i tried verify contract on sepolia testnet but it show error about full-blockchain-solidity-course-py HOT 7 OPEN

I find the right way to add sepolia to brownie , just use it and everything will be fine :
brownie networks add Ethereum sepolia2 host='https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID' chainid=11155111 explorer=https://api-sepolia.etherscan.io/api
I think we missed explorer for evm know where do you want to verify contract

from full-blockchain-solidity-course-py.

Got same error with sepolia

from full-blockchain-solidity-course-py.

I have a similar problem. The Rinkeby network is no longer working, I am using the Sepolia network. Up to now things have worked, but when I want to verify a contract problems come up. I have used the Keys API from etherscan.io . I add these API Keys to the .env file as explained in Vasiliy Gualoto's video time 6:27 (https://www.youtube.com/watch?v=yN3zpI3sNAE&t=23701s&ab_channel=Chainlink). I also updated the deploy.py file, but when executing the command in the terminal I get an error that I don't know how to solve. Here I show you the command and the result

Somebody has the same problem? I do not know what is the meaning of "Explorer API not set for this network".
Thank you!!

I forgot to indicate that I added the sepolia network to Brownie and it is displayed like this:

The following networks are declared:

Ethereum
├─Mainnet (Infura): mainnet
├─Ropsten (Infura): ropsten
├─Rinkeby (Infura): rinkeby
├─Goerli (Infura): goerli
├─Kovan (Infura): kovan
└─sepolia: sepolia

Ethereum Classic
├─Mainnet: etc
└─Kotti: kotti
.
.
.
Is it correct to see it like this? Could there have been an error adding it? Thank you!!

from full-blockchain-solidity-course-py.

what alternatives to rinkeby network can I use?

For my problem, after searching a lot, I found a solution and I was finally able to verify the smart contract in brownie. I went into .brownie\network-config and replaced the sepolia data with the following:

-chainid: 11155111
explorer: https://api-sepolia.etherscan.io/api
host: https://sepolia.infura.io/v3/$WEB3_INFURA_PROJECT_ID
id:sepolia
multicall2: '0x5BA1e12693Dc8F9c48aAD8770482f4739bEeD696'
name: Sepolia (Infura)
provider: infura

I redisplayed the contract and brownie verified it. I could check it at https://sepolia.etherscan.io/

I found this information at: https://ethereum.stackexchange.com/questions/147238/infura-network-support-for-sepollia-in-brownie

from full-blockchain-solidity-course-py.

I have kinda similar error with @hbarrabasqui it says

ValueError: Explorer API not set for this network

And I figured out how to set the explorer API. You just have to modify the network through the terminal:

\brownie_fund_me> brownie networks modify sepolia explorer=https://api-sepolia.etherscan.io/api

If your sepolia network has the same name as mine, it is supposed to be working well
