Base is a secure, low-cost, developer-friendly Ethereum L2 built to bring the next billion users onchain. It's built on Optimism’s open-source OP Stack.
This repository contains the relevant Docker builds to run your own node on the Base network.
We recommend you have this hardware configuration to run a node:
- a modern multi-core CPU with good single-core performance
- at least 16 GB RAM (32 GB recommended)
- a locally attached NVMe SSD drive
- adequate storage capacity to accommodate both the snapshot restoration process (if restoring from snapshot) and chain data, ensuring a minimum of (2 * current_chain_size) + snapshot_size + 20%_buffer
Note: If utilizing Amazon Elastic Block Store (EBS), ensure timing buffered disk reads are fast enough in order to avoid latency issues alongside the rate of new blocks added to Base during the initial synchronization process; io2 block express is recommended.
If you encounter problems with your node, please open a GitHub issue or reach out on our Discord:

- Ensure you have an Ethereum L1 full node RPC available (not Base), and set
OP_NODE_L1_ETH_RPC(in the.env.*file if using docker-compose). If running your own L1 node, it needs to be synced before Base will be able to fully sync. - Uncomment the line relevant to your network (
.env.sepolia, or.env.mainnet) under the 2env_filekeys indocker-compose.yml. - Run:
docker compose up --build
Note
To run the node using a supported client, you can use the following command:
CLIENT=supported_client docker compose up --build
Supported clients:
- geth
- reth
- nethermind
- You should now be able to
curlyour Base 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.
By default, the data directory is stored in ${PROJECT_ROOT}/geth-data. You can override this by modifying the value of
GETH_HOST_DATA_DIR variable in the .env file.
To load a snapshot you can extract the snapshot into the $GETH_HOST_DATA_DIR folder.
If you'd like to run the node in a single container instead of docker-compose, you can use the supervisord entrypoint.
This is useful for running the node in a Kubernetes cluster, for example.
Note that you'll need to override some of the default configuration that assumes a multi-container environment (OP_NODE_L2_ENGINE_RPC) and any port conflicts (OP_NODE_RPC_PORT).
Example:
docker run --env-file .env.sepolia -e OP_NODE_L2_ENGINE_RPC=ws://localhost:8551 -e OP_NODE_RPC_PORT=7545 ghcr.io/base-org/node:latest
You can fetch the latest snapshots via the URLs provided in the Base docs.
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 |
