+    Bridge Mechanism:
+    1. Call [chain]_admin_lock_tokens(), to lock x amount of tokens from user.
+    2. Call [chain]_admin_issue_tokens(), to issue the locked tokens to layer-1 (escrow on ethereum).
+    3. Frontend will call `list_wallet_rewards --namespace [chain]_bridge` to get inclusion proofs.
+    4. Frontend will call claimReward function on escrow contract using the inclusion proofs given.
+    5. Receiver wallet will get the tokens after claim is done.
