I'm trying to simply deploy a smart contract in Kovan network, i've used the export of the ID using export WEB3_INFURA_PROJECT_ID=xxxx but i'm getting this error

ValueError: The method eth_sendTransaction does not exist/is not available

Taking a look into infura documentation, that method is not avaible. What i'm doing wrong?

Please take a look at this from the Infura community forums: https://community.infura.io/t/the-method-eth-sendtransaction-does-not-exist-is-not-available/1537


Looks like the problem was in brownie-config.yaml file, where i set the deployer address as cmd_settings / unlock. After removing the address from there, the deployment went OK. I guess i misunderstood the unlock feature!
