Setup scroll client

Compile Binaries

git clone https://github.com/scroll-tech/go-ethereum /root/l2geth-source
cd /root/l2geth-source && make nccc_geth
mkdir /root/scroll-datadir

Create service to run Scroll Node

If possible, replace '--l1.endpoint "https://eth.llamarpc.com"' with your own L1 ethereum endpoint.

Logging

journalctl -fu scroll-node

Get Sync status via curl (replace $YOURIP$ with the IP of your server)

curl -H "Content-type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' $YOURIP$:8546
