+This repo contains the Scroll bridge.
+
+In addition, launching the bridge will launch a separate instance of l2geth, and sets up a communication channel
+between the two, over JSON-RPC sockets.
+
+Something we should pay attention is that all private keys inside sender instance cannot be duplicated.
