How to modify gas price on MetaMask (Gas Fee Saving Tip)🧑🔬
MetaMask defaults to suggesting gas prices of LOW - 1.0 GWEI, NORMAL - 1.5 GWEI, and FAST - 2 GWEI, These default settings can sometimes lead to paying excessive gas fees. Given that Layer 2 rollup solutions offer much more cheeper gas prices than traditional Ethereum transactions, we recommend following the steps below to adjust your gas price accordingly.
Initiate the transaction as usual.
Use the search bar at the top of the page to find 'Kroma'.
Click on the 'Add to MetaMask' button, and the verified RPC information will be automatically added to your extension.
To connect to Kroma, you can select it from the dropdown menu in the network selection section.
When you get to the reject or confirm wallet popup, there is an icon to specify gas price. In MetaMask it is "Market".
Typically you get multiple automatically filled options, and an advanced option where you set the values yourself. Click "Advanced".
Set a max base fee (0.1 gwei is typically recommended since it's extremely rare for the block base fee to reach this level). Then, determine a priority fee and click "Save". - Note: A dashboard to check the Gas Fee in real-time will be available in the near future.
Click "Confirm" to proceed with the transaction as you normally would.
