I run this code in brownie: brownie run scripts/deploy.py --networks Rinkeby

deploy.py:

from brownie import network, config, accounts
from brownie import FundMe

def deploy_fund_me():
    account = get_account()
    fund_me = FundMe.deploy({"from": account},publish_source=True)
    print(f"contract deployed to {fund_me.address}")


def get_account():
    if network.show_active() == "development":
        return accounts[0]
    else:
        return accounts.add(config['wallets']['from_key'])



def main():
    deploy_fund_me()

It is not something related to your contract code, otherwise, it would not compile.

If your brownie-config.yaml setting names did not match you would get an error. then only thing it might be is publish_source=True

Remove publish_source=True. try without publishing. if you are on a development network, etherscan will not know about your development network

I ran into this issue as well. Any suggestions on help? My brownie-config.yaml file seems ok:

networks: default: development rinkeby: eth_usd_price_feed: '0x8A753747A1Fa494EC906cE90E9f37563A8AF630e'
verify: True mainnet-fork-dev: eth_usd_price_feed: '0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419'
verify: True development: verify: False ganache-local: verify: False

  • Figured it out. In my brownie-config.yaml i needed to set verify to false for the mainnet-fork-dev Jan 20, 2022 at 1:26

you need to set publish_source = False if on a mock network so that it does not try verify an API that does not really exist.

see this video 5h25! (its a long video) https://www.youtube.com/watch?v=M576WGiDBdQ

Make sure you are using the network flag when running your script.

Something like

Brownie run main.py --network YOUR_NETWORK_HERE
