Any idea what can cause this to happen?

```
$ npx oz balance

Hi @CrackerHax,

My first thought is that `gasPrice` is set very high in `network.js`.  
Are you able to share your `network.js`?

I was able to reproduce by setting the `gasPrice` to `5e18`.

## Deploy

Fails with high gas price.

```auto
$ npx oz deploy
Nothing to compile, all contracts are up to date.
? Choose the kind of deployment regular
? Pick a network development
? Pick a contract to deploy Box
✖ Deploying an instance of Box
Returned error: sender doesn't have enough funds to send tx. 
The upfront cost is: 25000000000000000000000000 and the sender's account only has: 100000000000000000000

```

## network.js

Default gasPrice is `5e9`.

```auto
module.exports = {
  networks: {
    development: {
      protocol: 'http',
      host: 'localhost',
      port: 8545,
      gas: 5000000,
      gasPrice: 5e18,
      networkId: '*',
    },
  },
};

```

## Box.sol

```auto
// contracts/Box.sol
pragma solidity ^0.5.0;

contract Box {
    uint256 private value;

    // Emitted when the stored value changes
    event ValueChanged(uint256 newValue);

    // Stores a new value in the contract
    function store(uint256 newValue) public {
        value = newValue;
        emit ValueChanged(newValue);
    }

    // Reads the last stored value
    function retrieve() public view returns (uint256) {
        return value;
    }
}

```

Hi @CrackerHax,

What network are you deploying to for development? I am using `ganache-cli`  
What version of OpenZeppelin CLI are you using.

If I use your gas limit, then I get `Exceeds block gas limit` for a regular deploy using OpenZeppelin CLI 2.8.

## network.js

```auto
module.exports = {
  networks: {
    development: {
      protocol: 'http',
      host: 'localhost',
      port: 8545,
      gas: 0x1fffffffffffff,
      networkId: '*',
    },
  },
};

```

## Deploy (regular)

```auto
$ npx oz deploy
Nothing to compile, all contracts are up to date.
? Choose the kind of deployment regular
? Pick a network development
? Pick a contract to deploy Box
✖ Deploying an instance of Box
Returned error: Exceeds block gas limit

```

Thing is I updated the contract maybe 7 or 8 times and it suddenly just started doing this.

Hi @CrackerHax,

Unfortunately I haven’t been able to reproduce through upgrades, I ran about 8 upgrades on my development network (`ganache-cli`).

Are you still getting the error?

</div>

I’m not getting an error message just a really high gas price. I am going to have to start over and redeploy all my contracts from scratch.

In Hardhat, setting the gas and gasPrice solves it for me!  
hardhat: {  
gas: 7000000,  
gasPrice: 1000,  
}
