Gas Price for Optimism

[cha0sg0d]

1. Gas submitted is 2 gwei, not 1 wei.
2. Need to have a nice way to switch gas for Optimism
3. There is this code snippet that seems wrong to me:

/**
 * Returns the given amount of wei in gwei as a number.
 */
export function weiToGwei(wei: BigNumber): number {
  return parseFloat(utils.formatUnits(wei, 'gwei'));
}
