Run a Gravity Testnet Sepolia (L2) Node

Instructions about how to run a Gravity Alpha Testnet Sepolia node.

Due to the previous testnet being deployed with an alpha version of the software, an upgrade path isn’t available. You must relaunch your testnet node. In this migration, the testnet now uses Celestia’s Data Availability (DA) service via Celestia’s Nitro fork. If you run an external node, please deploy the updated configuration before the migration occurs.

Guide

Prerequisites

A local directory for storing node data
An Ethereum mainnet RPC endpoint with unlimited rate limit for eth_getLogs
An Ethereum beacon chain RPC endpoint
Celestia DA Service

Download Snapshot (Recommended)

Syncing a node from scratch can be extremely time-consuming and resource-intensive. We strongly recommend downloading our latest snapshot:

Running the node

Run the following Docker command (make sure to replace <some_local_dir> and <omitted> with your actual values):

docker run --rm -it \
