### Manual Setup

Alternatively, you can add Base Goerli manually in MetaMask's network settings:

* Network Name: **Base Goerli**
* RPC URL: **<https://goerli.basescan.org/>**
* Chain ID: **84531**
* Currency Symbol: **ETH**
* Block Explorer URL: **<https://goerli.basescan.org/>**

### Update RPCs

Sometimes, the RPC endpoint for Base Goerli may not function properly, causing slow loading or even a complete lack of loading. To ensure uninterrupted use of the chain, it is recommended to have alternative RPCs provided by third-party services such as [**Alchemy**](https://www.alchemy.com/), [**Infura**](https://www.infura.io/), [**QuickNode**](https://www.quicknode.com/chains/optimism), and [**Ankr**](https://www.ankr.com/rpc/optimism/). A comprehensive list of RPCs and their status can also be found on [**Chainlist**](https://chainlist.org/chain/10).

#### If you encounter this issue, please follow the steps below to change the RPC endpoint:

1. Open your MetaMask and click **`Setting`**;
2. Select the **`Network`** section;
3. Choice the Network "Base Goerli";
4. In the "New RPC URL" field enter the new endpoint URL and **`Save`** the changes .
