Aurora blockchain transaction fees

How Aurora transactions work and how much they cost.
You need ETH for GAS on Aurora > 1 transaction cost roughly about 0.05$ but you need 0.0004 $ETH in your wallet because MetaMask still didn't updated estimated GAS trough RPC. Make sure to always have more than 0.0004 $ETH in your wallet or MetaMask won't let you confirm your transaction!!!
