Conduit node

Conduit provides fully-managed, production-grade rollups on Ethereum.

It currently supports Optimism’s open-source OP Stack.

This repository contains the relevant Docker builds to run your own node on the specific Conduit network.

Software requirements

Hardware requirements

We recommend you have this configuration to run a node:

at least 16 GB RAM
an SSD drive with at least 200 GB free

Troubleshooting

If you encounter problems with your node, please open a GitHub issue or reach out on our Discord:

Supported networks

Network	Slug	Status
Zora Sepolia	zora-sepolia-0thyhxtf5e	✅
Zora Mainnet	zora-mainnet-0	✅
PGN Sepolia	pgn-sepolia-i4td3ji6i0	✅

Usage

Select the network you want to run and set CONDUIT_NETWORK env variable. You will need to know the slug of the network. You can find this in the Conduit console. For public networks you can use the table above. Example:

# for Zora Mainnet
export CONDUIT_NETWORK=zora-mainnet-0

Note: The external nodes feature must be enabled on the network for this to work. For the public networks above this is already set.

Download the required network configuration with:

./download-config.py $CONDUIT_NETWORK

Ensure you have an Ethereum L1 full node RPC available (not Conduit), and copy .env.example to .env setting OP_NODE_L1_ETH_RPC. If running your own L1 node, it needs to be synced before the specific Conduit network will be able to fully sync. Example:

# .env file
# [recommended] replace with your preferred L1 (Ethereum, not Conduit) node RPC URL:
OP_NODE_L1_ETH_RPC=https://mainnet.gateway.tenderly.co/<your-tenderly-api-key>

Start the node!

docker compose up --build

You should now be able to curl your Conduit node:

curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false]}' \
  -H "Content-Type: application/json" http://localhost:8545

Note: Some L1 nodes (e.g. Erigon) do not support fetching storage proofs. You can work around this by specifying --l1.trustrpc when starting op-node (add it in op-node-entrypoint and rebuild the docker image with docker compose build.) Do not do this unless you fully trust the L1 node provider.

You can map a local data directory for op-geth by adding a volume mapping to the docker-compose.yaml:

services:
  geth: # this is Optimism's geth client
    ...
    volumes:
      - ./geth-data:/data

Syncing

Sync speed depends on your L1 node, as the majority of the chain is derived from data submitted to the L1. You can check your syncing status using the optimism_syncStatus RPC on the op-node container. Example:

command -v jq  &> /dev/null || { echo "jq is not installed" 1>&2 ; }
echo Latest synced block behind by: \
$((($( date +%s )-\
$( curl -s -d '{"id":0,"jsonrpc":"2.0","method":"optimism_syncStatus"}' -H "Content-Type: application/json" http://localhost:7545 |
   jq -r .result.unsafe_l2.timestamp))/60)) minutes

Network Stats

You can see how many nodes you are connected with the following command:

curl -d '{"id":0,"jsonrpc":"2.0","method":"opp2p_peerStats","params":[]}' \
  -H "Content-Type: application/json" http://localhost:7545
