Bridge

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.

Dependency

• install abigen

go install -v github.com/scroll-tech/go-ethereum/cmd/abigen

make bridge
