🚀 Ethereum RPC's Speed Test

Measure and compare the performance of different Ethereum WebSocket (WS) RPC providers by monitoring how quickly they broadcast new block events.

Developed by Aero25x.

---

📌 Features

• Connects to multiple Ethereum RPC WebSocket endpoints
• Subscribes to new block headers (eth_subscribe)
• Logs the time each provider receives a new block
• Ranks providers based on first notification time
• Provides block count statistics over a customizable duration
• CLI interface for test duration

---

🛠️ Installation

Requirements

• Python 3.7+

• Dependencies:

  pip install websockets

Optional: Use a virtual environment for isolation:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

---

⚙️ Configuration

Open the script and edit the RPC_PROVIDERS list. Replace <API_KEY> placeholders with your actual keys:

RPC_PROVIDERS = [
    RPCProvider(
        name="Alchemy",
        ws_url="wss://eth-mainnet.g.alchemy.com/v2/<API_KEY>"
    ),
    ...
]

❗ Some providers require an API key or project ID. Make sure it's active and has WS access.

---

▶️ Usage

Run the script:

python rpc_speed_test.py

You’ll be prompted to enter a test duration in minutes (default is 5). The script will then connect to each provider, listen for new blocks, and display the results.

🧪 Sample Output

🏆 RANKING BY FIRST BLOCK NOTIFICATION:
1. Alchemy
   First block: #17945231
   Total blocks received: 23
   Delay from fastest: 0.000s

2. QuickNode
   First block: #17945231
   Total blocks received: 22
   Delay from fastest: 0.224s

...

📊 SUMMARY:
Fastest provider: Alchemy
Total providers tested: 4
Average blocks received: 21.5

🧠 How It Works

• Uses WebSocket connections to subscribe to newHeads
• Measures time of first block notification per provider
• Accumulates total block notifications over the duration
• Ranks and compares performance

---

📎 Notes

• This tool is designed for educational and diagnostic purposes.
• Provider speeds may vary due to region, load, and network latency.
• Add or remove providers by modifying the RPC_PROVIDERS list.
