Gas Tracker

Your Ethereum provider - Metamask, should pre-fill the correct gas limit and the gas price, but sometimes the amount will be too low which causes transactions to last longer or not take place at all.

You can assert an optimal gas cost and adjust it in the transaction settings of your wallet during the transaction approval process.
