By <em>metered</em> we mean both <em>tracked</em> and <em>calculated</em>. By <em>handled</em> we mean how fees are <em>checked</em> and ultimately <em>deducted</em>.</p> <p>On the Monomer side, the problem we want to solve is two-fold:</p> <ol> <li><strong>Exempting the first transaction of every block from gas fees</strong> (the first tx in each block are Layer-1 deposits).</li> <li><strong>Translating the gas limit from the Engine API&rsquo;s <code>PayloadAttributes</code> to the Cosmos SDK</strong>.</li> </ol> <p>To tackle this problem, we need to take a step back and understand how gas is handled in the Cosmos SDK; first at a high-level, and then at a more granular implementation-level.</p>
