, how did it work for you?

I bridged some eth to zsync and paid small fee (because I wanted solve challenge there as well)

[EngrPips]

This kind of information cannot be found on zksync (or maybe I'm not checking it properly :) )

I have yet to check myself, but I will come here to inform you when I check to see if I can find anything.

[EngrPips]

Well I cant find contract on zksync-sepolia, link shared is for zkSync v2 (zkSync Era Mainnet) where there is a contract, however not possible to mint nft.

How do you mean it's not possible to mint NFT? Did you try, and it didn't work out?

I couldn't find either the contract or the token for importing NFT into my wallet. I expected to see them on explorer.zksync.io. Am I correct or missing something?

Have you check the logs tab as well? There might be some useful information there.

Sure, but no relevant info, also I checked other few transacs, same thing..

[EngrPips]

Argh, I will try myself, too, and see how it plays out

[KitsuneKode]

is it just me or the gas and transaction fees to solve the challenge is very high for sepholia???

[codex-scribe]

I tinkered with the fees. We'll see if it goes through.

[EngrPips]

It won't work because Metmask informed you that The transaction is likely to fail, which means something is wrong in your contract implementation or this transaction you are trying to send does not satisfy some conditions in your contract logic

[codex-scribe]

Hmm. This was just to interact with the challenge smart contract.

[codex-scribe]

It did not work in any case.

[EngrPips]

Check your implementation contract to ensure there is no error or mistake in it.
