Description

The MetaMask manual setup table for Base Sepolia has an incorrect and inconsistent first row.

Current (Base Sepolia table):
| Name | Sepolia |
| Network Name | Base Sepolia |
| ... |

The header row says Name | Sepolia which is neither a proper column header nor a data row. The equivalent Base Mainnet table uses Name | Value as the header and includes a Description row with value The public mainnet for Base.

Base Mainnet table for comparison:
| Name | Value |
| Network Name | Base Mainnet |
| Description | The public mainnet for Base. |
| ... |

Suggested fix

Fix the Base Sepolia table header to Name | Value and add a missing Description row:

| Name | Value |
| --- | --- |
| Network Name | Base Sepolia |
| Description | A public testnet for Base. |
| RPC Endpoint | https://sepolia.base.org |
