+    make bridgehistoryapi-db-cli
+    ./build/bin/bridgehistoryapi-db-cli [command]
+```
+
+### bridgehistoryapi-cross-msg-fetcher
+
+Fetch the transactions from both l1 and l2
+```
+    cd ./bridge-history-api
+    make bridgehistoryapi-cross-msg-fetcher
+    ./build/bin/bridgehistoryapi-cross-msg-fetcher
+```
