**Important:** SPECIFICALLY FOR METAMASK **you must set both the Max Priority Fee to 250 GWEI and the Max Fee to 250 GWEI or else your transactions will fail for both "approve" and "deposit**." Ignore the warning messages. This is not an issue for other wallets. Detailed below: &#x20;

To save the 250 GWEI setting for every transaction, head into your Metamask settings and go under "Experimental" and turn Enable Enhanced Gas Fee UI on.

When performing a transaction on Klap, select "Advanced" and save the gas fee as 250 GWEI in both fields
