Base

Instructions to set up your Base (Coinbase L2) node.

Requirements

• Setup your Axelar validator
• Minimum hardware requirements: 16GB RAM, 100GB+ free storage space.
• MacOS or Ubuntu 20.04 (tested on 20.04)
• Official Documentation

Prerequisites

sudo apt-get install jq -y
snap install docker

Configure and start node

1. Clone the Base repo

git clone https://github.com/base-org/node

2. In docker-compose.yml, set OP_NODE_L1_ETH_RPC to your own Goerli L1 RPC node. Using your own Goerli node is required to guarantee decentralization for validation.

3. Run:

docker compose up

4. You should now be able to curl your Base node:

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

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:

echo Latest synced block behind by: \
$((($( date +%s )-\
$( curl -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

You can check the latest block against the explorer.

Since Base uses the Optimism stack, you can review the Optimism Instructions for more details on expected log output and helpful rpc queries.

Configure vald

In order for vald to connect to your Base node, your Base RPC should be exposed in vald’s config.toml

[[axelar_bridge_evm]]

name = "base"
rpc_addr = "http://IP:PORT"
start-with-bridge = true
