+            You are withdrawing less than 0.01 ETH. Once your withdrawal is processed and available on
+            {{ eraNetwork.l1Network?.name }}, you will need to manually claim your funds which requires paying another
+            transaction fee on {{ eraNetwork.l1Network?.name }}. Transactions with higher value are finalized
+            automatically. We are actively working on making claiming available directly in the bridge UI.
