# How to Get an Arbitrum RPC Endpoint

Step-by-step guide to getting a fast, reliable Arbitrum RPC endpoint

Arbitrum One is the leading Ethereum L2 by TVL, hosting major DeFi protocols like GMX, Aave, Uniswap, and Camelot. If you're building on Arbitrum, you need a reliable RPC endpoint that can handle the network's high throughput without rate-limiting your application.

### Features

* **EVM-compatible** — use the same tools as Ethereum (ethers.js, web3.js, Hardhat, Foundry)
* **Archive data** — full historical state queries
* **Trace & Debug** — `debug_traceTransaction` and related methods (Starter+)
* **WebSocket** — `wss://shared.eu-central-1.getblock.io/<TOKEN>/` for real-time subscriptions
* **Multi-region** — Frankfurt, New York, Singapore

Once logged in:

1. Click **"Shared Nodes"** in the left sidebar
2. Click **"Create New Endpoint"** or the **"+"** button

4. Click **"Create":** Your endpoint URL will be generated immediately.
   {% endstep %}

{% step %}

#### Copy Your Endpoint URL

Your endpoint URL looks like this:

```
https://shared.<region>.getblock.io/a1b2c3d4e5f6789012345678abcdef01/
```

{% hint style="warning" %}
`<region>` is `eu-central-1` (Frankfurt), `us-east-1` (New York), or `ap-southeast-1` (Singapore) — whichever you picked in step 2.

The long string after the host is your **access token** — keep it private.
{% endhint %}
{% endstep %}

#### Test the Connection

  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
```

{% endcode %}
{% endtab %}

{% tab title="Response" %}

```javascript
import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider("https://shared.eu-central-1.getblock.io/<YOUR-ACCESS-TOKEN>/");
const block = await provider.getBlockNumber();
console.log("Latest Arbitrum block:", block);
```

{% endtab %}

{% tab title="Python" %}

```python
from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://shared.eu-central-1.getblock.io/<YOUR-ACCESS-TOKEN>/"))
print("Chain ID:", w3.eth.chain_id)  # 42161
```

{% endtab %}

{% tab title="Viem" %}

```typescript
import { createPublicClient, http } from "viem";
import { arbitrum } from "viem/chains";
