Do you have enough eth to pay the gas and the contract for your collection?¿

[lbastian10]

i already paid ETH for deploying the contract. but could be that i dont have enough to cover the whole collection.
is it anyway to check what could be the price for the whole collection

mainnet appears on red but when i change to other network appears on black

thank you for your response

Hi @lbastian10, please avoid posting the same question multiple times. I already answered here.

About the mainnet appearing "red" that's correct. The main network is shown as red as a warning so the user knows that he must pay attention to what he is doing.

Also verifying the collection doesn't cost anything, so you don't need any ETH for this.

Please reply here if you need any further help with this.

thank you for your response, @liarco

probably thats what happening that i update some dependency or something but it was cause the couple of times that i tried verifying failed so i was trying to fixit.

i've been trying so many thing but always failed, even manually verification.

what would you recommend ? to make a new fresh contract

thank you so much

@lbastian10, I'm sorry but trying to get back to the original code you had when you deployed the contract might cost you more than deploying again.

If your only option is to deploy again, then here is what I suggest:

1. start from a brand new project folder
2. install all dependencies and make sure everything is working correctly
3. make all the changes to the configuration as explained in my videos
4. deploy and verify on the testnet without touching any file in your project
5. make sure everything works fine on the testnet
6. reset the contractAddress value in your configuration
7. deploy to the mainnet
8. update the contract address
9. verify immediately without changing any file

I hope this helps.
