I'vetried evrything i could but cannot how to solve this error ... sorry i not a dev pro

[yuichiroaoki]

Sounds like a problem with ALCHEMY_POLYGON_RPC_URL.

Did you create a .env file with that? And is that absolute url?

[h4ckm1n-dev]

Thanks, you very much for pointing that out ! that was the <> i didn't delete in the alchemy url !

now the deploy is finishing with : Solidity compilation finished successfully Debugger listening on ws://127.0.0.1:42043/c21fcfcd-231f-4dbd-842d-506c6f72f1e6 For help, see: https://nodejs.org/en/docs/inspector Debugger attached. contract deployed to: 0xd544d7A5EF50c510f3E90863828EAba7E392907A

But i didn't pay any matic for the creation, and it is shown as an address and not a contract ? is that ok ?

seem that i still have the privatekey entern incorectly beacause when i launch "balance" i got this output

Error HH306: The '--account' parameter expects a value, but none was passed.

[h4ckm1n-dev]

solve this issue using npx hardhat run scripts/deploy.ts --network polygon. you can close this issue

Thank you very much
