Running a node

Instructions to set up your Immutable zkEVM node.

Requirements

  • Minimum hardware requirements: 2 AWS vCPU, 4GB RAM, 100GB free storage space.
  • Ubuntu 22.04.1 (tested on 22.04.1)
  • Official Documentation

Prerequisites

💡Allowlisted Peering
Currently, peering with Immutable zkEVM is restricted to partners and requires that Immutable allowlist you either via WireGuard or static IP.
  1. Install Docker
  2. (Optional) If you plan to use WireGuard (see Get access to the Immutable zkEVM partner nodes), install it.
sudo apt-get install wireguard

Instructions

Get access to the Immutable zkEVM partner nodes

The Immutable zkEVM blockchain has dedicated nodes that serve as access points for partners wanting to peer with the network. Immutable protects these nodes from bad actors trying to disrupt partner services by putting limits on who can establish a connection.

Partners can choose between a static IP allowlist or a WireGuard tunnel to establish their connections.

The static IP allowlist ensures only a predetermined list of approved IP addresses can establish connections.

The WireGuard tunnel provides partners with a secure and private conduit for their connections to the Immutable zkEVM, without requiring a static IP.

Reach out to your Immutable point of contact providing your static IP. For example:

Please add my static IP to the Immutable allowlist: _STATIC_IP_

The Immutable team will reply with a confirmation that your IP has been added to the allowlist.

Setup the Immutable zkEVM node

  1. Create a data directory.
mkdir /opt/immutable-zkevm
  1. Pull the Docker image.
docker pull ghcr.io/immutable/go-ethereum/go-ethereum:latest
# Create a short-form tag we can reference in the next few commands
docker tag ghcr.io/immutable/go-ethereum/go-ethereum:latest geth
  1. Initialise the node.
docker run \
--rm \
-v /opt/immutable-zkevm:/mnt/geth \
--name geth \
geth immutable bootstrap rpc \
--zkevm testnet \
--datadir /mnt/geth
  1. Start the Immutable zkEVM node as a service
docker run \
-d \
--restart=always \
-v /opt/immutable-zkevm:/mnt/geth \
--name geth \
-p 8545:8545 \
geth \
--zkevm testnet \
--config /etc/geth/testnet.toml \
--datadir /mnt/geth \
--http \
--http.port "8545" \
--http.addr "0.0.0.0"

Verify your deployment

  1. Check the logs.
docker logs geth

An output similar to the following logs indicates you are synching from the genesis block.

  1. Check the chain ID.

From the container host.

curl http://localhost:8545 \
-X POST \
-H "Content-Type: application/json" \
--data '{"method":"eth_chainId","params":[],"id":1,"jsonrpc":"2.0"}'

Compare it to the output reported by Immutable nodes.

curl https://rpc.testnet.immutable.com \
-X POST \
-H "Content-Type: application/json" \
--data '{"method":"eth_chainId","params":[],"id":1,"jsonrpc":"2.0"}'

The output should be:

{"jsonrpc":"2.0","id":1,"result":"0x34a1"}
