Description

In the MetaMask manual setup table for Base Sepolia, the first column header reads Name but the first cell value reads Sepolia — which is inconsistent with the equivalent table for Base Mainnet, where the first row is a Description field.

Current (Base Sepolia table):

Name	Sepolia
Network Name	Base Sepolia
RPC Endpoint	https://sepolia.base.org
...	...

Base Mainnet table for comparison:

Name	Value
Network Name	Base Mainnet
Description	The public mainnet for Base.
...	...

Expected behavior

The Base Sepolia table should either:

• Add a missing Description row (e.g. A public testnet for Base.) to match the Mainnet table, and fix the header to Name | Value, or
• Remove the inconsistent Name | Sepolia row entirely.

Suggested fix

Replace the first row of the Base Sepolia MetaMask table:

| Name | Value |

And add a Description row:

| Description | A public testnet for Base. |
