Ethereum. Insufficient funds for gas * price + value

I am trying to deploy smart contract to mint NFTs on mainnet, after successful tests on rinkeby. While trying to deploy to mainnet the folowing error occured:

ValueError: insufficient funds for gas * price + value

I'm using brownie with Infura,and trying to mint ERC-721 tokens.

I would be grateful for any help!

Here's my console output:

Brownie v1.16.2 - Python development framework for Ethereum

NftProject is the active project.

Solution

  • Does your wallet have enough ETH on it to pay for gas? If you don't have enough ETH in your wallet, that means you cannot pay the gas fee when the scripts run. Place some ETH into your mainnet wallet and that will fix this issue.
