# Starknet

Starknet Sepolia Testnet guides powered by Pathfinder.

**Sepolia Testnet · `SN_SEPOLIA` · Pathfinder**

Operate a Starknet full node with Pathfinder. To participate as a validator, add registration and the separate attestation service.

## Requirements

| Resource        | Starting recommendation                                |
| --------------- | ------------------------------------------------------ |
| CPU             | 4 cores                                                |
| RAM             | 16 GB                                                  |
| Storage         | 1 TB SSD; more for archive history or snapshot backups |
| OS              | Ubuntu 24.04 LTS, x86-64                               |
| Runtime         | Docker Engine and Compose plugin                       |
| Ethereum access | Ethereum Sepolia WebSocket RPC (`wss://`)              |

Plan extra CPU, memory and disk space for heavy public RPC traffic. See [Pathfinder hardware requirements](https://docs.swmansion.com/pathfinder/getting-started/hardware-requirements/).

## Network and versions

| Setting                      | Value                             |

| Pathfinder network           | `sepolia-testnet`                 |
| Node container               | `pathfinder-sepolia`              |
| Local RPC                    | `http://127.0.0.1:9546/rpc/v0_10` |
| Reviewed Pathfinder release  | `v0.24.2`                         |

RPC is bound to localhost in this guide. The node needs outbound access to its Ethereum provider and Starknet data sources.
