Run a node

In this section, we will guide you through the process of running a Specular node, which consists of the consensus and execution layer clients.

Prerequisites

---

Install the following dependencies

• Node.js v16

• pnpm

• foundry

Build from source

To build, run the following:

# Fetch the repository and its submodules.
git clone https://github.com/specularl2/specular
cd specular
git submodule update --init --recursive
# Install dependencies and build binaries
pnpm install && make

Configure network

To configure a Specular node, you can just use an existing example from config as-is.

mkdir workspace
cp -a config/local_devnet/. workspace/ # copy all config files

Start an L2 node

../sbin/start_sp_geth.sh # Terminal #1
../sbin/start_sp_magi.sh # Terminal #2

At this point, you'll have the node started with the following parameters:

• L2: chain ID 13527, with a sequencer exposed on ports 4011 (http) and 4012 (ws).

To re-run the network from a clean state, run ../sbin/start_sp_geth.sh -c.
