hello everyone! i make tutorial from ethereum docs and get error when i run deploy. js What's wrong? I have 0.3 rETH on ropsten testnetwork, but it's too low for deploy???

Mar 14, 2022, 9:51 AM

Have you run it through ropsten network in your deployment command? Like -network ropsten

Mar 14, 2022, 10:01 AM

yeah i run it from command line: npx hardhat --network ropsten run scripts/deploy.js

Mar 14, 2022, 10:05 AM

Please share deploy script

Mar 14, 2022, 10:09 AM

Guys, is it support or scam?

Mar 14, 2022, 10:12 AM

scam

never ever ever send your keys to anyone

never commit in git etc either

but you do need a .env config in hardhat so
google that

Mar 14, 2022, 10:13 AM

i know this :)))

Mar 14, 2022, 10:13 AM

but it’s all local to your machine. nobody needs it

Mar 14, 2022, 10:13 AM

of course

Mar 14, 2022, 10:14 AM

Could you tell me why not to commit? Don’t really understand how they could extract data

Mar 14, 2022, 10:14 AM

it’s just bad practice, git is designed to share code, even if you delete later it’s in the history

it is to prevent a leak

Mar 14, 2022, 10:15 AM

you just asked why you should never share private key on a platform based on opensource?

Mar 14, 2022, 10:16 AM

Oh, ok got it, like if you ever commited private keys and remodel them later it’s still possible to get them, right?

Mar 14, 2022, 10:16 AM

yes

Mar 14, 2022, 10:16 AM

.env is the best solution😎

Mar 14, 2022, 10:16 AM

well he could use private repo and it’s still not wise

Mar 14, 2022, 10:16 AM

No, I thought it’s some sort of .git leaking too much info

Mar 14, 2022, 10:17 AM

yes of course as mentioned

Mar 14, 2022, 10:17 AM

of course
but I saw so many projects that got fucked

Mar 14, 2022, 10:17 AM

well nothings to say bitbucket or git won’t get hacked… or a build pipeline

either way - don’t commit wallet keys and usually api keys shouldn’t be - in many companies it’s sackable practice

Mar 14, 2022, 10:18 AM

Make a .env file and store all the private cide of the project.
After that give the path of the file in .gitignore

Mar 14, 2022, 10:19 AM

i make a .env file in project folder with api link from alchemy and private key from metamask. Then i take this parameters by hardhat.config.js

Mar 14, 2022, 10:24 AM

ive done the same, i wasnt after help - he was.

Mar 14, 2022, 10:26 AM

i dont understand how to solve a problem... i think that myNFT.sol file not linked to .env or somthing...

heh i deploy contract, but it's very expensive >0,5rETH...

Mar 14, 2022, 11:16 AM

You need to use your env information in the deploy script not in you contract

Mar 14, 2022, 11:20 AM

yeah, that is it. but why so expensive gas price for deploy? how make it cheaper?

Mar 14, 2022, 11:24 AM

I dont know how to make your contract less expensive, check what u sre doing. Maybe u have a big loop, to much transaction to storage...

Mar 14, 2022, 11:29 AM

eth is super expensive, the more code the higher the price

Mar 14, 2022, 11:41 AM

so 0,5eth for contract deploy is ok?

Heh, now there is 3 contract deployed... what wrong i do...

Mar 14, 2022, 1:43 PM

you should show the error
